Parabens, Sulfates, Silicones, Phthalates, Sodium Chloride, Artificial Colors, Formaldehyde and Formaldehyde Donors.

Is K18 vegan & cruelty-free?

Vegan, Cruelty-Free, Color-Safe, and Dermatologically Tested.

What is the K18PEPTIDE™?

Our biomimetic peptide mimics hair’s natural structure to seamlessly fit in and reconnect broken keratin chains responsible for hairs core strength and elasticity. As a result of this reconnection it also addresses cleaved disulfide bonds for connection along the Y-axis of hair AND the x-axis or width of hair.

What is the K18Peptide ™ patent number?

EP3058936A2

Is the K18PEPTIDE™ in every K18 product?

All K18 products 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™ products the peptide acts like a protective shield at the cuticle level to mitigate protein loss that can come from washing.

What is biomimetics?

Biomimetics is a fancy way of saying “learning from and mimicking nature.” By mimicking the natural structure and molecular makeup of keratin proteins, the K18PEPTIDE™ is the perfect puzzle piece to connect broken keratin chains to renew strength + elasticity.

Is K18 a bond builder?

Nope. Instead of temporarily restoring just one type of bond, K18’s biomimetic peptide mimics the molecular makeup of keratin to reinforce strength along the length AND width of the hair fiber. Bond builders walked so we could run, ya know?

What is the K18 PRO service?

The K18 PRO SERVICE is an in-salon exclusive that reverses hair damage in 4 minutes. The patented peptide technology works to repair damage pre + post service from bleach, color, chemical services, and heat restoring strength, softness, smoothness, and bounce to hair.

How does the Pro Service work?

It’s super simple, both formulas have our biotech-powered peptide, so by using both one on top of the other, you’re doubling down on the peptide for maximum damage repair. The K18PEPTIDE reverses hair damage in 4 minutes by reconnecting breaks in the hair fiber along both the length (keratin chains) and the width (disulfide bonds) for wholistic hair renewal

Who is K18 for?

K18 is engineered to work with every hair type, in every service, and with every routine.

What is the PRO mist?

Peptide-powered lightweight mist engineered to strengthen hair’s defense against damaging chemical services. pH level of 7.5-8.0 shifts the cuticle layer open to penetrate hair’s cortex and deliver the K18PEPTIDE™ to damage sites on the molecular level.

What are the PRO mist ingredients?

Water (Aqua) (Eau), Alcohol Denat., Propylene Glycol, Polysorbate 20, sh-Oligopeptide-78 (K18PEPTIDE™), Hydrolyzed Wheat Protein, Hydrolyzed Wheat Starch, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Phenoxyethanol, Potassium Sorbate, Potassium Hydroxide, Fragrance (Parfum), Geraniol, Linalool, Hexyl Cinnamal, Benzyl Alcohol.

Why is the PRO mist used before chemical services?

K18’s PRO mist is typically used before chemical services to set clients up for success, renewing existing damage for the strongest canvas to create on. In cases of extreme damage or fine hair, the PRO mist renews hair without weighing it down.

Why do I mist hair with water before using the PRO mist?

Water will swell the cuticle layers to open up the hair fiber and allow for maximum penetration of the PRO mist into the innermost layers of hair. In the same way a damp sponge absorbs more water, damp hair absorbs K18.

How do I use the PRO mist?

- Before all professional and chemical services, mist hair with water (do not saturate).
- Section hair, apply PRO Mist generously, section by section. Work into hair.
- Let sit for 4 minutes to activate. Do NOT rinse out.
- Dry hair and process as usual.
- Shampoo, do not condition.
- Towel-dry thoroughly.
- Continue treatment with K18 Mask. Follow our service guide for specifics.

How much mist do I use?

You can go crazy with the mist, don’t be afraid. Make sure that hair is covered with a generous amount.

What is the K18 mask?

Peptide-powered treatment to repair damage from bleach + color, chemical services, and heat. pH level of 5.0–6.0 helps close down the cuticle to seal in the K18PEPTIDE™ for renewed strength + elasticity.

What are the K18 mask ingredients?

Water (Aqua) (Eau), Alcohol Denat., Propylene Glycol, Cetearyl Alcohol, Dicaprylyl Ether, Cetyl Esters, Behentrimonium Chloride, Polysorbate 20,sh-Oligopeptide-78 (K18PEPTIDE™), Hydrolyzed Wheat Protein, Hydrolyzed Wheat Starch, Isopropyl Alcohol, Tocopherol, Phenoxyethanol, Potassium Sorbate, Citric Acid, Fragrance (Parfum), Geraniol, Linalool, Hexyl Cinnamal, Benzyl Alcohol.

How much mask do I use?

Less is more, so don’t overdo the K18 mask. This highly concentrated formula was made to use way less than your traditional hair mask or conditioner. Start with 1 ml, warming it up in your hands to help evenly distribute + use less. Add 1/2 pump more at a time to encounter any missed strands (average use is 2 pumps, on the highest end the thickest or most curly–coily hair uses a maximum of 3 pumps).

Is the K18 PRO mask and take-home mask the same?

Yes, both formulas are the same. The PRO mask is conveniently sized for PRO use.

Why skip conditioner?

Conditioner leaves a film that blocks our peptide from penetrating effectively. Once the 4-minute wait time is up, feel free to use a conditioner a leave-in, or any type of product.

Does K18 replace conditioner?

