Hair cycle




The stages of hair growth help better understand how hair grows and what might be done to prevent or treat premature hair loss.

In fact, 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. During the final phase, exogen, some hair sheds, but usually, new hairs are getting ready to take their place.

Each phase has its own timeline, which can be affected by age, nutrition, and overall health. Therefore, a healthy lifestyle, limiting stress, proper diet, and gentle hair care can help promote healthy hair growth for a long time.

If you believe that you’re losing your hair at a faster rate than you’re used to, book a free consultation at Nar London. An underlying condition that is disrupting the cycle of hair growth may be to blame, and treating it promptly may help slow hair loss and preserve the healthy hair you have left. Moreover, it is also possible to stimulate the growth of dormant hair follicles with non-invasive hair loss treatments.

1. Anagen: Growing phase 

First, the stages of hair growth begin with the anagen phase and this is the longest phase, lasting about 2 to 6 years.

During the anagen phase, your hair follicles are pushing out hairs that will continue to grow  (about half an inch each month) until they are cut or reach the end of their lifespan and simply fall out.

At any time, about 85/90% of the hair follicles on your scalp are in the anagen phase.

2. Catagen: Transition phase

Secondly, the catagen phase starts when the anagen phase ends, and tends to last about 10 days or so.

During this cycle, hair follicles shrink and hair growth slows. The hair also separates from the bottom of the hair follicle, yet remains in place during its final days of growing.

Only about 5 percent of the hair follicles on your scalp are in the catagen phase at any given time.

3. Telogen: Resting phase 

Thirdly, the telogen phase typically lasts around 3 months. It is estimated that 10 to 15 percent of your hair follicles are in this phase.

This phase also called “resting” because the hairs don’t grow during the telogen phase, but they don’t usually fall out either. The telogen phase is also when new hairs start to form in follicles that have just released hairs during the catagen phase.

Many 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 

Finally, the exogen phase is essentially a “continuity” of the telogen stage of hair growth. During the exogen phase, hair is shed but losing 50 to 100 hairs per day is normal.

This cycle can last about 2 to 5 months, new hair follicles are growing, and “older” hairs fall away.
