Recently, I bleached my hair from natural level (5) to platinum blonde. I have very oily scalp but after bleaching my hair became totally dry. After 2 weeks my scalp returned to normal (it's oily again) but my hair is still dry. I use Kerastase shampoo (the black one for men) and once a week I use a silver mask. What I want to ask if I should use conditioner on my short hair in order to condition my dry hair. I tried to use 2 times conditioner (just a little bit on the ends) and what I got was oily scalp and flat hair (my hair is already flat and thin). Thanks a lot.
