You can use a semi-permanent, vegetable dye close to natural color to hide the ombre. You can request highlights to blend the color if you don’t want a blanket color all over, although you would need a lot to break up the blonde and they will fade very quickly. If you don’t want to get rid of the blonde, you can try a toner to fade-out and disguise the blunt line but be aware that toners don’t last very long. People with wavy or curly hair are likely to get the best results from at-home ombre as the line is more obvious on straight locks. It is recommended to work with your hair’s natural movement and twist strands after applying the color to avoid a harsh line.
