I have really thick, wavy 2C hair and my question is about my scalp, actually. I have a pretty dry scalp and my cosmetologist sister has told me it's because of all the parabens and sulfates in the products I use. Can you recommend something to help with the itch? I don't have flakes, though, just itch. I don't know if switching ALL of my products to P/S-Free is the answer or if just switching my actual styling product would suffice. Thanks for any help you can provide!
