If I massage my head with garnier, it itches, if I use garnier for rinse out, it's fine. When I use Organix Acai Berry Avocado for co-washing, my head is much happier. I have been using Suave for the rinse out, which I know is backward compared to what most people do, but so far it works better that way for me. I have TONS of hair! I also try not to get any product directly on my scalp (obviously it touches my scalp, but I try not to push when I put the products in, if that makes sense). If all else fails, just do a regular shampoo here and there. Trial and error...but I'm learning a lot!
