Caffeine? Ive never heard of using that lolI think combinations are the best. Biotin by itself wont do much, if anything, I'm guessing. But a combination of biotin, nizoral and maybe something like caffeine on the scalp can trigger some regrowth.
Also i read that plucking hairs can help create new follicals. Debating on plucking regrowth wispy hairs.
Lol i wouldnt actually do it but its an interesting studyI call Complete BS. If you pluck a hair in a follicle that's dying, wouldn't you just expedite the balding process as a new miniaturized hair would grow to take its place (until ultimately a hair no longer grows?)
