Safe Alternatives to Traditional Keratin Treatments

Last Updated on January 3, 2023 by Gaga

Keratin straightening treatments have become increasingly popular due to their frizz-fighting abilities and silky, smooth finish. However, many people are still unaware of the possible adverse health effects of exposure to the chemicals that can be found in hair straightening products.

The main issue with the keratin treatments is the formaldehyde vapors that can be released during blow-drying and flat ironing. Although formaldehyde makes the straightening solution more effective, this advantage is 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 formaldehyde-based keratin treatments. These innovative smoothing treatments can be customized to your liking and give you more styling flexibility than traditional straightening treatments.

1. Keratin Cure Gold & Honey Bio Hair Treatment

Keratin Cure Gold & Honey Bio Hair Treatment is a glycolic-based smoothing treatment. It is designed to infuse your hair with powerful moisturizing and shine-enhancing ingredients. It smoothens rough and unruly hair, adds shine, and keeps your locks frizz-free for up to 3 months. It is not supposed to make your hair pin-straight, but it does make it frizz-free, soft, and silky. If your hair is curly, you will get glamorous loose waves. This hair smoothing treatment does not contain harmful chemicals.

How it works:

Keratin amino acids act as crosslinking agents that link the hair’s protein and the added keratin, strengthening hair fibers from the root to the tip.

Silk Protein fills in the gaps in the hair cuticle, reducing porosity and giving a silky feel to the hair.

Behentrimonium Methosulfate is known for its de-tangling, hair thickening, and cuticle smoothing properties.

Hyaluronic Acid nourishes the scalp and moisturizes your hair, improving its softness and shine.

The nourishing blend of organic oils includes coconut, argan, hemp seed, marula, and peppermint oils.

Hair types:

Keratin Cure Gold & Honey Bio Hair Treatment works well on frizzy, unruly dry, damaged, or overprocessed hair.


  • Smoothens your hair and makes it easier to manage
  • Eliminates frizz and leaves hair silky soft
  • Leaves hair hydrated and shiny
  • Rebuilds inner strength and boosts volume
  • Reduces breakage and encourages hair growth
  • Soften your hair’s natural waves
  • Reduces blow-dry time
  • Hair can be washed on the same day of the treatment


  • The product has a strong odor that lingers in your hair.
  • Straightening can make the color lighter, especially if your hair is bleached.

The application and aftercare

The application process takes 2 – 3 hours depending on your hair length and type. You will need a clarifying shampoo, wide-toothed comb, blow dryer, and flat iron that can reach and maintain a temperature of about 450F. For maximum absorption, your hair needs to be clean prior to application. The product comes with detailed instructions on how to use it.

To get optimum results, a licensed hair professional should perform the treatment.

You can wash your hair the same day after receiving the treatment. You can also style your hair the way you want. You are supposed to use sulfate- and salt-free products when washing your hair.

2. Unique Amino Style Keratin Treatment 

This innovative formaldehyde-free keratin treatment product is designed to reduce volume, eliminate frizz, and restore damaged hair. The formula uses a blend of amino acids, sugar cane, and acai extract.

Hair types:

The treatment is compatible with other chemical hair treatments and can be applied to previously straightened, relaxed, 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. For your convenience, you can get color service the same day after receiving the Unique Amino Style Treatment.

According to the manufacturer’s claim, this product is completely free of harmful chemicals and safe to use on any type of hair.


  • After receiving the Unique Amino treatment hair looks straighter, shinier, and healthier. The styling time is greatly reduced. The results resemble those obtained after applying 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. If you want to make your hair completely straight, you can do it with a few strokes of a flat iron.

The procedure and aftercare

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

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 that you can apply the treatment every 8 to 10 weeks and your hair will look shinier and healthier with each application.

3. Cezanne Perfect Finish Keratin Smoothing Treatment

This hair smoothing treatment (formerly known as Cezanne Perfect Finish Keratin Hair Treatment) is advertised to reduce frizz and make hair smoother, stronger, and shinier for up to 4 months.

