Thanks for posting your experience.
I wonder if it depends on the actual color of your hair color? Mine is dark. Maybe the lighter colored people are not seeing as much fading.
I had my hair colored about 10 days ago (as I said in an earlier post). I am doing kind of a little experiment and not using the WEN as much as I did last month. I am using it about twice a week, instead of every day. Since I'm only 10 days out, it's too soon to tell if my color will look better than it did last month. Normally mine starts to fade at about 5 weeks. I also think the longevity of the color depends on the volume used. I am not a hairdresser, but mine tried to explain to me last time that there are different volumes of color, some stronger and more long lasting than others, but tougher and more damaging on the hair.
Any hairdressers out there that can explain that part to me? I am thinking we're all going to get different WEN/fade results based on other factors besides just which WEN we use and how often.
