How to Tone Down Blonde Hair, According to Colorists

Use a Hair Gloss

You’ve probably heard the terms “glaze” and “gloss” tossed around at your salon, especially if you’re a blonde. While at-home options are on the market, professionals agree that leaving these treatments to the salon professionals is best. “I don’t recommend using at-home products because long term it can cause build up and make it harder to highlight your hair,” Rojas warns.

Visiting a colorist will also allow them to assess your hair thoroughly and pick the best treatment for it. “Let the [salon pro] see if you have yellow or orange tones [to begin],” explains Rez. “When selecting a gloss to tone down the warmth, your colorist must see the predominant tone to cancel out. For yellow tones, use a violet-based gloss. For yellow-orange tones, use a violet-blue gloss to cancel out both. For orange tones, use a blue-based gloss.”

Rez is a fan of the Moroccanoil Color Calypso Liquid Gloss 10.21. “It cancels out unwanted warmth but does not dull or darken hair post-glossing.”
