About
Function of Beauty is a pioneering personalized hair care platform that leverages data-driven formulation to deliver custom hair products matched to each individual customer. Users begin with a two-minute hair quiz covering hair type, texture, history, damage level, styling habits, and personal hair goals. Based on the responses, Function of Beauty formulates a made-to-order shampoo, conditioner, leave-in treatment, or full SOS Custom Repair system—prioritizing naturally-derived, clean ingredients backed by scientific testing. The brand is 100% vegan, cruelty-free, sulfate-free, paraben-free, and dermatologist tested. Clinical results highlight up to 2x stronger hair and 90% less breakage with the complete system versus untreated hair. Products are available for all hair types and textures, from pin-straight to tightly coiled, and include solutions for highlighted, color-treated, heat-styled, and chemically processed hair. Function of Beauty ships directly to consumers via its website and also offers a subscription model for ongoing, discounted delivery. The platform is ideal for anyone frustrated with off-the-shelf hair products and seeking a more targeted, personalized approach to hair health. It appeals to a broad consumer audience including those with specific damage concerns, curl patterns, or styling routines that generic products fail to address.
