Welcome To HealthacareMagic forum,
Nithya if your scalp does not show any scaling or excess peeling form a particular site ,then you won't be having any fungal infection
There are two other conditions which you might be having .Probably just a excessive dandruff
which is causing itching.And secondly ,if itching is very sever ,then you should rule out HEAD LICE .
For dandruff you can use a kecoconazole 2% shampoo twice a week along with topical steroid
For head lice
,you should use 1% permithrine solution as a shampoo for scalp.
would help you find a perfect solution for you.
Hope this answers your query ,if you have any further question ,you can write back to us.
