What is keratin?

Keratin is a protein found naturally in skin, hair and nails, in addition to other sources. In human hair, it acts both as an external protective shield and an internal structural protein. Keratin is the first thing depleted when hair is damaged physically, chemically or from environmental factors such as the sun.

What does keratin do?

Keratin Complex’s signature keratin is comparable to the keratin present in human hair. When used in product formulations, keratin helps condition, strengthen, revitalize and repair damage. Keratin gives the hair shine, elasticity and a more youthful, healthy appearance.


What causes frizz?

Healthy hair contains proteins (including keratin), water and lipids that work to moisturize and keep strands strong and smooth. With age and damage due to sun and environmental exposure, the hair loses some of these vital components, making it drier and more porous. To compensate, the hair absorbs excess moisture from the air (especially in high-humidity environments), causing the cuticle to swell and thus, producing frizz.

Keratin Complex products and services replenish keratin to help seal the cuticle and prevent humidity from entering the hair.

Smoothing Therapy Treatments

What is a Smoothing Therapy treatment?

Keratin Complex Smoothing Therapy treatments are professional smoothing treatments powered by our signature keratin. All treatments are performed in-salon by a professional stylist. Smoothing Therapy treatments repair damage and breakage, reduce frizz, curl and unruly flyaways, and make the hair smoother and healthier-looking. They also prevent humidity, the main cause of frizz, from impacting the hair. After a Smoothing Therapy treatment, it’s easier to achieve a flawless blowout at home: The hair is more manageable, blow-drying becomes quicker and easier, and daily styling time is significantly reduced.

What in-salon smoothing services does Keratin Complex offer?

Keratin Complex offers smoothing solutions for every hair type that cater to the desired result, cost, longevity, waiting period and time in-salon. We recommend that you first undergo a consultation with a Keratin Complex stylist to decide which treatment is best for you. Ask your stylist about our Menu of Services, which offers customizable Keratin Complex treatments to meet your specific needs.

Our signature in-salon smoothing services reduce frizz and curl, improve overall manageability and versatility, and make hair smoother, shinier and healthier-looking.

What happens during a Keratin Complex Smoothing Therapy treatment?

Keratin Complex Smoothing Therapy treatments utilize a simple, four-step process. Your stylist will first use a special deep-clarifying shampoo to prepare the hair for treatment and to remove residue and buildup resulting from previous hair care products. Next, the selected smoothing treatment is applied; the hair is blow-dried and then flat ironed, sealing in the treatment for a smooth, silky finish. Steps may vary depending on the service performed.

Do Keratin Complex keratin treatments straighten the hair?

Keratin Complex Smoothing Therapy treatments are not straightening treatments. Smoothing Therapy treatments reduce curl patterns in curly, wavy or unruly hair, thus providing a straightening effect without permanently changing the structure of the hair. In addition to being easier to maintain after treatment, your hair will have the versatility to be styled curly, wavy or straight as desired.

It is important to discuss your goals with your stylist to understand the overall results you can expect to achieve with a Smoothing Therapy treatment.

How long will my treatment results last?

Treatment longevity may vary depending on the selected treatment, your individual lifestyle, and your at-home maintenance regimen. Natural Keratin Smoothing Treatment and Natural Keratin Smoothing Treatment for Blonde Hair deliver results that last up to five months; Express Blow Out results last up to six weeks; andPersonalized Blow Out™ Same Day Keratin Treatment results last up to three months. Consistent use of Keratin Complex keratin-enhanced products, including our collection of sodium chloride-free and sulfate-free shampoos and conditioners, will help prolong the results of your treatment.

When can I shampoo after a Keratin Complex treatment?

To promote the longest-lasting results, Natural Keratin Smoothing Treatment and Natural Keratin Smoothing Treatment for Blonde Hair require a 72-hour waiting period before shampooing. After an Express Blow Out treatment, we recommend a waiting period of at least eight hours before shampooing.

You may extend the waiting period if desired after Natural Keratin Smoothing Treatment, Natural Keratin Smoothing Treatment for Blonde Hair or Express Blow Out without affecting your results. You may also use Keratin Complex Volumizing Dry Shampoo Lift Powder at any time during the waiting period to absorb excess oil, remove odors, and refresh hair and scalp.

There is no waiting period after Personalized Blow Out™ Same Day Keratin Treatment. You may shampoo, condition and style as desired after treatment.

Your stylist will recommend the best treatment for you based on your lifestyle, hair type and desired results.

What if my hair gets wet during the waiting period?

If your hair gets wet in the waiting period following a Smoothing Therapy treatment, simply blow-dry and flat iron on low heat as soon as possible.

There is no waiting period following the Advanced Glycolic Smoothing System treatment; if your hair does get wet after treatment, it will not impact your results.

How much does a Smoothing Therapy treatment cost?

Prices depend on a variety of factors, including the selected treatment, the density and length of the hair, and choice of salon. Contact your salon for specific pricing.


Can I get a Keratin Complex treatment if I am pregnant or nursing?
