Redken offers an online Hair Quiz on redken.com that uses an algorithm to recommend a personalized hair care routine to shoppers based on their answers about hair type, texture, concerns, and lifestyle goals. Results are delivered in about two minutes and include specific Redken product recommendations.

The Redken Hair Quiz and Hair Styling Quiz are available on redken.com and redken.ca. The company describes the system as powered by 'our advanced algorithm to offer perfectly tailored professional recommendations,' with each answer guiding the system toward a customized hair routine. The quizzes accept user-provided inputs about hair characteristics and goals, and output a curated product regimen. A separate Redken Hair Styling Quiz applies the same format to styling product recommendations. The tool is positioned as replacing or supplementing the in-salon product consultation experience for at-home shoppers.
