Thinning Hair in Men
The problem of thinning hair is most common in men, with over 40% of men under the age of 35 experiencing some hair thinning. Men who suffer from hair loss typically start with a receding hairline and thinning at the crown. The hair loss gradually progresses to a bald spot at the crown and eventually complete baldness on the top of the scalp. It is now universally accepted that the most common cause of thinning hair in men is attributed to a chemical derived from testosterone called dyhydrotestosterone (DHT).
