the experts know

Groundbreaking PRO stylists, scientists + beauty experts have unlocked new levels of expression with K18 molecular repair.

where molecular repair works

so what's the molecular repair difference?

No bragging, just facts. Learn how we're truly repairing hair
us
the K18PEPTIDE™ works at the innermost layers of the hair fiber to reconnect broken polypeptide chains, restoring hair strength + elasticity
them
Traditional products work on the outermost layer of the hair (the cuticle) for surface-level results. Bond builders work just below the surface at the top layer of the cortex
us
As a result of this reconnection, disulfide bonds (those things bond builders talk about) are also reconnected
them
Since these products sit on top of the hair or just below the surface they rinse out when hair is washed
us
Because of WHERE + HOW we work, molecular repair is able to offer true lasting + progressive results
them
Because of WHERE + HOW these products work, they can only cover up or temporarily address damage
