Nah, more like:
Man: Washes hair daily. That's it.
Woman: Only washes/wets hair sometimes. Uses lots and lots of various chemicals to force various styles. Lots of blow drying. Hair dyes. Then wonders why hair is obviously chemically and physically damaged.
The problem is most women put TOO much effort into their hair, trying to make it things it's not, and end up damaging it. Men tend to keep it short and simple and their hair doesn't end up as damaged.
Also, you notice the Fabio guys a lot more than you notice the broccoli haired dorks. You remember that one hot guy more than you remember the dozens of unkempt ones. Add in that people who can't grow nice long hair tend to keep it short and you have all kinds of selection biases.
