Toning blonde hair darker before and after

Use Purple Shampoo and Conditioner

If you are seeking an at-home solution, start with purple shampoo and conditioner.

Best toner to darken blonde hair

"Purple shampoo is great for neutralizing yellow or brassy tones by balancing them with cool pigments," shares Korab. "Use it once or twice a week and leave it on for a few minutes, but avoid overuse to prevent a purple tint."

Rez adds, "You can use the Moroccanoil Purple Shampoo and Conditioner Bundle to tone down blonde hair that pulls yellow tones over time."

However, if your blonde hair looks more orange than yellow, you'll want to avoid purple shampoo and conditioner.

"Even if the purple component tones down the yellow, the orange will pop more, making the color look muddy," Rez explains. "If you see orange and yellow tones, using a gray shampoo is best. The gray shampoo has blue and purple tones, which will address unwanted yellow and orange coloring and tone down the blonde."
