Naturally powerful and
proven effective
Every ingredient is meticulously researched by our world-class R&D team and sustainably sourced from trusted partners around the globe. If it’s not high quality or highly efficacious, we won’t use it.
Leading with lab innovation
Our in-house chemists endlessly test different combinations of high-performing natural and synthetic ingredients — for uniquely personalized formulas and always-improving results.
Everything you want (and nothing you don’t)
Our formulas are cruelty-free with zero parabens, sulfates, phthalates, mineral oils, or GMOs. We can even make yours vegan, silicone-free, dye-free, or fragrance-free.

Our Ingredient Index
Here’s what we’re working with. Every Prose formula is a unique combination chosen from these safe and sustainable ingredients. We’ve also included the EWG scores of each—we’re proud that the vast majority come in at 1. Just like in golf, we’re always going for a lower score here.
