A 20 volume developer will be sufficient for coloring facial hair, especially if there are some grays mixed in.
40 volume developer is used for high lift shades and will lift hair 4 levels. 20 volume developer is also used for lifting but will only lift 2 levels. 20 volume is used as well when going darker or for gray coverage as it lifts and deposits at the same time.
I believe 1.5 parts would be 1.5 ounces of developer to 4 ounces of color, which doesn't seem like enough developer. Double check the directions. Usually haircolor is either 1:1 or 1:2 ratio. I've never heard of 4:1.5 ratio.
nothing! the only thing is that the ultra chi comes in various colors and the chi is in black. also, the regular chi is the first one to come out so its less advanced than the ultra and the ultra comes with tourmaline plates which is less damaging to your hair aswell.

The difference between 10 and 20 volume developer is the strength or potency of the developer. 20 volume developer is stronger and lifts the hair color more effectively than 10 volume developer. The choice between them depends on the desired level of lift and hair color result.
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.
Mixing equal parts of 20 V. and 40 V. developers will give you an approximate 30 volume developer.
Mixing 20 and 30 volume creme developer will create an unknown volume of developer that falls between 20 and 30. This mixture may alter the expected results when used with hair color products, potentially resulting in unpredictable color outcomes or hair damage. It is generally recommended to use the developer volume specified by the hair color product for the best results.
It is not recommended to double the volume of developer to achieve the desired strength. Using a 10-volume developer when a 20-volume developer is needed can result in uneven hair color or ineffective processing. It is best to use the correct developer volume for the hair color you are using.
30 volume developer will lighten the hair three levels.
20 Volume developer should be used when toning hair.
Mixing 20 volume creme developer with 30 volume creme developer will result in an in-between strength, usually around 25 volume. This may alter the expected outcome of your hair color or chemical process, so it's best to use the correct developer strength recommended for your specific hair product.
No, 20 volume developer and 40 volume developer cannot be mixed to create 20 volume developer. Mixing them will result in a product with a higher volume developer concentration than either of the original solutions. It is not recommended to mix different volumes of developer as it can affect the outcome of your hair treatment.
No you need the powdered bleach with the developer.
Equal parts of 10V. Developer + 20V. Developer= 15 Volume Developer
When used alone, developer will do nothing to the hair. It is made to be mixed with a hair color.
