Similar to other body hair, eyelashes undergo a three-phase growth cycle: anagen (growth); catagen (transitional); and telogen (sleeping or relaxing). The growth phase duration dictates the length of time that eyelashes will develop.
The growth phase of eyelashes typically lasts between 30 and 45 days. The eyelash then enters the catagen and telogen phases, during which the previous lash is shed to make way for the subsequent one. The length and growth rate of eyelashes may be impacted by distinct individual factors, including genetics and general health. The rate of hair growth, including that of eyelashes, may decelerate with age. Nevertheless, there is no universally recognized age at which eyelash growth ceases. It differs among individuals.
Generally speaking, eyelash growth can persist into old age; however, it may decelerate proportionally. It is recommended that individuals who observe substantial alterations in their eyelash growth or have any concerns approach a healthcare professional or dermatologist for individualized evaluation and guidance.
