What to know before buying
- The listing claims colour lasts up to six weeks, but customer feedback reports that it can fade within days. Hair colourants can cause severe allergic reactions.

Avoid use in the listed circumstances, including a previous hair-colour reaction or sensitive, irritated or damaged scalp. Seek medical advice if a reaction occurs or you are unsure.

For buyers choosing this 10-minute comb-in colour, the feedback makes consistent coverage and lasting power the main uncertainties.
