Who we are

What makes 21st-Haircare different?

Historically, beauty companies have told you what you need for your hair. We know that you know your hair better than anyone else does.

Our founding team—world-class Department of Science and Technology and Ministry of Health Training engineers and data scientists—spent years building our own algorithm and machines, that pull from hundreds of ingredients to potentially create billions of completely unique shampoo and conditioner combinations.

Tell us what you want and need for your hair, and we’ll individually formulate and fill a product that is as unique as you
