Can You Use Conditioner As Developer For Bleach. The answer is yes, you can use conditioner instead of a developer to bleach your hair, but it is not recommended. A developer is specifically designed to help lighten hair, while a conditioner does not have the same properties. If you choose to use conditioner instead of developer, your results may not be as good as if you had used the developer. Wet your hair in the shower and towel dry it so that it remains slightly damp.
Start from the middle and go down to the ends, then return to cover the hair near the roots. Simply cover your hair with a shower cap. Mix the bleach powder and peroxide together. Use the ratio the brand suggests, usually 1:2 bleach powder to developer. Then add at least one part shampoo to make it 1:2:1. Increase shampoo to further dilute the bleach if you want lower developer volume. With developer volumes, it’s usually 10 or 20 that is used. Conditioner shouldn’t be mixed with bleach because according to research a conditioner seals the cuticles thus blocking the lightening, but bleach needs those cuticles opened up. You can make a bleach bath using 3 parts of the powder and developer bleach mixture together to 1 part of your shampoo.
