Hi there, I'm sorry about what you are going through. I have gone through something similar for the last number of years. I would suggest researching scalp dysesthesia. I haven't found anything that consistently helps but am careful with what product I use on my scalp. Sometimes I think it helps and sometimes I don't. I tend to think that for me chronic telogen effluvium is associated with it. The condition is essentially hypersensitive nerve endings in the scalp. Donovan Hair Clinic online has some good articles on it as well as some other websites. I'm surprised that your dermatologist didn't mention this condition to you as it is characterized by abnormal sensations of the scalp (itching, burning, crawling, etc...) with no real scalp pathological conditions. I don't wish to go on gabapentin, pregabalin or amitriptyline which can sometimes help but that is me. I try lots of natural supplements and have currently added N-acetyl cysteine and R-ALA to see if it may make a difference. Good luck!
