Why hair color changes after Brazilian Keratin Treatment ?
Why Hair color changes after a Brazilian keratin treatment, especially if the hair has a history of henna or highlights? Here are the several factors that attributes the changes of it:
-
Chemical Reactions: Brazilian Keratin treatments typically involve the use of chemicals to alter the hair's structure, making it smoother and more manageable. These chemicals can react with the pigments present in the hair, leading to changes in color.
-
Opening of Cuticles: During the brazilian keratin treatment process, the hair's cuticles are opened to allow the keratin to penetrate and bond with the hair shaft. This opening of the cuticles can cause existing color molecules, including those from henna or highlights, to be released or altered.
-
Fading of Henna: Henna is a natural dye that coats the hair, creating a reddish or orange tint. However, henna is semi-permanent and tends to fade over time. The chemical processes involved in brazilian keratin treatments may accelerate the fading of henna, resulting in a change in hair color.
-
Altering Highlighted Hair: Highlights are achieved by bleaching sections of hair to remove its natural pigment. The brazilian keratin treatment's chemical processes might interact with the remaining pigment in the highlighted hair, leading to a shift in color.
-
Heat Application: Brazilian keratin treatments often involve the use of high heat to seal the keratin into the hair. Excessive heat can cause color fading or changes, particularly in hair that has been chemically treated before.
-
Porosity Changes: Hair with a history of henna or highlights may have increased porosity due to the previous chemical treatments. Highly porous hair can absorb and release color more easily, leading to unpredictable color changes.
-
Incomplete Color Removal: If the hair had a dark or intense color from henna or previous highlights, the brazilian keratin treatment might not entirely remove all the color molecules. As a result, residual color may mix with the natural color, producing a different hue.
-
Reaction with Keratin Product: Some brazilian keratin treatments may contain ingredients that interact with specific hair colors, leading to changes in tone or shade.
It's important to note that the extent and nature of color changes can vary depending on the individual's hair type, the specific brazilian keratin treatment used, and the history of previous color treatments. To minimize unwanted color changes, it's essential to communicate your hair's color history to the stylist or hair care professional before undergoing any chemical treatment. Additionally, conducting a strand test before the full treatment can help predict potential color outcomes.
