Safe Alternatives to Traditional Keratin Treatments

Keratin straightening treatments have become increasingly popular due to their effective frizz fighting abilities and silky, smooth hair. However, many people are still unaware of the potential adverse health effects from exposure to the chemicals used in hair straightening products.

The main issue with the keratin treatments are the formaldehyde vapors that can be released from keratin products during blow drying and flat ironing. Although formaldehyde makes the straightening product more effective and provides longer-lasting results, these advantages are not worth the health risk that you and your stylists are exposed to during the straightening process.

The following smoothing treatments are formulated without formaldehyde or formaldehyde donors and are much safer for clients, stylists, and the environment than standard chemical-based keratin treatments. These innovative smoothing treatments are generally more customizable and give you more styling flexibility than traditional, formaldehyde-containing straightening products.



Cezanne Classic Keratin Smoothing Treatment (formerly known as Cezanne Perfect Finish Keratin Hair Treatment) is advertised to reduce frizz and make hair smoother, stronger, and more beautiful for up to 4 months.

The treatment uses a low pH system to raise hair cuticle and infuse hair fibers with a blend of keratin, sericin, botanical extracts, and vitamins. These healthy ingredients restore lost and damaged keratin and help protect the inner bonds in your hair. Using the heat during flat ironing stage helps lock in the treatment and create a smooth and shiny look.

Cezanne Smoothing Treatment improves the health and strength of the hair, delivers a considerable reduction in frizz, and adds intense shine. The treatment will soften and loosen your curls, but it won’t make your hair bone straight. Your hair will still hold a curl if you desire.

This treatment is especially suitable for people with dry, frizzy, curly, coarse and unmanageable hair who want to cut drying and styling time.

The procedure takes up to two and a half hours, depending on the hair texture and length. The process can be customized to create the desired results.

Unlike chemical-based keratin treatments, you can shampoo your hair the same day and style it the way you want. You can also exercise or go swimming right from the salon. Color service can be performed on the same day, either before or after the smoothing treatment.

To maintain the results, use sulfate-free and salt-free products, and avoid washing your hair daily.

The Treatment can be reapplied after about 4 months. Make sure to consult your stylist, because applying the treatment too often can make your hair feel heavy.

Cezanne Express treatment is available for clients who want a more affordable option or want to cut the time they are spending in the salon. It is less effective than the classic option and is supposed to last about 8 weeks.


Argan Protein Therapy by UNEX PROFESSIONAL promises to make hair straight up to 95 % without the use of Formaldehyde or any other chemicals. You don’t have to inhale toxic fumes that can cause itchy and burning eyes or make your throat hurt.

The treatment is formulated with hydrolyzed keratin, collagen, cysteine protein, and argan oil that are biocompatible to human hair.

The best candidates for receiving Argan Therapy are individuals with damaged, chemically treated, bleached, and frizzy hair.


  • Straightens your hair up to 95 % with no harm to the hair

Argan Protein Therapy can be done at home. However, you may need an extra pair of hands during flat ironing stage to ensure the best results.

The effects last 2-6 months. The product is reapplied approximately every three months.

The procedure will take 2-4 hours, depending on hair length and thickness. To read the directions, visit the manufacturer’s website.


Unique Amino Style Keratin Treatment is a new formaldehyde-free keratin treatment product designed to reduce volume, eliminate frizz, and restore damaged hair. The formula utilizes a blend of amino acids, plus sugar cane and assai extract.

After receiving Unique Amino treatment hair is straighter and looks shiny and healthier.  The styling time is greatly reduced. The results look like those after having a hair Botox treatment.

This treatment will not make your hair pin straight, but it greatly improves the look of dry, damaged, frizzy, or dull hair. When you want to make your hair straight, this can be easily achieved with a few strokes of a flat iron.

The treatment is compatible with other chemical treatments and can be applied to previously straightened, relaxing, or colored hair. However, this treatment can change your hair color to a lighter shade or even leave some brassy tones. To avoid this, it is advisable to dye your hair after, not before the treatment. You can get color service the same day after receiving the Unique Amino Style Treatment.

With proper maintenance, the effects will last between 8 and 12 weeks. The manufacturer offers a complete aftercare line, which includes aftercare shampoo, conditioner, and leave-in conditioner.

The results are progressive and cumulative, so you can apply the treatment every 8 to 10 weeks and your hair will be shinier, and healthier looking with each application.

The manufacturer claims that the product is completely free of harmful chemicals so it is safe to be applied on any type of hair and can be used for children over age 12, as well as for pregnant women.

To obtain the best results, the treatment must be applied by a certified hair professional. The procedure is the same as the application of any other keratin treatment. The product should be left in the hair for about 20 minutes. When the hair is dried up to 70% the stylist uses a flat iron to seal the treatment in with high heat. You can wash your hair the same day and style it the way you want.


Keratin Complex Hair Treatment by Damilla utilizes a blend of natural keratin, silk amino acids, collagen, and soy and wheat proteins to replenish the lost proteins and strengthen hair. Argan oil conditions and softens your tresses, while increasing shine.

Saffron is a spice, derived from the flower of Crocus sativus plants. It is rich in concentrated Vitamin B2, Vitamin B6, and niacin. The company claims that the product, when applied by a professional has immediate results which last 3-4 months.

This straightening treatment has several convenient features that can make the application procedure safer and more comfortable:

  1. Saffron Smoothing Treatment straightens the hair without the use of damaging chemicals and is claimed to be safe for the user and for the stylists.  This product can be used on hair roots, which makes application procedure as well as straightening touchups easier. There are no strong vapors released during the treatment that can cause irritation in your eyes, nose or throat.
  2. This product is easier to apply and the application process takes less time than traditional straightening services. You don’t have to wash your hair before application, which eliminates the initial steps of clarifying as well as blow drying your hair. This means that you will spend less time in the salon and probably pay less money for the straightening service.
  3. Another convenience is that the treatment provides you with an immediate result. There is also no downtime after the treatment. You can color or style your hair the way you want immediately after the procedure or on any of the following days.

Unlike traditional straightening treatments, there is no hair clarifying step prior to the treatment. The product is poured into a bowl and applied to the hair section by section using a hair dye brush. A plastic wrap is then placed tightly over hair for 50 minutes. After removing the plastic wrap, your hair is blow dried for 10 minutes with a flat brush. In the next step, the hair is flat ironed at a temperature of 380-450 Fahrenheit. The final steps also differ from standard straightening treatments. After flat ironing step, the hair is simply washed with sulfate free shampoo, blow dried and styled the way you want.

The treatment is not meant to straighten your hair, so there is no flat-ironing stage. This repairing treatment is designed to reconstruct hair damaged by chemicals and restore hair softness and sheen.

  1. I have used the saffron smoother – got it on Amazon. Highly recommended and you gave a good summary of it.

  2. I’ve had problems with my naturally white hair turning very yellow mustard color. Of course very concerned about this result.

  3. Purple shampoo is the easiest way to get rid of unwanted yellow tones. There are purple masks that serve to the same purpose, but in addition to toning they hydrate and nourish your hair. Purple toners also work on naturally white hair. Discuss all options with your stylist.
