## Before you buy

- The listing describes the colour as temporary while also claiming it lasts up to six weeks, so permanence and duration are inconsistent. Follow the enclosed leaflet for application and timing. Hair colourants can cause severe allergic reactions. Carry out the specified skin allergy test 48 hours before each use and follow all listed warnings, including not using it on eyelashes or eyebrows.

## A good fit for

- People seeking dark brown hair colour with a comb-in applicator for targeted grey touch-ups.
- Buyers looking for a short, at-home application routine and willing to follow hair-colour safety directions.

## Less suited to

- Anyone who has had a reaction to hair colour or a temporary black henna tattoo, or has an irritated or damaged scalp, unless a doctor advises otherwise.
- Anyone seeking a product specifically described as permanent, since the listing labels it temporary despite its duration claim.

## Customer feedback

Customer feedback highlights ease of use and natural-looking results, while reports on effectiveness, grey coverage, longevity and value are mixed. Some customers also report skin irritation, including blisters and staining. The comb-in design and stated six-week duration may matter to touch-up buyers, but those claims do not ensure uniform coverage or lasting results for every user. The aggregate rating leans positive, but ratings alone do not explain individual experiences.
- Positive themes: Customers are reported to appreciate ease of use and a natural appearance.
- Negative themes: Some customers report that the colour does not work well or cover grey properly.
- Negative themes: Some report colour washing out after a week and skin irritation, including blisters or stained skin.
- Mixed feedback: Effectiveness, coverage, longevity and value for money receive mixed feedback.
