Treatment to hair fall?

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.

Depends on cause: Do you mean hair loss? Using rogaine (minoxidil) or Propecia (finasteride) can help slow down or reverse male pattern hair loss. Taking vitamins and supplements may help with hair health if nutritionally deficient. If there is an underlying medical condition causing hair loss, then finding and treating the cause (ie: anemia, thyroid disease) may help.
