We are rewriting the rules of beauty — by putting you in charge.
Our Founders

Our Approach
Every ingredient in your formula is intentional. We focus on select, targeted, high-performing ingredients, expertly combined in the right concentrations to work best for your hair.
We deliver freshly formulated, customized hair care right to you, minimizing waste, and ensuring you get everything you need — and nothing you don’t.
Only 27% of those working in STEM are women. Because we are scientists at heart, we strive to facilitate access to science by proudly partnering with GirlStart.
