ATTENTION WHEN DYEING HAIR
Depending on the duration and depth of effect (penetration), hair dye cosmetics can be classified as bleaches, permanent dyes, semi-permanent dyes and temporary dyes in themselves. It is not expected that the hair will be damaged by these products in one-time application, but it can damage the hair due to the application of dye many times, the process is performed with heavy chemicals. The process that causes the most damage to the hair is the process of color opening or bleaching. There are 2 types of bleach: first, those that contain oxygenated water (hydrogen peroxide), which are used more, and second, those that contain zinc formaldehyde sulfoxylate. At high pH (10) degrees in bleach containing hydrogen peroxide, the active agent reacts with the melanin pigment found in the hair cortex, turning the hair lighter. Bleaches are products that are well tolerated in proper use. But in 6-8 weeks December or more frequent applications, loss of protein due to damage to the ends of the hair can cause skin contact dermatitis and allergies.
Permanent hair dyes are the most preferred products on the market. Hair dyes contain around 3-6% hydrogen peroxide and dye (p-Phenylenediamine/PPD or aminophenols) in varying proportions. In order for the dye to enter the hair strand, into the cortex, it must have a high pH (around 10); ammonium or etonolamines are used in dye products. Hydrogen peroxide matches melanin, the dye agent in the hair strand, with both oxides and dye precursor molecules, creating new colored molecules in the hair cortex. After applying permanent hair dyes, the hair color cannot be easily removed with shampoo, it is resistant to high temperature and light. Hair damage caused by the use of these products is not actually due to the dye itself. It is mainly due to the fact that its alkaline components cause swelling in the hair strand and damage to the outer shell (cuticle) of the hair and loss of protein. It is recommended to minimize damage that the permanent dye used is not much lighter or darker than the original hair, as close to the original color of the hair as possible.
Because semi-permanent dyes do not contain amontum and ethanolamine and contain a lower concentration of hydrogen peroxide (2%), of course, they do less damage to the hair compared to permanent dyes. The content of oxygenated water (hydrogen peroxide) found in hair dyes is very critical. As the content of hydrogen peroxide decreases, the rate of entry of the product into the hair strand also decreases, and the dye is cleaned faster than the hair ..For example, semi-permanent hair dyes containing 2% hydrogen peroxide are durable up to 12-14 washes; when the amount of hydrogen peroxide decreases, this number drops to 6-10 washes, and hair dyes that do not contain hydrogen peroxide at all are temporary dyes, and in 1-2 washes, the dye can be cleaned from the hair. Temporary dyes are rather used to reduce grayness in the original hair, cover greying, reduce unwanted shades. These temporary dyes are available on the market in the form of shampoos or creams and are used by applying them to wet, newly shampooed hair and then rinsing.
Permanent dyes damage the outer structure of the hair strand, the cuticle layer, increasing the water permeability of the hair, causing a high degree of protein loss and destructive damage.
Hydrogen peroxide in permanent hair decays is between 3% and 6%. Semi-permanent hair dyes containing 2% hydrogen peroxide should be used to reduce hair damage and avoid bleach that damages hair proteins.
