MY 3 BIG Reasons NOT To Use Nioxin Shampoo For Hair Loss?

Bottles of nioxin products

Nioxin shampoo has been touted to reduce hair loss, but is there any truth to these claims?

In this article, I’m going to review the good and bad points of Nioxin (as scientifically as possible) so that you can make an informed decision.

But before I begin, I should start by saying one thing; I don’t personally use Nioxin, and I don’t recommend it to anyone who takes my hair loss course (Hair Equilibrium.)


In a word – chemicals – it’s full of them. (There’s a list of ingredients at the end of this article.)

However, I’ve tried to stay impartial and look at all the available evidence to see if it could work for others.

At the end of the day it’s your decision whether you use it or not.

Towards the end of this article I’ll show you what I use instead of shampoos like Nioxin.

HINT: What I use is 100% natural and works amazing if you have hair loss problems (and you can make it yourself at home.)

With my homemade shampoo recipe, you also know exactly what goes in to your homemade shampoo, and you can be sure each ingredient has been carefully chosen to improve scalp circulation, block DHT topically, boost nutrients and minerals and clean gently.

But I recommend reading this entire article before skipping to the end so that you can judge for yourself and make your own decision.

Why Nioxin?

A man applying nioxin

The Nioxin systems are a series of products designed to wash and cleanse the hair and scalp, and are marketed for the potential to reduce hair loss through the action of decreasing scalp sebum, inhibiting the production of DHT, and increasing scalp circulation.

Nioxin-bottlesThe products contain a significant amount of ingredients, many of which could be associated with severe allergic reactions and other side effects and should be used with some caution to individuals with skin sensitivities and known allergies to the ingredients.

The production of Nioxin products has been changed over time, and the original company sold to a larger manufacturer which may have reduced the effectiveness of the product.

While there are many potentially negative aspects to the Nioxin products, some of the ingredients have shown to have positive effects on hair loss and the underlying causes of hair loss.

There is a significant amount of ingredients in the current formula for Nioxin shampoo products, which can be both beneficial and detrimental to the user.

Many of the natural extracts may be able to promote overall skin health, reduce skin irritation and inflammation, and improve circulation in the scalp.

However, due to the significant amount of chemicals, like selenium sulfide and natural extracts the likelihood of allergic reactions or negative side effects can be significantly increased.

For individuals who are considering the use of the Nioxin products it is important to consult with their physician to determine the most appropriate method for treating their hair loss, thinning hair, or receding hairline.

What is Nioxin Shampoo?

Nioxin shampoo and the Nioxin line of products were developed to help address issues of thinning hair and hair loss, through the products capacity to address a few of the underlying conditions that cause these symptoms.

Over time, the product itself has been altered and adapted from its original formula and the line of products was ultimately sold to a larger manufacturer.

For people who are considering the use of Nioxin products, it is important to do the appropriate amount of research on the product and separate information that pertains to the original product from the current product.

What Are Sodium Laureth Sulfate and Sodium Lauryl Sulfate

Sodium laureth sulphate gives products a nice foam, but is it really helping the long term health of your hair?Sodium lauryl sulfate and sodium laureth sulfate are common detergents in a variety of personal care products, however they have come under some scrutiny due to some negative properties associated with them.

These chemicals have corrosive properties and are known as skin irritants. These products may leave skin dry and cause itchiness as well.

These substances are common allergens, and may be one of the leading causes of irritation caused by the use of Nioxin shampoos and cleansing products.

Potential Benefits of Nioxin Shampoo Products

  1. Reduced production of DHT, which is indicated in the negative impact of anagen production as it relates to the inability of the hair follicle to produce healthy hair
  2. Increased circulation and blood flow, helping the hair follicle receive the oxygen and nutrients necessary to effectively grow and maintain healthy hair
  3. Reduced inflammation of the scalp and skin, which allows for appropriate blood flow and decreases the impact of poor skin health on the hair follicle
  4. Reduced dandruff levels, which is a sign of unhealthy skin and over activity of the sebaceous glands
  5. Anti bacterial and anti-fungal capacity promote overall scalp health and prevent instances of seborrheic dermatitis which is a common cause of hair loss
  6. Reduced sensations of itching due to unhealthy skin, which prevents the likelihood that an individual will scratch and cause damage to the scalp and hair

Does Nioxin Shampoo Really Work?

Nioxin shampoo and the Nioxin system do not claim to be a hair regrowth product, but are designed to manage a couple of the underlying causes of hair loss.

