I seem to be really itchy lately but my head and scalp is the worst... I don't have dandruff, but all this scratching is so unnattractive and making my hair greasy eventually... I wash it every 2 days.
Try Polytar shampoo. It does smell a bit strong while you are shampooing it in, but that goes away and most people have no problems with how it smells. It is very effective though! Good luck!
