Eyelashes typically take between 6 weeks and 3 months to fully grow back, depending on the cause of the loss and the health of the hair follicle and eyelid
. The eyelash growth cycle has three phases:
- Anagen (growth) phase: lasts about 4 to 6 weeks (30 to 45 days), during which the eyelash actively grows at a rate of about 0.12 to 0.14 mm per day
- Catagen (transition) phase: lasts 2 to 3 weeks, when growth stops and the follicle shrinks
- Telogen (resting) phase: lasts around 6 to 12 weeks (up to 100-150 days), when the eyelash falls out and a new one begins to grow
If eyelashes are pulled out or fall out naturally, regrowth usually takes about 6 to 8 weeks, but it may take longer if the follicle is damaged or due to underlying health issues
. Conditions like chemotherapy, alopecia, or thyroid disease can extend the regrowth time to several months
. To potentially speed up eyelash regrowth, some people use prescribed or over-the-counter growth serums and take vitamins such as biotin, vitamin A, vitamin C, iron, and omega-3 fatty acids
. However, caution is advised with home remedies to avoid eye irritation or damage. In summary, under normal healthy conditions, expect eyelashes to grow back in about 6 weeks to 3 months. More severe damage or health conditions can prolong this period significantly
