clean streak minis

Limited-edition 3-step mini set cleans, protects + refreshes all hair types.

Description

This mini routine gently cleanses, protects hair from damage, and keeps your hair feeling fresh for up to 3 days*.

**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

The DAMAGE SHIELD pH protective shampoo delivers healthier hair and scalp after just one wash.

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*.

    Worth it!!

    Before and after pics of me trying to do a curly perm even though I already had curly dyed hair. It completely destroyed my hair.

    I decided to cut it off and start over. It's growing back so fast and it feels so much healthier. I bought the detox shampoo, hair oil, leave in hair mask and Damage Shield shampoo/conditioner. I know it's expensive but it is worth every penny

    Hair, Refreshed

    I received my order today and couldn't wait to try AirWash! I'm on day 4 hair and it started to lift and separate into frizz on top and oily, piecey parts underneath. I have shaken well, sprayed and massaged in as directed. I am so pleased with the results! First, the fragrance is so good! I have volume restored and a more even texture throughout the head. The shine isn't dulled. There's no residual sticky feeling after application and brushing. My hair feels refreshed! I'm hoping to get 2 more days from this application.

    We love hearing how AirWash transformed your day 4 hair! It sounds like it delivered exactly what you needed - restoring volume, evening out texture, and keeping that natural shine while eliminating any sticky residue. Thank you for sharing your experience, Erinn!

    LOVE!

    The Damage Shield protective conditioner has become my favorite conditioner! My hair feels so soft, NOT tangled, and clean after! I have A LOT of THICK and BLEACHED hair so not every conditioner works for my hair. I have noticed an improvement in my hair health, shine, and shedding since the combined use of K18 products. 10/10 recommend this conditioner!
