No, the Brilliant Brunette Visibly Brighter In-Shower Treatment is formulated only for hair lightening within your spectrum of natural tones. For brunettes, if used as directed, it will not leave your hair looking bleached or orange. However, this product will lighten your hair in the warmer direction, just as the sun would do. Our formula is gentler than traditional salon colouring products. However, this is a chemical treatment. Please make sure to read the directions and label warnings prior to use.
