Wait 4 minutes, then apply 1-3 pumps of K18 professional molecular repair hair mask based on your client’s length and density, starting at the ends and working up towards the roots. If you’re using the PEPTIDE PREP™ pro chelating hair complex, there’s no need to mist the hair with water before using the PRO mist. Wait 4 minutes after chelating** (do not rinse out), then apply a minimum of 10 full sprays of K18 professional molecular repair hair mist to each quadrant, increasing up to 20 sprays per quadrant as needed, depending on client’s length, density, and level of damage.

It’s powered by our biomimetic K18PEPTIDE™ to seamlessly fit in and reconnect broken polypeptide chains at the molecular level. The K18PEPTIDE™ powering both formulas reverses damage from bleach* + color*, chemical services*, and heat* in 4 minutes. For best results, use for the first 4-6 consecutive washes, then every 3-4 washes as needed to maintain hair strength.

Many products with the Premium Beauty badge are also used by professionals in salons and spas but are designed and available for home use.

Do not use conditioner, towel dry hair thoroughly, apply Leave-In Molecular Repair Mask and wait 4 minutes. K18 strengthens hair’s core structure, restoring damaged curl patterns and leaving strands looking and feeling like new. I have damaged blonde hair that dreads itself when it’s wet so to skip conditioner to apply this makes it a real mission to brush through and apply! My curly hair seems a lot less frizzy and still soft by thr end of the end and the days I don't wash I'm not completely dried out and knotted.We recommend misting hair with water before using the PRO mist to swell the cuticle layers and open up the hair fiber, allowing for maximum penetration of the peptide-powered PRO mist into the innermost layers of hair.

As a result, disulfide bonds are also reconnected for reinforced strength along the length + width of hair—offering comprehensive, lasting, and progressive repair. If your clients are experiencing dry, brittle hair, use PEPTIDE PREP™ detox shampoo pre-K18 mask to remove buildup.Begin with 1 pump of the K18 Mask and add more as needed depending on the length, thickness, and condition. PRO tip: When working on clients with tape-in extensions, we recommend following the standard protocol for cream-based conditioner or oil usage.
