For vivid colored hair this product is a MUST

This is a pre-wash product. you put it on like a hair mask on your dyed hair for a minimum of 5-7 minutes (I often put it longer) and It creates a protective coat over your hair strands for the wash that allows vivid colors to not fade as quickly! Ever since I started using it, vivids that I needed to reapply every month could easily last 2 months before reapplying. It smells great too and the hair feels great. If you want to dye your hair less frequently this product is a MUST.
