have questions? we have answers
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 in the salon, or at home 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*.*Disclaimers
