One in seven women suffer from hair loss or thinning in their lifetime. Now, some women are trying a noninvasive laser treatment.

Stress, medications, diet and birth control pills can all lead to hair loss. Many women try medications -- which can have side effects -- or surgical methods, like transplants, which can be time consuming and costly.

The Laser Hood resembles a device similar to a hairdryer at a salon. Women can get the treatment for 20 minutes, once or twice a week.

Invisions Hair Loss consultant Jeff El Zenny said the laser stimulates blood flow to the scalp, opening up the hair follicles to receive protein and vitamins the hair needs to regrow.

"Generally, people who qualify for the program, we're getting about 40 percent to 60 percent regrowth," El Zenny said.

Most clients start noticing a difference within a year.

But some women are gaining a full head of hair without it actually growing back, WVIT-TV in Hartford, Conn., reported.

At a hair loss clinic in Connecticut, some women receive a "hair system." It's not a wig, but it is 100 percent human hair that's color-, texture- and wave-pattern matched to a woman's hair color.

When it comes to cost, the Laser Hood averages $200 a month for a year. A hair system typically costs around $2,000.
