Edited for your enjoyment:
Been on snake oil for about a year and a half and have not seen even the smallest amount of regrowth.
But my armpit hair only started visibly growing after trying out the natural techniques to thicken it at www.Iwantlongarmpithair.com
There is also a cheap and effective way to twist and braid it to impress your loved ones!
I would highly recommend it to anyone who is suffering hairless armpits!
