The Best How Long To Leave Bleach In Hair 40 Vol References
How long should I leave bleach in hair when I am using 20 Vol, 30 Vol & 40 Vol Developer? First of all, we do not recommend you use 40 Vol developer with bleach. If you are using a good quality bleach, (and this includes Ugly Duckling bleaches of course) it will work and lift very well with 20 or 30 Vol Developer.
Peroxide mixed with bleach will open the cuticles of the hair and oxidate the pigment present in the hair, lightening your hair. Peroxide is also used to make permanent hair dye work. It’s used usually on 10 volume preparations for non-lift permanent hair dyes, 20 volume for low-lift and 30 for high lift.
My experience is with powder bleach. So, moot point, really. Once it's dry, it's inactive. If your hair was healthy before the 30 vol and bleach, and not ultra fine, your hair will be “okay” until the bleach becomes inactive. Anytime you put an al...
Okay, never ever leave 40 vol bleach in for longer than 30 minutes. I won't lecture you about the conditioning because you seem to know, as you say. But, you should know RIGHT NOW. I'm not lying, listen to me now. You hair WILL NOT, in case you didn't hear that shouting, it WILL NOT be blonde when you are done.
This does extreme damage to your hair beyond normal bleaching. Each hair type is different and there is no cookie cutter amount of time to leave bleach on hair. Test a few strands of hair first using powder hair bleach and a 20 to 30 level hydrogen peroxide developer in equal parts.

When using bleach, you typically just leave it on until your hair is lightened. Usually it takes about 15-20 minutes for the hair to lighten up, but since your hair is dark brown it might take longer. And honestly I think the manic panic colors suck, but since you bought it you'll just have to embrace it.
I would never ever use 40 vol bleach on hair unless it was extremely resistant and we were trying to achieve several levels of lift. When you say bleach, do you mean a powder bleach or a regular high lift hair color? Those are two different things, 40 vol acts differently when mixed with a color than it does an actual bleach.
Use a 10 volume peroxide in your bleach mixture or dilute a 20 volume peroxide by half. Use this weak bleach to open up your hair for colouring. Bleach this weak causes little damage if left on the hair for a short period of time. Shampoo off after 10 minutes.
40 volume developer is going to be the most damaging to your hair. Luckily, you don’t need 40 volume for most situations. But if you’re going very, very light from dark hair, 40 volume may be the best choice. Be warned that with stronger developers, you may end up with a brassy tint to the resulting color.
To bleach light to medium brown hair, you need 30 volume. For dark brown to black, you need 40 volume, which gives maximal lift. Never go beyond 40 volume—it will burn your scalp and destroy your hair. The strength of your toner should be 10 volume. This deposits color without lift.
