Alopecia treatments


Propecia contains finasteride 1mg, which is a competitive and specific inhibitor of type II 5α-reductase. It inhibits a process responsible for miniaturisation of the scalp hair follicles, which can lead to reversal of the balding process


Regaine for Men Extra Strength Scalp Foam 5% w/w Minoxidil and Solution contain 5% of the active ingredient, minoxidil. Regaine for Women contains 2% minoxidil. The mechanism by which minoxidil stimulates hair growth is not fully understood, but it can reverse the hair-loss process of androgenetic alopecia by the following means: increasing the diameter of the hair shaft, stimulating anagen growth, prolonging the anagen phase, and stimulating anagen recovery from the telegon phase. A peripheral vasodilator, minoxidil enhances microcirculation to hair follicles. It also stimulates expression of vascular endothelial growth factor (VEGF), which is indicative of the high metabolic activity observed during the anagen phase
