Recommendation: Perform a preliminary patch test according to the following directions prior to each application, even if the client has had color treatments before. Using a cotton-tipped applicator, apply the color mixture to a 1" x 1" patch of clean skin (gently wash with mild soap and water) on the inside of the forearm and leave to process. After 45 minutes, cleanse the area thoroughly with lukewarm water. After 48 hours have passed, examine the test area. If no reaction has occurred during the test or within 48 hours following the patch text, then the shade may be applied to the client. Do not treat the hair if any reaction occurs. This is a precautionary test, and does not mean conclusively that sensitivity or allergies will not occur during treatment. To use: In a bowl mix one part Topchic Lotion with one part Topchic Permanent Hair Color. For virgin application, start with the darkest part of the hair and apply color 1/2 inch from scalp to ends. Wait 5-10 minutes, then apply remaining color to scalp area. Total processing time 30 minutes. Rinse, shampoo and condition with Goldwell color care shampoo and conditioner.
