Keratin Blowout vs. Brazilian Hair Treatment: What You Need to Know About These Treatments

Read this before you head to the salon.

With a country that shifts between humid and dry, there’s no denying a few bad hair days from the good. Frizz and flyaways are very common, so hair straightening treatments like the keratin blowout and Brazilian hair treatment are popular to keep these hair woes under control.

A lot of people confuse the two hair treatments. They are similar in a lot of ways. However, one key detail makes them distinct. Here’s the lowdown on keratin blowout and Brazilian hair treatment to help you decide which one is for you.

What Is a Keratin Blowout?

A keratin blowout is a hair straightening treatment that fills the empty holes in our hair where our natural keratin used to be. It’s like filling the gaps in our hair cuticles to help it become whole again.

Keratin Blowout vs. Brazilian Hair Treatment

Like two sides of the same coin, a keratin blowout and a Brazilian blowout or hair treatment do the same thing—smooth out and straighten your hair. Both treatments create an outer protein layer around the hair, making your locks sleek and shiny. The only difference is that a Brazilian blowout is a trademarked term where a blend of amino acids—smaller molecules—is used. On the other hand, a keratin blowout relies on keratin to fill in the missing gaps in your hair, repair damage, and make your hair look smooth and straight.

How Long Do the Treatments Take?

Keratin blowout can take up to three hours to finish, while a Brazilian hair treatment can be done in as quick as one to two hours in the salon. Both treatments start with some shampooing and blow-drying before the product is applied.

How Is a Keratin Blowout Done?

The keratin formula is applied with a brush and is left on your hair for about thirty minutes. Your stylist then dries and irons your hair to seal in all the nutrients. The duration of the procedure depends on how long or short your hair is. Once done, your hair care professional will advise you not to wash your hair for up to three days to give your hair enough time to absorb all the nutrients from the keratin treatment.

How About a Brazilian Hair Treatment?

After shampooing your hair three or four times to remove dirt and excess, oil, your stylist will apply the formula to your hair one section at a time from the roots to the tips. Then, your hair will be blow-dried and ironed to seal in the treatment. Afterward, your hair will be shampooed and rinsed to remove excess product. Your stylist will then apply a deep-conditioning mask, then blow-dry your hair one last time for a smooth finish.

Unlike a keratin blowout aftercare, you can wash your hair whenever you want after getting a Brazilian hair treatment. You don’t need to wait for three days.

Which Treatment Should I Get?

Keratin blowout works best with extremely frizzy hair. On the other hand, a Brazilian blowout is more customizable for different hair types, making it good for those with fine to medium hair or those with slightly wavy hair.
