I am all for anything that makes the user feel that it's working, but I did stumble upon this blog post by the Beauty Brains a few days ago and thought it was an interesting look at amino acids:

Back on Cones,so now my routine is,wash with Deva No-Poo every other day or so. Occasionally use 365 sulfate free,maybe use low sulfate shampoo mixed with conditioner once every two weeks are longer. I condition with Aussie Moist or HEHH. I style with a little GF TN,and finish up with tons of GN Pure Clean Smoothing Cream. No frizz...slippy, happy hair.
