I was ready to give up on CG after a few weeks because my hair was just becoming less and less defined. It was stretching out and frizzing...just...bad. Then, I somehow came to the realization that I was over-conditioned. I too was terrified of ruining my hair with protein, but it's pretty much the only cure for too much moisture, so I did the gelatin PT too. Now I use protein every day and my hair is doing much better!!! I had reasonably healthy hair to begin with, so I think all the emphasis on moisture was just too much for my hair. I'm still trying to find a balance but so so happy I took the protein leap of faith lol!
I'm glad it's worked for you too! It's a great feeling
