## Before you buy

- The listing gives conflicting longevity claims: up to 32 shampoos in product details and feature copy, but up to 28 washes in the manufacturer Q&A. Customer feedback also varies on shade depth, grey coverage, how long colour lasts and hair condition, so results may not match every user's expectations.
- Follow the packet directions and perform the stated patch test 48 hours before use. The listing describes coverage of first greys but does not establish consistent coverage for more prominent greys.

## A good fit for

- People seeking a semi-permanent red shade and willing to follow the packet instructions and patch-test guidance.
- Buyers interested in an ammonia-free colour product with a conditioning and glossy finish claim.

## Less suited to

- People who need guaranteed grey coverage, a precisely predictable shade result or permanent colour.

## Customer feedback

Customer feedback highlights easy application and a shiny finish, while reports on the final shade, grey coverage, longevity, value and hair condition are mixed. Some users say the colour appears darker than expected, fades after around three weeks or does not cover grey, while others describe good coverage and lasting colour. These differences matter if you need a predictable shade or dependable grey coverage. The feedback aligns with treating the listed longevity as an estimate rather than a guarantee.
- Positive themes: Customers describe the dye as easy to apply.
- Positive themes: Customers appreciate the glossy finish.
- Negative themes: Some customers report that the colour turns out darker than expected.
- Negative themes: Some report inadequate grey coverage, quicker fading or an adverse effect on hair condition.
- Mixed feedback: Reports differ on grey coverage, longevity, value for money and hair condition.
