have questions?

Get started here

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

K18 Damage Shield, Protect's!

It was amazing on the hair to comb tangle free, having natural curly hair it enhanced the volume, shine and coiled curls. After a few days I used a curl wand to change the style and amazing results lasting two more days!!! Game changer......8)

Great for overprocessed hair

After using the damage shield just once, I immediately noticed that my hair dryer quicker. Thats perfect to help save my hair from heating elements. I didn’t notice as many fly away hairs on the top of my head. It appeared smoother, more tame. I would recommend this product to my friends who use a lot of irons and heat in their style.

Mixed feelings

I have mixed feelings about the conditioner. Some of my client's hair felt worse after using it. I followed K18 mask with the Protective Shield and it felt more tangly and less smooth than using K18 alone. On other's hair, I didn't see much difference. I even tried using it without K18mask and it was adequate. My ultimate review is that I don't see a need for it. I'd rather just use K18 mask because the hair feels smoother and improved immediately. Now I can't speak for the results of "3 days of environmental/heat/etc protection." But I do like the idea of that. I'm heavy hearted to give this feedback because I love every single other product from K18 and I use them exclusively in the salon and on myself.
