Hi all
How long do you have to leave the dye on during the sensitivity test?
I know when it's permanent they say 48. When I had one done at the hairdressers it was for semi permanent and only had to leave it on 20 mins.
What do you recommend for crazy colour and adore?
I can't speak for Crazy colour but Adore asks for 48 hours, I have a feeling that all of them might be 48 hours to make sure there isn't a delayed reaction.
^I agree^ better to be safer & longer than sorry.
