Lash Hair Anatomy
As the client's natural lash grows (just like head hair grows), the extension grows with it and if too much time passes in-between appointments, the lash extensions may turn and poke the client in the eye.
THE LASH GROWTH CYCLE
First, the anagen phase is the growth phase of hair follicles. Often called “baby lashes”. This lasts about 30 days.
The second, catagen phase, is a transitional phase following the anagen phase. It concludes the active growth phase of the eyelash and releases it from the hair root. This phase lasts between approximately 2-4 weeks.
The third, telogen phase is the resting phase of the hair follicle. This ends the growth cycle the eyelash is pushed out by the new eyelash growth.
LASH HAIR ANATOMY
Lash hairs start growth down in the subcutaneous fat layer where they have a blood supply. There are multiple layers, like an onion, of a hair. Check out the illustrations below to understand the anatomy of a hair.
