Avodart For Hair Loss – The Pros and Cons of Using for Regrowth

Avodart has been proven to regrow hair by blocking DHT within the body. However, there are severe side effects associated with it… and as soon as you stop using it all the hair your regrew (and more) will quickly fall out!

In this article I’ll explain the pros and cons of using Avodart, so you can make a good decision about whether you want to use it. I’ll also give you some natural alternatives (which I highly recommend using instead.)

Two-thirds of American men dealing with some level of androgenetic alopecia by the age of 35, there are many men who are willing to try anything to regain their natural hair.

As with any type of prescription medication, when you start taking something new, you want to find out as much as possible about the drug.

That is why we have put together this helpful guide for men who are considering taking Avodart.

What is Avodart?

As with many prescription medications that are available today, Avodart can be used to treat more than one health condition.

Many times, doctors will find that a drug that is marketed to treat one condition, will end up having a positive effect on other medical issues.

The generic name for Avodart is Dutasteride. GlaxoSmithKline originally developed it to treat the symptoms of BPH, or benign prostatic hyperplasia, also known as an enlarged prostate.

The medication can reduce the size of the prostate and relive the symptoms associated with BPH such as difficulty urinating, the need to urinate more often, or the urgent need to go.

Since 2009, Dutasteride has been approved in South Korea to treat androgenetic alopecia, or male pattern hair loss.

However, it has yet to be approved for hair loss treatment in the United States, therefore it is commonly used as an off-label drug. Dutasteride is also known to be effective in treating female hair loss as well.

While it is commonly used for hair loss and many people have seen positive results after taking the drug, Avodart is controversial due to the potentially harmful side effects that are associated with it.

How Does Dutasteride Help with Hair Regrowth?

Men who suffer from male pattern hair loss or BPH both have a high level of the hormone that is known as dihydrotestosterone, or DHT. This hormone is produced from your body’s natural testosterone by the enzyme 5-alpha reductase.

Biochemical research has shown that men who have substantial hair loss and those who have BPH both have higher levels of this enzyme in their scalp or bloodstream.

Alternatively, men who do not have either of these conditions have much lower levels of the enzyme present.

Avodart works by preventing the effects of the 5-alpha reductase enzyme, which blocks the formation of DHT. That pauses a trigger element in the development of hair loss in men, as well as the development of BPH.

It helps to increase the number of scalp hairs and fills in the thin areas.

The results of taking Avodart will vary from one person to the next. Typically, users do not re-grow back all the hair that they have lost.

While DHT is a condition that occurs gradually, taking Dutasteride can help to delay the process of hair loss.

How Effective Is Avodart?

Dutasteride is known to have a much more powerful 5-alpha reductase inhibitor than the leading hair loss treatment Propecia, or Finasteride.

Propecia only inhibits type 2 and 3 of the enzyme while Avodart reduces the effects of type 1 as well.

A study that was performed by the Bernstein Medical Center for Hair Restoration that included 416 men with male pattern hair loss between the ages of 21 and 45 showed that Dutasteride was more effective than Finasteride.

The men were given various doses of Dutasteride, 5 mg of Finasteride, or a placebo each day for 24 weeks. The results showed that those who took 2.5 mg of Dutasteride had better results than those who were taking 5mg of finasteride.

On average, the men in the study could grow around 109.6 hairs while taking 2.5 mg of Dutasteride and those taking 5mg of Finasteride only grew 75.6 hairs.

What Do Customers Have to Say About Avodart?

Although Avodart is known for having potential side effects that can be very dangerous, the drug has received many positive reviews from all types of users.

Those who have seen the best results taking Avodart are on the 0.5mg pill. Testimonials include pros such as hair growing back thicker and fuller, few side effects, and reduced body hair growth.

But there is also an equal amount of reviews where users say that they have experienced a low sperm count, issues with their libido, and even some who have had their equilibrium thrown off.

And there are also many who experienced no good or bad effects at all. They still had thinning hair even after taking the drug each day for months.

Overall, most users will agree that Avodart is far more effective than Propecia, and there are plenty of clinical trials that back up those opinions.

