About allergy to hair colour
Many hair colorants contain ingredients that can cause an allergic reaction. 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. Y
our 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. Assessing the risk of reaction
Colourstart contains a small amount of PPD, many times less than used in a typical hair colour. It works by exposing the skin to the PPD in the test. Once Colourstart is on your skin, you will see one patch square marked
“A+”, which is the active patch containing PPD and one clear patch square marked “A-”, which is the control patch with no PPD allergen. If the test is positive, indicating potential allergy to hair colorant, the area under the patch marked A+ will look different to that marked A-. If you do have a reaction, you should not use hair colorant, Please see the Patient Information Leaflet (PIL). OPENING HOURS - Mon - Sat (excluding Bank Holidays)
