K18 Damage Shield Protective Conditioner

Conditioning That Protects While It Softens

K18 Damage Shield Protective Conditioner is the partner to the K18 Damage Shield Shampoo and an important part of maintaining K18 results between treatments. It conditions and softens while reinforcing the hair's protective layer, helping prevent the kind of damage that happens gradually from washing, brushing, and environmental exposure. Part of the K18 daily maintenance system for chemically processed or damaged hair.

Best For

• Hair actively using the K18 repair system
• Color-treated or bleached hair needing daily conditioning and protection
• Anyone wanting a conditioner that actively protects rather than just softening
• All hair types needing maintenance between repair treatments

What It Helps With

K18 Damage Shield Protective Conditioner smooths and softens hair while adding a layer of protection to the cuticle to help resist daily damage from brushing, styling, and environmental exposure. It is pH-optimized to work alongside the full K18 system and to not interfere with the repair work being done by the leave-in mask.

How to Use

After shampooing with K18 Damage Shield Shampoo, apply to mid-lengths and ends. Leave on for one to two minutes and rinse thoroughly. Use every wash day.

Pro Tip From Our Stylists

On K18 treatment days, skip the conditioner entirely and go straight from shampooing to the K18 mask. The conditioner is for your regular wash days in between. Using conditioner before the K18 mask interferes with how the peptide bonds to the hair.
