American Crew Developer 15 Volume 4.5%
American Crew 15 Volume (4.5%) Developer is a professional hair-coloring developer formulated to activate hair color and lightener formulas while providing controlled lift. At **15 volume (4.5 %)**, this developer is designed to gently lift natural pigment up to one to two levels, making it suitable for **depositing color, blending grey, and enhancing tone without excessive lift**.
