Colour Maintenance & Aftercare

Wash hair 2–3 times per week to reduce fading.
Use cool or lukewarm water for washing.
Use dry shampoo between washes to preserve colour.
Apply weekly deep conditioning masks to maintain hair health and colour.
Limit heat styling and sun exposure; use heat protectants and UV-care products.

Tips & Warnings
Perform a patch test and strand test before full application.
On darker hair, expect subtle or muted yellow; bleaching gives the best result.
Semi-permanent colour fades over time; touch-ups may be needed.
Pigment can stain skin, towels, clothing, or bedding — wear gloves and use old towels during application.
How To Use
Prepare your hair: For best results, use on clean, dry hair. Lighten your hair if you want the most vibrant results.
Protect your skin and clothes: Wear gloves and apply petroleum jelly or moisturizer around your hairline and ears to avoid staining.
Apply the color: Squeeze the cream directly onto your hair and work through evenly using a comb or your fingers.
Processing time: Leave the color on for 30-45 minutes, depending on desired intensity.
Rinse thoroughly: Rinse hair with lukewarm water until water runs clear. Avoid shampooing immediately to allow the color to set.
Style as usual: Blow-dry or air dry and enjoy your vibrant new look!
