(60 ml is a 2 month supply)

  • Dutasteride:  0.1% (1 mg in each ml).


  • We offer DuDerma in two versions. One is formulated with proplylene glycol (PG), the other is without PG (PG Free).

    Both versions can be selected from the product Options (next to the product price). 

    If you are not sure whether you are allergic to PG, you can choose the regular DuDerma (~15% people are allergic to PG with symptoms such as itching scalp and skin rashes).

    If you are allergic to PG, Duderma PG Free is the best topical dutasteride solution without minxidil for you. 

    Duderma is a dutasteride only product. We have other topical dutasteride products enhanced with minoxidil and/or finasteride (See details below). 


  • Unit size: 60 ml (2oz). If you choose 60ml x 3, you will receive 3 units, each with 60 ml. 

    Concentration: 0.1% (1mg in each ml)

    Each unit comes with a dropper.

    If the concentration is too high for your usage, you can dilute DuDerma with the PG Solvent, or DuDerma PG Free with PG Free Solvent. If you mix one unit of Duderma with one unit of the Solvent, you will get 120 ml (4 oz) of 0.05% topical solution. To make a 0.025% topical dutasteride solution, you will add 20 ml of DuDerma to 60 ml of PG Solvent/PG Free Solvent.


  • Use up to 1 ml per application. Use no more than once  a day. 

    Each unit is 60 ml (2 oz). The product comes with a calibrated dropper. 

    One unit can last for at least 2 months.


  • It is usually abbreviated as Dut in hair loss community. It is a type I and type II 5α-reductase inhibitor (Finasteride is a type II 5α-reductase inhibitor only) . 5α-reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT). Excessive amount of DHT in the scalp is believed to be responsible for hair loss. The figure below shows how different products work for hair loss treatment. As shown, both finasteride and dutasteride work by inhibiting 5-alpha reductase, while other products such as RU58841,spironolactone, and ketoconazole work by preventing DHT from binding to hair follicles.

Can Dutasteride be Absorbed through Skin?
  • You may know the 500 Dalton rule, which says any molecule with a molecular weight (MW) over 500 Dalton is difficult to be absorbed through skin.

    Dut is 528.5 Dalton. Thus some people question if topical dutasteride is effective. An article discussing the 500 Dalton rule can be viewed here .

    In the article, it has the figure below. It shows the penetration rate of a molecule through a normal skin (NS) decreases rapidly when the molecular weight (MW) is over 500 Dalton. However, the rate does not become zero until MW reaches 600 Dalton. The penetration rate of dutasteride (mw: 528.5Dalton) is estimated to be still >50% if the figure is accurate. This means it can be absorbed through skin, althought it may not be as fully as smaller molecules. 

    In addition, we have no doubt that Duderma can penetrate skin based on the feedback of our customers (see the product review at the end of this page).

    Can I mix Duderma with other topical solution solutions you have and use it together?

    This product is miscible with any other topical minoxidil/finasteride solutions we offer and you can mix them in any ratios. 

    For your convenience, we also offer a product containing Dut with minoxidil (brand name MinoDuta), and a product containing Dutasteride, finasteride, and minoxidil (brand name FinoDuta). 


    How stable is this product? 

    Topical dutasteride solution is pretty stable. All of our products are freshly made. It is stable for at least one year after you receive the product.


    How should I use this product? 

    Use up to 1 ml per application. Use no more than once  a day. Each unit is 60 ml (2 oz), sufficient for a 2-month supply. The product comes with a calibrated dropper. 


    What is the difference between dutasteride and finasteride? 

    The structure of Dut and finasteride (Fin) are shown below. Both have similar structure to that of testosterone, the substrate of 5-alpha-reductase (5AR).  That is the exact reason why they can bind to the active site of 5AR and inhibit its activity. Both Dut and Fin are very good 5AR inhibitors (or DHT blocker). They tackle hair loss by inhibiting 5AR activity to reduce DHT level. 

    The difference between dut and fin are: (1) Dut is a stronger DHT blocker. Dut is a both type I and type II 5AR inhibitor, while Fin is a type II 5AR inhibitor only.  For type II 5AR, duta-steride is approximately three times more potent than finasteride.

    Dut has a much longer half life than fin in the human body (4-5 weeks vs 5-6 hours).

Game changer
I have been using this for a few months now and have noticed some major improvements in hair regrowth - I have been using it in conjunction with 15% minoxidil max solution- - I use the 15% minoxidil in the morning and the Duderma around 6.00pm - then 15% minoxidil at night- Unlike finasteride - the DuDerma blocks both of the reductase (1 and 2) enzymes that convert Testosterone to DHT which weakens and destroys the hair follicles- I honestly think the DuDerma could be a game changer regarding hair loss in men

Would love a version without PG
Many hair loss sufferers are allergic to propylene glycol, unfortunately so am I. I would love a version of this without PG.

Reply from Seller Thank you for your suggestion. We do have a version without PG now.

First product which has ever worked on me
This is the first product which has ever worked on me. I have used minoxidil and finasteride with no regrowth. I have only used this less than a month and I could definitely see new hair growth. Thank you minoxidilmax for making this product.

Reversed balding
I had a clear bald patch on the crown and receding at the front. I have used this for months and whilst it has not 100% covered up nor is it hair transplant thick I am no longer bald. I'd say my hair has gone back about fifteen years in time. Which at my age is about as good as you can expect. With Fint/Dutasteride it is best to think they will stop you going more bald rather than getting insane growth. Yes you can be lucky. And the earlier you tackle your hair loss the better.

Seems to work
As I was young and did not want to be bald, I had a hair transplant. At the beginning, everything worked out well. I used minoxidil regularly, but it had a little effect on hair loss. I found topical dutasteride when I was almost desperate about my progressive balding. So far, it seems to work, at least the progression of hair loss seems to have stopped. Good thing is that I have not noticed any side effects (for example, with finasteride pills had loss of libido). I am looking foward to long term results, as I have used it only for a couple of mounths.

Great seller and product
I used Essengen-6 Plus for a few years. The result is good but seems plateaued. I want to give dutasteride a try to boost my regrowth. I asked MinoxidilMax if they could offer topical solution. They were kind enough to make it and let me try it. I used this product for one week. It is too early to see any difference. The solution is odorless. It dries very quickly. I mixed it with Minoxidilmax PG Solvent to bring it to 0.1%. I used only 0.5 ml of the diluted solution. So it is about 0.5 mg a day.

Didn't work for me
Love this companies products and had high hopes for this product. Purchased 3 of these to ensure I gave it a proper chance but unfortunately my hair didn't respond.

Completely regrew my hairline
I have been using minoxidil and finasteride for +20 years and have kept my hair. However I sometimes experience periods of increased hair loss in the front. I wrote to Leslie from Minoxidil Max and she recommended DuDerma. Have been using it for app 4 months now and my hairline is perfect. This is truly the mixing link and a miracle product in hair regrowth.
Verified Buyer
I been using DuDerma for two and half months. I started out using 1ml at .05% two to three times a week to currently using 1ml at .1% every other day. I am am also using the Covet shampoo. I believe DuDerma is contributing to controlling heavy hair shedding but as of now I don't see any hair regrowth.
