Which is better Brazilian or keratin?


Brazilian or Keratin: The Battle of Hair Treatments


Having luscious and manageable hair has always been a dream for many. To achieve this, various hair treatments have been developed over the years. Among these, the Brazilian and keratin treatments have gained immense popularity. Both offer excellent hair-smoothing results, making it challenging for individuals to choose between the two. In this article, we will explore the key differences between Brazilian and keratin treatments to help you make an informed decision about which one is better suited for your hair.

The Brazilian Treatment: Unveiling the Magic

The Brazilian treatment, also known as Brazilian blowout, is a hair straightening procedure that aims to eliminate frizz and create a shiny, smooth, and more manageable hairstyle. The process involves coating the hair with a liquid keratin formula and then sealing it using a hot flat iron. The heat activates the keratin, which penetrates the hair cuticles, leaving your locks glossy and straight.

The Brazilian treatment is particularly popular among individuals with curly, frizzy, or unmanageable hair. It is performed by hair professionals and typically takes around two to three hours, depending on the hair length and thickness. The results can last up to three months, depending on proper aftercare and the individual's hair type.

One of the key advantages of the Brazilian treatment is its ability to preserve the hair's natural texture while reducing frizz. Unlike other chemical treatments that completely alter hair structure, the Brazilian blowout leaves your hair looking more natural. It also provides flexibility, as you can choose to wear your hair straight or opt for a wavy look by simply styling it with hair tools.

However, it is important to note that the Brazilian treatment contains formaldehyde or similar chemicals. These ingredients have raised concerns regarding their potential health risks, such as eye and skin irritation. Therefore, it is crucial to select a salon or stylist well-versed in the safety protocols involved in the Brazilian treatment to minimize any potential risks.

Keratin Treatment: Unveiling the Science

Similar to the Brazilian treatment, keratin treatments are aimed at smoothing out frizzy hair and providing a sleeker look. However, the process and composition of the keratin treatment differ. A keratin treatment infuses the hair with a hydrolyzed keratin solution using heat. The keratin molecules penetrate the hair fibres, reducing frizz, smoothing the cuticles, and resulting in straighter, shinier hair.

The application of a keratin treatment typically takes between one to two hours and is performed by a professional stylist. The treatment's longevity varies, with results lasting for up to four months, depending on the individual's hair type and aftercare routine.

One of the significant advantages of keratin treatments is that they work well on all hair types, including damaged and chemically treated hair. Keratin is a naturally occurring protein found in hair, skin, and nails, making it a safer option. It strengthens the hair shaft, repairs damage, and adds a protective layer that shields the hair from external factors such as humidity, heat, and pollution.

It is important to note that not all keratin treatments are free from formaldehyde. Many popular brands have introduced formaldehyde-free options, addressing the health concerns associated with the treatment. These formaldehyde-free formulas still provide the same smoothing benefits without compromising safety.

Comparing the Brazilian and Keratin Treatments:

Now that we have explored the fundamentals of both treatments, it's time to delve into a detailed comparison to determine which one stands out:

Application Process:

The process of applying a Brazilian treatment involves washing the hair, drying it, applying the keratin formula, and then sealing it with a flat iron. On the other hand, a keratin treatment requires washing, drying, applying the keratin product, and then undergoing a heat treatment. While both processes are somewhat similar, the Brazilian treatment generally takes slightly longer due to the sealing step.


Both the Brazilian and keratin treatments provide excellent results in terms of frizz reduction, hair straightening, and added shine. However, the Brazilian treatment focuses more on reducing frizz while preserving the natural texture of the hair. The keratin treatment, on the other hand, offers more pronounced straightening results, making it a popular choice for individuals seeking a sleek, polished look.


The longevity of the treatments is a significant factor to consider. Brazilian treatments typically last up to three months, while keratin treatments can last up to four months. However, both can vary depending on an individual's hair type, aftercare routine, and the specific products used. Consistently using sulfate-free shampoos and conditioners, limiting exposure to chlorine and saltwater, and avoiding excessive heat styling can help extend the longevity of either treatment.

Care and Maintenance:

To maximize the results of both treatments, certain care and maintenance routines are essential. Both treatments require the use of sulfate-free hair care products to maintain the longevity of the treatment. Additionally, avoiding certain activities such as swimming in chlorinated water or excessive heat styling will help preserve the treatment's effects. Regular touch-ups may also be required to maintain the desired look, depending on how fast your hair grows.

Health and Safety:

Safety is a top concern for individuals considering hair treatments. Both the Brazilian and keratin treatments contain chemicals that have raised health concerns, particularly formaldehyde. However, many reputable brands have introduced formaldehyde-free options for both treatments, eliminating these health risks. It is crucial to choose a professional stylist who uses high-quality products and follows safety protocols to minimize any potential risks.


In conclusion, both Brazilian and keratin treatments have their unique advantages and cater to different hair needs. If you desire a more natural look with reduced frizz, the Brazilian treatment is an excellent choice. On the other hand, if you prefer a sleek, straight result, the keratin treatment may be more suitable. Ultimately, consulting with a hair professional is crucial in determining the best treatment for your hair type and desired results. Remember to prioritize safety and do your research before committing to any hair treatment. With the right knowledge, you'll be well-equipped to make an informed decision and achieve the hair of your dreams.
