Apparently no one can prove 100% that hair grows faster in the summer
Here is an article from Oprah.com.
BUT, some say it grows 10 to 15 percent faster, because warm weather enhances blood circulation to the skin and scalp, which in turn nourishes hair cells and stimulates growth.
Others think an increase in fresh fruits and vegetables and a natural hormonal shift and increase in UV rays in warmer months could pay off with faster growth.
Why do we care? Because let’s face it, if hair grows faster we need more maintenance! Boom Boom says start with a professional wax and then DO NOT TOUCH BROWS FOR 1 MONTH. Not at all!! The goal is to get hair on the same growth cycle so it grows in and can be removed at the same time. Once hair is on the same cycle, brows can be groomed just once a month.
