Endomotor Hair Loss Stages in Men

Hair Loss in Males

The most common cause for hair loss in men is androgenetic alopecia or male pattern baldness. There is recession of frontal hairline and thinning of hair in the top of scalp. It is usually associated with family history of baldness.
It is slowly progressive noticed at late 20’s or early 30’s. But, in recent times this pattern has been noticed at an earlier age as well. There is no underlying hormonal abnormality,any dietary deficiency or other correctable causes which can stop progression. There are other causes of hair loss mentioned here.
Medical treatment in the form of minoxidil lotion and finasteride can halt the progression of baldness. Effects last for as long as the treatment is taken.
Hair transplantation can restore hair in the area of hair loss though the progression of hair loss is unaffected by this treatment.

Hamilton Norwood Classification for Males

This is the most popular and the most widely used classification for male baldness. Dr. Arul Norwood published this classification in 1975. This classification entails two major patterns and also several less common ones. There are two main areas of hair loss: bitemporal recession and thinning over the crown. Hair loss in these two areas increase as baldness progresses leading to coalescence until front, top and crown are entirely bald.
