Water quality - interestingly enough, the quality of water you regularly wash your hair with has an effect on hair bleach too.This often leads to hair wraps or hoods being used on rather dark hair or where additional lightening is desired. Warmth - the warmer the temperature of the bleach, the more readily it reacts with your hair.For example, there's a significant difference between a powder with boosters or a plain generic powder. Bleach powder - the particular bleach powder you choose to use can dramatically affect how much lightening you're able to achieve.Developer volume - has a fairly linear effect on hair bleaching-higher volume equals more lightening.The opposite situation is resistant hair, which is, as implied, more resistant to bleaching. Porous hair bleaches more readily a lot of the time because the product has an easier time getting inside the hair due to weakened cuticles. Hair porosity - how receptive your hair is to soak up the color in dyes.You can then see that your hair became a dark yellow color which tells you this is correct.Ī number of factors impact the effectiveness of a product when bleaching hair. You can also use the base color as a guide to what level of toner you should be using, and what color you will ultimately be able to reach after toning is complete.Īs an example of how you would go about using this information, if you have identified that your current hair color is a level five, and you can lift it up to three levels reliably with the bleach you've prepared, the lightest level you can reach is an eight. When you bleach your hair, the visible color is stripped away to reveal the base pigment and you can estimate how much lightening has occurred by looking at the base color you've arrived at. Black hair, however, has a deep, dark red base.In blonde hair, the base pigment is anything from pale yellow to golden orange.The color of your natural hair consists of a base pigment underneath the color you actually see, and this contributes to the depth of the color, making it appear dark. Now that you know how the darkness of your hair is categorized, it's helpful to the process of bleaching itself to discuss just what comprises hair depth.
