I am experiencing severe itching all over my scalp. I have been checked for lice (I have children in public school:o)) and ruled that out. I have had this for about 3 weeks, and it's driving me crazy. I have been using Nutrogena T-Gel shampoo for about a week, but it is not helping. The itching is so bad, that my husband says I scratch my head frantically all through the night. Fortunately, I am a very heavy sleeper so this does not bother me. There is no discoloration of the scalp. It is not flaky, however, I do think it feels like there is an almost sticky film on my hair after I wash it. I guess that could be the shampoo, though. Is there anything you can tell me about this? Do I need to see a doctor, and if so, do you recommend my family physician or a dermotologist? Thank you for your time. ~~~Melissa
