**Clean streak minis work with hair’s biology to deliver soft, strong, smooth, bouncy hair for every hair type, color, texture + style. **

DAMAGE SHIELD pH protective shampoo:

  • Safe but powerful cleansing: Plant-derived surfactants deliver safe but effective high-power cleansing to break down and remove dirt + oil
  • Designed for damaged hair: pH-optimized formula helps prevent excess swelling of the hair cuticle during washing—which helps maintain color, improve hair health and shine, and reduce frizz

  • Enhances hair’s natural shine: pH-optimized formula minimizes excess cuticle swelling during washing to help keep hair smooth and maximize shine
  • Softens, smooths, and detangles: Without film-forming silicones or waxes that can build up over time and weigh hair down

AirWash™ dry shampoo:

  • Absorbs oil: made with translucent microbeads to absorb excess oil without visible starchy buildup, or white cast
  • Eliminates odors: odorBIND™ smart-release biotechnology recognizes, traps and eliminates odor-causing molecules, and replaces odors with a subtle fragrance for a clean, fresh feel, for up to 3 days*
  • Supports a healthy scalp: helps balance scalp sebum to promote scalp health between washes, minimizes excess buildup

This pH-balanced formula is gentle enough to use every time you cleanse, delivering healthier hair and scalp after just one wash.
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.
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.
No, AirWash™ will not leave buildup or white cast behind. It’s formulated with translucent microbeads to absorb oil without leaving starchy buildup or a visible white cast behind*.
No, it will not disturb your style. In a consumer test, 93% agreed the product did not revert their hairstyle*.

    Great recommendation from my stylist

    My stylist told me that K18 was the best on the market. I ordered it and have been using it for a few weeks now. I can already tell my hair is stronger and feels healthier. Less frizzy when it air dries. I'm a loyal customer now!

    Thoroughly Impressed

    This conditioner is easily one of the best that I’ve used. It’s slightly heavy but that is to be expected considering what it does. I have fine, wavy, color treated, hair and it doesn’t weigh it down too much nor does it feel oily faster. Would recommend!
