Styles by Rita-Rose, Los Angeles

Health and cleanliness rank just as high as beauty on Blo and Fil's priority list—so much so, in fact, that the blow-dry and threading salon sticks solely to natural products, right down to the organic honey that customers use to flavor their tea. For the hair side of the business, it partners with Qaba, an Australian company that crafts certified-organic shampoos and conditioners with natural essential oils, helping give Blo and Fil's signature blowouts extra oomph in scent and texture. For the brow side of the salon, beauticians first clean faces with natural witch hazel, before strategically removing unwanted hairs with a thread—a highly hygienic way to preen faces without harming or hurting the skin.
