First order, pretty good, 2nd order was absolutely horrendous! No grey coverage, color was totally off from the first. Terrible customer service once I complained. The bottle literally started to explode within 5 min, which did not happen with first order. Not a consistent product. Will never use use this company again. The quality of my hair feels terrible now I am very worried something was seriously wrong with this product that ruined my hair. I have a salon appointment soon to hopefully recover from this disastrous hair product. I'm very experienced at coloring my own hair, this is not something I'm an amateur at so no this was not user error. I have yet to hear back from esalon. DO NOT USE THEM! Just spend the extra money do to a reputable salon!
