I have a sensitive scalp & seem to react to products & face creams. I am currently using Pureology Hydrate but I think they must have changed the formula as I am reacting to it now. I definitely need a sulphate free shampoo & no slicones if possible. I have fine, naturally curly hair but it's very thin as I lost a lot of my hair after I had my girls. & it's never been the same since., I'm wondering if the Discipline Range would be any good or any other range anyone can recommend. I am in Australia but can get most professional hair care ranges or can order online.
