5 /5 Julia Sipll: Joy is an expert with color, and the first time I used her products I could see a dramatic difference. I love that they are ammonia free & clean. Everything I’ve tried (from the line of products she works with) has been a win & reasonably priced. The improvement in the health of my hair says it all. I can’t imagine why I’d ever go back to ammonia-based hair color/ bleach. Highly recommend!
