How many days does it take to regrow your nails?

Nail growth varies by individual, but on average, fingernails grow about 1/8 inch (3 mm) per month. It typically takes about 3 to 6 months for a fingernail to fully regrow from the base to the tip after being cut or damaged. Toenails grow more slowly, averaging around 1/16 inch (1.5 mm) per month, and may take 6 to 12 months to fully regrow. Factors such as age, health, and nutrition can influence the growth rate.
