Keratin treatments are the celebrity secret to straight, smooth, and frizz-free hair. So when your clients come in wanting the same look, you may wonder if K18 works with this service. The answer? Yes! Here’s how:

Start with the K18 PEPTIDE PREP™ pro chelating hair complex to reduce metal + mineral buildup for optimal service results. After 4 minutes, go in with the K18 professional molecular repair hair mist to fortify hair pre-service, restoring up to 99% elasticity* before the damaging keratin treatment. For added softness, shine, and heat protection, use the K18 molecular repair hair oil on dry hair post-service.

My PRO tip—wait to use the K18 molecular repair hair mask 3-4 shampoos AFTER the keratin treatment. This gives time for the temporary coating of the keratin treatment to wear off, so your clients get the full benefit of the reparative K18PEPTIDE™ delivered into the hair.

why do you need K18 before keratin services?

Imagine a keratin treatment as a sealant for hair, like laminating a crumpled document into a smoother, straighter version. Using K18's PRO mist first is like repairing any tears in the document before laminating it, so you get a better end result. This K18-patented molecular repair technology reverses damage in just 4 minutes*—without having to change your formulas or service steps. Its lightweight formula isn't bogged down with heavy emollients either, making it ideal for this service.

I’ve seen the difference firsthand, using the PRO mist on a client that I had previously done a treatment on. Many keratin treatments require many passes of a flat iron at high heat, which can cause a lot of stress and damage to hair. The PRO-exclusive spray improves hair’s resilience to prevent damage during and after services* for stronger hair over time*. That’s why my client’s hair didn’t feel fragile while smoothing and flat ironing it.

aftercare matters

The journey to sleek hair doesn't end with the treatment itself. Haircare at home plays a pivotal role in ensuring that your clients’ keratin-treated hair continues to shine. Here are my PRO tips to share with your clients:

use a sodium chloride-free shampoo

Sodium chloride in some shampoos can dissolve the keratin treatment, so it wouldn’t last the average 2-4 months that keratin treatments usually last. Extend the longevity of their results with a sodium chloride-free shampoo that’s optimized for hair’s pH levels. This minimizes cuticle swelling to prevent moisture loss—keeping hair smooth and clean without drying out hair.

molecular repair for ongoing damage repair

Prioritizing molecular repair at home is super important to repair any daily damage, and of course the effects of the damaging chemical + heat service. Wait to use the K18 mask until after the first 3-4 shampoos to maximize the benefits of the mask, as the keratin coating temporarily prevents deep penetration.

prevent heat damage with K18 oil

Send your clients home with the K18 oil for heat protection and a softer mane. Plus, it adds shine without weighing their hair down.

Now you know why K18 PRO mist and keratin treatments are a match made in haircare heaven. The innovative damage repair technology creates a stronger, more resilient canvas to create on. So go ahead, realize your clients’ hair goals without compromising their hair health.
