How to use

Pre-lightened hair gives best colour result — vivid hair colours like Mermaid require pre-lightened (bleached) hair to show accurately on darker natural hair. Complete 48-hour skin patch test before service to check for allergic reaction (PPD-free formulation reduces one common allergen risk but does not eliminate all allergic reaction risk). Apply Classic High Voltage colour directly to clean dry hair from the bottle. Distribute the colour evenly through the hair using a tint brush, ensuring full saturation of each section. Leave to develop per manufacturer instructions (typically 30-45 minutes for full colour intensity). Rinse thoroughly with cool water until water runs clear. Avoid shampooing for 24-48 hours after application to allow colour to set. For maintenance, use colour-safe shampoo and conditioner, wash in cool water, and refresh colour every 4-6 weeks per manufacturer.

For professional and adult use. Complete 48-hour skin patch test before every service to check for allergic reaction — PPD-free formulation reduces one common allergen risk but does not eliminate all allergic reaction risk. Hair colour products contain multiple ingredients that can cause allergic sensitisation, particularly in individuals with previous cosmetic allergies. Do not use if you have previously experienced allergic reaction to hair colour, henna, or black henna. Vivid colour results require pre-lightened hair — on darker unlightened natural hair, colour result will be significantly less vivid than shown, and pre-lightening service should be performed by qualified colourist to minimise natural hair damage. Colour can stain skin, clothing, towels, and bathroom surfaces during and after application — protect all surfaces during application and wear appropriate PPE (gloves, old clothing). Avoid contact with eyes; if contact occurs, rinse thoroughly with water and seek medical attention if irritation persists. Do not apply to eyebrows or eyelashes. Use in a well-ventilated area. Keep out of reach of children. Not for use on damaged, scalp-condition affected, or broken hair without appropriate professional assessment first. Discontinue use and consult a GP if any allergic reaction develops during or after use.
