Brief Answer: details below Detailed Answer: Hi XXXXXXX Thanks for writing to us. Your brother could be having seborrheic dermatitis which is leading to hair fall. To treat the same, he should Use a ketoconazole based shampoo every alternate days(scalpe/nizoral/ keraglow ad/danclear/dandrop etc). Ask him to apply the shampoo over scalp atleast for five to ten minutes and then should rinse with water Use a steroid salicylic acid lotion in night( diprovate s/ topisal etc) Once dandruff is gone, he should just continue with medicated antidandruff shampoo once in a week. Rest of the days, he might use his normal shampoo to wash hair. Also oil aggravates dandruff, so once in a week oiling is enough to counter dryness. He may also try mild shampoos like triclenz or X gain to keep his hair healthy and soft. Water used for bathing or washing should neither be too cold or too hot. XXXXXXX warm water is good for bathing. Once dandruff will completely clear off, hair fall will stop and hair would grow back. Sometimes we also prescribe 5% minoxidil to aid hair regrowth. Hope this answered your query. Take care
