Finasteride 1mg is the active ingredient of the well-known hair loss treatment Propecia. It is now also available in a cheaper generic form, under the name Finasteride. Both Propecia and Finasteride are prescription only medicines, but are not currently available on the NHS for the treatment of hair loss. There is good clinical evidence for the effectiveness of Finasteride in the treatment of male pattern balding.

How does Finasteride 1mg work?

Finasteride works by combating the effects of DHT upon the hair follicles. In this sense, it is a “DHT blocker”, however it is not referred to by this name in the medical community. As a treatment for male pattern baldness, Finasteride is sold in the form of tablets (either as Propecia or as generic Finasteride). This treatment works better if used early in the natural history of hair loss development, and is much less effective when hair loss is well established.

One tablet must be taken every day for as long as you wish to combat hair loss and improvement is usually seen at 4-6 months. Finasteride cannot provide a permanent cure for hair loss, so if you stop taking it, your hair loss will resume. Any new hair that has grown will likely fall out after you have stopped taking Finasteride.

DHT stands for dihydrotestosterone, which is a form of testosterone. Male pattern hair loss is caused by a very sensitive reaction to DHT. Dihydrotestosterone halts nutrients from being absorbed by hair follicles, which causes them to shrink and eventually fall out. In these cases, Finasteride can be prescribed to act as a DHT blocker.

No, Finasteride is not suitable for women or children. If you are a woman experiencing hair loss, you may way to consider options such as Regaine for Women, which contains the active ingredient Minoxidil.
