Both toenails and fingernails grow slowly, with toenails taking longer to regrow.⁠ On average, it can take up to 18 months for a toenail to completely regrow, and about 4 to 6 months for a fingernail to grow back.⁠ The reason fingernails grow faster isn’t fully understood. But according to one theory, fingers receive more blood flow because they’re used more often, which likely contributes to faster fingernail growth.⁠ Although it can take months for nails to grow back, the rate of regrowth can be faster or slower depending on the scenario, as shown in the following table.⁠ ⁠ _____⁠ ⁠ ⁠ #science #biology #toenail #wow
