Sephora's nearest audiences span an unusually wide range of retail and service categories, with no single neighbor pulling far ahead of the rest — the top 10 scores run from 0.95 down to 0.91, a narrow band that signals a flat shape rather than any concentrated overlap.

The leading neighbor is Beauty Salons & Spas at 0.95, followed closely by HomeGoods at 0.94 — a home goods retailer sitting nearly as close as a direct beauty-adjacent service. European Wax Center (EWC) (0.92) and Cosmetic Services (0.91) bring two cosmetic-service neighbors into the set, but they don't dominate it. Petco (0.92) and LensCrafters (0.91) sit at comparable scores, pulling the cluster well outside beauty. Men's Apparel (0.91), Massage Envy (0.91), Orangetheory Fitness (0.91), and Pet Supplies & Services (0.91) round out the ten. Tallying subcategories across the top 10: Beauty Salons and Spas appears twice, Cosmetic Services twice, Pet Supplies and Services twice, and Fitness Centers and Gyms once — alongside Eyewear, Home Goods and Furnishings, and Mens Apparel. No single subcategory controls the cluster. Notably, no other Beauty and Cosmetics retailer — Sephora's own subcategory — appears in the top 10.

The flat shape here reflects an audience whose composition is shared broadly across personal-care services, specialty retail, and wellness — a profile that looks less like a beauty-category audience and more like a general suburban consumer audience that happens to index across many in-person service and retail categories simultaneously.
