this all really depends on what colour you're planning on going. if you're wanting to go darker u simply put a bottle of ketchup in your hair every night for roughly a week, i know what your thinking ,? but trust me it works this adds the redness for the brown and the natural vitamins will get it in a good condition again as the bleach gets the hair reslly dehydrated. but if ur wanting to go lighter then squeez a lemon in your hair eveyr morning to lighten and then u should put some aqueous cream in everynight o add the moisture and then buy some milk.... i know your all thinking what the hell but i am hairdresser for the past 20 years and I've dyed my hair eveyr colour in the rainbow and i recently had the same problem.
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.
You have to bleach your hair before you dye it, because the bleach lightens your hair. You can't put dye on your hair until it's light, and you cannot mix the two together.
As long as their are no chemicals (such as bleach) in your hair dye, then you can't dye your hair too much. A brand I know, that doesn't have any chemicals in the hair dye, is Manic Panic.
You can dye it with hair products or you can bleach it
Use hair dye, I presume.
Usually, any time after. But you should check the dye and bleach boxes just incase. If you can bleach your hair after, just make sure your hair can handle all of the chemicals.
Yes, hair bleach might work and normal bleach might work. Hair dye is a stain, so it's not permanent.
No if you have a light color you do not thing to bleach it

Most likely, if you used dye, it stands on the package