If an individual’s hair loss is directly caused by the lack of effective blood flow to the hair follicle or the white buildup of sebum caused by DHT, then it is possible for some hair to grow back if it is addressed early enough and significant damage has not been caused.

peppermint-oil-nioxin-ingredientThere is limited evidence to suggest that some of the ingredients of the Nioxin products may stimulate hair growth beyond the capacity for Nioxin to promote blood flow and reduce sebum levels on the scalp.

Ingredients such as peppermint oil have been shown to have properties that may promote healthier hair growth, however further research is required to confirm these findings and gain more sufficient understanding of the mechanism of action through which this operates.

In this 4 week trial by Robin James he reported thicker, fuller hair. His barber also mentioned that his hair felt thicker (without any kind of prompting or mention of the product.)

However, I would highlight that this is only a short trial. The negative side-effects of the chemicals in Nioxin would take longer to take effect.

How Does Nioxin Shampoo Work?

Nioxin shampoo products support the health of the scalp, which ultimately promotes the health of the hair follicle and leads to the growth of thicker, more healthful hair.

There are two ways in which the Nioxin products may promote scalp health, by interrupting the process of converting testosterone to DHT and by increasing the circulation of blood flow through the scalp and to the hair follicle.

Nioxin is marketed as containing numerous herbs and botanicals that promote skin health and increase the circulation of blood through the vessels that connect to the hair follicles.

Healthy growth of hair requires sufficient blood flow in order to efficiently go through the process of cell division and hair growth.

Helping reduce DHT Levels In The Scalp

Beyond the need for sufficient blood flow, the scalp and hair follicles are also prone to negative impact from the buildup of sebum or the effects of DHT on the anagen stage of hair growth.

The inclusion of urtica dioica extract in Nioxin products increase the capacity of these products to reduce inflammation on the scalp, which can ultimately promote better circulation in the scalp.

In the Avicenna Journal of Phytomedicine the anti-inflammatory effects of urtica dioica are studied on animal models, and the researchers conclude that this product has considerable capacity to reduce and prevent inflammation.

Furthermore, the inclusion of menthol provides the enjoyable tingling sensation as well as reduces the sensations of itching associated with inflammation.

With reduced inflammation and decreased sensations of itchiness there is reduced likelihood that an individual will scratch their scalp which can lead to physical damage to the skin and may lead to hair loss.

Nioxin products may be able to promote skin and scalp elasticity and lead to healthier skin where applied.

In the journal Evidence Based Complementary and Alternative Medicine the authors of a study report that humulus lupulus extracts are useful in preventing the ageing of skin and can even treat skin that has become loose or begun to sag or stretch.

Similarly, the ingredient citrus paradisi (grapefruit) peel extract has been shown to be effective in its capacity to tone skin and promote overall skin health through reducing levels of yeast and lessen the chance for oily skin or the buildup of sebum.

The hair follicles which exist in the dermal layer of the scalp depend on the overall health of the skin to function appropriately and are prone to the buildup of bacteria, yeast, and sebum.

Increasing Blood Circulation In The Scalp

The ingredient, sodium citrate, is an effective anti-coagulant which allows for increased blood flow.

The Journal of General Physiology discusses the properties of sodium citrate, and determine that this chemical is an effective method for inhibiting coagulation without reducing the presence of calcium in the blood stream.

Since the sodium citrate is being applied topically to the scalp, the uptake of it into the circulatory system that supports the hair follicles will be minimal.

Due to the minimal uptake and the miniscule size of the capillary system in the scalp, this may be enough to promote circulation to the hair follicle without any significant negative impact.

According to an article published in Toxicology Research the extract of mentha piperita, or peppermint oil, has shown the potential to promote hair growth.

The authors of the study hypothesize that the oil induces a rapid anagen growth stage which led to increases in hair volume on rodents studied as compared to control groups.

There was a significant increase in the number of follicles producing hair, as well as the depth of the follicle and the dermal thickness.

Natural Oils Have Antimicrobial Properties

An article published through the US National Library of Medicine suggests that the essential oils that are ingredients in Nioxin products may have antimicrobial capabilities.

The mentha peperita (peppermint) oil and mentha arvensis leaf (tea tree) oil have been shown to reduce concentrations of bacteria and have minimal fungicidal properties.

The prevention of bacteria from growing on the scalp and within the hair follicle will promote healthier skin and hair follicles, which lessens the potential for negative impact on overall hair growth.

