## Before you buy

- The listing calls the shade H45 Dark Brown in the colour details but says Dark Brown Black in the title and product description. Confirm the intended shade and match against your existing hair colour before buying.
- The pack instructions call for a 48-hour allergy patch test before each use. The product is not intended for under-16s. Avoid use in the stated circumstances involving irritated or damaged scalp, previous reactions to hair colour or black henna, and skin depigmentation concerns. Avoid eye contact, rinse immediately if contact occurs, do not use on eyelashes or eyebrows, and follow the enclosed instructions.

## A good fit for

- People seeking permanent dark brown colour to cover grey hair.
- Buyers who prefer a short processing time and a liquid shampoo-in application.

## Less suited to

- Anyone who cannot or does not wish to complete the required 48-hour allergy patch test.
- People seeking a gradual grey-reducing colour or a deliberately partial grey look.

## Customer feedback

Customer feedback highlights quick application and reports of grey coverage that looks natural, although opinions differ on how well the dye colours grey and how long results last. Some also describe staining or fading differently, and value assessments are mixed. The five-minute processing time and claimed six-week duration may be useful reference points, but customer experiences do not consistently match the stated longevity.
- Positive themes: Customers report that the dye works quickly and can cover grey without looking artificial.
- Negative themes: Some customers say the colour does not last long.
- Mixed feedback: Feedback differs on grey coverage, how the colour fades or washes out, and whether the product represents good value.
