Thanks for writing in.
There is nothing to be worried about.
It can be seborrheic dermatitis
You can use medicated shampoo like Salisia KT shampoo.
You can use Zydip C lotion once a day at scalp
Also you can take tablet Zyrtec
These will help a lot.
Visit a qualified dermatologist
or physician for proper diagnosis and treatment.
Hope this helps.
