Hair loss is something that will affect almost all men and many women throughout their lifetime. Hair loss can be the natural result of ageing, a sign of an underlying medical condition, caused by hereditary pattern hair loss, severe stress or an emotional shock, or from some medical treatments.

The hair growth cycle
 
Your hair follows a specific cycle of growth with three distinct phases that all occur randomly and can be happening simultaneously for different hairs on your head: the anagen, catagen and telogen phases. Each phase has certain characteristics that will determine the length of individual hairs.
 
The anagen phase is the active phase of the hair growth cycle. Most of the hair on your scalp will be in this phase. During the anagen phase, hair grows at a rate of about 1cm every 30 days. The hair on your scalp will stay in this active phase for between 2 and 6 years.
 
The catagen phase is the transitional stage that lasts for about 2-3 weeks. About 3% of the hair on your scalp is in this phase at any one time.
 
The telogen phase is the resting phase and lasts for about 100 days for scalp hair and longer for hairs on the rest of your body. About 6-8% of the hairs on your head will be in this phase.
 
Because each of these phases can happen simultaneously, it means that one set of hairs could be in the anagen phase, whilst another set of hairs on the other side of the scalp are in the catagen or telogen phase and growing at a completely different rate.
