I have itchy scalp, and bumps that are like a sore; very small. I ve had this problem for over a year. It started with scaly patches like cradle cap . The scabs,when I take them off, look like they could be a parasite. I have shampooed my hair daily for about 6 months with Mustela shampoo. It helps control the itching, but I continue to have the bumps, scabs, itching, etc. what do you recommend???????
