HOYU Lesse Color Treatment 245g (01 Dark Brown / 02 Natural Brown) 10-minute in-bath color treatment that enhances natural-looking hair color with every use. Formulated with sea clay minerals to add body and resilience to the hair while repairing it each time you color. It gently cares for both hair and scalp, providing moisture to aging skin. Unwanted bluish or greenish tones are less likely to remain, and the color fades naturally even after shampooing. Your next hair color will also develop beautifully. Recommended for those who use both salon hair color and color treatments. How to Use: 1. After shampooing, towel-dry the hair thoroughly to remove excess water. 2. Put on gloves and dispense an appropriate amount (about one ping-pong ball–sized amount for short hair) into your hand. Apply evenly over the entire head. Applying in several layers will help achieve a more even, beautiful color. 3. Leave on for about 10 minutes. 4. Rinse thoroughly. Shampooing is not necessary. 5. Dry with a towel you do not mind staining, then dry completely with a hair dryer. For first-time users, using the product continuously for about 5 days (applications) will gradually make gray hair less noticeable. After that, use about 2 to 3 times per week as a guideline. Please note that permed, colored, or damaged areas of hair may absorb more pigment and become darker than intended.
