Top 3 Keratin Treatments Without Formaldehyde

Before I show you my top three formaldehyde-free treatments, let’s talk about the typical keratin (Brazillian blowout) process.

Keratin is an essential protein for healthy hair (read more about why keratin is vital). Adding keratin to the hair strands can make them shiny, smooth, and frizz-free. It can also repair damaged hair.

Still, keratin is not enough to straighten curly hair. The formaldehyde in the keratin-rich solution is responsible for changes in hair texture by disrupting the hair bonds.

As FDA explains, “When the solution is heated, the formaldehyde in the product is released into the air as a gas.” Regular exposure to high formaldehyde levels can cause various health issues. (2)

So, which keratin treatment has no formaldehyde? Let’s see my top three picks.

#1 Winner: Cezanne Perfect Finish

Cezanne Perfect Finish Keratin Smoothing Treatment 32 Oz (946 ml)

Let me share my personal journey with the hair game-changer – Cezanne Perfect Finish Keratin Treatment.

This product is a standout among the ones I’ve tried, as it’s free of harsh chemicals and dramatically reduces frizz, giving me manageable and stunningly shiny hair!

Features & Attributes

The Cezanne hair smoothing potion is packed with beneficial ingredients like sericin, aloe vera, keratin, vitamins, and glycolic acid.

It’s a one-size-fits-all solution, suitable for all hair types and textures.


Now, let’s talk size – a generous 32 oz. bottle is what you get. It’s a significant amount, considering the incredible benefits it provides.

Benefits & Drawbacks of Cezanne Perfect Finish

On the flip side of the coin, this product has some drawbacks. It’s on the pricier side compared to other hair straightening treatments I’ve tried.

However, considering the results, it’s an investment worth making! Moreover, it’s best applied by professional hairstylists, which could be a bummer if you’re a DIY enthusiast.

Benefits Drawbacks
It doesn’t contain any hazardous chemicals that can damage the hair or leave unpleasant smells after the treatment.Expensive
Restores the hair cuticle, tames frizzy hair, and gives you shiny hair for monthsProfessional hairstylists should apply it
Suitable for most hair types
You don’t have to wait several days to wash or style your hair after the treatment.
It lasts up to five months

How It Compares to Others

When compared to other products, Keratin Salon Direct shines in its own unique ways.

It’s an excellent keratin alternative that effectively tames frizz, promotes hair growth, and manages unruly hair.

However, if you’re on the hunt for a poker-straight hair effect, this might not be your first pick.

Now, let’s bring Cezanne Perfect Finish into the mix. This product is indeed a premium choice.

It delivers not only smoother, frizz-free hair but also provides a noticeable straightening effect.

What sets it apart is its longevity – one treatment can last up to five months. However, it’s pricier and needs a professional application for the best results.

In conclusion, if you’re looking for an affordable, at-home keratin treatment, Keratin Salon Direct is a solid choice.

But if you’re willing to invest in a more lasting, salon-like result, Cezanne Perfect Finish might be the one for you.

Both are excellent, formaldehyde-free options, and the choice comes down to your personal hair goals and budget.

How It Has Evolved

Here’s another fun fact – compared to other Cezanne hair products I’ve tried, Perfect Finish lasts the longest, keeping your hair smooth and shiny for up to five months.

Expert Tips

A couple of pro tips if you’re using this product: Stick to sulfate-free shampoos and stay away from chlorinated water to maintain your hair’s health post-treatment.

If you’re brave enough to try this at home, make sure to use a quality keratin iron straightener to achieve salon-like results.

Let’s dive into one of my go-to products for healthier hair – Keratin Salon Direct. This fantastic find strikes the right balance between cost and quality.

Benefits & Drawbacks of Keratin Salon Direct

Now, let’s talk pros and cons. What I love about Keratin Salon Direct is its user-friendly application process.

It’s free of toxic chemicals, so you don’t have to worry about harmful reactions or health risks.

