Yes, you can use a 15 volume developer with demi-permanent ammonia-free hair color to cover and blend greys while slightly lifting the base color. The 15 volume developer provides enough lift for subtle color changes and helps the dye penetrate the hair effectively. However, keep in mind that the results may vary based on your hair's porosity and current color. Always perform a strand test to ensure desired results.
No, permanent hair color cannot be made into a demi-permanent color by mixing it with a 10-volume developer. Demi-permanent colors are formulated differently and require specific developers for proper activation and results. Mixing permanent color with a low-volume developer will not change its properties.
Any hair dye with 20 volume developer or higher is permanent.
No probably not.
It won't make it 30. The way developer works is 10 is no lift deposit only and makes hair semi permanent. 20 is 7-10 shades of lift with deposit and makes hair colour permanent. You have to buy 30 volume developer from a sallys beauty supply but 30 is very dangerous for the hair it can damage it severly I recommend sticking to just 20 volume
The ratio of 40 volume creme developer to permanent hair color is typically 1:1. This means you would use the same amount of developer as you do hair color. For example, if you mix 2 ounces of hair color, you would also use 2 ounces of 40 volume creme developer.
The volume of the developer simply tells you how many levels it will lift your hair so since you are using 30 volume, it will lift your natural color 3 levels higher to help the permanent color show better. The volume/color ratio is 1:1 which means however many oz. of haircolor you use, you put the same number of oz of developer. For example: 2oz permanent haircolor: 2oz of developer I hope this helps you! Source: I am a cosmetologist
Mixing 1 oz of 20 volume developer with 1 oz of 10 volume developer results in an effective volume developer somewhere between 10 and 20 volumes. This blend may provide slightly more lift than a 10 volume developer alone but less lift than a 20 volume developer. It is important to consider the hair's condition and desired outcome before using this mixture.
no, manufacturers instrustions tells you not to
Yes, this will work, but I recommend using 20 volume developer instead of 30 volume and watch the hair closely.
Equal parts of 5 volume developer + 15 volume will yield approximately 10 volume.
Yes. The developer needs to be mixed with a color first, such as a permanent color, or hair lightener. I don't recommend you just adding the developer directly to your hair by itself, although I don't think much will happen since it's hydrogen peroxide or it will lighten your hair slightly. Practice precautions.
To make 10 volume developer from 20 volume developer, you can mix equal parts of 20 volume developer and distilled water. For example, mix 1 part of 20 volume developer with 1 part distilled water to create 10 volume developer.
