I had lunch with my friend Michele recently, after which she said she was headed to a hair appointment.
"Summer is always the worst," she said. "My hair grows faster, so I end up at the stylist more often."
Really?! Just when I think I've heard it all, some new hair tidbit gets me wondering. I ran the concept past my hair stylist.
"So Jeff, does hair really grow faster in the summer?"
"Yup. It does. And I have no idea why."
A few weeks later, I brought up the subject with Dave and friend Eric, visiting from Austin.
"Why do you think it grows faster?"
"Maybe increased sunlight?" suggested Eric.
"Ooo, that's a good one. Like photosynthesis and tree leaves. Or wait, maybe it's like the tides and the moon -- hair grows faster as the sun reaches its zenith in the northern hemisphere?"
O Magazine. Brian Thompson, senior trichologist (hair specialist) at Philip Kingsley Trichological Clinic in New York City, says "there are no reliable statistics about it, but warm weather does seem to make hair grow faster." Talk about your non-answer.
eHow explains how hair growth increases about 0.05 inches, due to faster cell division, spurred by an increase in certain hormones in warmer months of the year.

Ha! I prefer photosynthesis and tree leaves. After all, when my hair isn't combed, my brother points out, I look just like a plant.
