What are the 3 phases of hair growth?

At any given time, a random number of hairs will be in one of three stages of growth and shedding: anagen, catagen, and telogen.

What is the second stage of hair growth?

The second phase of your hair growth cycle is Catagen. This period is short, lasting only 2-3 weeks on average. In this transitional phase, hair stops growing and detaches itself from the blood supply and is then named a club hair.

What is the hair cycle?

Hair grows from the follicle, or root, underneath the skin. 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. Over time, the length of the anagen stage decreases.

What is the phase of hair growth?

The anagen phase is when your hair grows—your hair follicle forms a new hair shaft. Most (90%) of the hair on your scalp is in a growing phase that lasts from 2 to 6 years. The catagen phase follows the anagen stage. This is a 1- to 2-week transition stage between anagen and telogen.

Which is the first stage of hair growth?

These stages of hair growth have been studied in great depth to better understand how hair grows and what might be done to prevent or treat premature hair loss. The first three phases — anagen, catagen, and telogen — cover the growth and maturation of hair and the activity of the hair follicles that produce individual hairs.

When does the anagen phase of the hair cycle end?

What is the Catagen Phase? Following the Anagen Phase, your hair cycle enters a short transitional phase known as the Catagen Phase, which signals the end of active hair growth and cuts individual hairs off from the blood supply and from the cells that produce new hair. Approximately 3% of all hairs are in this stage at any time.

How long does it take for hair to grow on the scalp?

During this phase the hair grows about 1 cm every 28 days. Scalp hair stays in this active phase of growth for two to six years. Some people have difficulty growing their hair beyond a certain length because they have a short active phase of growth.

Which is the shedding phase of hair growth?

Some health experts consider the telogen phase the shedding phase, as well, but many scientists have divided this stage into two parts: the telogen and exogen stages. 4. Exogen: Shedding phase
