This hair dye cream does not contain either ammonia or peroxide like most dyes. It is the only cream dye with a high henna content available in Greece. I have allergies to anything that contains ammonia or peroxide, so I cannot use anything else. Henna powder dyes are difficult to prepare and apply, so I avoid them. The result is very good, as the white hairs are adequately covered as long as the waiting time is followed, and the hair becomes shiny and soft. There is almost no chemical reaction. However, this result does not last more than 2-3 washes. It requires regular local touch-ups (for very white tufts). I don't mind this because I know the ingredients are harmless. The scent is pleasant.
