Is Brazilian keratin treatment good for hair?



Brazilian keratin treatment has gained immense popularity in recent years as a promising hair care solution. This revolutionary treatment claims to transform dull and frizzy hair into smooth, shiny locks. But is Brazilian keratin treatment really as good for hair as it is believed to be? In this comprehensive article, we will delve into the science, benefits, drawbacks, and everything else you need to know about Brazilian keratin treatment.

Understanding Brazilian Keratin Treatment

Brazilian keratin treatment, also known as a BKT or Brazilian blowout, is a semi-permanent hair smoothing treatment. It involves the application of a solution containing keratin, a protein that is naturally found in our hair. The treatment is designed to replenish and restore the keratin levels, improving the hair's overall condition and texture.

The procedure typically begins by washing the hair with a clarifying shampoo to remove any product buildup or impurities. The hair is then partially or completely dried, depending on the type of treatment. The keratin solution is applied to the hair, section by section, and left to penetrate the hair shaft. After the solution is applied, the hair is dried again and flat ironed to lock in the keratin. Finally, the hair is rinsed, and a keratin-based conditioner is applied.

The Benefits of Brazilian Keratin Treatment

Brazilian keratin treatment offers a plethora of benefits that have made it increasingly popular among people seeking to tame their unruly hair. Let's explore some of the remarkable advantages this treatment provides:

1. Frizz Reduction:

One of the primary goals of Brazilian keratin treatment is to eliminate frizz and make the hair more manageable. By infusing keratin into the hair, the treatment creates a protective barrier, preventing moisture from entering the hair strands and causing frizz.

The keratin acts as a shield against humidity, ensuring that your hair remains sleek and polished even in adverse weather conditions. This benefit is particularly advantageous for individuals with naturally frizzy or coarse hair who struggle to maintain smoothness.

2. Smoothing and Straightening:

Brazilian keratin treatment can significantly improve the texture of your hair, transforming it from rough and unruly to smooth and lustrous. The treatment relaxes the hair by breaking down and reconfiguring the protein bonds within the hair shaft.

As a result, your hair becomes softer, more manageable, and easier to style. For individuals with curly or wavy hair, Brazilian keratin treatment can provide temporary straightening effects, reducing the need for daily heat styling and saving precious time in their hair care routines.

3. Shine Enhancement:

Dull and lackluster hair can make anyone feel less confident. Brazilian keratin treatment addresses this issue by promoting intense shine and vibrancy. The keratin penetrates the hair cuticles, smoothing them out and reflecting light more effectively. This results in sleek, glossy locks that exude health and radiance.

4. Reduced Styling Time:

Are you tired of spending hours trying to tame your mane every morning? Brazilian keratin treatment can significantly cut down your styling time. By eliminating frizz and improving manageability, the treatment allows your hair to fall effortlessly into place.

You can bid farewell to lengthy blow-drying sessions and excessive heat styling. Embracing your natural hair texture becomes effortless, and you'll find that it requires minimal effort to achieve a polished look.

5. Long-Lasting Results:

Unlike many other hair treatments in the market, Brazilian keratin treatment offers semi-permanent results that can last for several months. The effects gradually diminish as the treatment wears off, leaving no visible roots or abrupt changes in hair texture.

With proper care and the use of sulfate-free products, the results of Brazilian keratin treatment can last up to four months. This longevity makes it an attractive option for those seeking a low-maintenance hair care routine.

The Drawbacks and Considerations

While Brazilian keratin treatment indeed offers a multitude of benefits, it is essential to consider the potential drawbacks and precautions associated with the procedure. Let's explore some of the factors you should be aware of before opting for the treatment:

1. Chemical Composition:

Brazilian keratin treatment typically contains ingredients such as formaldehyde or other chemical compounds that release formaldehyde gas when subjected to high heat. Although various formulations claim to be formaldehyde-free, it's crucial to choose a reputable brand or consult a professional to ensure your safety.

Formaldehyde is a known human carcinogen and can cause allergic reactions, skin irritations, respiratory issues, and other health concerns. It is important to note that the safety of Brazilian keratin treatment largely depends on the product used and the expertise of the stylist performing the treatment.

2. Salon Quality and Expertise:

To achieve optimal results and minimize the risk of complications, it is vital to undergo Brazilian keratin treatment at a reputable salon with experienced professionals. While at-home treatment kits may exist, they may not deliver the same level of expertise and quality results as a professional salon treatment.

3. Maintenance and Aftercare:

Brazilian keratin treatment requires specific care and aftercare procedures to prolong its effectiveness. For example, you must avoid washing your hair or exposing it to moisture for a designated period (usually 72 hours) after the treatment.

Additionally, to maintain the longevity of the treatment, it is crucial to use sulfate-free shampoo and conditioner, avoid excessive heat styling, and limit exposure to chlorine and saltwater.


In conclusion, Brazilian keratin treatment can be a valuable hair care option for individuals seeking to tackle frizz, achieve smoother strands, and enhance shine. Its ability to transform unruly locks into manageable, shiny hair has made it a popular choice among many.

However, it is crucial to exercise caution and consider the potential risks associated with certain formulations and salon practices. Safety should always be a priority. Consulting with a trusted stylist and choosing reputable products can help mitigate the concerns while maximizing the benefits of Brazilian keratin treatment.

Remember, everyone's hair is unique, and what works for one person may not work for another. Therefore, it is advisable to weigh the pros and cons, consult with professionals, and make an informed decision based on your hair type, preferences, and desired outcomes. With proper care and consideration, Brazilian keratin treatment can indeed be a game-changer for those looking to achieve smoother, healthier hair.
