Hello,
Thanks for writing here.
Dandruff is a
fungal infection occuring at teen age.At times it can be severe.You need a good antifungal shampoo like nizoral.Use it twice weekly.You can also apply antiboitic cream like
clindamycin over the affected area.For sensitive skin use a mild cleanser like
cetaphil.Avoid sun exposure. Consulting a
dermatologist will be better option.
Hope this will help you.Take care.
