A shave and a haircut is worth a lot more than two bits these days.

The folliclely focused fields are experiencing a renaissance, not just in the rise of boutique salons and barber shops that double as bars but also in the number of people learning the profession. Cosmetology and barber schools is the No. 1 fastest growing industry for 2011, according to AnythingResearch.com. The schools train both stylists and potential entrepreneurs who may someday open their own salons.

Most states require licensing for stylists, so the schools indicate a required step before entering the field. Trade schools thrived during the economic slump, and according to IBISWorld, professional skills and performance training has potential to grow 5.3 percent every year until 2016. Educating future coiffeurs is a trade itself, with an exceptional year-over-year growth rate of 29 percent, according to data from AnythingResearch.com.

Charles Kirkpatrick, the executive officer of the National Association of Barber Boards of America, recently told the New York Times the number of licensed barbers had grown roughly 10 percent in the last two years, to 245,000 from 225,000.

It's not just a barbershop boomlet, though: Nail salons are part of this fast-growing industry, with a 9 percent year-over-year growth rate, as estimated by AnythingResearch.com. With an average company size of $168,703, the barrier to entry is extremely low.
