* Anagen (growth phase): This phase lasts about 4 to 10 weeks. During this time, the eyelash actively grows.
* Catagen (transition phase): This is a short phase, lasting about 2 to 3 weeks, where the eyelash follicle shrinks and detaches from the blood supply. Growth stops.
* Telogen (resting phase): This is the longest phase, lasting around 90 days. During this time, the eyelash rests, and eventually, it falls out to make way for a new eyelash to grow.
How Much They Grow:
* Length: Eyelashes typically grow to be around 10 millimeters (0.4 inches) to 12 millimeters (0.5 inches) long. The upper eyelashes are usually longer than the lower ones.
* Growth Rate: While individual eyelashes may have different growth rates during their anagen phase, an estimated average growth rate for hair in general is about 0.1 to 0.16 millimeters per day (approximately 0.004 to 0.006 inches per day).
Important Considerations:
* Individual Variation: Eyelash length and growth rate can vary significantly from person to person due to genetics, age, and overall health.
* Slow Growth: Compared to scalp hair, eyelashes have a much slower growth rate and a shorter growth cycle, which is why they don't grow very long.
* Damage and Loss: Eyelashes can be damaged or fall out due to rubbing, pulling, improper makeup removal, certain medical conditions, or medications.
