Expert Insight

A former Function of Beauty Product Leader stated, "Function of Beauty's biggest strength is its data-driven formulation engine, but its main challenge is educating consumers on the value of personalization in an industry dominated by one-size-fits-all products."

Product Overview

Function of Beauty solves the problem of generic haircare products that don't address individual hair needs and goals. Its target audience is primarily millennials and Gen Z consumers who value personalization, sustainability, and are willing to pay a premium for products tailored to their specific hair type and concerns.

The product has evolved from a simple shampoo and conditioner offering to a comprehensive haircare system including styling products, body care, and most recently, skincare. This expansion reflects a strategic shift from a niche player to a holistic beauty brand.

Key Takeaway

In the past 7 years, Function of Beauty has evolved from a custom shampoo and conditioner service to a full-fledged personalized beauty platform, expanding its product range and technological capabilities.

Currently, Function of Beauty holds a unique position in the market, bridging the gap between mass-market haircare brands and high-end salon products. Its use of technology to create personalized formulations at scale sets it apart from traditional beauty companies and positions it as a leader in the growing trend of customized consumer goods.

User Journey Deep-Dive

The Function of Beauty experience begins with a comprehensive hair quiz. This onboarding process is crucial for both data collection and setting user expectations. The quiz covers hair type, structure, scalp moisture, and hair goals, using simple language and visual aids to ensure accuracy.

Key user flows include:

  1. Quiz completion and product customization
  2. Reviewing and adjusting formulations
  3. Subscription management
  4. Product usage and feedback loop

The critical features defining the user experience are the AI-powered formulation engine, the ability to choose fragrance and color, and the option to adjust formulations over time based on results.

One pain point users often encounter is the initial adjustment period when switching to customized products. To address this, Function of Beauty introduced a "Consultation" feature, allowing users to speak with hair care experts for personalized advice. This has improved customer satisfaction scores by 15%.

Retention is driven by a subscription model with flexible delivery frequencies and the ability to easily modify formulations. The brand also leverages email marketing to educate users on proper usage and encourage them to update their hair profiles as their needs change.

UX & Design Analysis

Function of Beauty's information architecture is designed to guide users smoothly from quiz to purchase. The navigation is intuitive, with clear categorization of products and easy access to account management and subscription controls.

The mobile experience closely mirrors the desktop version, with responsive design ensuring functionality across devices. However, the mobile app offers additional features like tracking hair health over time and setting reminders for product usage, enhancing the overall user experience.

Standout UI elements include:

  • Interactive hair goal selectors with clear icons
  • A dynamic bottle preview that updates in real-time as users customize their product
  • An intuitive slider for adjusting formulation strength
