Hi,
You had
alopecia areata ,which recovered and you got white hairs. This is totally normal.
The problem is your scalp itching..right ? And hair loss...
Your scalp is clean without rash and flakes..it means it is not scalp prurigo or seborrheic
dermatitis.
Then it is simple
pruritus of scalp. And may be due to stress, tension or some internal diseases like DM,
anaemia,renal or hepatic diseases,blood diseases and so on.
For perfect diagnosis, you
consult dermatologist. He will try to find out the cause by thorough history, clinical examination and blood investigations.
If there is cause, take treatment accordingly.
If no casuse is found, then it would be psychological.
Oral anxiolytic and antihistaminics will improve the condition.
I hope you got my answer.
Thanks.
Dr. Ilyas Patel MD
