- a hair follicle is an organ that produces hair.
- the growth cycle of the hair follicle is a growth phase (anagen), regression phase (cat agen), telogen force following the regression phase, and entering the growth phase after the rest phase.
- the growth phase is the period from the 1st to the 19th day after hair removal
- the regression phase is the period from the 20th to the 21st day.
- it is known that it enters a resting period 21 to 22 days after hair removal.
- new hair growth elongation
- hair follicle growth is activated in the skin, with the bottom reaching the lower part of the skin.
- the hair follicle is present in a small state in a shallow part of the skin.
