step 1: shampoo

K18 DAMAGE SHIELD pH protective shampoo  makes an ideal everyday cleanse to remove dirt and oils. If your hair’s feeling heavy and sticky, go for K18 PEPTIDE PREP™ detox shampoo, which was engineered to remove 99% product buildup*, 95% sebum*, and 76% copper* with every wash. 

step 2: molecular repair

You know what works on every single hair type? Hair repair on the molecular level. That’s because at the molecular level, all hair is the same. K18 leave-in molecular repair hair mask is our most-loved product for a reason; no matter your damage level, this peptide-powered treatment reverses damage in just 4 minutes. You’ll use this highly concentrated leave-in on clean, damp hair. That means you’ll shampoo, skip the conditioner, and apply 1-3 pumps of the full-sized K18 mask (3-9 pumps of the mini K18 mask). That’s it! After waiting 4 minutes, you’re ready to start styling. 

How often to use K18 molecular repair mask? Some use it as a damage repair treatment every wash. Others use the mask for the first 3-4 washes when damage or breakage appears. 

step 3: styling + frizz control

K18’s newest molecular repair hair oil is our team’s favorite for immediate + long-term frizz fighting, 450°F (232°C) heat protection*, and clinically proven damage repair*. Meaning you can double up on molecular repair while safely styling. 

Apply it on damp hair before using hot tools, on dry hair to amp up the shine and control frizz, or both. However you incorporate this highly concentrated oil, start small with 1-3 drops, working your way up as needed.