Think of K18 as a highly concentrated treatment. It restores hair’s strength + elasticity in the innermost layers of hair, instead of traditional conditioners that coat the outside of hair. After the 4-minute wait time post-K18, feel free to add a leave-in for a boost of conditioning if needed.

Why do I use K18 mask on towel-dried hair?

Water in damp hair swells the cuticle (the outside layer of hair) to open the gates for our biomimetic peptide to enter and travel to the innermost layers of hair. If the gates aren’t open, the product will stay on the surface—giving you mostly superficial repair. By applying on damp hair, you can use less, waste less, and still get the best results.

Is K18 considered a protein?

K18 is not a protein treatment, our biomimetic peptide naturally mimics the amino acid sequences in keratin to rebuild bonds broken by chemical, color, and heat damage. If you are experiencing dry, brittle hair, try a detox shampoo to remove buildup.

Why is there alcohol in the formula?

We like to keep our formulas minimal, only using the exact amount of ingredients needed to get the peptide where it needs to go. Here the alcohol serves as an agent to optimize the hair environment for K18 to work on a deeper level. Our unique blend of 3 alcohols function to open the hair cuticle so the K18PEPTIDE™ can penetrate the innermost layer of hair, reaching the broken polypeptide chains (keratin chains).

How do my clients use K18 at home?

IN the shower
- Shampoo, do not condition. If you're a heavy product user, use K18’s PEPTIDE PREP™ detox shampoo.

OUT of the shower
- Apply to damp hair that feels wet to the touch, but isn’t dripping water.

- Start with 1 pump and spread it between your hands. Work evenly from ends to roots.

- Only add 1/2 pump more at a time to encounter any missed strands (average use is 2 pumps, on the highest end the thickest or most curly–coily hair uses a maximum of 3 pumps).

- Let sit for 4 minutes to activate before combing + styling. Do NOT rinse out.

- After the 4 minutes is up, style as usual—you can rewet your hair, add a leave-in, blow-dry, you do you.

How often do my clients use the K18 mask at home?

Start by using K18 after the first 4-6 washes. Then switch to maintenance mode for a boost of renewed strength, softness, smoothness, and bounce when needed. In the case of extreme damage, use K18 after the first 4-6 washes again.

How do I use PRO mist + mask together in a service?

Here’s how to use the K18 double dose treatment:
- Cleanse with K18 detox shampoo for the cleanest canvas
- Towel dry thoroughly
- Apply K18 PRO mist generously
- Immediately apply K18 PRO mask on top (remember it’s highly concentrated so only use about 1-3 pumps)
- Wait 4 minutes
- Style as usual (you may add additional products at this time)

How do I use K18 + toner?

After using the K18 mask, apply toner or gloss on top, and process as required. Rinse, shampoo, and towel dry thoroughly, then follow with a secondary application of the K18 mask.

Will using toner on top of K18 Mask affect my color?

K18 will not interfere with toner or final color. Colorists tell us K18 Mask delivers a more uniform, and vibrant color application, as it evens out the hair’s porosity and damage.

How do I use K18 + cut or style

You can begin cutting immediately after applying the K18 PRO service. Just wait 4 minutes before adding additional styling products or cutting lotions.

How often should I use K18 on a client?

We recommend using the K18 PRO service every time your client visits to strengthen their hair canvas + reverse in-salon damage for stronger, softer, smoother, bouncier hair. Even if your client is not undergoing a chemical service, K18 can maintain their hair integrity from ongoing damage.

Why should my client use K18 at home?

Damage is ongoing out of the salon, so your clients' use of K18 should be too. With a healthy hair base, services last longer, and you can go further in their next appointment. Best part, the K18 mask comes in 3 retail sizes to cover all kinds of client beauty budgets.

Can I put PRO mist + mask directly in my chemical services?

K18 is meant to strengthen and protect hair before and after chemical services, so there’s no need to alter your services.

Is K18 safe to use during pregnancy?

Although K18 is free of sulfates, parabens, phthalates, silicones, artificial colors, sodium chloride, and is vegan and cruelty-free, we recommend clients consult their doctors before using K18 during pregnancy or if they have concerns about allergies. We are happy to provide an MSDS sheet.

What if my client has a wheat allergy?

K18 PRO mist + mask do contain a small amount of wheat protein. Please consult your doctor before using K18 if you have a wheat allergy, and conduct a patch test upon approval to test for any allergic reactions.

Will K18 work on hair with a lot of buildup?

Any type of coating whether it’s product buildup, sebum/oil buildup, or even mineral + metal buildup from hard water can block our biomimetic peptide from getting where it needs to go. We recommend a detox shampoo prior to K18 application for first time users, or people that use a lot of styling product to clear the path for our peptide to fully penetrate hair.

Can I use styling products with K18?

Yes, K18 is compatible with all styling products.

Can I use a built-in bonder lightener with K18?

Yes, K18 is compatible with all professional products

Can I use all hydrogen peroxide with K18?

K18 products provide all the great conditioning and acidic balancing results of anacidic toner. They can be added as an additional step before toning for even morebenefits.

Will alkaline hair color affect the performance of K18?

Alkaline hair color swells the hair’s cuticle layers and throws pH level off balance.Using K18 before and after these services will help to calm the hair environment,bringing the pH closer to hair’s optimal levels.

Why is clean hair important?

Hair happiness starts with the cleanest hair possible. With a clean base, hair color applies more vibrantly, K18 treatments perform more effectively, and styling products work better.
