Four patented ingredients are also included to help prevent hair damage. Mix Agent 1 and Agent 2 in your palm, apply evenly to hair, and rinse with lukewarm water after 5 to 10 minutes.

Shampoo and gray coverage in one — the first step in your hair care routine

This color-depositing shampoo is designed to replace your regular shampoo. Simply swap out the shampoo step in your existing hair care routine with this product. No separate dye, conditioner, or treatment needed — one wash covers grays and cares for your scalp at the same time.

Best used in the evening

The color pigments need 5 to 10 minutes to fully absorb into the hair, so it's ideal to use this during your evening shower when you have more time. If you rush through it in the morning, you may not see the full color payoff.

Apply generously and thoroughly

Dispense the shampoo into your palm and work it evenly through your hair, focusing on areas where grays are most visible. Lather, then leave on for 5 to 10 minutes to allow the color to develop. Rinse thoroughly with lukewarm water. Formulated at a mildly acidic pH of 5.5, it minimizes scalp irritation and helps maintain a healthy scalp environment.

Adjust frequency based on your gray coverage needs

When you're first starting out or have more visible grays, use daily or every other day to build up color. Once you've achieved the coverage you want, reduce to 2 to 3 times per week to maintain. Choose Deep Brown for a natural brown tone, or Natural Black for a rich black finish. Enriched with a complex of 12 natural herbal essential oils and 4 patented ingredients to support scalp and hair health.

Patch test before first use

Because this product contains color pigments, if you've experienced scalp sensitivity with hair dyes in the past, a patch test is essential. Apply a small amount behind your ear or on the inside of your arm, and check for any reaction after 48 hours. Rinse thoroughly after each use — insufficient rinsing may contribute to hair loss or discoloration. If the product gets into your eyes, rinse immediately with water. Store away from direct sunlight and out of reach of children.
