Dexe Argan Speedy Hair Colour Shampoo Instant Dark Brown Hair Dye 420ml/14.2 oz
Grey coverage usually means gloves, a bowl, a timer and half an hour you did not plan for. Dexe take a different route: a colouring shampoo you lather in, leave for five minutes, and rinse.
It works as three things at once. It cleanses, it conditions, and it deposits a dark brown shade over grey and white strands. Argan oil sits in the base to keep the hair soft afterwards, and the formula is plant-based and ammonia-free, which is a gentler proposition than a full permanent tint. It is also formulated not to stain skin, so a hairline rinses clean rather than leaving a brown tidemark.
- Dark brown shade, developed in five minutes
- Covers grey and white hair
- Cleanses and conditions in the same step
- Ammonia-free, with argan oil in the base
- 420ml bottle, suitable for men and women
Follow the timings on the pack rather than guessing, and patch test first as you would with any colour.
Worth being clear about what a colouring shampoo is. This deposits colour on the outside of the strand rather than lifting what is already there, so it will not take dark hair lighter, and it fades gradually with washing instead of growing out as a hard line. For holding a shade between proper colours, or keeping grey down without booking anything, that behaviour is the whole appeal.

Application tips
Work it into wet hair in two passes. The first lather cleans; the second is the one that colours, so spread that one deliberately along the parting, round the temples and down the nape where grey usually sits densest.
Comb it through with your fingers to even it out. Rinse when the time is up, and rinse for longer than feels necessary. Wear gloves and use a dark towel.
Results
A soft dark brown across the greys, matched close enough to the surrounding hair that the root line does not announce itself as it comes through. The tone sits flat and natural rather than glossy or reddish.
Because the base conditions while it works, hair feels smoother coming out than it did going in, and the lack of ammonia keeps the usual post-colour roughness off the ends.
