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

     

TWO VERSIONS
  • 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 (with PG). ~15% people are allergic to PG with symptoms such as itching scalp and skin rashes. 

    This product is without any minoxidil or finasteride. It is a dutasteride only product. We have other products that have them together. 

MORE INFO
  • 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 dusolution, you will add 20 ml of DuDerma to 60 ml of PG Solvent/PG Free Solvent.

     

ABOUT DUTASTERIDE
  • 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).

FREQUENTLY ASKED QUESTIONS
  •

    How should I use this product? 

    All ingredients used in this product are medical grade. The product is for laboratory research only. You will decide how to use the product.  

     

    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).

Dutasteride
I have used it for almost 4 weeks. Since I started my scalp itching has been away. Unfortunately the hair loss is still falling, and I am afraid dutasteride is not getting through the skin. I have tried to use dermaroller 1.5 mm before the topic solution, but I have not obtained the desired effect. I will give it 2 more months before I have my final conclusion.

Best for controlling hair loss and possible hair re-growth
I have been using topical dut alongside oral dut 0.5 mg/ daily without any side effects. I had my hair transplant last year in November and started dut about 2 weeks after the transplant. I have experienced good result so far and expecting better in next few months to come. Soon i will add RU in my routine too. Minoxidilmax is really doing an wonderful job. Cheers from England.
