Which is your fastest growing fingernail? A - Thumb
B - Middle finger
C - Pinky
Answer: B - Middle finger Fingernails grow at an average rate of 3.47 millimetres per month. However, not all fingernails grow at the same rate. The fastest growing nail is the one on your middle finger, which is usually the longest finger. The rate at which your nails grow is affected by a number of factors including your age, gender and hormones. For example, men’s nails tend to grow faster than women’s, with the exception of women’s nails during pregnancy. Your fingernails also grow faster during the day and during the summer. Strangely, the nails on your dominant hand grows faster than the nails on your non-dominant hand.
