What to know before buying
Listing details to confirm
The listing claims up to four weeks of coverage, while customer feedback reports around 4–5 washes. Feedback also describes mixed grey coverage, including reports that the shade can be too dark, so consider the shade match and treat duration as variable. The manufacturer advises against use on highlighted hair, recommends application to dry hair, and says any mixed leftover colour should be discarded because it is effective for only 15 minutes.
Who is it for?
A good fit for
- People looking for a permanent dark-brown root touch-up for grey regrowth between colourings.
- Buyers who prefer a gel colour with a claimed 10-minute application and brush-assisted targeting.
Less suited to
- People with highlighted hair, as the manufacturer does not recommend this product for that use.
- Anyone needing coverage for regrowth beyond three weeks, which exceeds the manufacturer's stated recommendation.

Customer feedback highlights ease of use, speed, quality and natural-looking results, with some customers describing effective coverage of silver roots. However, grey coverage is mixed, and some find the dark shade too dark for their needs. Customers also disagree about value. This matters for a permanent root colour: the claimed four-week coverage is not the same as the reported experience of around 4–5 washes, so shade suitability and expected duration are worth considering.
Positive themes
- Customers describe the colour as effective and easy to use, with a natural appearance mentioned by some.
- Feedback highlights quick development, consistent with the listing's 10-minute application claim.
Mixed feedback
- Grey coverage receives mixed feedback, including reports that the colour is too dark for some users.
- Opinions on value for money are divided.
