I haven't had that issue with the pantene so far, I use the shampoo that is the two in one, shampoo and conditioner, plus I use the conditioner for the same one. Oh and like I said I use a hot oil treatment once a week. And I have color treated hair. But I don't use cheap dye, I use Goldwell Topchick. Good luck finding an affordable salon that uses it though. I'm lucky enough to know how to mix dyes and know how to dye hair, so I order it off a salon supply site and do it myself. When my hair was pink (yes I had pink hair) I did it myself too. I never heard of fo-ti but will look into it, the hair and nail vitamins I take have biotin in it, and plus I take collagen tablets.
