Liv might want to think twice about her date with the Dominatrix of Hair.

Researchers for L’Oreal in Paris claim they’ve gotten to the root of what causes curls. The answer, they say, lies below your scalp in the hair bulb — which is hook-shaped for curly hair and straight for straight hair.

L’Oreal’s scientists believe those bulbs could be altered using hormones, meaning popping a pill could turn curly hair straight and vice versa.

Dermatologists say it could work.

“I think this could be potentially revolutionary if it actually changed the shape of the bulb within the hair follicle,” said Dr. Diane Berson, a dermatologist at New York Presbyterian Hospital.

L’Oreal said its research could also lead to a pill that changes gray hair back to its original color. (Source: ABC News.)

As someone who’s perennially pissed off at my own hair and threatening to shave it all off, I’m excited about this news. I wouldn’t make nearly as good looking a bald chick as Natalie Portman does.
