Hair falls. Many white hair in my head.

You are suffering from androgenic alopecia which is also called as pattern baldness. The hairs start reducing in density at the crown (top) and also the hairline starts receeding  from the front. This is usually progressive throughout life unless treated. It is usually accompanied by severe dandruff which we call seborrhoea. The FDA approved treatment for this condition is the best. No oil or cream will magically work because the hairs are getting miniaturised  and eventually disappearing due to the hormonal effects of DHT on the hair roots. Please contact me with photos using online consult option for proper examination and treatment. Do not start treatment without consulting. I can give guidance and then you can continue treatment on your own.

Hi Thanks for your query. Hair in young men is usually attributed to hormones and genetics. Since we are unable to change your genetics, we can take steps to protect the hair you have and fight the effect of hormones and genetics. Options include using vitamins to balance your diet, such as a Hair/Nail/Skin vitamin. Topical medications such as minoxidil to increase blood flow to the hair follicle. Oral medication such as finasteride to block the effects of hormones on the hair follicle. You can consult on private chat with clinical photographs for personalised treatment
