Function of Beauty vs Prose Hair
Side-by-side comparison of AI visibility scores, market position, and capabilities
Algorithm-driven personalized haircare brand available at Target and CVS across thousands of US store locations; pioneered mass-market hair customization at accessible price points, expanding personalized beauty from premium DTC to mainstream retail.
About
Function of Beauty is a New York-based personalized haircare brand founded in 2015 by Zahir Dossa and Hien Nguyen. The company uses a proprietary algorithm and quiz-based system to formulate custom shampoo, conditioner, and hair treatment products from a matrix of active ingredients, fragrances, and color dyes. Products are manufactured to order and shipped directly to consumers with their name on the bottle.\n\nFunction of Beauty differentiated from Prose by targeting a broader, more price-sensitive consumer segment and aggressively expanding into mass retail. The brand entered Target in 2020 and later CVS, growing to thousands of store locations nationwide. This retail-first expansion made personalized haircare accessible at drugstore price points rather than premium DTC-only tiers. The company has also launched personalized skincare and bodycare lines.\n\nThe brand faced market headwinds in 2024 as consumer interest in personalized beauty matured, but it retains its position as the most widely distributed customized haircare brand in the US. Function of Beauty has raised over $150 million in venture funding and continues to iterate on its personalization engine with AI-driven ingredient recommendations and expanded formula options.
AI-personalized hair and skincare DTC brand achieved $165M revenue in 2024 with 29% growth; expanded into custom skincare in 2025; manufactures all products in Brooklyn with a West Coast expansion adding production capacity and reducing shipping times.
About
Prose is a New York-based personalized beauty company founded in 2017 that uses a proprietary algorithm to formulate custom shampoos, conditioners, hair masks, and skincare products based on an individual consumer consultation covering hair type, scalp condition, lifestyle, and environmental factors. The company manufactures all products in small batches in its Brooklyn facility.\n\nProse achieved $165 million in annual revenue in 2024, representing 29% year-over-year growth, making it one of the fastest-scaling DTC beauty brands in the US. In 2025, the company expanded aggressively into custom skincare — applying the same personalization engine to cleansers, serums, and moisturizers — and opened a second customization center on the West Coast to reduce shipping times and scale production capacity.\n\nThe brand released its first national TV advertising campaign in 2025, signaling a move toward broader mainstream awareness beyond its core DTC subscriber base. Prose competes with Function of Beauty in the personalized haircare space but differentiates through in-house manufacturing, dermatologist-reviewed formulas, and a premium pricing tier that skews toward skincare-savvy millennials.
