How fast does the average human fingernail grow?

There are a number of variables that may affect nail growth;





1.)Nail growth is different from person to person and from finger to finger.


The nail on the middle finger grows the fastest and the nail on the little


finger grows the slowest.





2.)Nails grow from 0.05 to 1.2 millimeters per week. If a nail is lost, it


may take seven (7) months to grow out fully.





3.) Biting fingernails, while detrimental to their health in other ways, is


thought to make them grow faster.





4.)Mens nails grow faster than womens do. However, women will experience a


spurt in nail growth just before menstruation and during pregnancy. These


growth spurts are thought to be in response to hormonal activity.How fast does the average human fingernail grow?
about as fast as the Atlantic Rift separates,





you would be equivalent to about 3 millimeters per week
