Nick Burns writes about laser hair removal:
The new slew of hair-slowing potions don’t impress some dermatologists. “There is a lot of discussion involving these products and little actual scientific research to substantiate the claims,” said Dr. Neil Sadick, a clinical professor of dermatology at Weill Medical College of Cornell University in New York. “Saw palmetto is a weak enzyme inhibitor, so theoretically it might slow hair growth on the face,” Dr. Sadick said. “But it has never been proven to work that way.” And palmatine? If in fact it does hamper the division of cells responsible for hair growth, then, Dr. Sadick said, it would be similar to Vaniqa, the only prescription medication of its kind approved by the Food and Drug Administration. (Vaniqa is usually prescribed to women with unwanted facial hair.)
