The duration for how long the effects of a  Keratin treatment lasts depends on a lot of different factors. Some of the common factors are — type of treatment, post-care treatment and hair type. 

Managing frizzy hair can be a lot challenging and Keratin treatment helps in taming that! If you want to know how then keep reading this article to get to know about what all the treatment entails.

About Keratin Treatment

Keratin treatments refer to a semi-permanent hair straightening process. In this process, the hair gets infused with Keratin. It is a protein naturally found in our hair, skin and nails. The treatment works in smoothing out hair cuticles, reduces frizz and enhances shine. 

There are a lot of different types of Keratin treatments available out there including Keratin Complex, Brazilian Blowouts and others. Each different type of hair treatment differs in formulation, duration of results and in their application process.

Keratin Treatment Process

A general Keratin treatment session can last from anywhere between 1.5 to 3 hours. This depends on the thickness and length of hair. During treatment, the stylist first washes the hair and then applies the Keratin formula. 

Afterwards, they blow dry the hair and flat iron for sealing in the treatment. Later, you are likely to be given specific instructions on how to care for your hair in the days following the treatment.

Types Of Treatment

The type of treatment that one gets is a major factor that affects the duration till which the results stay. Here is a list of the three popular types of Keratin treatment that you can get:

Brazilian Blowout

The Brazilian Blowout is one of the most popular Keratin treatments. It lasts around 3 to 4 months. 

Express Treatments

This treatment lasts about 4 - 6 weeks. It is better for those who are looking for a temporary hair smoothening fix. 

Keratin Complex

The Keratin Complex treatment lasts from anywhere around 4 - 6 months. It depends on the hair's texture and post treatment hair care routine.

Other Factors That Affect The Duration Of Results

Here is a list of some other factors which affect the duration for how long the results from your Keratin treatment are going to stay:

Hair Texture

Hair that's naturally coarse or curly tends to benefit a lot more from Keratin treatments. This is because they significantly reduce frizz and make the hair more manageable. However, this type of hair might also see the effects vanish more quickly. This is even more so if the hair gets exposed to humidity.

Condition Of Hair

Healthy hair generally holds on to Keratin treatments longer than damaged or over-processed hair. If your hair health is already compromised then the treatment will not last long. 

For example, if you had previously color-treated your hair and are now looking to reverse damage with Keratin treatment then that won’t work as well. Your hair will return back to its damaged state just a few weeks after Keratin treatment has been done.

Environment And Lifestyle

Environment factors like a highly humid climate causes the hair to both swell and frizz. This makes it harder for the treatment to last. If you happen to live in a humid climate then you will notice your treatment wearing off more sooner. 

Maintenance Of Hair

Getting regular touch-ups helps in maintaining the manageability and smoothness of hair. There are a lot of people who choose to have a Keratin treatment done every 3-6 months in order to keep their hair looking the best. 

Hair Care Routine

The products that you use post treatment also play a major role in how long the results actually last. For example, you can use sulfate free conditioners and shampoos to extend the lifestyle of your treatment.

Importance Of Caring For Your Treated Hair

In order to maximize the longevity of your Keratin treatment, it becomes essential to follow some essential aftercare guidelines. Here are a few tips how you can make your Keratin treatment last longer:

  • Use Sulfate-Free Products 

Sulfates help strip the Keratin from your hair. Hence, using sulfate-free conditioners and shampoos is very important. These products are very gentle  and aid in maintaining the treatment. 

  • Limit Excessive Washing 

You need to wash your hair less frequently. It is recommended that you wash your hair every 3-4 days. The less that you wash your hair, the longer the treatment is going to last for you. 

  • Do Not Use Heat-Styling Products 

Keratin treatment does reduce damage from heat styling. This does not mean that you need to go back to your old habits of heat styling after treatment. Make sure to actively minimize the usage of tools like curling irons and straighteners to get help in preserving the effects of treatment. 

  • Hair Protection 

If you are swimming in chlorinated water or even exposing your hair to harsh conditions of weather, then consider wearing a swimming cap or any other protective gear to shield the hair from damage. 

  • Deal Gently With Your Hair

Consider using a wide toothed comb to avoid aggressive brushing. This is even more so when your hair is wet. It will help in preventing breakage along with maintaining the integrity of your keratin treatment. 

In Conclusion,

Keratin treatments offer a great way of achieving smoother, shiner hair that lasts for a lot of months. While the duration on an average is about 3 - 6 months, there are a lot of factors which influence how long the results last. By following the above mentioned aftercare routines and making lifestyle adjustments, you will be able to enjoy the benefits of doing Keratin treatments for as long as possible. 

If you are ready for a change, then consult a professional stylist to get the best Keratin treatment done for your lifestyle and hair. This will ensure that you step out of the salon with the hair of your dreams.
