15 Best Aluminum-Free Deodorants to Shop in 2024

“When people make the change from conventional antiperspirants to ‘natural’ deodorants, they can notice that they are smellier than they are accustomed to being,” the expert adds. “The idea is that an armpit detox can make this transition easier.” The detox in question is similar to a deep-cleansing face mask, but for your underarms. “Armpit detoxes usually consist of a homemade mask of bentonite clay and apple cider vinegar, and some also include water to dilute the vinegar.” (King recommends not skipping the water step.)

The mask is then applied and left on armpits for five to 20 minutes before rinsing. However, King advises, “There's no proof that these masks can reduce odor, but deodorants, antiperspirants, and these masks can affect the amounts and types of bacteria in the armpit, and the amounts and types of bacteria are largely responsible for odor.”
