This is a professional-grade, semi-permanent hair color treatment designed for tonal correction and enhancing color vibrancy without the use of ammonia or peroxide. Formulated with conditioning ingredients, it deposits rich, reflective color that gradually fades true-to-tone. Ideal for refreshing highlights, toning blondes, or adding sheer tones to natural hair. The Shades EQ line offers versatility for both subtle enhancements and dramatic color shifts, making it a staple for achieving customized, healthy-looking hair color results.
