Topical Finasteride Review | How to Make Your Own | Without Side Effects

topical finasteride review


Finasteride pill (brand name Propecia) is one of the only two FDA approved products for hair loss treatment, the other being minoxidil.  Topical finasteride has been explored by many users to lower side effects of finasteride pill. This blog will discuss (1) if the topical finasteride works, (2) whether its side effects is less than oral finasteride, (3) what is the best way to avoid side effects, and (4) how to compound topical finasteride yourself. 


Does Topical Finasteride Work?

For topical finasteride to work, it needs to be able to lower the dihydrotestosterone (DHT) level in the scalp, meanwhile it shall have minimum impact on the serum DHT level to avoid any side effects.  

In the 7th World Congress on Hair Research, a Dutch research group reported the effect of topical and oral administration of finasteride on  DHT levels in the scalp and serum. Results showed the topical finasteride not only decrease the DHT level in the scalp but also in the serum.  The good news is that topical finasteride decreases the scalp DHT level more than oral version does, meanwhile it has far less impact on the serum DHT level than oral finasteride. Thus the data supports topical finasteride works better than oral finasteride in two aspects: a) better hair growth; b) lower chance of side effects. 

  topical finasteride vs oral finasteride


 The results were confirmed by several clinical studies,  In 2012, a Thailand group compared the efficacy and safety of the 24 weeks application of 3% minoxidil lotion (MNX) versus combined 3% minoxidil and 0.1% finasteride lotion (MFX) in men with AGA. Results show the MFX group had significantly greater improvement than the MNX group in the amount of hair regrowth, and no side effect was reported (see the details of this study below, study 2).

 In 2009, an Iranian group compared the therapeutic effects of topical finasteride gel and tablet in treatment of male pattern hair loss, and found that the therapeutic effects of both finasteride gel and finasteride tablet were relatively similar to each other ( (see the details of this study below, study 3).


Topical Finasteride Side Effects: 

 Table below shows the drug-Related Adverse Experiences for oral finasteride 1 mg (Propecia) after one year use in a large clinical study (Nearly 2000 participants). This is the data submitted and reviewed by FDA when Propecia was approved. As shown, the side effects of taking 1mg finasteide daily is slightly higher than the placebo group (Read the more detailed finasteide side effects here

Decreased Libido 1.8 1.3
Erectile Dysfunction 1.3 0.7
Ejaculation Disorder (Decreased Volume of Ejaculate) 1.2 (0.8) 0.7 (0.4)
Discontinuation due to drug-related sexual adverse experiences 1.2 0.9


As the aforementioned data suggested that the systemic effect of topical finasteride is less than  that of oral finasteride. It does not decrease the serum DHT level as much as oral finasteride. DHT is an important sex hormone. Lowering the serum DHT level is believed to be the cause of sexual side effects by finasteride (such as decreased libido, erectile dysfunction) . A lot of people including some hair loss professionals believe topical finasteride has zero sexual side effects, which is most likely untrue. Keep in mind that even placebo could cause side effects as shown in a large clinical study for oral finasteride. But there is little doubt that topical finasteride is much safer oral finasteride. 


How to avoid finasteride side effects:

Topical finasteride helps reduce the chance of getting side effects. If someone still get unwanted side effects, one can avoid it by reducing the dosage. A big convenience of topical finasteride is that you can easily change the dosage. There is exactly 1 mg of finasteride in every 1 ml of 0.1% topical finasteride solution, which means you receive the same amount of finasteride in Propecia if you use 1.0 mL of 0.1% topical finasteride. If that is still too much for you, you use can 0.5ml (equals to 0.5 mg finasteride ) or even 0.25 ml (equals to 0.25mg finasteride). That can be easily done by measuring up less volume by the dropper that comes with the product.  When using finasteride pill, you will need to cut the pill, which is far less convenient.


How to make topical finasteride 0.1% yourself. 

If you want to make your own topical finasteride at 0.1 percent to save money, you should be able to do that with the right tools and material. No need to be a scientist to do so. The only tool you need is a scale that is accurate to 1mg level. All you need to do is to weigh 60 mg of pure finasteride power and pour it into a bottle of 60 ml minoxidil solution, close the bottle and shake it for 10 minutes.

The real challenge here is not how to make it but how to obtain good quality of finasteride material. Some people choose to use 5 mg finasteride pills (Proscar). In this case, you will need to pulverize 12 pills and then put the powder into a bottle of 60 ml minoxidil solution. Shake it very hard for 10 minutes. Let the bottle stand still for overnight and pour the clear solution to another bottle for use. The reason why it is recommended to dissolve the powder into a minoxidil solution is that it has right solvent that ensures the good absorption of the topical finasteride. You can't just use pure alcohol as the solvent, because it evaporates too faster and you will end up with flakes of finasteride on your scalp that will never be absorbed. 

With the 0.1% topical solution, you receive 1 mg finasteride if you use the solution once a day. If you use the homemade solution above twice daily, your finasteride dosage is actually 2 mg a day.


Where to buy topical finasteride:

You wish you could buy topical finasteride product from Amazon or Ebay like you shop for any other products. Unfortunately, neither Amazon nor Ebay offers it. The good news is that you can get it from our store with affordable price. Check it out here


Can I stop taking oral pill after I start topical finasteride 0.1%

Yes. You can stop taking oral finasteride pill (1mg) after switching to 0.1% finasteride and you should be able to main your results very well. 