Another ingredient in the Nioxin cleanser product, camellia sinensis leaf extract, may have anti-bacterial actions that further the abilities of Nioxin to promote positive skin and scalp health.

According to a study published by the Pharmacognosy Review, the camellia sinensis ingredient may be able to disrupt the proliferation of bacterium.

This conclusion is based on a variety of past studies, and has not been performed in any human trials to fully understand the capacity of it as it relates to skin or scalp health. In fact, the conclusion of this article determines that further study is required.

Salicylic Acid Helps Remove Sebum From The Scalp

Salicylic acid can be used to clean the scalp and remove DHT

Another ingredient in the Nioxin cleanser product, salicylic acid, is a common treatment for numerous skin conditions including acne, psoriasis, warts, dandruff, and seborrheic dermatitis.

This ingredient is highly researched and widely available over the counter, and is included in a significant amount of skin treatment products according to PubMed Health.

The capacity to address dandruff and seborrheic dermatitis are the most relevant mechanisms of action for Nioxin’s ability to reduce the chances for hair loss or thinning hair.

While the targeted impact of Nioxin products is to promote circulation and reduce DHT levels, there may be some benefit from the other ingredients included in the formula.

These benefits are particularly related to the essential oils and natural products.

It is important to note that there is limited research on the effects of these ingredients as they related to hair loss and the growth of hair, and that further investigation is need to gain a more comprehensive understanding of the Nioxin shampoo products.

How Antifungal Capabilities Can Reduce Hair Loss

As mentioned above, some of the ingredients in Nioxin shampoo products may have antifungal properties, which may promote the overall health of the scalp and reduce the likelihood of associated hair loss.

In the journal Pharmacy & Therapeutics the authors suggest that addressing the colonization of yeast and fungus on the scalp can lead to skin irritations and conditions such as seborrheic dermatitis.

According to the National Institutes for Health one of the most common causes of hair loss and thinning hair is known as trichomycoses, which is caused by fungal agents called dermatophytes.

When dermatophytes are able to proliferate on the scalp this can lead to the loss of hair and the hair that does grow is more likely to be unhealthy.

The spores of the dermatophytes easily collect in the pores and hair follicles, which causes damage to the hair and will eventually lead to the hair falling out.

These types of fungal infections that could cause hair loss will often begin on one part of the scalp and can easily spread from one part of the head to another.

Seborrheic Dermatitis

According the journal Pharmacy and Therapeutics, seborrheic dermatitis is a chronic inflammatory skin condition that is highly common among the adult population.

Seborrheic dermatitis is also one of the most common causes of hair loss, due to the damage it causes to the scalp and the dandruff or scaling associated with this condition.

The mechanism of action for seborrheic dermatitis relates to the buildup of sebum on the scalp and within the pores, and is associated with the activity of the fungi Malassezia.

Nioxin shampoo addresses both the buildup of sebum on the scalp and within hair follicles, and reduces the proliferation of fungi such as Malassezia.

For these reasons, the regular use of Nioxin shampoo may reduce the onset or recurrence of cases of seborrheic dermatitis.

Role of DHT in Hair Loss

According to a study published by the National Institutes of Health, DHT or dihydrotestosterone, is a type of androgen that is produced in both males and females.

Androgens have a significant impact on the development and function of the sebaceous glands. The sebaceous glands produce a substance known as sebum, which can accumulate in the pores and follicles on the scalp and cause damage to the follicles ability to produce healthy hair.

High levels of DHT have been associated with incidents of male pattern baldness and female pattern hair loss, otherwise known as androgenetic alopecia.

While Nioxin shampoo and other Nioxin products are not a cure for androgenetic alopecia, the capacity to interrupt the production of DHT, and reduce the levels of measurable DHT, may help prevent the onset of this condition.

Importance of Blood Flow in Hair Growth

The scalp is full of blood vessels which supply the hair follicle with the necessary oxygen and nutrients required to effectively grow hair.

Hair that is unhealthy, brittle, or prone to falling out may not be receiving the nutrients required to maintain healthy growth.

Hair grows through a process of cell division, and the sufficient supply of oxygen which allows for the development of ATP. ATP is the form of energy utilized by epidermal cells, and enough of this is required for the cells to divide efficiently.

Potential Side Effects & Reactions of Nioxin Shampoo

The significant amount of ingredients, particularly the use of extracts from a variety of herbs and botanicals, increases the likelihood of allergic reactions to Nioxin products.

The cleanser also contains harsh detergents, sodium lauryl and sodium laureth sulfate, which may lead to irritation of the scalp and hair follicle potentially causing damage to the hair or hair loss.

