What’s the right way to apply it so the colour is even and I don’t stain my skin, towels, or bathroom?

Because the product combines a cleansing base with direct dyes, you use it in the shower exactly like a normal shampoo — but with a few precautions. Put on the gloves provided (or any nitrile gloves) before opening the sachet; the coffee pigment stains skin, nails, towels, grout, and shower curtains quickly. Wet hair thoroughly, squeeze the 40 ml contents into your hand, and work it into a foam from roots to ends, making sure every strand is coated. The foaming action helps distribute the tint evenly, which is especially useful for blending first grey hairs. Leave the foam on for 3 minutes if you want a subtle refresh, or up to 10 minutes for a deeper, richer coffee tone; do not exceed 10 minutes. Rinse with lukewarm water until the runoff is completely clear — any residual foam left on the hairline or neck will transfer to towels or pillowcases. After rinsing, blot hair with an old dark towel rather than a light one. Clean any splashes on tiles, grout, or the shower tray immediately with a bathroom cleaner; dried stains are much harder to remove. The aloe vera in the formula leaves hair feeling smoother, so a separate conditioner is optional but can be used if your ends are dry.
