Is My Hair Growing Quicker in the Summer?

This isn’t a hair loss question, but I am curious about the rate of my hair growth. I find my hair growth occurs more rapidly during the summer months. Is this normal? I usually get a haircut every 4 weeks or so, but in the summertime I find myself at the barber every 2-3 weeks because it gets out of control. With summer a few months away, it got me thinking that I need to put aside some extra cash for more barber time.

I have heard about this observation before (though I tend to hear this more about winter months rather than summer), although there is no documentation in the clinical science literature about it. It may not be a general rule, but what you’re seeing is probably appropriate for your situation.

I’ve written before about seasonal hair loss here.
