So there are replacement hairs that grow right? But how do they grow so fast? or do they?? Do they catch up to the old hair length and how do they do this?? Thank you…
we mean the mechanics of hair growth….like if a hair falls out, and hair is falling out constantly, how does the new hair catch up with it in time…i mean it takes so long for the hair to grow…so how does it catch up with all the hair falling out….because it takes really long
