Other factors that affect the growth of toenails
There are other factors that affect the growth of toenails. For example, nails grow slower in older people and in colder climates. Nails regrow quicker in summer.
Nails on frequently used would grow faster than nails on the other hand. For example, left-handed people grow nails faster on their left hand than their right hand.
Experts also suggest that trauma or an injury increases the rate of regrowth, because of an increase in blood flow to the injured area.
The general health of an individual also contributes to the growth of nails. It gets slower when you are sick or malnourished. Hormones [4] also affect regrowth; your toenails and fingernails grow faster during pregnancy.
