Shampoos/Conditioners that Protect Hair Color?
Are hair care products really effective in making your hail color last? I can see where a leave-in conditioner with UV protection might help protect it from the sun fading it, but do shampoos and rinse-out conditioners really do anything to protect your chemical hair color? I've tried (been sold) a number of different products that don't seem to me to make any noticeable difference. Any recommendations for products that really do work?
Thanks in advance!
