Itchy scalp

I have a very itchy scalp not all over but in patches.  Ive tried every scalp treatment shampoos etc, my doctor gave me zamiol which hasn't worked.  I haven't got a dry scalp, no dandruff, redness or rash.  I even tried nizoral fungal shampoo with no luck.  At moment using a coal tar based shampoo but with no results.  Could this be caused by an internal problem and not actually the scalp it self.  I'm 45 and poss pre menapausal, could the hormone changes be responsible?

Hello,
There are many causes of itchy scalp apart from dandruff. These include seborrheic dermatitis, dye allergy. Reaction to perm chemicals, fungal infection or neurodermatitis. Neurodermatitis develops when nerve endings in the skin become irritated, triggering a severe itch-scratch-itch cycle. Common causes of nerve irritation include an insect bite and emotional stress. I suggest you to get an examination done from a dermatologist.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
