PEPTIDE PREP® detox shampoo

  • A non-stripping, color-safe, pH-optimized lather works to unclog hair follicles while banishing dirt, oils, common metals like nickel, cadmium, lead, zinc, and iron from hard and tap water, and things left behind from heavy product buildup.
  • Intentional formulation means no fillers or deposits left behind leaving the cleanest canvas for maximum K18 molecular repair leave-in treatment results.

leave-in molecular repair hair mask

  • A leave-in treatment mask for all hair types that reverses damage in 4 minutes. Helps to maintain your hair strength and elasticity.
  • Patented K18PEPTIDE™ technology works to repair damage from bleach* + color*, chemical services* and heat*—restoring strength, softness, smoothness, and bounce to hair.

molecular repair hair oil

  • Biotech-engineered weightless oil works on all hair types to strengthen, repair damage, reduce frizz at two levels of the hair fiber, and improve shine.
  • The K18PEPTIDE™ reverses frizz-causing damage long-term at the molecular level. Natural oils work past the cuticle layer to reduce frizz + flyaways, and enhance shine and color vibrancy without weighing hair down.

Begin with detox shampoo

  1. Massage detox shampoo into hair + scalp to remove excess buildup.

  3. Repeat as needed.
  4. Wait to use conditioner until after the mask for optimal repair results.

Apply the leave-in molecular repair hair mask

  3. Let sit for 4 minutes. Do not rinse out.
  4. Apply conditioner if desired for added smoothness, softness + detangling after using the K18 mask, then rinse out.

Finish with the molecular repair hair oil

  1. Apply 1-3 drops of molecular repair hair oil to damp hair, starting at the ends and working upward through the mid-lengths.
  2. Wait 4 minutes. Style as usual.
  3. Apply an additional 1-3 drops of molecular repair hair oil to dry hair as a finisher.

Get started here
Yes, the K18 routine was engineered to deliver your cleanest, healthiest hair for optimal molecular repair results. Before the mask and oil, our PEPTIDE PREP® category tackles every kind of buildup to create your cleanest, healthiest hair canvas. With our molecular repair formulas, you get maximum damage repair plus additional styling benefits with the oil.
No, the detox shampoo will not dry your hair out. This non-stripping formula has a pH of 3.8-4.2 that won’t leave hair over-stripped. In a consumer study, 90%* said hair feels clean without feeling dry. *Disclaimers
The molecular repair hair mask and oil work together to give you the reparative benefits of the K18PEPTIDE™ in both formulas. The oil will add additional frizz-reducing, styling, and heat-protecting properties. You can layer the oil on top of the mask after the 4-minute processing time.
No, the mask will not block the molecular repair hair oil from penetrating. The mask is a highly concentrated treatment without any fillers so it won’t block the oil from penetrating. Like layering different skincare products, the oil can be layered on top of the mask without impacting its performance.
K18 molecular repair + PEPTIDE PREP™ shampoos are formulated with the K18PEPTIDE™. In our molecular repair products, the peptide works at the innermost layers to reverse hair damage. In our PEPTIDE PREP™ shampoos, the peptide helps reduce protein loss to help keep hair feeling healthy and strong.

    Best product for bleached hair

    When I tell you this k-18 molecular hair repair is BY FAR THE BEST PRODUCT ON THE MARKET PLEASE BELIEVE ME. I’ve been getting my hair bleached for the past 7 years and it started getting really dry, brittle and was looking like straw !!My stylist recommended this product . When I saw the price I was a little hesitant but I thought it has to be good if it costs so much and I felt my hair was worth taking a chance on and paying a little extra. As soon as I used it I saw a BIG DIFFERENCE IMMEDIATELY!!! Instant !!!I will never go without this product . EVER!! I wish I had before and after pics so show but unfortunately I don’t so Please take my word you will not be disappointed!!

    It Works!

    I had damage to my hair from bleach, swimming and riding on our motorcycle. I am on a journey to grow out my hair and eliminate the layers. My girl cut as much as she could but my hair was still horrible looking. I had two choices. Cut it all off or try k18. K18 is working!!! My hair looks healthier and smoother each week. I am currently on week 3. This is going to save me a year of growth!
