BLEACH & LIGHTENERS
How Bleaching Works
Bleach strips the pigment from your hair shaft through the process of oxidation. It is impossible to make your hair a lighter shade without the help of a bleaching (or oxidising) agent.
Hydrogen peroxide and ammonia are the most commonly used bleaching agents. They are often mixed together, because when used separately, they are unstable and very slow in lightening the hair. Do not be fooled by manufacturers who use ‘peroxide-free’ labels as a way to promote their products as ‘hair-friendly’. Although these mixtures do not contain peroxide, they will contain another oxidising agent, which can be just as damaging to your strands.
Is bleach good for your hair?
In fact, bleaching even has some advantages: the process plumps your individual hair shafts, often making your hair appear thicker and fuller. Furthermore, if you are light-skinned and have thinning hair, bleaching can disguise the contrast between your hair and patches of bare scalp.
