How do I properly dye my hair w/ bleach?

it really would be best if you get it profesionally bleached so you dont fry your hair off and so you can learn from them and do it yourself next time knowing what your doing How do I use bleach? usually get the powder and mix it with peroxide, read the instructions to see how much of each is needed, a level 20 peoxide will be best for ou because its not too strong Do I have to water it down? no you dont add water to bleach Do I keep the bleach in when I dye my hair? no first you bleach your hair, then wash all the bleach out so your hair is a yellowy-blondish colour dry it, then dye it, and then wash the dye out how long do I keep the bleach in? read the instructions, some say half an hour, some say no longer than 40 minutes, ect and the less time its on, the less damage it will do to your hair Can you buy bleach from big supermarkets ie ASDA/Tesco? If so, How much? yes, expect to pay around $20 and get the powder and peroxide If not, where can I purchase hair bleach? at places like priceline Also. I was wondering, can you buy a pack of hairdye and put bleach on beforehand and then put the hairdye on? thats what your supposed to do bleach, wash it out, dry hair, dye, wash it out, dry hair

and remember, bleach will ruin you hairs strength, health and shine
