Start with freshly shampooed (no conditioner), towel-dried hair — damp, not dripping. Direct dyes distribute most evenly on a clean surface free of silicone buildup or oils. Section the hair and work methodically from roots to ends, saturating each strand. For freshly bleached or highly porous ends that tend to grab colour intensely and turn muddy or overly dark, dilute the tint 1:1 or 1:2 with a plain white conditioner (no proteins or heavy oils) before applying to those sections only. This reduces pigment load while still depositing a sheer wash of colour.
Wear the gloves provided (or nitrile gloves) and apply a thin barrier of petroleum jelly or a rich cream along the hairline, ears, and neck — direct pigments stain skin quickly and can be stubborn to remove. Once fully applied, comb through gently with a wide-tooth comb to ensure even distribution, then leave for 15–30 minutes depending on desired intensity; longer does not mean permanent, just deeper deposit. Rinse with cool water until it runs clear — no shampoo needed for the first rinse. Follow with a light conditioner if desired. Avoid heat styling for 24 hours to let the cuticle settle and the colour stabilise.
