I need to find a good protein treatment, myself. I used to use Komaza and haven't found a replacement. This week, I'm going to try using gelatin and see what my hair feels like.
That said, since the beginning of the year I've been adding silk amino acids plus a combination of hydrolyzed oat protein, plant keratin, and hydrolyzed baobab protein to my ayurvedic mixes. At first I thought the same as you, that my hair would snap, but my hair loves it. I use them every week. If you look through this thread you can see which hebs I used along with which proteins.
