Hi, The hair fall can be due to various reasons like dandruff, use of hard water for shampooing, male pattern baldness, underlying medical conditions etc. For dandruff keep your scalp clean. Avoid excessive use of oil. You can use an antidandruff shampoo like scalpe twice a week. For a more specific and definitive treatment you need to visit a dermatologist. As far as excessive sweating is concerned various treatments like iontophoresis, botox etc are available which can also be addressed during your consultation Dr Rashmi Soni Lohiya (MD, DNB, DDV )
