What Is a Brazilian Blowout? Everything You Need To Know
A Brazilian blowout is a keratin-based smoothing treatment that reduces frizz and cuts down blow-dry time, without fully straightening curl pattern the way a keratin treatment or relaxer does. Today’s technology has made smooth, frizz-free hair achievable without hours of flat-ironing every day — here’s everything you need to know about how Brazilian blowouts work, how long they last, and how to care for one.
What Is a Brazilian Blowout?
A Brazilian blowout is a type of hair-smoothing treatment that uses keratin to smooth hair and reduce frizz. The treatment originated in Brazil (hence the name) and has become increasingly popular in the United States. It’s similar to a keratin treatment, but a few key differences exist: a Brazilian blowout typically preserves more natural movement and can be customized to leave some texture, while a traditional keratin treatment or relaxer straightens hair more dramatically and permanently.
In a Brazilian blowout, a silicone-based, keratin-infused serum is applied to the hair and then sealed in with heat from a flat iron. This creates a protective layer around each strand, which smooths the hair and reduces frizz while making it more manageable.
How Does a Brazilian Blowout Work?
A Brazilian blowout works by infusing your hair with keratin, a protein that naturally exists in your hair. The keratin bonds with your hair, creating a protective layer around each strand. This smooths the hair’s outer layer (the cuticle), which reduces frizz and cuts down on styling time, while helping protect your hair from heat and humidity.
Is a Brazilian Blowout Safe?
Brazilian blowout treatments have been deemed safe by the FDA. Some early formulas raised concerns about formaldehyde exposure during the heat-sealing step, but reputable salons today use low- or formaldehyde-free formulas and proper ventilation. Ask your stylist which formula they use if you have sensitivities.
The Brazilian Blowout Process
The Brazilian blowout process typically takes about 90 minutes, depending on the length and thickness of your hair. During the treatment, your stylist applies the keratin solution to your hair, then uses a flat iron to seal it in.
Afterward, you’ll need to avoid washing your hair for at least three days so the keratin can fully bond and create its protective layer. Once the three days are up, you can wash and style your hair as usual.
One of the best things about a Brazilian blowout is that it’s highly customizable to your hair type. If you have frizzy hair, your stylist can adjust the formula to tame frizz specifically. If you have thin or damaged hair, they can use a lighter formula to minimize additional stress on your strands.
How Long Does a Brazilian Blowout Last?
A Brazilian blowout typically lasts about three months, though this varies based on your hair growth rate, hair type, and how often you wash your hair. Getting a touch-up roughly every 12 weeks is recommended to keep your results looking fresh.

How to Care for Brazilian Blowout-Treated Hair
To get the most out of your Brazilian blowout, follow these aftercare steps (we cover this in more detail in our full Brazilian blowout aftercare guide):
- Avoid washing your hair for the first three days after treatment.
- Use a sulfate-free shampoo and conditioner once you do wash.
- Skip hot tools for at least two weeks following treatment.
- After two weeks, resume hot tools as desired, using a heat protectant spray beforehand.
- Be extra gentle when brushing, since treated hair is more prone to breakage.

Frequently Asked Questions
Is a Brazilian blowout the same as a keratin treatment?
They’re closely related but not identical. Both use keratin to smooth hair, but a Brazilian blowout is generally gentler and preserves more natural texture, while a traditional keratin treatment straightens more aggressively and lasts slightly longer.
How much does a Brazilian blowout cost?
Pricing depends on hair length, thickness, and condition. Book a consultation with our stylists for an accurate quote based on your hair.
Can I wash my hair right after a Brazilian blowout?
No — wait at least three days after treatment before washing, so the keratin fully bonds to your hair.
Will a Brazilian blowout damage my hair?
When performed by a trained stylist with a quality formula, a Brazilian blowout is not damaging for most hair types. Proper aftercare (sulfate-free products, minimal early heat styling) further protects your results.
