Thanks for your query.
It would have been better to advice after knowing your age and sex. Assuming that you are male and having androgenic alopecia
I would advice you to use topical minoxidil
over the scalp where hair fall is occuring.
Keep the scalp clean . Use ketoconazole
or selenium sulfide
sampoo for dandruff.
Have a healthy diet and plenty of fluids.
Keep your life stressfree.
Any systemic disease if present should be treated.
Hope this helps.
