Oxygen for hair coloring, activator.
To be mixed with permanent, semi-permanent and bleaching colors.
To obtain a perfect result it is necessary to pay attention to how to dose dye and oxygen.
The most frequent question that is asked in these cases is: how much dye and how much oxygen is needed for a correct dosage?
Generally the ratio for mixing the two components is 1: 1, which means that the dye and hydrogen peroxide must be mixed in the same measure.
Therefore, if you have to use 25 ml of color for regrowth you have to add 25 ml of hydrogen peroxide. But the mixing ratio varies depending on the manufacturer, so you should always check the information on the package to be sure of the dosage to be respected.
Other dosages that you can find in mixing professional dye and oxygen can be the following: Mixing ratio 1: 1.5 - in this case the amount of color must be multiplied by 1.5 in order to obtain milliliters of hydrogen peroxide. An example: if you need 25 ml of color to cover the regrowth you need to add 37.50 ml of hydrogen peroxide.
Mixing ratio 1: 2 - This indication is generally found in very lightening dyes and to calculate the right dose you only need to double the amount of color used to find that of hydrogen peroxide. For example, if you are using 100ml of tincture you need to add 200ml of hydrogen peroxide.
