How long does Brazilian keratin treatment last?


Are you tired of dealing with frizzy and unmanageable hair? Do you dream of having silky and smooth locks that are easy to style? If so, then Brazilian keratin treatment might be the answer you've been looking for. This revolutionary hair treatment has gained popularity in recent years thanks to its ability to transform even the most unruly hair into a sleek and straight mane. But how long does this transformation last? In this article, we will delve into the details of Brazilian keratin treatment and explore the factors that affect its longevity.

The Basics of Brazilian Keratin Treatment

Before we dive into the duration of Brazilian keratin treatment, it's important to understand what this treatment entails. Brazilian keratin treatment, also known as Brazilian blowout or keratin straightening, is a hair smoothening procedure that aims to reduce frizz, tame curls, and make hair more manageable. This treatment involves the use of a keratin-based formula that is applied to the hair and sealed in with heat. The keratin penetrates the hair shaft, creating a protective layer that smoothens the cuticles and eliminates frizz.

One of the main reasons why Brazilian keratin treatment has gained so much popularity is its ability to transform even the most stubborn hair types. Whether you have curly, wavy, or frizzy hair, this treatment can help you achieve straight, shiny, and more manageable hair. However, the duration of the treatment's effects can vary depending on several factors.

The Impact of Hair Type

When it comes to the longevity of Brazilian keratin treatment, your hair type plays a significant role. Naturally, individuals with coarser and more resistant hair tend to see longer-lasting results compared to those with finer hair. The structure and texture of your hair determine how well it retains the keratin treatment. Coarse hair usually has a stronger cuticle layer, allowing it to hold on to the keratin and maintain the smoothness for a longer period.

On the other hand, individuals with fine or thin hair may experience a shorter lifespan of the treatment. Fine hair tends to have a more delicate cuticle layer, making it easier for the treatment to wear off. However, it's important to note that even if the effects fade quicker on fine hair, it can still benefit from the treatment by reducing frizz and making the hair more manageable.

Aftercare and Maintenance

Another crucial factor that affects the duration of Brazilian keratin treatment is the aftercare and maintenance routine. To ensure that the treatment lasts for as long as possible, it's important to follow the guidelines provided by your stylist. After the treatment, you may be advised to avoid washing your hair for a certain period to allow the keratin to fully settle into the hair shaft.

Additionally, it's important to use sulfate-free shampoos and conditioners designed specifically for keratin-treated hair. Regular shampoos that contain sulfates can strip away the keratin and shorten the lifespan of the treatment. By investing in hair products that are suitable for keratin-treated hair, you can help prolong the effects and maintain the smoothness for an extended period.

Environmental Factors

The environment can also play a role in how long Brazilian keratin treatment lasts. Excessive exposure to sun, chlorine, saltwater, and other environmental elements can cause the treatment to fade quicker. It's important to protect your hair from these factors by wearing a hat or using hair products with UV protection when spending time outdoors. Additionally, if you swim frequently, wearing a swim cap can help reduce the exposure of your hair to chlorine and saltwater, preserving the treatment for longer.

Moreover, the use of heat styling tools can impact the durability of the treatment. High levels of heat can gradually break down the keratin, leading to the loss of its effects. Therefore, it's crucial to use heat protectant sprays and avoid excessive use of straighteners and curling irons.

The Lifespan of Brazilian Keratin Treatment

Now that we have explored the factors that influence the duration of Brazilian keratin treatment, let's discuss the average lifespan of this hair-transforming procedure. On average, Brazilian keratin treatment can last between 3 to 6 months. This timeframe can vary depending on the factors mentioned earlier, such as hair type, aftercare, and environmental elements.

It's important to note that the treatment does not completely wash out of the hair over time. Instead, it gradually fades away, and you may notice a return of your natural hair texture and frizz. However, the speed at which this occurs can differ from person to person. Some may experience a gradual return to their pre-treatment hair within 3 months, while others may enjoy the effects for up to 6 months.

Considering a Retouch

If you find that the effects of Brazilian keratin treatment are diminishing and you are longing for that silky smoothness again, you have the option of getting a retouch or a second treatment. A retouch involves reapplying the keratin formula to the new hair growth and going through the sealing process once more. This helps to replenish the keratin in the hair shaft and extend the smooth and manageable effects.

Retouching the treatment can help prolong the results and maintain the sleekness of your hair. However, it's important to consult with your stylist before scheduling a retouch. They will assess the condition of your hair and advise you on the best course of action.


In conclusion, Brazilian keratin treatment is a hair-transforming procedure that can provide you with silky smooth and manageable hair. However, the duration of the treatment's effects can vary depending on factors such as hair type, aftercare, and environmental elements. Coarser hair tends to retain the treatment for longer periods, while finer hair may experience a shorter lifespan.

Proper aftercare and maintenance, including the use of sulfate-free hair products and protection from environmental factors, can help extend the life of the treatment. On average, Brazilian keratin treatment lasts between 3 to 6 months, gradually fading away over time. If desired, a retouch can be done to replenish the keratin and prolong the desired effects.

Now armed with a better understanding of Brazilian keratin treatment, you can make an informed decision and enjoy the benefits of this hair-transforming procedure. Say goodbye to frizz and hello to sleek, manageable locks that will turn heads wherever you go.
