Hair fall of 50-100 hairs/day is normal.
If your hair is getting thin and your hairline is receding , it is most likely Male Pattern Hair Loss (aka Androgenetic Alopecia). It is the most common form of hair loss in men. Please refer to the attached chart for classification of the stages of this pattern of hair loss.
Treatments can be classified into surgical vs non-surgical.
The only surgical option is Hair Transplant , which involves extracting hair follicles from the back of the head to be implanted on the front balding areas . It is the ONLY WAY to regrow new hair on scalp that has totally lost the follicle unit.
Non-surgical options are mainly Propecia tablets and Minoxidil 5% spray .
Before you start on any treatment , please visit a doctor who has a keen knowledge and interest in hair loss for a detailed consultation.
