Get started here

The mask and conditioner serve two different purposes. The K18 mask reverses damage in 4 minutes, while the K18 conditioner protects hair from daily damage for up to 3 days*. We recommend using the K18 mask first, waiting 4 minutes, then using conditioner for additional softening and detangling benefits in the salon, or at home between K18 mask days. *Disclaimers

No, the K18 conditioner will not cause buildup on hair. The highly concentrated, lightweight gel formula means a little goes a long way. Use less than you typically would with a traditional conditioner, and build as needed.

No, the K18 conditioner will not weigh hair down. This highly concentrated, lightweight gel formula softens, smooths, and detangles without film-forming silicones or waxes that can build up over time.

No, you do not need to reapply the K18 conditioner for continued UV protection. This product is clinically proven to protect hair against damage from UV rays for up to 3 days*. *Disclaimers

No, the K18 conditioner does not have SPF. The biotech-produced polysaccharide and fortifying ceramide blend help minimize the drying and damaging effects of UV rays on the hair's cuticle. This prevents hair from becoming rough, brittle, weak, and prone to breakage from UV damage for up to 3 days*. *Disclaimers

3-day damage protection, powered by biotech

why hair needs a shield

Damage happens every day from UV rays, mechanical styling, and environmental aggressors, weakening, dulling, and causing frizz on all hair types.

how the shield works

Protect hair BEFORE daily damage occurs. Inspired by nature’s resilience to harsh environments, our biotech-produced polysaccharide delivers 3-day conditioning protection without reapplying.

expert-approved protection

Trichologist Angela Onuoha breaks down how common hair aggressors damage hair, and how DAMAGE SHIELD protects hair between K18 mask days.

It works!

I love this conditioner. It left my hair detangled and soft. My hair has changed since it turned gray. It became frizzy, curly, and unmanageable. Now it looks great and is easy to style.

I love K18

Using Damage Shield Protective Conditioner along with the Damage Shield Protective Shampoo consistently results in perfectly moisturized soft waves and curls that do not need a lot of styling products. A little product goes a long way. Love all the K18 products.
