mes° is biodesigned by Arcaea, where scientists believe biology still has a lot more to teach us about beauty.

Biology has been solving extraordinary problems for billions of years. From desert plants that survive years without water to geckos that defy gravity, we believe beauty's biggest challenges aren't inevitable. They're simply biological questions waiting to be solved.

Our most powerful ingredient is curiosity.

Meet the biologist reimagining beauty.

“What fascinated us was realizing that hair is so much more than a dead fiber. It’s a complex biological material, and the more deeply we understand how it works, the more possibilities we uncover for what haircare can do.”

We approach haircare differently.

Biology opens up new possibilities for hair.

  • Jennifer Lawrence with wet, slicked hair holding Multitask Repair Mask.

    Restoring the biology of healthy hair.

    For years, hair repair has focused on proteins and bonds. But when we looked at the biology of healthy hair, we saw that lipids play a critical role. The Multitask Repair Mask dramatically strengthens hair with up to 158% more lipids.

  • A woman with long blonde hair crouching, holding Good Roots Volume Mist.

    The secret to lasting volume.

    Instead of just adding lift, we addressed a biological reason hair falls flat: excess oil at the scalp. Good Roots Volume Mist reduces scalp oiliness by 75%, helping deliver volume that lasts for 72 hours.

  • A woman with long straight dark hair lying on the floor beside Off-Duty Restyling Serum.

    The science of day 2 hair.

    Instead of treating hair as a surface to coat, we studied the biology of how hair changes and holds shape. Off-Duty Restyling Serum helps reorganize that shape, so you can restyle your hair on day 2, 3, 4+ without starting over.
