At what approximate rate do toenails grow per month?

1. 1 mm

2. 2 mm

3. 3 mm

4. 4 mm

The correct answer is: 1 mm

The growth rate of toenails is typically around 1 millimeter per month. This relatively slow growth rate is influenced by various factors, including age, health, and even the season. Nail growth varies between individuals, and toenails generally grow slower than fingernails due to less blood flow and mechanical stimulation. In contrast, other growth rates listed in the choices may be based on misconceptions or generalized perceptions. For instance, 2 mm or more per month would be considered unusually fast for toenail growth and is not commonly supported by scientific data on average toenail growth. Understanding this rate is helpful not just for personal grooming but also for recognizing potential health issues that could affect growth patterns.
