How fast do toenails and fingernails grow?
How Fast Do Nails Grow? Nails grow about 1/8 inch per month — so it takes anywhere from four to six months to grow an entirely new nail. Nails grow faster during certain hormonal fluctuating periods, as in the beginning of pregnancy, or just before menstruation. Ironically, nail biting can also increase nail growth since it creates an increased blood circulation. For this same reason, those who are right-handed may notice that nails grow faster on their right hand than on their left. Nail growth can slow down if your diet deprives the nail matrix of nutrients. Any illness can decrease nail growth, as can some prescription medications.
