What is a semi-permanent hair colour?
Semi-permanent hair colours allow you to subtly change your hair colour without altering hair structure. Semi-permanent hair dyes gradually fade over time, as you wash your hair. These hair colour options usually last for up to 10 – 12 washes. Semi-permanent hair colours change your hair colour temporarily. These hair dyes do not contain ammonia or hydrogen peroxide (used in hair colouring products for lightening the hair’s natural colour) to coat the hair, hence are considered safe for usage.
