This is formulated for people with virgin or color-treated black-to-dark-brown hair (levels 1-4) who are seeing unwanted red or brassy undertones from sun, heat, or color fading, and want a toning shampoo rather than a full re-dye.

It's not for grey, white, or lightened (level 5+) hair, since the green pigment can leave a visible greenish cast on lighter hair instead of a neutral tone.

The reason to reach for a color-depositing shampoo like this instead of a regular one is timing: red and brassy tones creep back into dark hair between color appointments, and this lets you tone them down in the shower rather than booking another salon visit. The green-tone approach is straightforward color theory — green sits opposite red on the color wheel, so it cancels the undertone out rather than just masking it with shine additives.

Wear gloves throughout to avoid staining your hands, and keep the lather away from your hairline and skin.

• Apply to wet hair and lather well, avoiding the scalp.
• Leave in for 3-5 minutes for the full toning effect.
• Rinse thoroughly.
• Follow with Dark Envy Conditioner or the Red Neutralization Hair Mask.

Standout points:

• Green pigment directly targets red/brassy tones in dark hair rather than just cleansing
• Doubles as a toner and a shampoo, so no separate toning step is needed between color services
• Fast-acting — full toning effect in 3-5 minutes

Watch-outs:

• Contains Dimethicone, so it's not a match for anyone avoiding silicones
• Not suitable for grey, white, or lightened (level 5+) hair — can leave a green tint
• The dye can stain skin and fabric, so gloves and care around the hairline are needed
