Fingernails grows fast on your left hand

The American Academy of Dermatology (AAD) says that a fingernail takes around six months to grow from base to tip and that toenails can take up to a year to do the same. But there are some factors that make nails grow faster. According to the AAD, fingernails grow faster on your dominant hand, as well as on your bigger fingers. They also grow faster during the daytime and during the summer months.
