Eyebrows typically take about 6 to 8 weeks to show noticeable regrowth after being plucked, waxed, or shaved, but full regrowth usually takes around 2 to 3 months under normal conditions
. This timeline depends on the natural hair growth cycle, which includes three phases:
- Anagen phase (growth phase): Lasts about 30 to 45 days for eyebrows, during which hair actively grows.
- Catagen phase (transition phase): Lasts around 2 to 3 weeks, where hair growth slows and follicles shrink.
- Telogen phase (resting phase): Lasts 2 to 4 months, when hair rests before shedding and new growth begins
Because eyebrow hair has a shorter anagen phase compared to scalp hair, eyebrows grow back more slowly. Individual factors such as age, genetics, hair type, overall health, and whether the hair follicles are damaged can affect the regrowth speed. For example, damaged follicles may delay or prevent regrowth, sometimes requiring treatments like minoxidil
. In cases of eyebrow transplants, initial shedding occurs within 2 to 4 weeks, with new growth starting around 3 to 4 months post-procedure and full results visible after about 12 months
. In summary, most people will see eyebrow hair start to grow back visibly in about 4 to 6 weeks, with full regrowth taking 2 to 3 months, though this can vary widely based on personal and health factors
