How to Use High Lift Hair Color. The most popular misconception surrounding high lift hair color is that it is dramatically less damaging than bleach. This is not completely true though. The damage of a high lift dye or bleach are roughly equivalent, and this shouldn't be the primary factor used to determine which product you use. When you lighten hair with dye or bleach, it is the oxidation from the developer that is causing your hair to lighten. It does this through a chemical reaction with the melanin pigment that is inside each hair. This melanin is what gives your hair its natural color, and by discoloring it with oxidation, your hair becomes lighter.
Damage to your hair isn't a result of the use of bleach or dye itself though. The damage that occurs is a side effect of the oxidation process that is occurring inside the hair shaft. Whilst oxidation is necessary to lighten melanin and activate the dye molecules so that they become permanent, this oxidation also affects the structure of your hair. When the keratin protein comprising your hair structure is oxidized, it weakens, leading to damaged hair.
From this you can understand that damage to your hair is directly related to the amount of lightening that takes place, through the amount of oxidation. If you were to lighten your hair 3 levels with a high lift dye, or 3 levels with bleach, the amount of damage would be exactly the same because although both products are formulated differently, both work through oxidation. The oxidation lightens your hair, and damages it as a side effect. The main benefit of high lift dye over bleach in this sense is in being less drying and cutting out the additional toning step that bleaching requires. Dryness compounds damage during hair lightening, so anything you do to keep your hair nourished and conditioned during the process will minimize damage.
Bleach is a lot more drying than most high lift dyes.
