How often are eyebrow hairs and eyelashes replaced?

Every month
Every 2 to 3 months
Every 4 to 5 months
Every year

The correct answer is: Every 4 to 5 months

Eyebrow hairs and eyelashes typically undergo a growth and shedding cycle, which varies among individuals. The average lifespan for eyebrow hairs falls within a range of 4 to 5 months. This duration is influenced by several factors, including genetics, health, and age. During their growth phase, hairs increase in length and thickness, but eventually, they reach maturity and fall out, being replaced by new hairs. Understanding this cycle is essential in the context of skincare and grooming, as it impacts how often one should consider reshaping or maintaining their eyebrows. In contrast, the other timeframe options either underestimate or overestimate this cycle. Hair growth that occurs every month or every year would not accurately reflect the typical replacement rate of eyebrow and eyelash hair. Thus, recognizing that a 4 to 5-month cycle is standard helps in accurately managing grooming and expectations regarding hair maintenance.
