your protective conditioner questions, answered
can i use the conditioner instead of the mask?

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 between K18 mask days.
*Disclaimers

will the K18 conditioner cause buildup on hair?

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.

will the K18 conditioner weigh hair down?

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.

does the K18 conditioner need to be reapplied for continued UV protection?

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

does the K18 conditioner have SPF?

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*.

    Great shampoo and conditioner for damaged hair!

    I’m really happy with the Damage Shield Shampoo and Conditioner. They leave my hair feeling soft, smooth, and much easier to manage. My hair looks healthier, has a nice shine, and feels less dry after washing. I especially love how they help with frizz and make my hair feel nourished without weighing it down.

    Love love love it.

    This really has saved my hair. It was dry, dull, and just ugly lol. I like that you don’t have to use much. I have long hair that goes to my lower back and its thickness is about medium I guess I would say… this bottle has lasted me almost exactly 6 months. I now only have to wash and condition one a week. It’s helped with oil on my scalp also.

    Moisturized + Protected

    This conditioner keeps my hair silky and manageable. I deal with breakage due to bleach so it’s important that I use a conditioner that strengthens my hair while keeping it moisturized. This is it!
