Should I perform an allergy test (patch test)?

Yes, we always recommend you do a sensitivity test before coloring your hair. At least 48 hours beforehand, mix 1 part Radiant Cream Color (a small squeeze) with 1.5 parts Conditioning Color Activator (a few drops). Use a cotton swab to apply a quarter-sized amount to a small patch of skin behind your ear or inside your elbow. Keep dry. Wait 48 hours. If there is no sign of change to the area, then you’re ready to color. Always consult your physician if you have questions or concerns.
