Colourstart is a clean, convenient and easy to use patch test. The Colourstart pack contains full instructions on how to use the test and what the result can mean. Colourstart can be used to screen for allergy to PPD and you can repeat the Colourstart test if you are switching to a new hair colour product. Participating hair professionals will recognise and accept the Colourstart test result, so you will not need to be screened for allergy before your colour appointment, unlocking walk-in colour appointments.
Many hair colorants contain ingredients that can cause an allergic reaction. One common ingredient in hair colour is para-phenylenediamine (PPD). PPD is the most common cause of reaction to hair colour. To reduce the risk of users experiencing a reaction, many manufacturers of hair colour recommend the use of an Allergy Alert Test before their product is used. If you are allergic to PPD, you should not use hair colour or Colourstart. Your chosen hair colour may not contain PPD, but it may contain ingredients that are similar to PPD and these can also cause an allergic reaction.
