Do anyone have an opinion on the colour start patch tests? I heard July next year it will be compulsory to patch test every client 48 hour prior to every treatment. So every time they have the treatment done regardless of how many times they have had the treatment ect they must have had a skin sensitivity test prior to the tint. This if is enforced will be murder for clients and business. Unless it is properly enforced within the industry and everyone follows the rule. I currently do this with hd brows patch test (previously colour start) most likely still is but repackaged. I would like to know people's opinions on the colour start patches, if we patch test with those which are not manufactured but the exact tinting brand or are we patch testing for ppd or the individual tint? Hope this makes sense
