Hi sir i have a hair fall problem give me some medication or tell me about perfect diet for hair care?

Depends on cause...: One's primary care doctor can check for medical causes. If none are found, then one can see a dermatologist, especially one specializing in hair restoration (some treatments: minoxidil, finasteride, hair transplants, ...). Medical causes may include: hormonal problems (low thyroid), seborrhea, alopecia areata, stressful illness. Other causes: genetic male/female pattern baldness, telogen effluvium.

Hair care: Avoid over-washing your hair. Don't apply shampoo directly to the roots. Distribute conditioner evenly through your hair. Avoid using hot tools (hair dryer, flat iron) every day. Use a deep conditioning treatment once a week. Do not comb or twist wet hair. Massage in warm olive oil or coconut oil and leave for 30-40 minutes before washing. Always use lukewarm (not hot) to wash your hair.
