Hello,
The symptoms can be due to dandruff, seborrheic dermatitis or
lice. Eat a healthy diet. You can also take vit B6
and vit A
and E which are good for hair
and skin. Try medicated shampoos for dandruff. There are a number of over-the-counter shampoos available that can help. The most effective ingredients -- antimicrobials -- to look for are zinc pyridinethione, selenium sulfide, sulfur and ketoconazole (also available by prescription).
