Can someone tell me the volume of the developer that is in demi permanent colors like Clairol's Natural Instincts? This product is described as being a level 2 that washes out in 28 washes. Thanks.
I have read that it comes with 20vol but with box dyes you can never really know for sure unless you contact the company directly.
when i was hairdressing semi's were usually 10 or 20% depending on the brand

Thank you. Then do you think the volume of the developer of High Lift OTC permanent colors like Colorsilk Luminista would be 30 vol?
I think it would be 30vol from look at it x
High lift permanents are often 40 vol. They best way to be certain is to swap the same amount of your own developer with a known strength.
