Each natural lash, just like human hair, is composed of 10% water and 90% proteins including keratin and melanin that are produced by hair follicles. Hair follicles are made of living cells that are nourished directly at their base from blood vessels.
There are usually 90 to 150 lashes on the upper eyelid, while the bottom may have up to 80 lashes. Eyelashes grow at a rate of approximately 0.15 mm per day and can take about two months to regenerate when pulled out. Did you know that lashes are the most pigmented out of all human hairs - they don’t usually turn grey! As we age, the lash cycle can become shorter. The follicle stops producing strong, long lashes, in turn creating thinner and shorter lashes.
EYELASH GROWTH CYCLE - 3 PHASES
ANAGEN: Also known as the growth phase. The natural lash is actively growing. This phase usually lasts between 30-45 days.
CATAGEN: Also known as the transition phase. This phase usually lasts 2-3 weeks.
The lash follicle stops producing hair, and the hair follicle moves up towards the skin's surface. If a lash falls out during this phase, it will not grow back until the phase has finished.
TELOGEN: Also known as resting phase. This phase lasts 3-4 months. As new hair grows in the follicle, the old hair falls out. The old hair is replaced by the new growing hair, and the cycle starts over with the anagen phase.
