your protective conditioner questions, answered

still have questions? visit our help center

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*.

Reviews Summary
Customers say this conditioner makes their hair feel incredibly soft, smooth, and manageable without weighing it down. Many report noticeable improvements after just one use, with hair becoming less frizzy, more detangled, and easier to comb through. Users with fine hair appreciate that it doesn't leave hair feeling heavy or greasy, while those with thick, curly, or damaged hair find it provides excellent moisture and slip. Many mention the pleasant scent and how it works well with the matching shampoo. Frequent comments address how it helps with breakage, split ends, and overall hair strength, with several noting their hair appears thicker and shinier over time.

    So good - get the big one

    I did the smaller bottles first to try it out. A little shampoo goes a long way but I need more conditioner so I’d suggest the small shampoo and the big conditioner and you’ll run out around the same time.

    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!
