Frequently asked questions

Will this dye lighten my hair?

No. The directions say semi-permanent colour can make hair darker, keep it at the same level or add tone, but cannot lighten it.

Does it completely cover grey hair?

No. The listing states it does not cover grey hair 100%, so it is better suited to blending than full coverage.

How long does the colour last?

The listing claims it lasts up to 28 washes and fades gradually. Customer feedback is mixed on how long the colour lasts and how well it washes out.

How should I apply it?

The directions say to apply the mixture to dry, unwashed hair, leave it for 20 minutes, then rinse and use the included conditioner. Follow the package directions and allergy-test warning.
