Great article on female hair loss from Marie claire

"Stylists always gushed, "Wow, you've got a lot of hair." I took my lush mane for granted, perming, straightening, and bleaching my way through my teens. But during my sophomore year of college, as I found myself pulling more and more tangles out of my brush and strands from the shower drain, the compliments stopped and the worry began. I jealously examined the girl next to me on the subway — why couldn't I see through to the roots on her scalp, too? Once a sheet of shiny darkness, my hair had taken on an alarmingly transparent quality. I spent hours every week staring at my scalp in the mirror, parting and reparting my hair to see which side looked fuller. I drenched my head with volumizing sprays, detoxifying tonics, and shampoos for "weakened hair." Remedies were thick on the ground — but my hair kept getting thinner. I was molting. And I was scared.

Like a peacock's brilliant feathers, hair is a secondary sexual characteristic, explains London trichologist Dr. Philip Kingsley. "You don't need it to keep you either warm or cool, so its primary function is to increase attractiveness." We live in a culture of hair, coveting Victoria's Secret supermodels' voluptuous waves as much as their curves. So closely linked are sex appeal and self-esteem that a 2004 Rogaine survey of more than 500 women across the U.S. revealed that 24 percent equated losing their hair to losing a limb. Since 30 million women in America — roughly one in four — have thinning hair, there's a serious portion of the population at risk for an emotional crisis."
