If comb sales are any indicator of men's hairstyles, we should expect to see a rash of men suffering from a prolonged bad hair day. According to market research firm ACNielsen, unit sales of combs have been steadily thinning for the past year. In fact, nearly half a million fewer combs flew off the shelf and into back pockets this past March than did in March of 1999. What gives? Salon director Rajesh Gulab at Jean-Claude Biguine in New York City says the trend for men - especially younger ones - is to spend as little time on their hair as possible. "Their fingers become the comb," he says. But if time is money, guys are trading plenty of it in for pomades and texturizers, perfect for maintaining that "I just rolled out of bed" look. Just a year ago, these styling products comprised 0.4 percent of the hair preparation market. Today, they're up to 1.9 percent.
