Whether you’re looking to tame your locks or looking for a way to ease your hair routine, deciding between a brazilian blowout or a keratin treatment can be tricky. 

Especially since both treatments essentially have the same effect on hair; they both eliminate frizz and boost shine. They’re safe for all hair types and can be done on colour-treated hair. 

Both treatments, however, may contain formaldehyde and other chemicals, so it is important to discuss your options with your stylist, in order to make sure you pick the right one for you.

Read on to find out more about the differences between the two treatments and what to take into consideration before deciding which treatment is best for you.

Best Candidates

A keratin treatment will calm unruly hair, creating a much straighter and sleeker appearance. This is the best option for hair that is overly curly and voluminous. The treatment will reduce the volume and make the hair far easier to manage. 

A keratin treatment is not recommended for use on hair that is already straight or particularly fine as it tends to further reduce volume.

If your aim is to keep volume and movement whilst making the hair frizz-free and more manageable, then a Brazilian Blowout may be a more suitable choice. This treatment performs well with fine to medium texture, and some slight waves or curls. 


One of the notable differences between Brazilian Blowout and Keratin treatment is the time they take to complete.

The Brazilian Blowout process only takes 1 to 2 hours in a salon. 

A Keratin treatment may take up to three hours to perform.

Both treatments start with preparing the hair by shampooing with a clarifying shampoo followed by a towel dry.


After a keratin treatment the hair will have a much straighter appearance and will have less volume. Your hair will be frizz-free for up to 3 months.

After a Brazilian Blowout treatment your hair will be frizz-free, but as this is a “lighter” treatment compared to the keratin treatment it will be less straight. The wavy hair will be straighter with much more of a natural wave and body to it. The curly hair will retain its natural curls, but the curls are softer, frizz-free, and easier to control. Styling the hair with straightening irons or blow drying it straight is far easier and produces better results than before.

Both treatments are customizable depending on the desired results, although the Brazilian Blowout is more flexible. By adjusting the amount of product applied to the hair as well as the level of heat, the results can be tailored to suit the individual’s requirements.


The Brazilian Blowout is a more convenient option because the results are almost instant.

After a keratin treatment, there are certain precautions that must be adhered to, including the 72-hour waiting period to ensure the treatment works successfully. You are requested to leave the salon by keeping the product in your hair and to rinse it after three days. You also should avoid sweating, tying hair back, tucking the hair behind ears, or any style that may cause a kink in the hair.

A Brazilian Blowout treatment is complete when you leave the salon and your results are visible right after the service. Your hair can be washed that same day, and you can also freely style your hair.
