Apparently we wash our hair entirely too much.

Or so says this interesting NPR news item that covered some folks who are cutting way back on shampooing their hair.

Americans love to shampoo. We lather up an average of 4.59 times a week, twice as much as Italians and Spaniards, according to shampoo-maker Procter & Gamble.

But that’s way too often, say hair stylists and dermatologists. Daily washing, they say, strips the hair of beneficial oil (called sebum) and can damage our locks.

I don’t shampoo anywhere near as much as I used to because I shave my head, but back when I had a full head of hair I shampooed daily. If I didn’t my hair definitely got greasy because I’m cursed with very fine hair that was easily weighed down by the oil and almost impossible to style. In fact I started showering in the morning because if I washed my hair prior to bed it’d be back to greasy-sticky-outy-all-over-the-damn-place by the time morning rolled around. According to the article I should have just lived with the greasy hair:

“If you wash your hair every day, you’re removing the sebum,” explains Michelle Hanjani, a dermatologist at Columbia University. “Then the oil glands compensate by producing more oil,” she says.

She recommends that patients wash their hair no more than two or three times a week.

As I said before these days I tend to shave my head, but I only do that once every couple of weeks or so which allows my hair to grow out an inch or two between shavings. For the week or so I don’t bother using shampoo at all, but once it gets to an inch I start using small amounts every other day. Eventually it gets long enough that I have to go back to daily shampoos unless I shave it off again. All of which I suppose is a good argument to shave my head more often.
