## Before you buy

- The product details list Cowboy Copper and identify dark brown hair as suitable, while the broader use description refers to brunette hair and cool, ashy tones. Customer feedback also includes reports of orange results on coloured hair. Shade outcome may vary, so check the selected shade and suitability before use. The six-wash colour duration and 72-hour shine are manufacturer claims, not guaranteed results. Apply with gloves and rinse until the water runs clear. Ingredient details may change, so see the back of the pack for the latest list.

## A good fit for

- Brunettes seeking a temporary colour refresh between colour services.
- Buyers wanting a tinted hair mask with a short, up-to-10-minute application.

## Less suited to

- People seeking grey coverage or a product recommended for bleached hair.
- Anyone seeking permanent colour rather than a shade claimed to fade over washes.

## Customer feedback

Customer feedback highlights glossy shine and softness, with some customers describing the colour’s longevity positively. Colour results and effectiveness are mixed, including reports that the shade turned coloured hair orange and that the product did not work for some. These reports matter for a temporary brunette tint, where the intended tone may not match every starting colour. The listing claims colour for up to six washes, but the feedback does not show that outcome is consistent.

- Positive themes: Some customers describe the colour’s longevity positively.
