How long does it take eyebrows to grow back?

Eyebrow hair typically grows at a rate of about 0.16 mm (0.0063 in) per day, or about 2.2 mm (0.087 in) per month. However, this can vary depending on a number of factors, including age, genetics, and diet. In general, it takes about 6-8 weeks for eyebrows to fully grow back after being shaved or plucked.
