Professional use recommended. Wash the hair with an anti-residue shampoo, emulsify and rinse, repeating if needed, then towel-dry. Divide the hair into four quadrants. Wearing gloves, apply the mask evenly from roots to ends, starting with the most lifted or most porous sections. Leave on for 5 to 15 minutes, checking visually until the tone you want appears. Rinse thoroughly and style as usual. Always carry out a strand test and a patch test beforehand.
- Thick, creamy mask texture in a 500 ml pump bottle; a little goes a long way through mid-lengths and ends
- Contains concentrated direct dyes that can stain skin, nails, towels and surfaces, so gloves and surface protection are essential
The gray direct dyes do the visible work, settling on the outside of the hair fibre to cool warm tones on blondes or deepen the look of dark hair. The creamy fatty-alcohol base holds them in place long enough to develop evenly, while Argan and Ojon oils plus Aloe Vera keep the fibre soft and slippery so pigment spreads smoothly instead of grabbing on porous, over-lightened ends. The result is tone and condition delivered in the same step.

En savoir plusFelps Professional Black 4K Gray Effect Toning Mask – 16.9 fl oz (500 ml) is a professional pigmented toning mask made for anyone chasing a cool, smoky finish instead of warm brassy tones. Loaded with high-quality gray pigments, it deposits colour the moment it meets the hair fibre, so bleached and lightened hair reads ashier and dark hair reads deeper and glossier.
Unlike a simple colour rinse, this mask doubles as a conditioning treatment. A blend of Ojon, Palm and Argan oils with Aloe Vera works alongside the pigments to soften the hair and improve slip, so the tone lands evenly from root to tip instead of grabbing on porous ends.
Developed in Brazil for salon professionals, Black 4K is fully customisable: a few minutes gives a soft ash veil, while a longer development time builds a bolder graphite effect. Rinse out, style as usual, and the new tone is ready to wear.
Key Features:
- Cool Ash Result: High-quality gray pigments help neutralise the appearance of yellow and orange tones in blonde and lightened hair.
- Graphite Depth on Dark Hair: On black and dark brown hair it helps intensify shine and adds a smoky, dimensional finish.
- Adjustable Intensity: Colour builds with time on the hair, from a subtle veil to a strong gray effect.
- Nourishing Oil Blend: Ojon, Palm and Argan oils help condition the fibre while the pigment develops.
- Hydration & Emollience: The creamy mask base helps soften the hair and improve manageability after chemical lightening.
- Luminous Finish: Helps hair look glossier and the colour look more defined.
- Salon Format: A generous 500 ml pump bottle sized for professional back-bar use.
How To Use
