Keratin Treatment After Hair Bleaching. How Does It Work?

Even considering the fact that hair bleaching is the best way to achieve the desired platinum blonde hair color, ladies who perform such procedure may also face some negative effects of it. Bleached hair is usually thin, dry and brittle.

How does hair bleaching work?

Hair bleaching is the partial or complete removal of hair pigment. The procedure is carried out both on natural and dyed hair. Resistant coloring agents of hair dyes contain hydrogen peroxide, which covers the hair scales, destroying the pigment. This contributes to the penetration of artificial color into the structure of the hair. After the procedure, some coloring pigments are washed off, and the others remain on the hair for a certain time, after which they slowly washed out.


Right after bleaching, the hair may acquire a yellowish shade due to the lightening background. After the procedure, toning is a must as it’s the only way to achieve a clean platinum blonde or any other shade.


To remove the color from the structure of the hair, the bleaching agent lifts the hair scales, the solution penetrates deep into, oxidizing natural or artificial pigment. Therefore, it’s better to carry out the procedure together with a specialist who will control the bleacher’s action and protect the hair during the treatment.


The end result is individual, since each of us has our own set of pigment. Usually, it’s possible to fully bleach the hair in one session only in the case of light brown and light brown locks. Darker hair will have to be bleached several times in order to become platinum.


Keratin treatment for bleached hair: benefits 

After the bleaching, you have to enrich your hair with keratin to protect the cortex. If you’re going just to apply hair conditioners, they won’t solve this problem, as they just work to moisturize hair and prevent it from getting dry. The only product that will definitely help you in this situation is a keratin treatment for bleached hair.

Experts believe that hair bleaching should come before hair treatment. In this case, the dye is securely sealed in the hair, and your locks retain the vivid shade longer. However, it’s important to remember that the dye used should be as safe as possible, since the it will stay inside the hair for a long time. Bleaching is allowed to be carried out three weeks before keratin treatment.
