Hairfall is of several types. For example, male hormone related, related to any sudden illness, or related to other medical conditions. Treatment depends on the condition causing it. Your problem looks like that of androgenetic alopecia related to male sex hormones. It need not be a genetic condition. Take the help of a dermatologist. Your condition can be managed well by a dermatologist

Undergo PRP therapy. Few creams also available.... Send photos of the affected area for accurate diagnosis and treatment..

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 call me or  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.
