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

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.
  • 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.

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.
