Why the concern? I don't know that mine is ceramic but it is ionic. Hubs bought one for me several years ago. We have very hard water. My initial response when I used it the first time was 'you gave me new hair'! At the time felt it made my hair feel softer. In the years since, i use it very infrequently now and my hair is now predominantly grey and a different texture. Not sure if I was still coloring my hair at that point either.
