If you’re a brunette, you’re probably wondering if John Frieda Brilliant Brunette Shampoo can really give you the color you want. The company has been around since 1976, and their products can help you keep your hair looking its best. The two shampoos in this line are solid, and both work well to help you achieve the look you want. The first is a deep colour-deepening shampoo, which will deepen your natural color. The second one will gradually lighten it, and both shampoos will work well to protect your natural hair color.
