Given the above summary, write a detailed text in English for it.
In a clean bowl, put in equal amounts of bleach, shampoo, and a creme developer. Mix them together. You can get developer at a beauty store, drug store, or wherever you purchased your hair dye. Get your hair wet, and towel dry it lightly before putting on the mixture. Put on gloves before handling the mixture. Starting at the roots, work the mixture down your hair. Leave the mixture on your hair under a shower cap for about ten minutes. Do not leave it on for too long or you may damage your hair. If you don't have a shower cap, you can also cover your hair with plastic wrap. Use cool water to rinse out the soap cap. Condition your hair afterwards to prevent breakage and damage. You may want to apply a deep conditioning hair mask.
