How does K18 work? 

K18 utilizes a breakthrough patented oligopeptide (K18Peptide™) which shuttles amino acids (the building blocks of hair) into the inner structure of the hair. Once inside the hair cortex, the unique amino-acid chain goes directly to the broken disulfide bonds to replace the lost amino acids, regenerating the bond and restoring ultimate strength, resilience and softness.

How do I use the K18 Mask at home? 

 Follow these steps:                    

  1. Shampoo, rinse. Skip the conditioner.
  2. Towel dry hair thoroughly
  3. Apply Mask. Wait 4 minutes. Do not rinse.
  4. After 4 minutes, apply styling products if desired and dry/style as usual.                   

If I don’t color my hair, will K18 be beneficial for my hair? 

We highly encourage it. Our hair is not only damaged by color, but from heat, sun, products, water and environmental aggressors. K18 restores your hairs health and reverses any damage, everyone can benefit from K18.

Is K18 a replacement for conditioner? 

K18’s primary goal is to restore your hairs strength and elasticity by repairing the keratin chains damaged from bleaching, coloring and thermal heat. 

Detangling and conditioning benefits are just an added bonus. As long as you leave it on for 4 minutes, you can add a leave in conditioner, if desired.  If heat styling, it is important to use a heat protectant after the 4-minute processing time.

Why do you skip conditioner?

K18 is most effective on clean, towel dried hair. Conditioner formulas use silicones and conditioning agents that form heavy coatings on hair that prevent K18 Peptide from penetrating to the broken disulfide bonds within the cortex. You may use conditioner after K18 has processed for 4 minutes if needed, not before. 

Why is it important to apply K18 to clean hair? 

We recommend applying K18 to clean hair as products can include oils, silicones, and film formers which will act as a barrier and can alter the efficacy of the product. In severe cases of product buildup, it may be necessary to use a clarifying or detoxifying shampoo for best results so that K18 may penetrate into the cortex. 

Is K18 applied to dry or damp hair?

Always apply K18 to towel-dried, damp hair.

Why do you use K18 Mask on towel dried hair?

K18Peptide™ is not able to regenerate bonds in the presence of too much water inside the cortex. However, the hair needs to be slightly damp to help with penetration of the product into the hair.  

Why do you need to leave the K18 Mask in?

K18 is more effective when left in. The formula is lightweight and works on the inside of the hair, so the hair is left feeling clean and light, even without rinsing it out. 

Can I use styling products with K18?

You can layer styling products on top of K18 Mask after the 4 minute processing time.

What happens if I apply styling products before the 4 minutes after applying K18?

Applying styling products before the 4 minute processing time will diminish the efficacy of K18. 

Can I use K18 every day?

K18 is designed to be used consecutively for 6 washes and then every 3-4 washes to maintain your healthiest hair possible.

Will K18 weigh my hair down?

No, the formula is lightweight and works from within the hair so hair is left feeling clean and light. 

Does K18 wash out of the hair?                        

No, K18’s strengthening and smoothing results are clinically proven to remain in hair, even after repeated shampoos. 

Is K18 considered a protein? 

An extreme amount of protein is only possible when proteins are synthetic. They can be over- used and create build up in the hair resulting in brittle, weak hair. K18 is not a protein treatment. K18 is made up of 13 amino acids which form into a peptide chain nature intended. This technology regenerates the disulfide bond in the hair. 

Can you use K18 on a Brazilian Blowout or a Keratin Treatment? 

We do not recommend using K18 Mist or Mask prior to Brazilian or Keratin treatments. However, we do recommend that you use our K18 Mask on your first hair wash after treatment and for 6 consecutive times after.  

Is K18 Organic? 

K18 is not organic because only natural ingredients can be certified organic. K18 uses both natural and synthetic ingredients because we prioritize cleanliness and safety. 

I noticed there’s alcohol in the formula. Isn’t that bad for my hair? 

In chemistry, the term “alcohol” is used to describe a broad range of organic compounds. Although the ingredients have “alcohol” in the name, they all behave differently and serve different functions in a formula. Many of them are very different in appearance and function from Denatured or Isopropyl (rubbing) alcohol.

Denatured alcohol is used in K18 formulas because it opens keratin’s porous structure and helps deliver the peptide to the hair’s damaged sites.                

Isopropyl alcohol is at a very low level (about 0.5%) in the K18 Mask formula. It is part of an ingredient blend, but it is not directly added to the formulas. It acts as a solvent by making the conditioning agents able to blend into the formulations.

Cetearyl alcohol is a fatty alcohol with a wax-like consistency. It is often used in hair care conditioning formulas because of its smoothing and softening qualities. It does not contain ethanol and therefore is used in products that are marketed as alcohol-free.

Benzyl alcohol is an aromatic alcohol used at 0.5% in the formulas and acts as a preservative. It does not contain ethanol and therefore is used in products that are marketed as alcohol-free. 

I see wheat listed on the ingredient list. Can I use it if I have a wheat allergy? 

Please consult with your physician before using K18 if you have a wheat allergy.  

Is K18 safe to use during pregnancy?