Topical Finasteride Results:

You can view the topical finasteride results from our customers on the testimonial page. We have a lot of customers who enjoyed great success that they didn't have when not using topical finasteride. As one customer writes in his testimonial "I have tried numerous different hair regrowth products, Minoxidilmax's topical finasteride (Dualgen-15 NO PG plus) is the only product that did stop my hair loss and grew my hair back. Topical finasteride may not be for everyone. But if you have tried minoxidil and didn't receive good results, you should definitely try the topical finasteride. It is much more effective than minoxidil alone, and it is more cost effective than taking oral finasteride.". See the testimonial page here.

Topical Finasteride is a very controlled substance in belgium. Thus i Cannot import it from overseas. So I Made my own whilse looking how to get it here. Is it normal that there is a white layer on the bottom of the minoxidil/ Fina solution after i’ll Let the product rest for a night, before pooring it into an other bottle? ( used proscar 5mg, wich i pulverised pretty good into powder ) 

thanks in beforehand,

The  undissolved white stuff at the bottom is filler. Please do shake the bottle for least 10 minutes to make sure fin is completely dissolved.

Where do you reccomend I buy Finasteride powder? I have heard that it is far more effective as the pills contain other ingredients so wont be as potent/speard evenly.

Do you have any specific instructions regarding adding a 1mg fin pill compared to the minoxodil? How many pills should i crush down and add for use twice a day?

Thank you for a great article!

Hi There

I cut finasteride pills and add it into a bottle of propylene glycol free minoxidl and for some reason it won't dissolve. I had to end up putting the minoxidil in a small cup and using a spoon to break up the finasteride. I even add a new pill in a small 1/4 teaspoon of apple cider vinegar which dissolved it immediately and I poured everything back into my bottle. Unfortunately I can still see extremely small finasteride particles at the bottle of my glass bottle. Is there a reason the finasteride doesn't seem want to dissolve completely? I have put finasteride in water before and it is seems to dissolve almost instantly, which is confusing.

Also any recommendations on how to dissolve it 100%?


Thank you

hi James,

To use finasteride pills,  you really need to pulverize the pills before add it to a minoxidil bottle. You can pulverize the pill by using a spoon to crush it. The pills is mostly made of filler, the inactive ingredients, which includes lactose monohydrate, microcrystalline cellulose, pregelatinized starch, sodium starch glycolate, hydroxypropyl methylcellulose, hydroxypropyl cellulose, titanium dioxide, magnesium stearate, talc, docusate sodium, yellow ferric oxide, and red ferric oxide.

The "finasteride particles" seen in the glass bottle is unlikely finasteride. It is actually the filler. 

The concern with your process: using vinegar to dissolve the pill and then add the mixture to a minoxidil solution is that the vinegar is an acid, thus it will change the acidity of your minoxidil solution and may compromise its effectiveness.

The best way is to do as what described in this blog.

There isnt any topical fin in my country , I am thinking to use it by putting it into loreal serioxl 4-5 ml per 1 mg each day , is this would be effective ? or minox would be better ?

Loreal serioxl is the product line that has stemoxydine , which is believed be not as effective as minoxidil. Thus using a minoxidil solution as vihecle is a better option.

Hello i want to make a home made mixture of finasteride and minoxidil and i wanted to know how to do it. Can i buy finasteride powder and put it into a regular minoxidil bottle and shake it? How effective is this method? Thank you.

The key is to make sure the finasteride powder is fully dissolved. It is soluble in the regular minoxidil soluiton. But it does take time to dissolve it. It is recommend to shake the bottle for 10 minutes.

Assuming the finasteride powder you purchased is in good quality, the effectiveness of home made minoxidil + finasteride solution is described in the blog above.

How long should I leave this product on scalp? I use the No PG version but may switch to the PG version.

It is best to use the product in the evening so you can leave overnight and wash it in the morning.

Thanks for the great article! One comment: You recommend dissolving finasteride powder in a minoxidil solution which is fine. However, following your post I did some research and found that standard minoxidil solution (Rogaine) just contains alcohol (30%), propylene glycol (50%) and water as nonactive ingredients. 
So the only "secret"ingredient here that helps to increase uptake of finasteride is propylene glycol which is readily available everywhere and is indeed proven to increase the uptake and thereby efficacy of topical finasteride.

Quote: "You can't just use pure alcohol as the solvent, because it evaporates too faster and you will end up with flakes of finasteride on your scalp that will never be absorbed." So it should be easy to adjust the receipe to include 50% of propylene glycol or just use a minoxidil solution as you recommended.

hi Vanaik, You are right. You can make a solution that has 30% alcohol, 50% propylene glycol and 20% water mixture to dissolve as the solvent. You do not have to dissolve the finasteride powder in a minoxidil solution.

Finasteride side effects really freaks me out, even though I realize that people are way more likely to post negative reviews.  I wish more guys that have been taking finasteride for like 15 years would post about their expereriences and show their before/afters.  Bummer

I had side effects with oral fin. It's been 5 years since I switched to a topical finasteride and I have no issue whatsoever. Cheers

hi Ted,you are right that people who had sides are more likely to vent than those who are satisfied. If you read the clinical studies, you will see the finasteride side effects are pretty low, typically lower than 2%.
