How long does a keratin treatment last

Before I commit to answering the question of “How long does a keratin treatment last”, here are a few considerations.

Are you washing your hair with a sulfate free shampoo?

If you want your keratin treatment to last, the first rule of thumb is to make sure you’re using a sulfate free shampoo. A shampoo with a high concentration of Sodium Laurel Sulfate will wash the keratin out faster than a sulfate free shampoo. If you’re used to washing your hair everyday, you may be pulling more keratin from the hair than someone who washes less.

Some people have better luck than others depending on porosity, volume, or whether the hair is fine or thick. 

If you have hair that’s super thick, chances are, you’re keratin treatment may not last as long as someone with fine hair.

If your hair is colored, chances are your keratin treatment might last longer than someone who hasn’t colored their hair.

At the salon today, Jennifer asked me, “How long will this keratin treatment last?” Jennifer likes to wash her hair everyday, but I cautioned that such a practice might do her more a disservice than she might think. She could be washing out the keratin from her hair sooner than what it might be worth to keep it super clean. 

Preserving your keratin treated hair could solely depends on how much you’re shampooing, coloring, blowdrying, or flat ironing your hair. Treat it delicately and you could count on healthier, smoother and silkier hair for a longer period of time.

Keratin treatments usually last anywhere from 3 to 4 months. If you get a keratin treatment on a regular basis, they could last up to 6 months with a keratin buildup.
