NOMORE Black Colour Shampoo – Semi-Permanent Grey Coverage

Grey coverage that happens while you wash your hair. No mixing, no gloves, no timer, no ruined towels — and no appointment.

Because it's semi-permanent, colour builds gradually over the first few washes and fades softly rather than leaving a hard regrowth line. That makes it considerably more forgiving than a permanent box dye, and much easier to keep up with.

How to use it

1. Do a patch test 48 hours beforehand — see the warning below. This is not optional
2. Wear gloves. Apply to wet hair and work through from roots to ends
3. Leave for five to ten minutes — longer gives deeper colour
4. Rinse until the water runs clear
5. Repeat two or three times in the first week to build the shade, then once a week to maintain it

Important safety information

Hair colourants can cause severe allergic reactions. Always carry out an allergy alert test 48 hours before each use, following the instructions on the pack.

Do not use this product if you have a rash on your face or a sensitive, irritated or damaged scalp, if you have ever had any reaction after colouring your hair, or if you have ever had a reaction to a temporary black henna tattoo. Not for use on anyone under 16.

If you experience itching, burning or swelling during or after use, rinse immediately and seek medical advice.

What to expect

Semi-permanent colour sits on the hair rather than inside it, so it won't lighten your natural colour and it won't lift grey to a lighter shade — it deposits black over it. Coverage on stubborn or coarse grey may take a few applications to look even.

It fades over four to six washes. That's the trade-off for softness and no regrowth line.

Questions we get asked

Will it stain my hands or bath? Wear gloves and rinse the bath straight afterwards. It's black dye.

Can I use it on chemically treated hair? Generally yes, but patch test and start with a shorter processing time.

How often? Once a week to maintain, more often at the start.

Will it cover 100% grey? It softens and darkens it well. Fully resistant grey may need several applications.
