Aminos are supposed to help the hair grow faster, especially cysteine. I've been taking Puritans Pride Amino 1500 (which contains both proteins), along with PP Biotin and B complex. I have noticed a lot of new growth, and in the 7 weeks since my last relaxer I have 3/4 to 1 inch of new growth. I'm going to see how the hair grows in the weeks after my next touch up, which will be next week. If indeed the hair is growing faster, it's probably the combination of the stuff I'm taking.
Ive been taken them for awhile now (about 2 months) and i was actually thinking im gona stop cause they arent making a difference to me - so ill cut them out and add Protein Shakes.
