Our Mission

At Prose, we don't believe in "one-size-fits-most." We create custom hair care that's inclusive to all hair types, needs, and preferences. Each of our hair care products is customized to a person's hair needs based on the results from an online consultation. The individual data is processed through a proprietary algorithm and made-to-order in the Prose lab using natural active ingredients. Marrying emerging technologies with the best in beauty, Prose is truly creating something special.

This is the opportunity to join a fast-growing startup and an energetic team that works together to deliver creative solutions that are transforming the way people think about and shop for hair care. We're looking for talented problem solvers who lead with passion and who face any task with a positive mindset.
