PROs like you know firsthand how damage-causing aggressors—mechanical styling, sun exposure, and environmental pollutants—can cause breakage, frizz, and dull hair color. When you need to reverse damage, turn to a reparative treatment routine with K18 detox shampoo and K18 molecular repair hair mask, and to protect hair from daily damage, reach for the latest from K18: DAMAGE SHIELD protective conditioner.

Formulated with a biomimetic polysaccharide shield and fortifying ceramide blend, this nourishing conditioner is hair’s first defense against daily damage, created to maintain hair health and improve smoothness and shine. Containing no film-forming silicones or waxes, the DAMAGE SHIELD protective conditioner provides protection for up to three days against mechanical, UV, and environmental aggressors.

Not only is DAMAGE SHIELD conditioner a vital step when conditioning curly/coily hair that’s in need of extra detangling and definition, but it’s also a must during lightening services, which can leave bleached hair sensitive and prone to tangling.

at the salon

The Chelator and PRO mist are essential to prep hair for service, repairing any pre-service damage, and after bleach, the PRO molecular repair mask works to undo damage done during service. The DAMAGE SHIELD protective conditioner provides manageability without weighing hair down. As for how to use it: first shampoo, towel-dry the hair, then apply the PRO molecular repair hair mask, waiting 4 minutes—no need to rinse—before adding the DAMAGE SHIELD protective conditioner from mid-lengths to ends, building as needed. It’s important to keep this order so the K18PEPTIDE™ in the mask can penetrate at the molecular level. The end result? Healthier, stronger hair from the inside out with added slip and detangling thanks to DAMAGE SHIELD conditioner.

at home

The DAMAGE SHIELD conditioner can also be used at home to protect hair against daily damage. Apply DAMAGE SHIELD shampoo and conditioner at home between K18 mask days to help keep hair healthy and protected through exposure to hair aggressors. Regular application delivers better results at the salon thanks to increased hair health.