If you begin to experience any of the side effects of Nioxin use, it is important to discontinue the utilization of this product and consult a medical professional if the reactions are severe.

The list of possible signs or symptoms of side effects caused by the use of Nioxin shampoo includes;

  1. Scalp redness or inflammation
  2. Scalp itching
  3. Scalp swelling
  4. Scalp flaking
  5. Scalp tenderness
  6. Dry, brittle hair

Reviews of Nioxin Shampoo

The combination of an herbal scent and the peppermint oils create a pleasant shampoo for daily use, and users often report enjoying the tingling sensation associated with the peppermint oil extracts.

As a daily use shampoo, Nioxin products also tend to provide a clean head of hair that smells good and does not appear oily or unhealthy.

Typically, users are left with a feeling of cleanliness and freshness they associate with the pleasant scent and cooling sensations of the extracts and the menthol.

According to a variety of users, the changes made to the ingredients and production of Nioxin products has decreased its functionality and user satisfaction.

The production of Nioxin products has moved outside of the United States, where it was originally produced, and is now made in Mexico.

According to long time users of the Nioxin products, the changes that have been made have led to an inferior product that is not similar to the original formulation in contents and results.

See my review of another kind of hair loss treatment product, Revivogen.

What Is The Cost of Nioxin Shampoo?

In order to achieve the best results from the Nioxin products, it is recommended that people use the full array of products in the Nioxin system.

A single month’s supply of the entire Nioxin system can cost upwards of $40 USD, which can become quite expensive as the manufacturer recommends daily use of the products for the best results.

It is possible to utilize just the daily cleansing product, which does contain the most effective active ingredients and may address the two most important components of reducing the production of DHT and promoting the circulation of blood flow to the hair follicles.

When compared to other products on the market that have similar effects and address the same issues, Nioxin products are one of the more expensive options available.

The Nioxin products are also intended for more frequent use than the other products, despite having similar reported outcomes when compared to products that are used less often. These factors will lead to a much higher annual expense than alternatives that are offered.

My Alternative Homemade Shampoos

No chemicals signAt the bottom of this page you’ll find a list of ingredients that make up Nioxin. What you’ll see is that it is absolutely full of chemicals.

In fact Nioxin is only made of harsh chemicals.

For this reason, I would personally never use Nioxin on my own hair.

Sebum buildup, dandruff, itching, bacterial overgrowth and hair loss are all caused by internal things coming from problems inside the body.

You cannot fix these problems by applying a shampoo to the scalp.

You will need to fix them internally through dietary and lifestyle changes.

Unfortunately, although these chemicals may help the problem in the short term, they mostly just cover up the symptoms. Over the long term they will just make the problem worse as the chemicals actually start to damage the scalp, dry out the hair and eventually cause hair loss.

The best solution I can recommend for you which has come from years of experience researching hair loss, and running this website is to stop using (shop bought) shampoo altogether.

The reason is, you can make your own 100% natural shampoo that cleans your hair, but doesn’t use chemicals.

The plus side is that this homemade shampoo is cheap, the ingredients are easy to find, it leaves your hair and scalp naturally clean but without stripping the natural oils.

However, you will also need to work on what foods your put in your body, so you will need to read the other articles here and download the Hair Equilibrium course to find out more about that.

To make your own amazing shampoo mix 1 teaspoon of baking soda with 1 tablespoon of apple cider vinegar inside a large glass.


Fill up the rest of the glass with water and stir until the baking soda has completely reacted and is no longer visible.

Take this mixture to the shower and and pour it over your wet hair. Massage the mixture lightly into the scalp and leave for 30-60 seconds before washing off thoroughly.

Bentonite clay

Bentonite clay

The next step (which is optional) is to take a teaspoon on bentonite clay and mix it into a glass of water. After washing your hair with the baking soda/ apple cider vinegar then pour the bentonite clay mixture on to your washed hair and rub into your scalp.

Again, leave for 30-60 seconds (or longer if you want) and rinse out thoroughly.

(Make sure you thoroughly wash out the shower after, otherwise your house mates will think you’re incredibly dirty:)

Inside my Hair Equilibrium course I’ll share with you some amazing twists on this shampoo recipe that work even better for blocking DHT directly on the scalp whilst also boosting circulation 100% naturally.

I would recommend that you take a look at all of the ingredients that make up Nioxin. Most of those ingredients have been added to the product to improve its marketability – but they won’t actually help your hair health.

