This is ammonia free. After many years of coloring my hair and swimming in a clorine pool, the ends were all crinkly. I cut them all off and vowed to change hair coloring. This hair coloring does not damage and it colors grey for about 6-7 washings. As my hair is growing, it is soft, shiny. Also suggest to use alcohol hair spray. Hair is looking good....thanks revlon..I am 73 years old
