Protection you can feel, not weight you can't get rid of
Most conditioners fix how hair feels today. DAMAGE SHIELD works one step earlier — it strengthens the hair's outer defenses so daily wear does less harm in the first place.
The concentrated gel-cream texture melts through mid-lengths and ends, releasing slip on contact so knots fall out without tugging. What's left behind is softness and shine — never a heavy, coated film.
Three sources of damage, one shield
Hair takes a beating you rarely notice: UV exposure on the walk to work, friction from brushing and hot tools, pollution and hard water. DAMAGE SHIELD is clinically proven to deliver conditioning protection against all three for up to 3 days,* so protection carries you between washes.
What's inside
-
K18PEPTIDE™ — replenishes protein that washing strips away, keeping strands resilient rather than hollow.
-
Biotech-produced polysaccharide — forms a biomimetic barrier against pollution and environmental stress before damage happens.
-
Fortifying ceramide blend — seals damage sites along the cuticle for smoother, stronger, shinier hair.
-
pH-optimized formula — limits excess cuticle swelling during washing, which is where dullness and roughness begin.
-
No film-forming silicones or waxes — nothing that builds up, dulls color or drags fine hair down.
Clinically proven results*
- 3 days of conditioning protection from UV, mechanical styling + environmental aggressors
- 94% agreed hair didn't feel weighed down
- 91% agreed hair felt softer
Best for
Color-treated, bleached, heat-styled and generally overworked hair. Safe for all hair types and textures, including fine hair that usually can't handle a conditioner. Color-safe.
How to use
- After shampooing, work a small amount from mid-lengths to ends. Start with less than you think — the formula is concentrated — and build if needed.
- Rinse thoroughly.
- Best paired with DAMAGE SHIELD pH Protective Shampoo. On repair days, use your K18 leave-in molecular repair mask first, wait 4 minutes, then follow with conditioner for extra slip.
FAQ
Can this replace the K18 leave-in mask?
No — they do different jobs. The mask reverses existing damage in 4 minutes; the conditioner protects against new daily damage. Use them together.
Will it build up or weigh hair down?
No. There are no film-forming silicones or waxes, and the concentrated gel formula means a little goes a long way.
Does it contain SPF?
No. The polysaccharide and ceramide blend reduce the drying, roughening effect UV has on the cuticle — that's hair protection, not skin SPF.
Do I need to reapply for UV protection?
No. Protection lasts up to 3 days per application.*