Hair types:

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

How it works:

The treatment uses a low pH system to raise hair cuticles and infuse hair strands with a blend of keratin, sericin, botanical extracts, and vitamins. These healthy ingredients replenish lost and damaged keratin and help protect the inner hair bonds. The heat in the flat ironing stage helps lock in the treatment and create a smooth and shiny finish.


  • Cezanne Smoothing Treatment improves the strength of the hair, reduces 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 that.

The procedure and aftercare

The procedure takes up to two and a half hours, depending on the hair texture and length. The stylist can customize the process to obtain the desired results.

Cezanne Express treatment formula is meant for clients who want a more affordable treatment option or want to cut the time spent in the salon. It is less effective than the classic option and lasts about 8 weeks.

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 the same day, either before or after the smoothing treatment.

To maintain the results, use sulfate-free and salt-free products. Daily washing is not recommended.

The Treatment can be reapplied after about 4 months. Make sure to consult your stylist, because frequent applications can make your hair feel heavy.

5. SAFFRON SECRET Formaldehyde Free Saffron Smoothing Treatment

SAFFRON SECRET Smoothing Treatment uses an organic saffron-based formula to make wavy, frizzy, and curly hair straighter, healthier-looking, and more manageable. Saffron is a spice, derived from the flower of Crocus sativus plants. The spice is rich in concentrated Vitamin B2, Vitamin B6, and niacin. The company claims that the product, when properly applied, gives instant smoothing results that last up to four months.

How it works:

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 stylist. This product can be used on hair roots, which makes the initial application procedure as well as touchups easier. There are no strong vapors that can irritate 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. 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 the hair for 50 minutes. After removing the plastic wrap, your hair is blow-dried and brushed for 10 minutes. Your hair is then flat ironed at a temperature of 380-450 Fahrenheit.

4. The final steps also differ from standard straightening treatments. After the flat ironing step, the hair is simply washed with a sulfate-free shampoo, blow-dried, and styled.

5. Another convenience is that the treatment provides you with an instant result. Plus, there is no downtime. You can color or style your hair the way you want immediately after the procedure is completed or on any of the following days.

6. Keratin Komplex Hair Treatment by Damilla

The product is non-toxic and easy to use at home. One bottle is sufficient for multiple applications.


The treatment gives you straighter, frizz-free, and easy-to-manage hair for up to two months.

7. Paul Mitchell Awapuhi Wild Ginger KeraTriplex Treatment (Available at Walmart)

This frizz-fighting treatment uses isolated proteins identical to human keratin to replace keratin lost during chemical services.

This repairing treatment is designed to reconstruct hair damaged by chemicals and restore hair softness and sheen.

KeraTriplex Treatment is much easier to apply than traditional keratin straightening treatments.

8. Amino Acid-Based Smoothing Treatments

This type of smoothing treatments utilize amino acids to tame your curls, control unwanted volume, and make your hair smooth for up to three months. The formula penetrates deep into the hair shaft to fill up tiny gaps, resulting in smoother, frizz-free, and more manageable hair.

The most popular amino acid-based smoothing treatments include Cysteine smoothing treatment, Pravana Perfection SmoothOut, CHI Enviro American Smoothing Treatment, Argil Therapy, and Thermafuse f450 Amino Fusion Smoothing Treatment.

Popular Brazilian Blowout Smoothing Treatment also uses amino acids to smooth hair. However, this line of products has formaldehyde in its formula.

Amino-acid smoothing treatments can be performed on all hair types including color-treated, highlighted, bleached, permed, relaxed, and keratin-straightened hair.

The application process is similar to keratin treatments. However, your hair can be washed the same day using an appropriate shampoo and conditioner.

7 thoughts on “Safe Alternatives to Traditional Keratin Treatments”

  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.

  4. This is so misleading. According to the government website, “Glycolic acid does exhibit some inhalation toxicity and can cause respiratory, thymus, and liver damage if present in very high levels over long periods of time.”
    Just don’t use it.

  5. I kit had the Cezzane one done at a salon and it’s awful. Left my hair so dried out that I need a good 2 inches cut off., it also didn’t work very well. Skip this one.

    In the past, I’ve had the majestic hair Botox done. Which is also formaldehyde-free. And it worked very well, though like the others it leaves your hair very brassy.
