Never apply dry’s or toners to your hair extensions. Any colouring or toning should be carried out by a professional. Never use anything over 4% when colouring, never apply a permanent colour to the extensions. All colour should be thoroughly rinsed and a treatment applied afterwards.
Never bleach or high lift extensions and DO NOT apply any colour or products to the tip of the hair.
Please Note: If extensions have been toned or coloured they are no longer covered under Spectrum Ones guarantee policy.
