Just a quick note to say hi!
Dont give up I have the same problem. But in my case they bite my head until it is raw. As I am writing this i have a towel covering my head. I have read the comments and I believe it is a ph problem and I am going to try and correct mine as I know I am acidic. I also have Hypothyroidism. Dont let the doctors ingnorance upset you for a minute. Have you tried to balance your ph?
