What does bleach have on the hair structure?

It gives you're hair a more bleach blonde color depending on what the color was before but it aslo damages your hair very badly. Bleaching your hair is one of the worst things you could do to your hair, in some cases, bleach makes your hair fall out pretty quickly and it makes your hair very dry. Also, when bleaching your hair, it makes your head very itchy and that bleach has to stay on your head for at least an hour. so if your planning to bleach your hair, I would advise that you think about it before you do.
