How effective is finasteride?Updated 3 days ago

Finasteride is effective in reducing the amount of DHT in the scalp and has shown to be effective in 9/10 men. Finasteride slows or even reverses the miniaturisation process and thus allows hair follicles and cycles to normalise to achieve a thicker & fuller head of hair (1,2).
