Brazilian Blowout Vs Japanese Straightening: A Comparison

Curious about the difference between Japanese hair straightening vs Brazilian blowout?

I hear you; it’s a bit confusing!

Don’t worry; I’ll guide you through the differences between these two popular methods and help you decide which is right.

Let’s jump right in and get started, shall we?

Brazilian Blowout Vs. Japanese Straightening; What’s the Difference?

The Brazilian blowout is a modern technique that leaves your hair soft and shiny with a natural look and feels.

The method uses keratin proteins that reduce frizz while smoothing out the cuticle layer of each strand. [2]

Sealed within the hair shaft, the keratin becomes impenetrable to humidity, which helps prevent future damage.

Depending on how often you wash your hair, you can use this treatment once every 6-8 weeks. That’s right! Your style will last up to 4 months with one treatment!  

Brazilian Blowout is the only thermal reconditioning treatment that uses patented ion technology in its formulas.

This amazing technology makes the cuticle in each hair strand lay flat, eliminating that dreaded frizz while sealing in natural moisture.

A Japanese straightening treatment is similar to a Brazilian blowout in many ways, but the result is different.

The technique was invented in Japan as a solution for those who had naturally curly or damaged hair that was difficult to maintain.

It involves applying chemicals to your hair that temporarily change its internal structure by increasing its strength, then using an iron or flat iron to achieve straightness.

The main difference between these two treatments is in how long they last.

Both require several hours in the salon.

However, the Brazilian blowout is meant to last for six to eight weeks before needing another round of perms or relaxers.

On the other hand, despite people calling it a “permanent” solution, Japanese straightening lasts only one to three months.

Brazilian Blowout Vs Japanese Straightening; What to Choose?

These treatments offer several benefits for curly and frazzled strands.

However, if not properly applied, Japanese straightening treatment may cause some damage to the hair and scalp.

Brazilian blowouts are the most popular choice for frizzy hair because it’s a fairly simple process with minimal risk.

While Japanese straightening, on the other hand, is a more complicated method that may cause damage to the hair if applied poorly.

Many people often wonder, “Is a blow dryer better than a straightener?” The answer depends on your hair type, desired look, and the health of your hair.

Both Brazilian hair straightening and Japanese hair straightening have different pros and cons. So, your stylist, with their expertise, will guide you to the best choice tailored to your needs.

Brazilian Blowout vs Keratin

Brazilian Blowout is a very popular and cost-effective way of getting your hair straighter. It is my pick for the most innovative and modern method of straightening hair.

If you plan to get a Brazilian Blowout done for yourself, you must know what it is and how it works.

The keratin treatment involves using a keratin-based mixture to protect your hair from damage and pollution.

This treatment gives a firm hold on the hair, which lasts for as long as two months when it is carried out.

But the Brazilian Blowout is not as strong as the keratin treatment; it is more of a temporary solution to make your hair soft and shiny.

The Brazilian Blowout only lasts for about three to four months. After that, you need to go for another round of this process.

Both treatments’ procedures are almost similar and are carried out at salons.

However, the Brazilian Blowout lasts longer than keratin because it contains conditioning agents, which help make your hair stronger.

Besides, if you want to color your hair, you can do so with Brazilian Blowout, whereas coloring over keratin.

We’ve reviewed pretty much everything you need to know already, but let’s look at some other questions and quickly summarize the key points, shall we?

Does Japanese Hair Straightening Eliminate Frizz?

This treatment will transform your locks into a sleeker, shinier version and eliminate frizz. It can last up to four months or longer, depending on the condition of your hair and how you take care of it.

Is Brazilian Hair Straightening Better Than The Japanese Method?

Brazilian Blowout is better in most cases. The Japanese method can seriously damage hair because it breaks the bonds that hold the strands together.
This causes the hair to become dry, brittle, and weak. In turn, your hair becomes unhealthy, causing it to break off at the scalp or split into several hair strands.
Many people have switched from Japanese straightening to Brazilian blowout because it is safer for you and makes your hair more beautiful.


Bottom line, in the Japanese hair straightening vs Brazilian Blowout debate, the Brazilian method usually wins because it’s typically gentler to your locks.

However, it depends on your hair, how long you want the results to last, and other factors you may not even consider.

That’s why it’s important to talk to your stylist and ask them what they recommend.
