It’s official: Botox isn’t just for your face anymore! After years of gaining momentum as an alternative use, we can now call Blotox, the act of getting Botox injected into your scalp to decrease sweating — and extend blowouts — a full-on trend.

“I have been doing Blotox for about eight years,” dermatologist Dr. Michelle Henry tells Us Weekly. “I had a number of patients that were resistant to working out because they didn’t want to ruin their hairstyle or blowout. It makes a huge difference for the working woman who wants to be fit but still look great. For patients with curly or kinky hair, their hair will remain straight longer.”

Stylish knows it can be tough to choose between working out and having to wash and totally redo your hair, so this sounds like a great solution!

“They won’t sweat as much so their blowout will last longer and their hair won’t feel or look as greasy,” dermatologist Dr. Cindy Bae told Us. “It’s interesting to see how much Blotox has taken off.”

One reason we speculate why: the growing trend of sudsing up less to preserve hair health. See: the low-‘poo, no-‘poo and all the other ‘poo (as in shampoo) movements.

Although Botox is only FDA approved to treat crow’s feet, forehead and frown lines, dermatologists have been using it off-label for years in various surprising places. Patients can get Botox in their armpits for excessive sweating, and now men can even opt for Scrotox to make their nether regions less wrinkly.
