Does hair grow faster in the winter or the summer?

Contrary to popular belief, seasons do not affect hair growth. The biggest factor when it comes to the rate of hair growth is genetics.

Some people have a faster hair growth rate, while others grow hair more slowly. Other factors that increase the growth rate of the hair includes a person's diet and the overall health of the hair. Getting hair trimmed every 3 to 4 months to do away with split ends can help it maintain its health and strand strength. Hair can also be kept healthy through eating a diet that includes lots of fruits and vegetables.
