* Fingernails: It typically takes about 4-6 months for a fingernail to fully regrow.
* Toenails: Toenails grow much slower and can take 12-18 months (or even longer) to regrow completely.
Several factors can influence these timelines, including:
* Age: Nails tend to grow faster in younger people.
* Health: Certain medical conditions and nutritional deficiencies can slow nail growth.
* Trauma: Injuries to the nail bed can sometimes affect nail growth.
* Season: Some studies suggest nails grow slightly faster in the summer.
* Dominant Hand: Fingernails on the dominant hand may grow slightly faster.
