Dexe Black Hair Shampoo – 400ml

Product Overview

Dexe Black Hair Shampoo is a hair colourant packaged and applied like a shampoo. The seller’s own description calls it a “shampoo type hair dye” and a “two in one”, and that is exactly right: you lather it into the hair, leave it on for five minutes (the small print allows up to 10-15 for stubborn grey), and rinse.

The appeal is obvious — it removes the mixing, the sectioning and the hour in a chair. The trade-off is that it is still a dye, with everything that implies, and the format makes it easy to forget that.

Important — This Is a Hair Dye, Not a Shampoo

It is sold in a shampoo bottle and used like one, but the product is a colourant. It works by depositing dye onto the hair while it sits, which is why it needs five to fifteen minutes on the head rather than the thirty seconds of an ordinary wash, and why gloves are supplied.

That means it carries every precaution a hair dye carries.

Allergy Alert — Do the 48-Hour Test Every Time

1. Put a small amount behind the ear or on the inner elbow and let it dry uncovered.
2. Leave it 48 hours without washing the area.
3. If there is any redness, itching, burning, swelling or rash at any point, do not use the product.

Do this before every application, not only the first. Dye allergy can appear suddenly after years of trouble-free use, and each reaction is more severe than the last. In rare cases it swells the face and airway badly enough to need hospital treatment.

• Never use it on eyebrows or eyelashes — it can cause serious eye injury.
• Wear the gloves supplied. It stains skin and nails.
• Do not use it on a broken, sore or irritated scalp.
• Never leave it on longer than the instructions say.
• Rinse immediately with cool water if the scalp burns or stings.
• Get medical help straight away if the face or scalp swells, or breathing becomes difficult.
• Keep out of reach of children.

What to Expect

Colour that builds. A single wash usually darkens grey rather than blacking it out completely; two or three applications close together give fuller coverage. It fades over a couple of weeks and is topped up rather than reapplied from scratch.

It is a colourant, so the hair it dyes stays dyed until it grows out or fades. Roots will show as they grow — that is normal and is what the top-ups are for.

Frequently Asked Questions

How often can I use it?

Every one to two weeks for maintenance. Using a dye more often than that builds up on the length and looks flat and dull.

Does it clean hair like a normal shampoo?

It lathers and cleans, but it is a colourant first. Most people wash normally with an ordinary shampoo between applications.

Will it stain my pillow?

It can for the first night or two, especially if the hair is not rinsed until the water runs completely clear. Rinse thoroughly and use a dark pillowcase to begin with.

How should I store it?

Somewhere cool and dry with the cap closed. A shelf away from the shower spray is better than one in it — constant heat and steam shorten the life of any formula.
