I have used this product for 9 years approximately 20x a year. I know how to dye my hair. I dyed my hair in July the same way I always do. Second bottle of dye seemed warm/hot when I mixed it for the "ends" and exploded all over my bathroom. Hit the wall 9' feet away, stained the wall, my clawfoot tub and my oak flooring. Thank God I had left the room for a minute or it would have probably blown up in my face and blinded me. I contacted eSalon as I researched and saw this is a reoccurring problem with their product. They said all they could do is refund the cost of the kit. No help with repairs. Very cold, computer responses. They know this is happening and are not doing anything to protect their customers.
