Hair grows from the follicle, or root, underneath the skin. The hair is ‘fed’ by blood vessels at the base of the follicle, which gives it the nourishment it needs to grow. Between starting to grow and falling out years later, each hair passes through four stages: anagen, catagen, telogen and exogen. Every hair is at a different stage of the growth cycle.
Anagen (Growing Phase)
Anagen lasts about two to seven years and determines the length of our hair.
During this phase the hair grows about half an inch per month, making it 6 inches per year.
Some people have difficulty growing their hair beyond a certain length because they have a short active phase of growth while people with very long hair have a long active phase of growth.
Catagen (Transition Phase)
Telogen (Resting Phase)
This is part of the resting phase where the old hair sheds and a new hair continues to grow.
Approximately 50 to 150 hairs can fall out daily, this is considered to be normal hair shedding.
