How Long Does a Brazilian Protein Hair Treatment Last?


A Brazilian protein hair treatment, also known as a Brazilian blowout, is a popular salon procedure that promises to transform frizzy and unruly hair into smooth, shiny, and manageable tresses. This revolutionary treatment has gained immense popularity over the years due to its ability to deliver long-lasting results. If you are considering getting a Brazilian protein hair treatment, you might be wondering how long the effects will last. In this article, we will delve into the details of this treatment, its longevity, and provide you with some essential tips for maintaining the results.

Understanding a Brazilian Protein Hair Treatment:

A Brazilian protein hair treatment is a semi-permanent hair straightening method that involves the use of keratin, a protein naturally present in our hair. During the treatment, a formaldehyde-based solution is applied to the hair, which is then sealed with a flat iron. This process helps to relax the hair's natural curls or waves, reduce frizz, and add shine. The keratin fills in the gaps in the hair shaft, resulting in smoother and more manageable strands.

How Long Can You Expect the Results to Last?

The longevity of a Brazilian protein hair treatment varies from person to person, as it depends on several factors, including hair type, texture, and daily hair care routine. On average, the results can last anywhere between 10 to 12 weeks. However, it is essential to note that the treatment gradually fades away over time, and you will start noticing your natural hair texture returning slowly. It is recommended to consult your stylist for a touch-up or reapplication after the initial treatment wears off completely.

Factors that Affect the Longevity of the Treatment:

1. Hair Type: The natural hair type plays a significant role in determining how long the Brazilian protein hair treatment will last. People with coarser, thicker hair might experience longer-lasting results compared to those with finer or thinner hair.

2. Maintenance Routine: The way you care for your hair post-treatment can also impact its longevity. Using sulfate-free shampoos and conditioners specifically designed for treated hair, avoiding excessive heat styling, and limiting exposure to chlorine and saltwater can help maintain the treatment's effects.

3. Frequency of Washing: Frequent shampooing can strip away the treatment's benefits quickly. To prolong the results, try to extend the time between washes and use dry shampoo to refresh your hair when necessary.

4. Environmental Factors: Environmental elements such as humidity, pollution, and exposure to UV rays can affect the lifespan of a Brazilian protein hair treatment. Using protective hair products, like serums or leave-in conditioners with UV filters, can help shield your hair from these detrimental factors.

Tips for Maintaining the Results:

To make the most out of your Brazilian protein hair treatment and extend its longevity, follow these tips:

1. Use Sulfate-Free Hair Products: Choose hair care products that are free from sulfates, as these harsh chemicals can strip away the treatment and make your hair more prone to frizz. Opt for gentle, hydrating shampoos and conditioners that are specifically formulated for chemically treated hair.

2. Avoid Heat Styling: Excessive heat styling tools such as flat irons and curling wands can gradually wear down the treatment, causing your hair to revert to its natural state more quickly. If you must use heat, always apply a heat protectant spray and keep the temperature as low as possible.

3. Limit Chlorine and Saltwater Exposure: Chlorine in swimming pools and saltwater from the ocean can be harsh on treated hair. Before swimming, wet your hair with clean water and apply a leave-in conditioner or protective serum to create a barrier. After swimming, rinse your hair thoroughly to remove any residue and apply a deep conditioning treatment.

4. Protect from UV Rays: Prolonged exposure to the sun's rays can cause color fading and damage to chemically treated hair. Whenever you spend time outdoors, protect your hair by wearing a hat or using a leave-in conditioner with UV filters.

5. Schedule Regular Touch-Ups: Depending on how fast your hair grows and how well you maintain the treatment, you may need touch-ups or reapplications every few months. Consult your stylist to determine the ideal time for touch-ups to keep your hair looking sleek and smooth.


A Brazilian protein hair treatment is a fantastic option for those seeking smoother, more manageable hair. While the treatment's effects are not permanent, they can last anywhere from 10 to 12 weeks with proper care and maintenance. By understanding the factors that influence longevity, such as hair type and maintenance routine, and following the tips provided, you can enjoy the benefits of this treatment for an extended period. Remember to consult with your stylist for personalized advice and touch-ups to keep your hair looking fabulous.