Recent Studies Supporting the Use of Avodart

Although the drug is not approved in the US to treat male pattern baldness, many studies have been performed to find out how effective Dutasteride is in curing hair loss.

A study published on PubMed.gov in 2007 compared the effectiveness of Dutasteride in treatment of male pattern hair loss on identical twins. Seventeen pairs of twins were used in the study that took place over one year.

In the randomized, double-blind, placebo controlled study one twin was given 0.5mg of Avodart each day for 12 months while the other twin took a placebo.

The study looked at hair growth using before and after photos, hair counts and patient surveys.

The result of the study showed that Dutasteride improved the hair growth of the men taking the drug over the course of a year in comparison to their identical twin brothers who took the placebo.

Sixteen out of the seventeen sets of twins who participated in the study could easily determine who took the real drug and who took the placebo.

The clinical trial proved that Dutasteride reduced hair loss progression in men who had male pattern hair loss.

Another study performed in 2010 looked at the efficacy, safety, and the tolerability of Avodart 0.5mg. The goal of this trial was to look at the effects of the drug as well as how effective it was in treating male pattern hair loss.

153 men between the ages of 18 and 49 took part in the study. They randomly received 0.5mg of Dutasteride or a placebo for six months. Scientists looked at changes in hair counts, subject assessment, and before and after images.

Those who took Avodart during the six-month trial had a significant difference in hair growth and they also were all able to tolerate the drug well.

The Potential Dangers of Using Avodart

While there is a lot of talk about the side effects of taking Dutasteride, they are very similar to side effects from taking finasteride.

The reason side effects are so common with these drugs is because 5-alpha reductase inhibitors don’t simply reduce your DHT levels in the scalp.

They also reduce the levels of DHT all throughout your system. Which means that your hormone levels will be lower, which can cause issues such as…

  1. Impotence
  2. Low Libido
  3. Difficulty achieving orgasm
  4. Irregular ejaculation
  5. Low Testosterone
  6. Low Sperm Count

Since Dutasteride is stronger than finasteride, and can reduce DHT levels by as much as 95 percent (compared to finasteride 71 percent average), those who take Avodart instead of Propecia are more likely to experience these and other side effects.

While some men may be willing to live with low libido or a decrease in testosterone levels to regrow their hair, Dutasteride can also cause other, more serious, and life-threatening side-effects to occur.

The drug has been linked to an increase of high-grade prostate cancer over the years. That is because it can temporarily reduce the growth of benign tumors located on the prostate.

That masks the detection of early stage prostate cancer and delays the diagnosis until it is essentially too late.

Increased chances of side effects compared to placebo from 0-24 months

How Can I Get Avodart?

Recently the FDA completed the Phase II hair loss study for Avodart/Dutasteride. The results were released at the American Academy of Dermatology meeting held in San Francisco.

The results were very convincing, and the Phase III trials that looked at the drug’s effect on Benign Prostatic Hyperplasia have also been completed and are ready to be submitted to the FDA sometime this year.

This means that Avodart may be approved and marketed for hair loss sometime next year.

Until then, you can’t get Avodart prescribed to you by your doctor, unless you need it for other reasons pertaining to an enlarged prostate.

There are some places online where you can find more information on where to purchase the drug from an overseas provider, but you should do that at your own discretion.


Avodart has been shown in more than one clinical trial that it is a powerful alternative to Propecia in terms of reversing hair loss in men.

However, the fact that it is so strong also means that it comes with some serious side effects as well. Plus, it has yet to be approved by the FDA, at least for now.

  1. Been on Avodart for 5 years now. Great results. Zero side effects, in fact, I had more side-effects using propecia. Amazing results from both Propecia and Avodart though. I think Avodart leads the way, but not by a great margin!

    • Thanks for posting your personal experience here Ben. Still, for most of us the possibility of side effects are too much, but it’s good to know that some people don’t experience any.

