## Before you buy

- Listing details are inconsistent: the title and colour field identify Dark Brown, while the description calls the shade “Dark Brown Black”, it also claims a no-mix, ready-to-use application, but the directions say to mix colour base and developer. Confirm the selected pack and follow its supplied instructions, the five-minute claim is the stated processing time, not a guaranteed result. The safety text says for external use only, avoid eye contact, and keep away from naked flame or direct heat.

## Customer feedback

Customer feedback describes effective grey coverage and a natural-looking result, with the five-minute application viewed as convenient. Experiences with shade accuracy, coverage and longevity are mixed: some report darker-than-expected colour or fading. Reports of burning and itching make skin comfort an important consideration, while opinions on removal and value also vary. The aggregate rating is 4.4 out of 5 from 30,429 ratings, but it does not establish how well the dye will suit an individual’s colour or skin response.

- Positive themes: Some customers describe the short application time positively.
- Negative themes: Customer feedback includes reports of burning and itching.
- Mixed feedback: Feedback varies on shade, coverage and how long the result lasts.
- Mixed feedback: Opinions differ on value and how easily the colour washes off.
