bleach
You can leave bleach on the hair for up to an hour. After this it will not work. You have to make a fresh batch. The more time that the bleach is out in the air the less time you have to put it on the hair. The ends are dark because there is more of a build up of colour there. You will have to do this on a few separate occasions. Because your hair is black the bleach will take longer to take the colour out. Black changes to red, the orange then blonde, it does take longer to get black out.
Depends on your natural color and if you're going to do it in steps. Dark hair may takes weeks, in steps and light hair colors may only take once.
Take half inch parts. Apply the bleach one inch from you scalp. Till the end are close to your desired shade. Than apply bleach to scalp. The reason for this is bleach works fast next to you body hot, and it will not come out even. We call it hot roots. You should really go to a professional, for this service. Bleach can kill your hair if left on to long.
Yes. Not recommended. You could loose all your hair. Take some hair and put it in a glass and add bleach. It will eventually dissolve the hair. There are many ways to bleach your hair without using household bleach. Go to Walmart... Do not get bleach in your eyes. You could end up seeing "nothing" for the rest of your life...
No, highlights are bleach which is different than color. Color coats the hair, while bleach removes pigmentation from the hair, to take out highlights you have to either color over them, or wait for them to grow out.
If you already have dyed your hair a dark color you need to bleach it out, your hair should turn a blonde yellow color, then bleach it again. Then buy a white hair dye. Then leave that dye in your hair for a good 45 minutes. Then your done! I wouldn't suggest dying your hair again for a very long time because this can be very damaging. And this will work much better if your hair is its natural color.
