This is something that I've wondered about. Is it known to what extent topical finasteride is absorbed directly through the skin and into the hair follicles? Could it be that its main mode of action is through being absorbed systemically in the first place and then making its way from the bloodstream to the hair follicles, rather than through being absorbed directly through the skin into the hair follicles? Anyone know of any research done on this?
This is obviously an important question, because if topical finasteride only works by means of systemic absorption, this defeats the entire purpose of using it as an alternative to oral finasteride in the first place.
