Strengthening, smoothing hair oil works on two levels of the hair fiber to fight frizz.

The K18PEPTIDE™ works to address deeper-level damage that causes frizz—repairing and strengthening damage at the innermost layer of hair to reverse damage that leads to frizz.

On the surface of hair, natural oils like avocado and sunflower oil, and hemisqualane and squalane nourish while smoothing frizz + flyaways to improve color vibrancy, enhance shine, and provide 450°F (232°C) heat protection.

  • Clinically proven to repair damaged hair*
  • 24-HR frizz control*
  • 104% increase in shine*
  • 78% reduction in split ends*
  • 450°F (232°C) heat protection*

*Disclaimers

This silicone-free oil fights frizz differently by addressing the damage that causes frizz long-term and immediately smoothing frizz + flyaways.

  • Reverses frizz-causing damage: Works at the molecular level to repair damaged hair, which is more susceptible to frizz
  • Reduces frizz + flyaways: Natural oils work on the surface of the hair to smooth the cuticle + soften without weighing hair down
  • Enhances shine + color vibrancy: Nourished, moisturized hair reflects higher shine and boosts color dimension
  • Delivers heat protection: to prevent further frizz-causing damage up to 450°F (232°C)

Apply to damp, towel-dried hair before styling, or on dry hair as a finisher. Highly concentrated formula. Start with 1-3 drops and build as needed.

Use on damp hair for: strengthening benefits and to reduce frizz during air-dry or styling

Use on dry hair to: smooth frizz and flyaways, as a finisher to add shine

For Stylist Use

Begin with PRO chelating hair complex:

  1. Section dry hair into 4 quadrants.
  2. Apply 6-10 sprays of K18 pro chelating hair complex per quadrant*.
  3. Wait 4 minutes after chelating (do not rinse out)

Apply the PRO molecular repair hair mist:

  1. Apply a minimum of 10 full sprays of K18 professional molecular repair hair mist to each quadrant, increasing up to 20 sprays per quadrant as needed, depending on client’s length, density, and level of damage.
  2. Wait 4 minutes (do not rinse out). If needed, dry the hair prior to applying lightener or color. Then perform your desired technique.

Apply the PRO molecular repair hair mask:

  1. Shampoo (do not condition) and towel dry thoroughly.
  2. Apply 1-3 pumps of K18 professional molecular repair hair mask based on your client’s length and density, starting at the ends and working up towards the roots.
  3. Let sit for 4 minutes (do not rinse out).

Finish with the molecular repair hair oil

  1. Apply 1-3 drops of K18 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 K18 molecular repair hair oil to dry hair as a finisher.

*For cases of extreme metal + mineral buildup, process up to 10 minutes, then proceed with the instructions.

**For best results, we recommend to use K18 chelator before every service. If not using K18 chelator, lightly dampen hair with water (do not saturate) before applying K18 PRO mist.

Pro Tip - If using the K18 molecular repair mask, apply the mask first on clean, damp hair, then wait 4 minutes. Apply the molecular repair hair oil, and wait 4 minutes for maximum strengthening results.

Highly concentrated formula. Start with 1-3 drops and build as needed.

Description

This 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.

got questions?

Get started here.

Yes, the molecular repair hair oil works on all hair types.

Yes, this oil provides heat protection up to 450°F/232°C.

No, the mask will not block the molecular repair hair oil from penetrating. The mask is a highly concentrated treatment without any fillers that would block the oil from penetrating. Like layering different skincare products, the oil can be layered on top of the mask without impacting its performance.

No, it will not leave buildup or weigh down hair. This weightless oil is powered by intentional ingredients to reduce frizz-causing damage on the molecular level inside the hair fiber, while natural oils work on the surface of hair without weighing it down.

Plus, you don’t need much of this highly concentrated formula to see results, just use 1-3 drops and build as needed. If you or your clients are concerned about buildup, use our detox shampoo to remove 99% of product buildup after just 1 wash*.
*Disclaimers

Instead of mixing the oil and mask together, get the most effective repair and styling benefits by using the mask first, waiting 4 minutes, and then applying the oil.

how to use + sell it

PRO stylist + educator Carly Zanoni shows you how to use the molecular repair hair oil to strengthen and smooth your hair + your client’s.
PRO stylist + educator Eric Vaughn chats his favorite things about the molecular repair hair oil + why every client needs it.

plays well with others

The molecular repair hair oil works on its own and can be paired with the K18REPAIR™ service.
what's the difference?
Think of the K18REPAIR™ service as damage repair treatments used before and after services. The oil is for smoothing, styling, and strengthening after the mask, and can be used on damp and dry hair.
why wouldn't I just use the oil?
We recommend using the oil with the K18REPAIR™ service to get maximum molecular repair results with additional styling benefits.
when would I use both?
Use the K18REPAIR™ service pre and post-salon service to reverse hair damage in 4 minutes. You can layer the oil on top of the mask after the 4-minute processing time for additional frizz-reducing, styling, and heat-protecting properties.

It works!

It gets rid of any frizz and with the mask makes my hair soft and manageable. I use it after the mask sets on my hair for 4-5 minutes. And use it on the bottom 1/3 of my hair. I’ve also used it throughout my hair and it doesn’t make your hair look greasy.
