Extreme Purple Hair Transformation with Overtone! Last time, I used the Purple for Brown Hair Coloring Conditioner, but this time I went bold with Extreme Purple. It has a cooler undertone and a noticeably deeper shade than the purple for brown hair. Both shades are gorgeous, and I love them both. Next time, I might try blending them or adding some highlights for a mix of the two! LTKStyleTip LTKBeauty LTKOver40
