Thin Jim said:Guys I have never found an answer to this question. Maybe one of the experts know like Bryan or maybe i'm just a retard. Has it been determined the actual Radius that minoxidil absorbs under the scalp. Reason being is that at the moment I am making an effort to make sure all of my scalp is directly in contact with the minoxidil. However I have read for example on Dr Lees site that the minoxidil spreads underneath the scalp once absorbed. Directions from his site are to part hair in 3 places and apply, but is this going to affect the whole scalp or only the area in which it is applied.
The skin is a reservoir for topical drugs. Repeated applications accumulate and are released over several days (highly lipophilic drugs can persist for weeks). It's not worth worrying about saturating every follicle during every application. If you don't hit it this time, you'll hit the next, or the next...
As minoxidil does not appear to protect the follicles from damage, there's even less reason to be concerned about insufficient coverage. Topical antiandrogens warrant a bit more attention in that respect.