  2. I am a 53 year young qualified pharmacist & chemist. on avodart 0.5mg for the past 10 years +. with zero side effects, only a full thick fuir of hair to prove it. DHT is the killer of hair-loss. not even minoxidil/loniten for high blood/p made a 2% difference, only side effects. worth the money every month…

  3. Switched from Propecia to Avodart when I heard about it’s increased ability to stop hair loss (Propecia stopped being affective) – OVER 10 YEARS AGO… have been taking Avodart daily for 10 years.

    And I don’t have any of the side effects (never have) that you mention. Sexual ibido is fine, sperm/ejaculation is amazing.

    Personally for a “hairlossrevolution” site I find your headline of 6 BIG REASONS I WOULD NEVER TAKE AVODART a huge disservice to your readers. Your 6 big reasons are nothing more than the MINOR AND RARE side effects that are POSSIBLE with the drug that most people don’t experience at all. Every drug is going to list their possible side effects.

    You basically wrote an article on how amazing the drug is, how every single study performed on it proves that it works, then you list 6 minor side effects as the cons. Sorry but they do not outweigh the vast amount of evidence and real reports from people using it that it works.

    Let’s put it this way – I was still losing hair in my 30’s with Propecia. I switched to Avodart. I don’t use anything else (Rogaine, shampoos, etc). After switching to Avodart there was a minor bit of regrowth but more importantly, my hair loss VIRTUALLY STOPPED. I have the same head of hair, if not a little fuller, at age 46 that I did at 30 when I was rapidly losing hair.

    Avodart works, and it works well. And the side effects are not experienced by many, if not most, on it.

    • Hello Eric, I appreciate your comment. You are one of the lucky ones who doesn’t experience side effects and it sounds like it certainly works for you. Personally I had some bad side effects using Propecia and that put me off it for life. But everyone is different.

  4. Hi, I’m living in the UK. I tried to buy dutasteride 2.5 mg. But couldn’t find online or any pharmacy. Can anyone help to buy it?

  5. I’m interested in hearing more about the hair loss that occurs when one stops taking Avodart. I’ve been prescribed Avodart by my doctor, but since I’m planning to try the Rezum treatment for BPH, I expect I’ll no longer require Avodart afterwards. For this reason, I’m holding back taking Avodart, because I heard the hair loss on Avodart cessation exceeds the increased hair growth. Would a slow cessation of Avodart over several months reduce the hair loss perhaps?

  6. I started dutasteride 5 weeks ago. I’m taking 1 – 0.5mg a week and continued with my finasterdine 1.25mg a day since 2 years ago (except sundays, taking dutasteride ) and every night I add topical minoxidil 5%.

    I’m experiencing a massive shedding phase and almost lost everything I gained with finasteride. Something similar but less shedding happened I started taking finasterdine and with minoxidil when I added it one year after starting with finasteride.

    I read many people posting their desperate need of advice and complaining that they just find the exact questions there posting but no answers or trying to find people just following up of there after results , but no luck. I would guess that the majority of people desist on continuing with the treatment, discouraged by the already mentioned, horrific massive shed.

    At this stage, and with the experience of the initial shedding phase of both finasteride and minoxidil, I would intuitively have my hope high that this will behave the same way as the other two (minox and fin) and recover my hair and maybe have even better results than when I started.

    The reason I added dutasteride was because I felt my hair quality was weakening and that the two (minox and fin ) weren’t that effective anymore.

    Starting this week I’m bumping the dose from 1 -0.5mg a week (Sundays) to two times a week (Sundays answer Wednesday) wich any of those doses are considered low and for some opinions not even enough to make a difference, but it is also said that shedding is a sign that it’s doing it’s job…

    I promise that in six months or if I see any changes before,even if no changes are seen. I will also add a pics of before finasteride and before dutasteride and 1 1/2 months after shedding started with dutasteride.

    I hope this helps!

  7. One major side affect of Avodart (Dutesteride) which is not mentioned here but which has been found in various recent studies, is that it causes NAFLD (Non alcoholic fatty liver disease) .
    I have been taking Avodart for the past 8 years to reduce the size of the Prostate any lack of hairloss would simply have been a bonus. I am now under investigation for NAFLD following recent Kidney Function Blood Tests and will probably have to stop using Dutesteride. I have been advised that it’s a side effect that you cannot escape if you are using it long term!
