Ive wondered if peppermint oil might actually slow keratinocyte cell division or actually harm hair or slow cell division in one of its component parts. Alpecin's reserch showed that caffeine alone counteracted the slowing of hair growth of testosterone in their experiments, but alpecin (which contains alot of menthol to slow the metabolization of caffeine) seemed to see keratinocyte activity remain halfway between the control group and the testosterone group according to their own research.
I do know one thing, it so drammatically inhibited hairgrowth on one side of my chin, it made me wonder if what Bryan suggested (that there may be something in peppermint that is hard on hair) could be right. It definitely is what I recommend for men whose beards are too thick or grow to fast and want to lessen the five o'clock shadow. I think it would be a great anti-hirsutism treatment that would be very cheap.
There are a few other potential topical anti-androgens (green tea extract which Im putting on my face right now----and seem to already be getting a positive result from to be honest...........we will see), clove, arnica, rose hips, topical curcumoids, licorice. I feel optimistic that one of these is going to be a cheap winning anti-androgen that we can make very cheaply at home. As Ive said before, I doubt any of us is going to find a hypertrichotic that can outdo prox-n or minoxidil as growth stimulants are likely to be complex things, but we might be able to trip up on a natural anti-androgen that downregulates or blocks the human androgen receptor (or even inhibit alpha five reducase----licorice does both) that can be soluble with a penetrating agent (alcohol) and water so we can make it ourselves.
I hope green tea extract is it. Its soluble with water and alcohol, its cheap and easily obtainable. I bought mine from Nature's Way in capsules, and I think Bryan mentioned he bought his from Beyond-a-century.com and its guarnanteed to have 45 percent or so ECGC content. The side of my face Ive been spraying the green tea extract/alcohol/water mix sure is dry vs. the other side...................and the whiskers do seem be lagging a tad behind the growth of the whiskers on the other side. But its very early yet. Gimme a month and I ought to be able to tell you what I see on close inspection. Based on the flank organ results Liang and Lao had, if we can get ECGC to the correct area and it not be metabolized too quickly, it ought to be a very effective antiandrogen. Im crossing my fingers.
