Oxidation technology is a common method used in permanent hair dyes to achieve long-lasting color results. Here how it typically works: 1.COLOR DEVELOPMENT: Permanent hair dye formulas contain a combination of dye intermediates and oxidizing agents when mixed together it initiate a chemical reaction. 2.OPENING THE CUTICLE: The first step involves opening the cuticle layer of the hair shaft, the oxidizing agents, typically hydrogen peroxide, act as a developer to penetrate the hair shaft and break down the existing pigment molecules. 3.COLOR FORMATION: Once the cuticle is opened, the dye intermediates penetrate the cortex of the hair shaft. These intermediates then undergo a chemical reaction with the developer to form larger permanent dye molecules. This reaction is often referred as oxidative coupling. 4.LOCKING IN COLOR: The newly formed dye molecules are larger and cannot easily be washed out of the hair shaft. They become trapped within the cortex, proving long- lasting color. 5.CLOSING THE CUTICLE: After the color has develop, the hair cuticle is closed again using a PH-balanced leaving it smooth and shiny hair. Overall, oxidation technology in permanent hair dyes and vibrant color that lasts through multiple washes and gradually fades over time as new hair grows. It's important to note that while effective, these processes can also cause damage to the hair if not done properly or if overused. #AditiSkinHairClinicErode #SkinDocterErode #DermatologistErode
