Cameron Diaz says she's not in to the popular beauty habit of removing pubic hair.

In her new book, The Body Book: The Law of Hunger, the Science of Strength, and Other Ways to Love Your Amazing Body, the 41-year-old devotes an entire section to lady bits, titled "In Praise of Pubes".

"I hear that there's a big fad these days of young women undergoing laser hair removal on all of their lady bits," Diaz casually wrote, according to Gawker.

"Personally, I think permanent laser hair removal sounds like a crazy idea. Forever? I know you may think you'll be wearing the same style of shoes forever and the same style of jeans forever, but you won't. The idea that vaginas are preferable in a hairless state is a pretty recent phenomenon, and all fads change, people."


She went on: "Do you really want a hairless vagina for the rest of your life?"

Diaz explained to readers that pubic hair is not only there for women's health, it's also "a pretty draping that makes it a little mysterious to the one who might be courting your sexiness."

Experts backed Diaz's argument for hair down there. Dr Lauren Streicher told Medical Daily that pubic hair decreases friction during sex. Meanwhile, Dr Emily Gibson said the hair protects the genitals from bacteria and other unwanted nasties.

"Pubic hair removal naturally irritates and inflames the hair follicles left behind, leaving microscopic open wounds," Dr Gibson wrote to Medical Daily. "When that irritation is combined with the warm moist environment of the genitals, it becomes a happy culture media for some of the nastiest of bacterial pathogens."

Diaz said her call to keep her hair is a "personal decision."

"But I'm just putting it out there: Consider leaving your vagina fully dressed, ladies. Twenty years from now, you will still want to be presenting it to someone special, and it would be nice to let him or her unwrap it like the gift that it is."
