Ive been using Polytar shampoo for a long time but it makes my hair greasy! I wash my hair with it every 2 days because by the 2nd day its become very greasy. I dont use any hair products btw. So Im washing my hair with it 3 times a week and its medicated. My hairdresser explained to me that I should ditch it and use a shampoo for normal hair. Can anyone recommend to me a decent shampoo that doesnt produce grease or dry the scalp producing dandruff?
