The condition can be demodex follicullitis,pediculosis capitis
,seborrheic dermatitis,contact dermatitis
Permethrin 5%cream application can help in pediculosis capitis.
A visit to dermatologist
would be needed for proper diagnosis and treatment.
Till the time you can take tab.Zyrtec twice daily for itching and apply good quality moisturizer lotion over the area.
Hope this helps.
