Function of Beauty is a direct-to-consumer beauty and personal-care brand built around personalization, best known for quiz-driven customizable hair care (shampoo and conditioner) and skin and body products formulated to an individual profile. The company sells online through a Shopify-hosted storefront. Its customer-facing programmatic surface is therefore the Shopify commerce platform: a live hosted Storefront MCP server at /api/mcp (product search, cart, policies, product details) and the Shopify Customer Account API exposed through OpenID Connect discovery on the company domain. Function of Beauty was added to the API Evangelist network as a GGV Capital portfolio company and enriched from its public discovery surface.
