No use...You are suffering from seborrheic dermatitis causing dandruff and hair fall.. Medicine available for good improvement......As the treatment varies depending on the severity... Send photos of the affected area, by direct online consultation 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 contact me with photos using online consult option for proper examination and treatment.

Kindly consult online to find an solution.. Meer applying castor oil or taking biotin tablets will not help.. we need to find a cause of your hair loss nd treat accordingly

Please don't use any oil if u have dandruff issue , biotin is not the only things which prevents hairball my advice would be see a dermatologist for the same.
