About the Professional Molecular Repair Hair Mist

The K18 Professional Molecular Repair Hair Mist is a leave-in treatment for damaged hair. It uses K18Peptide technology, which is designed to mimic the natural structure of keratin and reconnect broken keratin chains. It targets damage from heat styling, chemical treatments and environmental stress.

The mist is lightweight and absorbs quickly without leaving residue. It is meant to reduce split ends and breakage, strengthen fragile strands and improve elasticity, smoothness, shine and bounce without weighing hair down.

To use it, mist it onto damp, towel-dried hair, leave it in and style as usual. No rinsing is needed. It can be used daily or frequently without causing buildup.
