How Long Does Brazilian Blowout Last (And Why)?

Exact Answer: 3 to 4 Months

The Brazilian blowout is a liquid-based hair treatment that involves a keratin formula that bonds to the hair to create a protecting layer around each strand, efficiently depreciating frizz, sealing the cuticle, and defending against any external damage. After administering the treatment, the hair will be blow-dried, arranged and strength, rinsed, and blow-dried again. The heat from the blow dryer activates the chemicals and binds to the hair shaft.

The Brazilian Blowout has a gentle formula customizable to different hair types and is less sensitive post-treatment. After someone gets a keratin treatment, they don’t have many options because they can not tie it in a ponytail or use a hair clip and can not style it. Also, one can not wash it for at least three or four days. Once the treatment is complete, the stylist rinses out the hair, and that is all.

Given that one does not use shampoos that have chlorine and sulfates, the treatment should last for three to four months or even longer if one doesn’t need to wash their hair as frequently as anyone. Once it fades off, the hair will revert to its original wave pattern. Even if someone doesn’t redo it right away, there is no possible line of distinction between the previously treated hair and newly grown ones, unlike other straightening techniques.

The overall process takes like an hour up to an hour and a half. The longest is around two hours and, it all depends on the thickness and quantity of the person’s hair.
The stylist will begin shampooing the hair three to four times to eliminate all the products and build a base for the treatment. It is usually done section by section.

The application of the Brazilian blowout formula always starts from the root of the hair to the tip then blow-dried until smooth. A flat iron heated to 450 degrees will run on the hair to seal the treatment, then shampooed again to rinse it out, accompanied by a deep conditioning mask. Eventually, the hair will again be blow-dried smooth.

Why Does Brazilian Blowout Last That Long?

Brazilian blowout challenges to provide firmer, smoother, and shinier hair. As a result, it is now a go-to hairstyle for people trying to get rid of frizz and achieve fuller and glossier-looking hair. It is always a better approach to be careful when trying out any hair treatment. Some treatments might damage the hair, while others might cost more money with no benefits at all.

The Brazilian blowout treatment usually lasts between three to four months. But, several factors influence the durability of the treatment. Therefore, it is likely to lengthen or shorten the time depending on how well one cares for their hair.
The factors affecting the longevity of the treatment are:

  • Reducing the frequency of rinsing the hair: The more you wash your hair, the more you strip off the keratin treatment. Recommended minimal washing for two or three times a week.
  • Using sulfate-free shampoos/conditioners: Severe chemicals in shampoos and conditioners will reduce the lifespan of the treatment and might also damage the hair. So, it is preferable to use mild, sulfate-free products. Also, one can prolong the treatment by infrequently moistening the hair using water and then applying a conditioner rather than rinsing with shampoo.
  • Must protect the hair while swimming: The saltwater in oceans or chlorinated water in swimming pools is harmful to the Brazilian blowout treatment. Hence, before diving into a pool or in an ocean, it is better to take precautions. One can protect it by applying a smoothing serum. That will help to protect the hair from those harsh chemicals.


Conclusively, The Brazilian Blowout is a specific label of a semi-permanent protein treatment that helps reduce the frizz in and hair and smooths the cuticle for shinier and silkier hair. Unlike Japanese hair straightening, Brazilian Blowouts do not permanently modify the texture of the hair. The words “Brazilian Blowout” and “keratin treatment” are frequently used correspondingly.

However, there is a difference. Often Brazilian Blowout is mistaken as an umbrella word for all other keratin treatments but, it is a specific brand name of liquid keratin treatment. But of course, a perfect Brazilian Blowout can only be done in a salon by a professional stylist who is specifically certified. However, one can recreate this using a DIY keratin treatment, similar to Brazilian Blowout but with proper precautions.
