I've been using this since finding out I am allergic to PPD and TDS. This is the only color I and others like me are able to use. Not only am I thankful for that, I get compliments constantly on my hair condition and color all the time. My hair is naturally black with gray that I cover with Cosamo. As long as I follow my own directions :) it works like a charm and lasts for weeks. Please don't discontinue!!!
My own directions-wash and dry hair using no conditioner or styling products (this has made a big difference). Apply Cosamo, wrap and heat with blow dryer for approx 5-10 minutes, lather & rinse, condition and style. Thanks!
