Clinical studies reveal that when you increase your intake of zinc, it banishes dandruff effectively. Nuts and seeds are rich in zinc, so load up on them. Zinc monitors levels of androgens in the body; abnormal levels of androgens are known to trigger dandruff and poor hair growth. Confer with your doctor and get a list of zinc rich foods and consider starting a zinc supplement as well. What’s more, trichologists also recommend hair care products that have zinc. A zinc formulation shampoo ensures that the scalp stays healthy, staves off dandruff and kills microbes too.
