Eyebrows generally take about 4 months to fully grow back, as the complete eyebrow hair growth cycle lasts roughly that long. This cycle includes three phases: anagen (growth), catagen (transition), and telogen (resting), with the anagen phase for eyebrows lasting about 30 to 45 days, much shorter than scalp hair
- Initial visible regrowth can appear within 3 to 4 weeks after hair removal like tweezing or waxing
- Full regrowth typically takes 2 to 4 months, depending on individual factors such as genetics, age, hair type, and whether the hair follicles are healthy or damaged
- If the follicles are damaged (e.g., from over-plucking), regrowth may be slower or incomplete, and treatments like minoxidil might be needed
- After shaving, eyebrows can regrow faster, with visible stubble in a few days and full regrowth in about 6 weeks because the follicle is not removed
- Eyebrow transplant results take longer, with initial shedding in 2-4 weeks, new growth starting around 3-4 months, and full results visible at about 12 months
In summary, for most people, eyebrows take about 6 to 8 weeks to show significant regrowth and up to 4 months to fully grow back under normal conditions
