Are you considering getting a Brazilian Blowout but worried it might damage your curly hair? Or maybe you’re unsure of the difference between a Brazilian Blowout and a Keratin Treatment. If so, this blog post is for you!

The Brazilian Blowout is a popular hair treatment for people with straight hair, but it’s also an excellent option for curly locks if you want to wear it straight. Not only will it make your hair smoother and easier to manage, but it will also leave your tresses frizz-free for up to 12 weeks.

However, it’s always essential to research any salon treatments you’re considering, so this article will share all the details you need to know about the Brazilian Blowout.

We’ll explain what’s involved in a Brazilian Blowout for curly hair, which types of hair are best suited to this treatment, and what effect it will have on curly, coily, and wavy hair. We’ll also share some simple aftercare tips to keep your hair looking fabulous for longer.

What Is a Brazilian Blowout?

A Brazilian blowout is a semi-permanent keratin treatment that originated in Brazil and is offered by many professional hair salons. A liquid keratin formula is applied to your strands and sealed using hot irons heated to 450°F. This creates a protective layer that straightens the hair strands, seals the cuticle layer, and protects the hair against damage.

This treatment will leave your hair smoother, straighter, and more hydrated, eliminating frizz for up to 12 weeks or even longer. 

Because it’s a semi-permanent treatment, your natural curl pattern won’t be permanently affected. As the keratin layer wears off, your curls or waves will return to their usual shape.

If you’re unsure about the difference between a Brazilian Blowout Treatment and Keratin Treatments, don’t worry. Brazilian Blowout is simply a brand name for a specific type of keratin treatment offered by certain salons. However, unlike some keratin treatments, you can wash and style your hair right after the Brazilian Blowout and there’s no need to avoid exercise for three or four days.

What Does a Brazilian Blowout Do to Curly Hair?

When applied by an expert, a Brazilian Blowout can give excellent results on wavy, curly, and coily hair. 

This keratin treatment straightens hair without completely removing the curls or waves and instantly improves the texture of curly and frizzy hair. It will also leave your hair softer and smoother, helping to repair damaged locks.

The key to achieving a great result is doing your homework and finding a salon that knows how to care for natural hair!

Does a Brazilian Blowout Damage Curly Hair?

The keratin used in a Brazilian blowout will not damage textured hair. In fact, adding keratin will help strengthen your locks, leaving them looking healthier and less likely to develop split ends or break.

However, a Brazilian blowout will make your hair straighter and affect your curl pattern. If you want to wear your hair curly, then it won’t look the same as the curls will be much looser.

In addition, the combination of chemicals involved in this treatment means that it should only be applied by an experienced stylist. It’s essential to check that they have undertaken the necessary training and have been re-certified within the last 12 months – they should be able to show you their latest certificate.

You should always use a salon that is experienced at working with natural curls. Be sure to discuss the treatment with the stylist before they get started so that you know what to expect. And to avoid disappointment, let the stylist know how much of your natural texture you want to keep.

Are Brazilian Blowouts Safe for Colored Hair?

The Brazilian blowout is generally safe for color-treated hair and can help strengthen and repair hair damaged by chemical processing. However, applying this treatment to previously colored hair can reduce the intensity of the color and make it look faded.

If you want to get a fresh color and a Brazilian Blowout on the same day, it’s better to do the color first and then follow up with the blowout. The protective protein layer completely seals the hair shaft, and many people find it helps keep their hair color vibrant for longer. 

If you’d prefer to color your hair after the blowout, leave at least two weeks before applying the color.

How to do a Brazilian Blowout on Curly Hair

First, your hair will be washed with a clarifying shampoo to remove any product buildup that could block the treatment from penetrating the strands. 

Your hair is then towel-dried and soaked in the keratin treatment from root to tip. When your hair is completely saturated, it will be left to process for around 30-45 minutes. 

Next, your stylist will blow dry your hair before passing a flat iron heated to 450°F over your locks. They’ll make multiple passes over each section, and the number of times each section is flat ironed will determine how much your curl pattern is released.

Your blowout will be finished by rinsing out the excess keratin treatment. Then, your stylist will apply a deep conditioner before finally blow drying and styling your hair.

Curly Hair Types Best Suited for Brazilian Blowout

A Brazilian Blowout is suitable for any hair type and can be customized to suit your hair’s individual needs. 

You can try this treatment if you have:

  • Thick hair
  • Curly or wavy hair
  • Straight hair
  • Frizzy hair
  • Unmanageable hair
  • Dry hair

It’s also suitable for damaged hair and hair that lacks shine or is prone to breakage. And because the straightening effect is only temporary, your natural curls or waves will return after 12 weeks or so.

What a Brazilian Blowout Looks Like on Curly Hair

The results of this treatment vary according to your hair type, so here’s what to expect on your curls, coils, or waves.

Type 2 Hair
A Brazilian Blowout is perfect for taming frizz on Type 2 wavy hair. Your waves will be softer and looser than before the treatment, and your hair will be more manageable with better clumping.

Type 3 Hair
The results of a Brazilian Blowout will be more dramatic on Type 3 curls. The treatment will loosen your curls without straightening them entirely. It will also help minimize frizz and reduce some of the volume, and give you better curl definition, especially on second day hair.

Type 4 Hair
A Brazilian Blowout won’t dramatically alter the curl pattern on Type 4 hair. In fact, you might not even notice much difference in the look of your curls, but you’ll undoubtedly be able to tell the difference in the way your hair feels. 

The blowout will leave your hair feeling softer, more hydrated, and less likely to frizz or break. You should also find that your curls are more defined with a little extra length.

Aftercare Tips for Curly Hair With a Brazilian Blowout

These hair treatments are designed to last up to 12 weeks. However, it can last longer on curly hair as curly girls tend to wash their hair less frequently. 

Keeping your blowout looking fabulous is really simple as long as you follow these simple tips:

Use a sulfate-free shampoo and conditioner
Sulfates can cause the keratin protein layer to break down and wash out more quickly. It can also dry out your scalp, which causes more sebum to be released, leading to an oily scalp and greasy-looking hair. 

A sulfate-free shampoo and conditioner will help your treatment last longer and be gentler on your scalp. 

Use products containing keratin
Look out for haircare products that contain keratin, as these will maintain the look of your blowout for longer. 

Don’t wash your hair too frequently
Leaving longer between shampoos will prevent your treatment from wearing off too quickly. You can freshen your hair between wash days with a dry shampoo.

There’s no need to avoid exercise in the days right after your blowout and you can wash your hair as soon as you like. You can also style your hair however you choose.
