Vidal Sassoon > Runway Red… Throw left over mixture away.”


if you already have lighter hair, then max of 30 minutes is all one treatment can do,


assumption is that colour sets in thirty minutes, so an hour becomes mute or pointless,

there is mention of use quarter amounts at a time, but that may be specific as roots or touch ups ,

that does depend on what color it is now as lighter or darker, if you have darker, and wanted brighter sharper color, you would have lightened /bleached hair first to blonde/ white / gray values as prequel, then added colour .

“Leave on for 30 minutes (or time indicated by your strand test)

Hopefully you will now be less likely to fall for a system that doesn't work. There are systems that can and will bring you rewards but it is imperative that you know what you are buying first.
