Whether your hair is color-treated or all-natural, you may notice that from time-to-time your color tone needs a bit of adjustment. Many factors can cause our hair color to go from brilliant to blah. This includes air pollution, smoke, sunlight, chemicals (like chlorine from a pool), and even hair styling tools. These factors often cause brunette hair to take on undesirable brassy tones and blonde or grey hair to go yellow.
But there is an easy fix! You can brighten up your tone easily with a blue or purple shampoo. If your hair is color-treated, you can use them to extend the life of your color between visits to the hair salon.
So, which one should you be using?
