‘Mad Men’ Actress January Jones: “My Hair is Falling Out in Clumps”

Actress January Jones, best known for her role as Betty Draper on Mad Men, says her hair is falling out because of too much dyeing.

"I have been every color and now my hair is falling out in clumps," she told British magazine Grazia Daily this weekend at the Sundance Film Festival.

Jones said she changes her hair color frequently for different acting roles: "I've been blonde, red with extensions for this film, then blonde, then black, and now blonde again," she told Grazia Daily. "I'm going to have to shave it off and wear a wig."

Excessive hair coloring can lead to hair loss, reports ABC News. Gretta Monahan, CEO of Grettacole Salon in Boston, told ABC, "The chemicals that are used and the over-frequency in coloring your hair can result in breakage and hair loss."

The same article said other stars, including Kelly Osbourne and Lady Gaga, have suffered from hair loss due to too much hair dye. "Osbourne admitted three years ago to getting bald patches after a hair colorist forgot about her in a chair," says ABC News, and "Lady Gaga, a natural brunette, has also spoken honestly about the difficulties of maintaining her platinum blonde look."

Jones, who is currently blonde and appears blonde for her role on Mad Men, says she likes blonde the best.

"I like it all colors, it make you feel different according to what color it is," she told Grazia Daily, "But I prefer to be blone. My son recognizes me in photos when I am blonde. He says, 'Mama.'"