Why not take the good ingredients and make your own shampoo from scratch so you know exactly what goes into it?


As you’ve just read I don’t personally use Nioxin shampoo and I don’t recommend using it if you have hair loss problems.

Making your own natural shampoo (whilst fixing your diet problems) is a much better alternative.

It’s also cheaper, and much better for the long term health of your hair to make your own shampoo which you can learn more about inside Hair Equilibrium.

Due to the significant amount of ingredients and potential side effects, it is important to monitor for any signs or symptoms of a reaction if you choose to go ahead with Nioxin.

Unfortunately, changes have been made to the original Nioxin formula and the product may not be as effective as it once was, which is only another reason to stay away.

As a fairly expensive option to treat the underlying causes of hair loss, Nioxin products do not appear to be the best option available on the market, especially when an even better all natural option is available.

If you are considering the use of Nioxin products it is important to fully understand this product and its intended uses. Due to the high potential for negative reactions, any persons with sensitive skin or known allergies should review the full list of ingredients.

If you experience any negative side effects you should discontinue the use of Nioxin products, and if you have a severe reaction then you should consult with a medical professional.

  • Annie Malkhassian says:

    After using barely 4 times, Nioxin Scalp Therapy System #3 Shampoo and Conditioner that my hairdresser recommended, my scalp started itching when I had just washed my hair, and I noticed an enormous loss of hair, and I mean a lot! I was using Argan Oil shampoo before, as well as Argan Oil penetrating oil from time to time, not at each washing though.

    I know without a doubt that I hardly saw any hair loss with the latter shampoo but felt that it was not hydrating my scalp as it should. This is the only reason why I went with Nioxin. It did not work for me and I will not continue using it. I even told my hairdresser just that and advised him to explain the side effects to people before they purchase the products and not lose $60 like I did because, no, the hairdresser is not reimbursing me!!

    • Will Hartfield says:

      Hi Annie, thanks for your feedback. This is really interesting. Clear evidence for people to avoid Nioxin. I would recommend making your own shampoos that contain all-natural ingredients instead.

      • Kathy Johnson says:

        I had a very similar account with NIOXIN.

      • Jazzy says:

        About 3 years ago I used this product while staying at my sisters house during thanksgiving. While in the shower I used the nioxin product my sister had for “thickening.” I applied the shampoo, then the conditioner as I would any other shampoo. However as I started to apply the scalp treatment my hair immediately started to fall off. I screamed for my sister to come into the bathroom. Once she opened the door she yelled, “Hey are you using my Nair. It smells like you are. ” I just started panicking.
        It was such a dramatic experience and for the next three years I had to cut my hair twice a month because it was so weak a uneven. My scalp was visibly burned on my forehead right on my hair line. I had serval bald spots but the product also managed to burn my hair off. It was as if someone took a pair of scissors and cut my hair with a blind fold on. Now my hairs long and my natural curls are back.
        Please I recommend everyone never to use this product.

  • Larry guske says:

    What diet do you recommend for psoriasis and hair loss- thank you

  • Jennifer says:

    I’ve been using this product for years on the recommendation of my hairdresser. Always have had very thin hair and never seen any positive response in my hair. However, lately my scalp is itchy. I’m torn on if I should continue using.

    • Will Hartfield says:

      Hi Jennifer, it’s a tough question. If you haven’t seen much positive response from using it then maybe you shouldn’t continue. The problem with these products that use chemicals is that they can help in the short term, but over the long term the chemicals disrupt the natural balance of the hair and scalp. They can negatively affect the delicate balance of pH and good bacteria on the scalp. I always advocate a natural solution. For you I would recommend trying a couple of tablespoons of apple cider vinegar no more than 2x per week. See how it goes.

  • Jessica mackey says:

    I’m so happy I read this article I’ve been using Nioxin. And not happy my hair used to be OK now I’m stopping this products immediately..thank you so much I’m gonna spread the word this is not very good.

  • Jane frey says:

    Thank you so much for this information.I was considering using it and now will not! Has anyone heard about the mona t system?

  • Val Pay says:

    Thank you for the information on Nioxin. I was just about to purchase this product. I have very sensitive skin and this is probably not the right product for me.

    • Will Hartfield says:

      Thanks Val! I would definitely recommend steering away from this kind of a chemical product, especially if you have sensitive skin. Incidentally, I used to have really sensitive skin as well, one of the things that really helped my skin, and stopping it from being really dry, was to start drinking raw goat’s milk kefir. See if you can get hold of some in your area.
