Uses:Creates a rich long-lasting color spectrum to achieve an extra-light, natural-looking shiny blonde haircolor. Care Supreme Conditioner helps lock in first day color vibrancy and keeps hair silky and resilient week after week. From roots to ends, color won't fade-out, turn dull or brassy. LB01 is a pale, cool extra light blonde shade with ash tones, which will minimize red/orange tones. For optimal color results, use on light blonde to light brown hair. Not recommended for use on hair previously colored to a shade darker than blonde. Do not use a pre-lightener before using Les Blondissimes. On red hair, your color results will be blonde with gold tones.
