What It Is

A nourishing, protective conditioner that helps shield hair from daily damage to help maintain hair health and improve smoothness and shine. Engineered to weightlessly soften and detangle while the K18Peptide™ helps replenish hair during washing.

What It Does

• Clinically proven to provide conditioning protection against damage from UV rays*, mechanical styling**, and environmental aggressors*** for up to 3 days.

• Maintains hair health: Fortifies hair’s exterior lipid barriers to make hair more resilient and resistant to damage. K18Peptide™ replenishes protein lost during washing.

• Enhances hair’s natural shine: pH-optimized formula minimizes excess cuticle swelling during washing, to help keep hair smooth and maximize shine.

• Softens, smooths, and detangles: Without film-forming silicones or waxes that can build up over time, weighing hair down.

 

*81% breakage reduction observed on bleached hair tress with repeated grooming after 50 cycles of UV and wash exposure versus tress without K18 conditioner.

**UV and mechanical damage results observed with repeated grooming on hair tress after a simulated 3 days of UV exposure, versus tress without K18 conditioner.

***Environmental aggressors results observed on hair tress after a simulated 3 days of pollution exposure, versus tress without K18 conditioner.

What Else You Need to Know

• Biotech-produced polysaccharide acts as a biomimetic shield to protect hair against pollution and environmental aggressors.

• Fortifying ceramide blend seals damage sites in the hair cuticle—smoothing and protecting hair from further damage.

• K18Peptide™ replenishes protein lost during washing.

Rated 3 out of 5 by from I hate to say this didn't work for me :/ I have bleached healthy hair and after using this my hair felt dryer and frizzier after getting out the shower. I tried it twice with a different hair mask and still was dry. I'm so sad
