Hair growth speed linked to the hair cycle
- First, the anagen phase, which is the growth phase of the hair and which lasts between 3 and 6 years on average.
- Next, the catagen or transition phase, which lasts for less than a month. During this phase, hair growth slows down.
- Finally, the telogen phase, which ends the cycle and corresponds to the hair loss period. It lasts for approximately 3 months.
Each hair follows its own cycle, not synchronized with the cycles of the other hairs. So it is therefore normal to find that about a hundred hairs have fallen out every day. When a hair reaches the end of its life cycle, it naturally detaches itself from the hair follicle and falls out. A new bulb develops in its place and a new hair begins its life cycle. There is little chance that your scalp becomes bald.
So how long does it take to grow out bangs or hair that was cut too short? Too long, is what we usually think. Hair growth rate per month varies from one person to another, but the experts agree that hair grows an average of 1 cm every 30 days. This growth is faster in Asian hair, which is thick and strong. It is considerably slower in coily hair, which is fragile and brittle.
