Hydrogen peroxide is especially popular with hair colour enthusiasts since it’s mostly used to lighten and bleach hair. Dark or brown hair that needs to take up a different colour is treated with it as a bleaching agent. However, it does tend to strip hair of its natural oils - leading to hair becoming extremely dry and straw-like due to loss of lustre and natural hydration. To remedy this, you are recommended to take deep conditioning treatments (keratin or cysteine) in order to re-infuse the nourishment and retain the natural shine and hydration of your hair. You have to be very careful as far as the usage of hydrogen peroxide for hair in any concentration is concerned.
