My Brazilian Blowout Review (with Before and Afters)

I trust my stylist like a sister, so when she said I was the perfect candidate for a Brazilian Blowout, I was on board. If you’ve ever browsed Pinterest for hair inspiration, you’ve probably stumbled on before and after photos of a Brazilian Blowout.

It’s one of the most popular hair smoothing treatments around the world, eliminating frizz and sealing the cuticle to prevent damage. It also adds moisture and shine. I’ve been getting Brazilian Blowouts 1-2 times per year since 2017. In this review, I share everything you need to know about the Brazilian Blowout before you commit.

So, curious to know what the Brazilian Blowout does, its cost, and whether it’s right for your hair type? Keep on reading for my review of the Brazilian Blowout treatment or click to jump to the summary.

What is a Brazilian Blowout?

The Brazilian Blowout hair treatment is a smoothing treatment that originated in Brazil. It’s designed to eliminate frizz, hydrate, seal the hair shaft to prevent damage from heat styling. It also adds overall shine and gloss. The amino acid formula used in the treatment incorporates Brazilian ingredients like camu camu, acai berry, and annato seed. Its bonding technologies create a protective layer around each strand of hair. This smooths and straightens the hair while allowing you to heat style it (curl, flat iron, wave, blow dry).

What is the average cost of a Brazilian Blowout hair treatment?

The cost of the treatment depends on two factors: the salon and the length/thickness of your hair. Since I have a lot of hair and it’s long, my treatments cost roughly $400. The average cost of a Brazilian Blowout treatment ranges from $200 to $500.

What is the difference between a Brazilian Blowout and a Keratin Treatment?

Both are smoothing treatments that add radiant shine and eliminate frizz, but Brazilian Blowouts are more customizable.

A Keratin straightening treatment gives you a stick-straight texture, you can’t shower for 3-4 days after your hairdresser applies it, and you can’t really heat style it to alter the look (curl it, wave it, braid, etc.).

The Brazilian gives you your hair but relaxed, smoother, and shinier. Unlike a traditional keratin treatment, a Brazilian doesn’t make your hair completely straight. My hair is smooth as butter with a slight wave, and I can still use a curling iron, flat iron, etc.

How long does a Brazilian Blowout treatment last?

My Brazilian Blowout lasts anywhere from 4-6 months, depending on how often I’m washing and styling my hair. As the treatment wears off, I’ll notice texture around my hairline first. But there isn’t an obvious demarcation line. 

One cool thing about the Brazilian Blowout is that the treatments build on one another. Now that I get them regularly, my stylist doesn’t need to use as much formula. This = $$ savings, and the results seem to last longer.

How long does the Brazilian Blowout process take?

The entire Brazilian Blowout process takes 1-2 hours. It’s dependent on how much hair you have, the condition of your hair, and how curly it is.

Here’s the step-by-step process:

  1. Your stylist cleans your hair with a clarifying shampoo 2-3 times that will make it feel like straw. This removes all product so that the formula can attach.
  2. Working in sections, the Brazilian Blowout treatment is applied with a brush from root to tip.
  3. The hair is blow-dried smooth and straight with the treatment in it.
  4. The treatment is sealed into your hair with a very hot flat iron.
  5. Your hairdresser may wash your hair again and apply a deep conditioning treatment.

During the process, the formula can be uncomfortable if you have sensitive eyes. I hold a towel over my face while my stylist is using one of her straighteners to go around my face-framing pieces. Also, your stylist should be able to detect this based on the condition of the hair, but if your hair can’t take a lot of heat, as breakage can occur if your stylist goes too hard with the flat iron.

Brazilian Blowout Hair Treatment Pros and Cons


  • Amazing option for women with frizzy hair or curly hair in humid environments who want frizz-free hair for an extended period of time.
  • Makes your hair look smooth and glossy, and it improves the condition of your hair by protecting it when you’re blow-drying and heat styling.
  • The smoothness, shine, and anti-frizz come without a loss of volume or a greasy feeling.
  • Significantly reduces air-drying and blow-drying time.
  • The gentle formula (compared to a Keratin treatment) is flexible, allowing you to achieve any hairstyle (classic curls, loose waves, braids, straight, etc.) you want.
  • It’s safe for color-treated hair.


  • The treatment is expensive, costing $300+ for most hair types.
  • If you shower daily, the treatment may only last 10-12 weeks.
  • The aftercare instructions recommend that you avoid salt water, chlorine, and use a sulfate-free, color-safe shampoo and conditioner.
  • It is not safe for pregnant women.
  • Like many hair straightening formulas, the Brazilian formula contains formaldehyde. There’s controversy surrounding this ingredient. Be sure to wear a mask and make sure the salon is well-ventilated. Some salons carry formaldehyde-free formulas.

Who’s the Treatment Best For?

This treatment is best for:

  • Women who are exhausted with their frizzy, wavy, or curly hair and want their styling process (or air drying process!) to be quick and easy.
  • Those who want smooth, shiny, frizz-free hair that is more relaxed than your normal texture but not pin straight or stick straight hair.
  • People looking for a relaxing treatment that will still allow you to style your hair with hot tools (curl it, wave it, dry it, hot roll it, etc.).
  • Women who live in a humid area and have frustrating frizz or volume.

My Honest Review of the Brazilian Blowout Treatment

It’s important for you to know that my natural hair is fine, wavy, and has some frizz—and I have a lot of it. In my pre-Brazilian days, it took me nearly 45 minutes just to blow dry my hair. There was also always some frustration about having small waves or kinks at around my hairline, neck, and at the back of my head when I straightened, curled, or blew-dry my hair.

The price tag turned me off when my stylist recommended it. But I trusted her, gave it a go, and it’s been such a game-changer for me.

Here’s my review: The Brazilian Blowout treatment allows me to both air dry beautifully and achieve the loose curls, classic waves, and fun hairstyles I love with smoothness, shine, and ease that I’ve never experienced before. I was always jealous of women who could simply get out of the shower and go about their day with air-dried hair—my hair used to take 4+ hours to air-dry. With the Brazilian keratin hair treatment, my hair air-dries smooth and shiny, but I can also blow-dry and heat style it in under 30 minutes.

While the cost isn’t ideal, the changes it makes to my hair and lifestyle are incredible. When I’m diligent about washing infrequently, my Brazilian can last 6-12 months. If you break down how much it costs me ($400), that’s less than $50/month.
