On the Bleaching Effect of Hydrogen Peroxide and Baking Soda on Hair
It is said that hydrogen peroxide and baking soda can bleach hair, but what is the reason for it? Try to analyze it today.
Hydrogen peroxide has strong oxidative properties. When it acts on the hair, it can contact the pigment components in the hair. The color of the hair originates from melanin and other pigment substances. The oxygen atom of hydrogen peroxide is highly active and can break the chemical structure of melanin, causing it to degrade or convert into colorless substances. This is the key to bleaching hair.
Baking soda, scientific name sodium bicarbonate. Its mild nature may have two uses in this process. First, it can adjust the pH of the solution. It is suitable for the pH environment and helps hydrogen peroxide to exert its oxidation efficiency more efficiently. If the environment is peracidic or alkaline, it may affect the decomposition rate and oxidative activity of hydrogen peroxide. Second, baking soda may slightly open the stratum corneum of the hair, making it easier for hydrogen peroxide molecules to penetrate into the hair and fully react with pigments.
However, using hydrogen peroxide and baking soda to bleach hair also has disadvantages. Hydrogen peroxide has strong oxidative properties. If the concentration is improper or the action time is too long, it is easy to damage the hair. Causes dry, rough hair, and loses its luster and toughness. And individual hair characteristics are different, and the reactions to the two are different. Or those with sensitive scalp can easily cause scalp discomfort, allergies, etc.
Therefore, if you want to bleach your hair with hydrogen peroxide and baking soda, check their concentration and use, and try it before a small area of hair to see if there are any adverse reactions, so as to avoid damage to the body.
