I have colour treated hair and used a Keratin treatment. It dried out my hair. Advice?
I though that Keratin was supposed to make dyed hair stronger but it did the opposite and now my hair is breaking. Where did I go wrong?
If you recently color treated your hair immediately followed by the keratin. Treatment there's a high risk of damage because it's going through two extreme processes close in time healing time. I suggest using a restorative strengthening deep conditioner like Shea moisture Jamaican black castor oil masque.
