How many levels does 20 volume developer lift with bleach? This is a common question among individuals who are looking to lighten their hair significantly. The answer to this question depends on several factors, including the natural color of your hair, the condition of your hair, and the desired outcome. In this article, we will explore the effects of using a 20 volume developer with bleach and how it can lift your hair to achieve the desired level of lightness.
Firstly, it is important to understand that the level of lift achieved by a 20 volume developer with bleach is measured in levels. A level system is used to describe the degree of lightening that can be achieved with a particular developer. Typically, a 20 volume developer is considered to be the strongest available, as it contains a high concentration of hydrogen peroxide, which is the active ingredient responsible for the lightening process.
When using a 20 volume developer with bleach, it is generally expected to lift your hair up to 7-8 levels. However, this is not a guaranteed outcome, as individual results may vary. For example, if your hair is already a light shade, you may only achieve a 3-4 level lift. Conversely, if your hair is a dark color, you may be able to achieve the full 7-8 level lift.
It is important to note that using a 20 volume developer with bleach can be quite harsh on your hair, especially if it is not in good condition. The high concentration of hydrogen peroxide can strip your hair of its natural oils and moisture, leading to dryness, breakage, and even scalp irritation. To minimize the risk of damage, it is recommended to use a conditioning treatment or a leave-in conditioner after bleaching your hair.
Additionally, it is crucial to follow the instructions provided by the manufacturer when using a 20 volume developer with bleach. This includes mixing the developer and bleach according to the recommended ratios, applying the mixture evenly to your hair, and timing the process correctly. Over-processing or leaving the mixture on for too long can result in an uneven lift or even hair damage.
In conclusion, a 20 volume developer with bleach can lift your hair up to 7-8 levels, but the actual outcome depends on various factors. To achieve the best results while minimizing the risk of damage, it is important to use the correct ratios, follow the instructions carefully, and take proper care of your hair post-bleaching. Remember that it is always a good idea to consult with a professional hair stylist before attempting to bleach your hair at home.
