Ill be bald in two weeks if this don't stop.

Have you seen a doctor about this and described all your symptoms?

Oh yes also have red scalp

I wonder if this is an allergy or caused by a food you are eating or shampoo you are using. The doctor gave no help?

Have you been to a dermatologist?

Do any of these fit your situation?
I agree about seeing a dermatologist specifically.
