Thinning hair and baldness in back area.

You may be 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 refeeding  from the front. This is usually progressive throughout life unless treated. This may also be accompanied by severe dandruff. The treatment for this condition is a lotion and tablets. There is no other alternative. No oil or cream will magically work because the hairs are getting miniaturised  and eventually disappearing due to the hormonal effects on the hair roots. Along with this, you can also consider platelet rich plasma therapy for faster results. Please contact me with photos using online consult option for proper examination and treatment. Do not start treatment without consulting..

Yes u can take Biotin but preferably take it in tablet form to have better absorption and efficacy. in Addition u will also have to maintain with dietary supplementation of biotin. Biotin does work for the hair but u have to also know the exact cause of ur hair loss else this will be a progressive condition. Consult a Dermatologist for the same to know the exact cause of ur hair loss to get better effect and long term relief.
