Eyelashes stop growing once they reach their maximum length during the Anagen phase of their growth cycle.
Eyelashes, like other hair on your body, go through a growth cycle. This cycle has three main phases: Anagen (growth), Catagen (transition), and Telogen (resting/shedding).
- Anagen Phase: This is the active growth phase. According to provided context, eyelashes grow actively for about 30-45 days. Approximately 40% of your eyelashes are in this phase at any given time. This phase determines the final length of the lash; once a lash reaches its maximum length, growth stops.
- Catagen Phase: This is a short transition phase where growth ceases, and the hair follicle shrinks.
- Telogen Phase: This is the resting phase, lasting several months, before the eyelash eventually sheds and a new lash begins to grow.
| Phase | Description | Duration |
|---|---|---|
| Anagen | Active growth; determines maximum length. Growth stops at max length. | 30-45 days |
| Catagen | Transition phase where growth stops and the follicle shrinks. | Short |
| Telogen | Resting phase before shedding. | Several months |
The length of the Anagen phase varies between individuals and can be influenced by several factors, but the key reason eyelashes stop growing is that the Anagen phase ends after a predetermined length is achieved.
