Setup, Compatibility & Care
Before starting, ensure you have an old towel to protect surfaces and clothing, as semi-permanent dyes can stain. Always perform a patch test 48 hours before full application to check for skin sensitivity. To maintain the Purple Punk shade, use color-safe, sulfate-free shampoos and avoid washing with very hot water, which can accelerate the fading process. If you have previously treated your hair with harsh chemical straighteners or other intense dyes, wait at least two weeks before applying this product to ensure the hair fiber is stable.
