How Much Do You Know About Hair Follicles
Scientific Principles: The Growth Pattern of Hair Follicles
You may not know that the hair on our bodies does not grow all at once. Each hair follicle has its own schedule, like a small factory, with working and resting times.
Human hair cycles according to its growth cycle. Each hair follicle goes through three stages: growth phase, regression phase, and resting phase.
The growth period usually lasts for 2-6 years, during which the hair follicles are active and produce visible hair. The degenerative period lasts about 2-3 weeks, and the hair follicles begin to shrink. The resting period lasts for several months, during which hair stops growing and eventually falls off.
At any given time, only about 20% of hair follicles are in the growth phase. This means that in a single treatment, IPL can only act on these active hair follicles.
