If you hate shaving as much as I do, you might say "yes!" to No!No!. This small, portable hair removal device promises to destroy hair painlessly using thermal technology. The heat gently destroys hair by crystallizing the top part of the follicle, stopping up to 64% of hair growth over time. It isn't a miracle cure, nor does it provide overnight results. You'll need to use No!No! two or three times a week for the first two months, but it pays off: A study found that on average, hair reduction reached 45% after eight weeks of use.

Compared with shaving, waxing and laser treatments, No!No! has a few advantages. It's less likely to cause ingrown hairs, it's pain-free and it works with short, light hairs as well as longer, darker ones. I'm eager to try this out when it launches at Sephora next month—and of course I'll let you know how well it works.
