Teri Hatcher (search) is hiding her gray hair — and she's not shy about talking about it.

Hatcher, one of the stars of ABC's "Desperate Housewives" (search), is the new spokeswoman for Clairol's Nice 'n Easy (search) hair color. The natural brunette, who's had a spot of gray since she was 25, uses medium golden brown.

"I'm not the kind of person who can get involved in things I don't believe in. I'm a very honest and open person. I'm not a good liar. I might be an OK actress but I'm not a good liar," she told The Associated Press in a recent phone interview.

Hatcher will star in both print and TV ads.

"In all my career, in my ups and downs, I've never had a beauty campaign. This was meaningful that at almost 41 years old, I could be getting my first beauty campaign," she said. "It made me feel really great."

Hatcher said the product fits her personality and lifestyle.

"My daughter is much more important to me than how I look that day, so on days when I'm rushing to get my daughter to school and rushing to work, if I don't have to worry about my hair looking good, then it's a good thing," she said.

But the day she shot the TV spot in Los Angeles, the Clairol team paid more attention to her hair in a few hours than she does the rest of the year, Hatcher said with a laugh.

"Every last strand was in place — and it looked good. But I came home with my perfect hair and took a shower," she said.

Patrice Louvet, vice president of global hair colorants for Clairol, said Hatcher was a perfect match for the at-home product.

"She's an accomplished actress who has successfully reinvented herself in her career. ... Both Teri and Clairol have a similar appeal and a similar personality. They're approachable, natural, relatable," he said.

Clairol worked with Linda Evans ("Dynasty") in the 1980s and Julia Louis-Dreyfus ("Seinfeld") in the '90s.

"A celebrity allows the woman at home to identify with someone, which you don't get with a traditional model," Louvet said.
