And unless you're going for the brassy look, people typically want to get rid of them. Purple shampoo is the answer.
These shampoos are typically cool shades of purple, blue, and gray, and they help cancel out the warmth that plagues dyed hair over time. Interested in trying one for yourself? Invest in one of the best purple shampoo choices, ahead.
