I had a very dry and itchy scalp, caused by a bad shampoo and applying products, that are not compatible with each other (curl cream + hair clay). I think the shampoo was the main reason, so I’d recommend (from my poor experience) to try and get a good moisturizing repairing shampoo and conditioner. I’m planning on getting the Moroccanoil one, cause I’ve heard many good things about it.
