When deciding on what shampoo to use my suggestion is to decide on one and stay on what you've chose because from my experience mixing different shampoo may damage your hair. Here I posted the ones that helped me repair my damaged hair.
I have a lot of damaged hair and dry ends. I have volume but not shine these are the conditioners that helped me and maybe can help you also
Masks are the topic of the cake, they are needed for a little magic for the beauty, hope these masks can help you the same way they did to me.
Use oils only if you have dry hair and not oily
