Caffeine cures baldness

[Lorsss]

dermatology researchers have proved caffeine reduces hair loss "in vitro".
however it's very hard to cure baldness with caffeine: if you take caffeine pills, you need a 4 grams dose to let caffeine reach hair follicles, this dose is equivalent to 60 coffees or 12 caffeine pills.
also curing baldness topically is hard because caffeine doesn't penetrate the skin easily.
maybe caffeine injection could treat baldness in the future?
I don't know, but if continue losing my hair despite the minoxidil, I'm going to eat 12 caffeine pills a day.

if researches had seen results with topic treatment, caffeine would have already replaced minoxidil

No.
Caffeine can't be patented like minoxidil or finasteride. All natural products cant.
If there are no profits behind something then why spend million on research?
