- The listing says no mixing is required and shampoo removes the product after 10 minutes.
- The stated colour duration is up to six weeks, or until grey regrows.
- The product is described as ammonia-free.

## Pros

## Before you buy

- The listing calls the product both temporary and a hair colour lasting up to six weeks, so permanence and wear expectations are not fully consistent. Shade naming also varies between A-10 Blond, Blonde A10 and Sandy Blonde. Check the selected pack’s shade and instructions before use. Hair colourants can cause severe allergic reactions. Follow the enclosed directions, perform the stated skin allergy alert test 48 hours before each use, avoid use in the listed situations, and do not use on eyebrows or eyelashes.

## A good fit for

- Buyers wanting a comb-in hair colour aimed at covering grey in a blonde shade.
- People who prefer a no-mix product with a stated 10-minute application.

## Less suited to

- Buyers who need a guaranteed shade match or consistent results, given reported mixed colour and effectiveness experiences.
- Anyone unwilling or unable to follow the hair-colour allergy precautions and patch-test directions.

## Customer feedback

Customer feedback highlights ease of application and a natural-looking result, but reports on effectiveness, shade, quality and value are mixed. Some say it works well, while others describe no effect or a darker-than-expected colour. That matters if you need dependable grey coverage or a precise blonde match. The listing’s comb-in method and claimed short application time describe the intended process, not a guarantee of the result.
- Positive themes: Customers describe it as easy to apply and some appreciate its natural-looking result.
- Negative themes: Some customers report no effect and say the shade is darker than expected.
- Mixed feedback: Feedback is divided on effectiveness, colour outcome, quality and value for money.
