oVertone is effective on all hair types and textures and is curl-friendly! Final color results can vary depending on starting hair color (e.g. if your hair is brown, the final color result of Vibrant Red will look much more muted on your strands than it would on a platinum blonde head of hair). Be sure to read the info below the “Will it work on my hair?” icon on all of out Coloring Conditioner product pages to determine if your chosen shade will be effective. We also provide strand photos on every product page to help clients visualize their individual results.
