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

    Nice!

    Tried the K18 DAMAGE SHIELD shampoo + conditioner samples and honestly loved them. My hair felt super soft, smooth, and lightweight after just one wash. The shampoo cleans well without drying, and the conditioner made my hair look shinier and less frizzy. Also, the scent is really nice and fresh. Definitely considering buying the full sizes!

    First time buying k18

    This is my first purchase of k18 and I wanted to order directly from the website so I knew I was getting the correct product and not some knockoff. After looking at reviews on how to use it properly, I have used it twice so far and what a difference in my hair. I've really damaged hair from highlights. And as I was sitting one day I noticed my hair just looked like a stack of hay. It is so much better now and when I just recently went back for for highlights by hair stylist was like your hair looks so healthy. I told her I was using k18 and she said that's what they use at their salon as well. So I knew I was on to something.

    We love that you chose to order directly from our website to ensure you got the authentic product, and it's so exciting to hear that your salon uses k18 too - you definitely know you're on to something great!