Plus, it’s a reliable ally for combatting frizz, promoting hair growth, and taming unruly hair. Unlike many other products, there are no post-treatment restrictions.

On the flip side, though, you might find its peculiar smell a little off-putting. And while it has a reasonably long lifespan, remember that one bottle equals one treatment.

How It Compares to Others

In the sea of hair care products, Keratin Salon Direct, Cezanne Perfect Finish, and Brazilian Keratin Hair Treatment Complex stand out, each with their distinct qualities.

Keratin Salon Direct is your go-to for a cost-effective, frizz-fighting solution.

It’s easy to use at home and packs a punch with botanicals and vitamins, though it may lack the straightening power some users seek.

The Brazilian Keratin Hair Treatment Complex, another noteworthy contender, is known for its effective straightening abilities and deep conditioning.

However, some users might find the application process a bit cumbersome and the post-treatment restrictions inconvenient.

Now, let’s talk about Cezanne Perfect Finish.

This product is a premium choice that delivers salon-like results, reducing frizz while also providing a straightening effect.

It’s gentle on your hair with its formaldehyde-free formulation, and one treatment can last up to five months.

The need for professional application and a higher price tag are part of the deal, but given its benefits, it’s worth every penny.

While each product offers its own set of benefits, Cezanne Perfect Finish steals the show with its overall performance and lasting results.

It’s the best among these options if you’re aiming for a long-lasting, salon-quality finish with noticeable straightening effects and a frizz-free mane.

3 Things to Consider Before Getting Keratin Treatments

After learning that keratin treatment has no formaldehyde, let’s talk about what you should consider before you get a keratin treatment.

#1 Type of Keratin Treatment

Before you get a keratin treatment, you should consider what type you want:

  • Brazilian keratin treatment is the best for curly hair, while Soft keratin is suitable for fine to medium hair. Now, when exploring options, it’s essential to consider the nuances of collagen vs keratin hair treatment.
  • Japzilian keratin combines Brazilian and Japanese hair straightening processes. It’s best if you want something more permanent to alter your hair’s natural texture.
  • Keratin Express uses the same method as Brazilian blowouts, but it lasts up to two months, and it’s best for wavy or straight hair prone to frizziness.

#2 Where To Get the Treatment

Some keratin treatments you can do at home. However, they won’t be as long-lasting as professional ones, especially if you don’t have experience with such hair products.

If you’re curious about how keratins are formed, exploring professional treatments might offer a deeper understanding of the process and potentially lead to more effective and enduring results.

Moreover, if you do a keratin treatment with formaldehyde content, you should do it in a well-ventilated area to reduce the risk of inhaling formaldehyde gas.

#3 Price

According to the professional stylist Paul Labrecque:

“When you pay more, you’re usually paying for a very skilled technician who can feel your hair and know what’s on it and what formula should be picked for your needs and hair type. (3)

So, paying for an expensive keratin treatment can be cheaper in the long run because it’ll last for months and reduce the risk of dry or brittle hair.


Do All Keratin Treatments Contain Formaldehyde?

No, not all keratin treatments contain formaldehyde. Some, like Cezanne, use other safer ingredients to achieve straight hair.

Which Keratin Treatment Is the Safest?

There you have it, the lowdown on keratin treatments without formaldehyde! We’ve explored the highs and lows, and it’s clear that fabulous hair doesn’t have to come at the cost of harsh chemicals.

From budget-friendly Brazilian Keratin Hair Treatment Complex to the high-end Cezanne Perfect Finish, there’s an option for every hair type and budget.

Each has its unique perks, be it long-lasting effects or the ability to tame unruly hair.

Remember, your hair deserves the best. So why not invest in a treatment that not only delivers results but also respects your health?

So, are you ready to embrace smoother, shinier, and healthier hair with a formaldehyde-free keratin treatment? Your dream hair could be just one treatment away!
