Description

  • Semi-permanent: usually fades in around 10–12 washes, though some colours (especially blue, green, and red pigments) can linger longer on bleached or porous hair.
  • No developer needed: the dye is ready to use straight from the bottle.
  • No ammonia or peroxide in the colour cream itself.
  • Works best on very light blonde or pre-lightened hair for vivid results. Darker hair will usually give a subtler tint.

How To Use Crazy Color Hair Dye:

  • Patch test: Test on skin 24–48 hours before use to check for reactions.
  • Strand test: Try on a small section first to see the colour result and fading.
  • Prep hair: Shampoo only (no conditioner), then dry hair. Wear gloves and old clothes.
  • Apply dye:Cover hair evenly section by section and comb through. Leave for:
    • 15–30 mins for normal colour
    • 45–60 mins for brighter colour
  • Rinse: Rinse with cool water until mostly clear. Avoid shampooing for 48–72 hours for longer-lasting colour.

Tips For Longer-Lasting Colour:

  • Wash hair less often.
  • Use sulphate-free shampoo.
  • Use cool water instead of hot.
  • Dry shampoo can help extend time between washes.
  • Heat styling and clarifying shampoos fade colour faster.

Important Warnings:

  • Even though it’s “semi-permanent,” some shades may stain bleached hair for weeks or months.
  • Blues, greens, reds, and black are often the most stubborn pigments.
  • Pastel shades like Marshmallow or Silver usually need hair lifted to a very pale blonde (level 10) to show properly.

Approximate Bottles Needed:

  • Short hair: 1 bottle
  • Medium hair: 2 bottles
  • Long/thick hair: 3–4 bottles
