It's good you did an allergy patch test. Although many individuals that react to other brands do not react to EcoColors, we still recommend everyone do an allergy patch test before application.EcoColors was formulated with nontoxic in mind. If you have a history of allergies or sensitivities, we always recommend you do the allergy test according to the directions and also have a medical plan in place with your physician before you try the allergy test and Color application. Some allergies develop over time with repeated exposures and allergies aren't to be taken lightly .
