Hello,
What you are having is male pattern baldness. Also called androgenic alopecia, it is a common form of hair loss and typically occurs in M shaped pattern.
Men who have this type of hair loss usually have inherited the trait. Other causes may be use of some drugs, infections and underlying disease, such as lupus or diabetes. A biopsy (taking a small sample of cells to examine under a microscope) of your scalp may be needed to establish the correct diagnosis.
Medicines which are useful are minoxidil and finasteride which you are already taking. Finally one can resort to hair transplantation also. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Please anyone suggest me for my problem.
