Will this 7.1 Medium Ash Blonde give me the cool-toned, non-yellow blonde I want, or will it turn warm or brassy?

Yes, the 7.1 Medium Ash Blonde is designed to give a cool-toned, ashy blonde result, which typically has less golden or yellow undertone than a warm or neutral blonde shade. The 'ash' designation means the formula contains pigments intended to counteract warm, orange, or yellow tones. However, achieving the exact cool tone on the box can depend on your starting hair colour. On natural hair that is already within the blonde range, the ashy result is more predictable. If you are covering grey hair, the ash tones generally provide good coverage. The challenge arises on hair that is darker, very porous, or has previous warm-toned colour. On a warm base (e.g., previous golden highlights or brassy tones), the ash pigments may mix with the underlying warmth, potentially resulting in a muted, darker, or slightly greenish tone, rather than a pure ash. For this reason, a strand test is highly recommended if your hair history is complex or your goal is a significant colour shift. This dye is best suited for refreshing existing ash blonde, toning down light warmth, or colouring natural light brown to blonde hair where a cooler result is desired.
