What makes the DAMAGE SHIELD pH protective shampoo special?

The DAMAGE SHIELD pH protective shampoo delivers healthier hair and scalp after just one wash. Its optimized pH helps maintain the hair cuticle, preventing excess water from entering the hair, which can cause damage, dullness, frizz, and tangling. With this shampoo, your color is maintained, hair feels strong, healthy, looks smooth with less frizz, and is easier to style with less tangles. This formula moisturizes hair without weighing it down, and preserves the scalp microbiome for a healthier-feeling scalp and a gentler cleanse. Coupled with the DAMAGE SHIELD protective conditioner, these formulas shield your healthiest hair from daily damage.

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

When do I use the DAMAGE SHIELD pH protective shampoo?

This pH-balanced formula is gentle enough to use every time you cleanse, delivering healthier hair and scalp after just one wash.

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.

smooth + shield all hair types

pH-optimized formula prevents frizz, dullness + tangles for everyone.

    Tried the sample and immediately hit BUY!

    I’m rehabbing some over processed hair and also dealing with some fallout from surgeries in the fall. I ordered the treatment first and with it came these samples. One try and I had to buy!

    Miracle worker

    I've been bleaching my hair on and off for 20 years. I've spent more than I'd like to admit on products to smooth and treat my hair for all the damagei have from said bleach as well as all the heat i use on it. I have naturally wavy hair that is a bit poofy and frizzy. I straighten almost every time I wash. Nothing has ever worked like K18. After I put it in my hair, I blow dry and straighten as usual and my hair looks so incredibly smooth and healthy. This stuff is amazing. Well worth the price.

    WOW

    This shampoo and conditioner really made a difference in my hair. It looks smoother and healthier and brought back to life! I did one side with the k18, and the other with another luxury brand I use, and the results speak for themselves.

    Improved hair health and new growth

    My hair was fried after going lighter this summer. I’ve been using K18 products for about 4 months. I definitely have seen an improvement in the overall heath of my hair along with new growth in areas that were previously extensively damaged
