Redken offers the Style Station app to salon professionals, which includes a formula finder tool that takes a stylist's inputs about a client's starting hair level and desired goal level and outputs a recommended Redken hair color formula. The app is available for free on iOS and Android.

The Redken Style Station app's Formula Finder allows stylists to select a hair color line, input the client's current hair level, gray hair percentage, and desired target level, and receive a specific color formula recommendation. The app also includes a Color Converter feature described as an 'intelligent Color Converter' that translates formulas from other hair color brands directly into Redken equivalents. According to Redken's official page, the formula database contains thousands of shades. The app is described as designed for use 'behind the chair,' meaning during live salon client sessions.
