How many times will i need to bleach my hair if my natural hair colour is black?

I'm just wondering how many packs of bleach i will get through.How many times will i need to bleach my hair if my natural hair colour is black?
to get the reddish purple to its most vibrant you dont need to bleach your hair until its white, a orangy yellow will do. i suggest going to Sally's and getting a big bottle of 30% vol peroxide and a big pack of bleach, cost me like 拢7 and it lasts to about 50 applications or even more. so if you run out of bleach you can always mix up another batch and you will be able to use it if you want to bleach your hair in the future. it will be much easier, cheaper, more practical and safer than using the individual packs. good luck!How many times will i need to bleach my hair if my natural hair colour is black?
i'm thinking about 3. use 40 volume the first time, mix 30 and 40 evenly the second time and use 30 the third time. after the second bleaching, you will really notice that your roots will be a lighter yellow than the lengths of your hair. this is from the heat of your scalp making the bleach work faster. so for the third time, don't apply bleach to your roots again, it will cause them to turn white and result in an uneven blonde color. it should make your hair a really light yellow, which is the perfect color for toning after. toner is a mild, permanent dye that is meant to be used on hair that has just been bleached to achieve a more natural, true blonde and not so fakey yellow. go to sally beauty to get all your bleach and while you're there, get some wella color charm toner, it's the best i've ever used. it comes in 2 ounces and requires 4 ounces of 20 volume peroxide so you will also need to get a small bottle of 20, reusable gloves that you can also use when you bleach and an applicator bottle to hold the toner. apply it to your hair immediatley after you shampoo out the last wave of bleach, while your hair is damp and leave it on for 30 minutes and it will give you a nice, light natural blonde color with no further damage. while you're at sally's, look for the ardell color/bleach additives. you add them to bleach and dyes and they prevent hair from turning too orange/yellow/gold during the bleaching process and remove existing brassy tones in hair when added to toner or dye. look for the unred, red gold corrector plus and lock-in blonde. add unred and red gold to your bleach every time you bleach and add all 3 to your toner. unred and lock-in blonde require 10 drops per every ounce of peroxide used and red gold requires 15 for every ounce.





just a few tips for you to get great looking blonde. good luck!





edit - toning your hair after you bleach it will help your purple color come out the color you want. if it's too yellow it won't look like the exact color you're trying to go for. so when you pick a toner, get the ';white lady'; shade, it will make the purple come out great.
my friend's hair colour is black. she wanted to dye her hair electric blue, but told by her hairdresser by the time her hairs been bleached enough, it'll be straw if not fallen out, due to the natural darkness of her hair.
Depends on how long and thick your hair it. If it is think below the shoulder (around mid-back) you might need 3. Anything less, no more than 2.
You should go to a salon.. However your hair will never be blonde like a ';white girl's'; because the type of hair you have.





Your hair will 99.9% come out orange
dont use bleach, its really bad , use color instead, its long lasting and good try it.........
