I have been going to Aveda since 2009. The hair color is amazing- as a brunette I could initially go almost 12 weeks between retouches (as a woman in my late 50s the gray has become slightly more stubborn now but still 8 weeks between retouches)
It does require a time commitment, but for me that is off set by the cost and mini facial /hand and arm massage. The staff is friendly and professional and the students are closely monitored.
I had 1 hair mishap in all these years and it was quickly resolved and repaired.
I highly recommend.
