Eyelashes typically take between 6 weeks and 3 months to grow back fully, depending on the cause of loss and the health of the hair follicles
. The natural eyelash growth cycle consists of three phases:
- Anagen (growth phase): Lasts about 30 to 45 days, during which lashes actively grow at about 0.12 to 0.14 millimeters per day
- Catagen (transition phase): Lasts 2 to 3 weeks, where growth stops and the follicle shrinks
- Telogen (resting phase): Lasts about 30 to 45 days or longer, during which lashes shed and new ones begin to grow
Since not all lashes are in the same phase simultaneously, eyelash shedding and regrowth is a gradual process, so you rarely lose all lashes at once
. Factors influencing regrowth time include:
- Follicle damage (e.g., from extensions, trauma, or burns) can delay or prevent regrowth
- Medical conditions like alopecia or chemotherapy can extend regrowth times to several months or longer
- Nutritional status and use of lash serums or supplements may help speed up regrowth, potentially shortening it to around 4 to 6 weeks
- Stress, hormonal changes, and infections can also affect the timeline
In summary, under normal healthy conditions, eyelashes grow back within about 6 to 8 weeks, but it can take up to 3 months or longer depending on individual circumstances and underlying causes
