Founded in 2005 in Cambridge, Massachusetts by a group of MIT-trained scientists led by Bob Langer — one of the most cited chemical engineers in the world. The brief was unusual for haircare: solve problems the category had stopped trying to solve, and patent the molecules along the way.
The first breakthrough was PolyfluoroEster — a polymer that repels dirt and oil, sold inside Perfect Hair Day. The second was OFPMA, a humidity-resistant polymer behind the No Frizz range. Jennifer Aniston became a co-owner and creative partner in 2012, raising the brand's profile without softening the science.
Acquired by Unilever Prestige in 2016. In 2023, the brand released Triple Bond Complex — its direct answer to Olaplex No.3. The launch repositioned the brand for the bond-repair conversation and gave it a second hero alongside Perfect Hair Day.
