I have been finding scabs on my scalp as well as it feeling itchy in those spots. Also my hair can't go without a shampoo for more than 24 hours or it will start to clump together in a greasy mess at the roots, however the ends of my hair seem rather dry. I've tried using tar shampoo and it got better initially but soon returned to its usual condition. I now use Head & Shoulders which seem to control the itch a bit better. I tried using my children's shampoos but they either don't do a good enough job of cleaning and leave my hair greasy, or they just make my scalp itch even more. Should I be trying another shampoo? Say one labelled specifically for oily hair perhaps? Or should I just go to the GP or a trichologist or even a dermatologist? Its really bothering me. I have some grey hairs, I haven't been dyeing my hair for the,past 3 years since this started, and just wish this would go away. .
