To begin with you'll have to take care of your scalp and get rid of your dandruff problem. A valuable prescription for removal of dandruff is the use of green gram powder. The hair should be washed twice a week with two tablespoons of this powder mixed with half a cup of curd.

Anti-fungal/anti-dandruff shampoos containing ketoconazole have been shown to be effective in the treatment of dandruff. A therapeutic hot oil massage helps to nourish dry skin follicle and stimulate production of sebum. A mixture of egg yolk and sour yoghurt also nourishes hair strands and stimulates the oil balance of the scalp. Apply the mixture on the scalp for half-an-hour. Then rinse and shampoo. This should help reduce hair fall too.
