Male-pattern baldness is the most common type of hair loss, affecting 6.5 million men in the UK.
It generally starts with a little thinning of the hair, followed by wider hair loss, allowing more of the scalp to become visible.
For a few men, this process starts as early as the late teens. By the age of 60, most men have some degree of hair loss.
Some men aren’t troubled by this at all. Others, however, suffer great emotional distress associated with a lack of self-esteem and, in some cases, depression.
