Thank you so much for the great advice. I will try it and see how it goes.
Hello,
It can be due to dandruff which can be due to internal or external causes.
Dandruff can cause either an overly dry scalp with itchy white flakes that may be waxy or greasy, or it can manifest as an oily scalp with scales.
He should eat a healthy diet. He 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). If his hair is colored, don't use products with selenium sulfide or sulfur.
If the symptoms persist please consult a trichologist for the confirmatory diagnosis and treatment.
Hope it helps.Take care and regards.
