What are the stages of hair growth?

​

Hair growth occurs in three distinct stages: anagen, catagen, and telogen.

​

1. Anagen phase: This is the active growth phase where hair follicles produce new hair cells. Hair grows about 1 cm every 28 days during this stage. This phase lasts anywhere from 2 to 7 years, depending on the individual.

2. Catagen phase: This is a transitional phase where hair growth slows down and hair follicles begin to shrink. This phase lasts for about 2 to 3 weeks.

3. Telogen phase: This is the resting phase where hair follicles are at rest and no new hair growth occurs. During this phase, the hair remains in the follicle until it is eventually shed. This phase lasts for about 3 to 4 months.

​

After the telogen phase, the hair follicle returns to the anagen phase and begins producing new hair cells, starting the cycle all over again.

​

More about the Anagen, Catagen and Telogen Phases:

​

Anagen

The anagen phase is the active growth phase of hair follicles. During this phase, hair follicles produce new hair cells, which eventually grow into a full hair shaft. The duration of the anagen phase varies depending on the location of the hair on the body and the individual's genetics.

​

On the scalp, the anagen phase can last anywhere from 2 to 7 years, with an average duration of about 3 years. During this time, hair grows about 1 cm every 28 days, resulting in a potential length of up to 70 cm. However, the maximum length that hair can reach is also influenced by factors such as hair care practices, age, and overall health.

 

The anagen phase is essential for maintaining healthy hair growth, and any disruptions to this phase can result in hair loss or thinning. Some factors that can affect the anagen phase include hormonal imbalances, genetics, medications, stress, and nutritional deficiencies.

 

Catagen

The catagen phase is a transitional phase of the hair growth cycle that follows the anagen phase. During this stage, hair growth slows down, and the hair follicle begins to shrink. The catagen phase lasts for about 2 to 3 weeks and is considered a brief phase in the hair growth cycle.

​

During the catagen phase, the hair follicle detaches from the blood supply, and the lower part of the hair follicle shrinks. The hair shaft becomes narrower, and the hair stops growing. The hair bulb, which is the part of the hair follicle that nourishes the hair, also stops dividing during this phase.

​

Telogen

The telogen phase is the resting phase of the hair growth cycle. During this phase, the hair follicle is at rest, and no new hair growth occurs. The telogen phase lasts for about 3 to 4 months and is considered a relatively long phase in the hair growth cycle.

​

During the telogen phase, the hair follicle is dormant and disconnected from the blood supply. The hair shaft is fully formed and anchored in the scalp, but it is not growing. The hair bulb is also inactive and does not divide during this phase.

​

After the telogen phase, the hair follicle enters the anagen phase again, and the cycle starts anew. The old hair shaft is shed, and a new hair shaft begins to grow from the same follicle. It is normal to shed up to 100 hairs per day during the telogen phase.

​

Various factors can affect the telogen phase, including stress, hormonal imbalances, medications, nutritional deficiencies, and age. If the hair follicles remain in the telogen phase for an extended period or if an increased number of hair follicles enter the telogen phase at the same time, it can result in hair loss or thinning.
