Difference Between Dry And Damaged Hair Hair Products For Dry, Brittle, Damaged Hair?

Hair products for dry, brittle, damaged hair? - difference between dry and damaged hair

I do not need to well-known brands. Like gasoline, deep conditioning cream, etc. I will choose the best brand for me, but I did not really know the difference between wax and gasoline or something. I only know that they are products for hair and supposedly good for your hair.

I used to have healthy hair really quite simple, but I have colored and permed and is now a disaster. I judge her hair every day (recently) and I want is something that the contribution to return to normalcy. I already use gas dryer ... What should I use?
