Crazy Color Semi Permanent Hair Dye and Colour Care

Bold, vivid colour straight from the bottle

This UK-made semi-permanent dye comes in bold, vivid shades and is ready to use straight from the bottle, with no developer to mix. That makes it simple for creative colourists in the salon and for anyone colouring at home. The 100ml dye is vegan, PETA approved and free from PPD and ammonia.

Because it is semi-permanent, the colour is not meant to last forever. It fades gradually with washing, which makes it a good choice if you like to change shade often or want to try a fashion colour without a long-term commitment. Browse more in hair dye and colours.

Understanding your starting level

Hair colour is measured on a scale of levels, from 1 (black) to 10 (the lightest blonde). The lower the number, the darker the hair. This matters because a semi-permanent hair dye adds colour but does not lighten. Whatever is already in the hair shows through the shade you apply.

The brand's guidance is simple:

• For the brightest result, apply it to pre-lightened, bleached blonde hair. The lighter the base, the more vibrant the colour.
• If your hair is level 8 or darker, which covers every level from 8 down to 1, expect a tint rather than a bright shade. On a medium or dark base, the dye will add a tone or a sheen of colour, not a vivid finish.

If you want a true pastel or a neon-bright result, plan to lighten first. A colourist can help you lift to the right level safely and even out any patches, so the new shade takes evenly from root to tip.

Choosing a shade

The 100ml dye comes in a wide choice of vivid shades. When choosing, think about your base:

• On very light, bleached hair, almost any shade will show at full strength, including the softest tones.
• On a golden or yellow base, cool shades such as blue can look slightly green. A purple-toned or pink shade often sits more evenly.
• On darker hair, deep, rich shades will show more than pastels, but the result will still be a tint.

Always test the shade on a small strand first. It shows you how the colour looks on your own hair and how long to leave it on.

Colour-depositing shampoos

Washing is the main reason vivid colour fades, so the brand makes shampoos to partner its semi-permanent range. Each one is 250ml and matched to a colour family.

• Blue Shampoo 250ml: free of ammonia and sulphates. It deposits just enough pigment to refresh blue hair and helps remove unwanted green tones. It works on any of the blue semi-permanent shades, from light, bright Bubblegum Blue to deep Sapphire. The brand describes it as vegan and cruelty-free. For best results, massage it through wet hair from roots to ends and leave it for 2 to 3 minutes so the pigment can transfer.
• Pink Shampoo 250ml: a salt and sulphate free formula that helps preserve bold pink hair. It works with all the pink shades, helps slow fading and helps remove unwanted tones.
• Purple Shampoo 250ml: a hydrating formula that cleans without stripping colour, made to keep purple hair vivid.
• Red Shampoo 250ml: suitable for any of the red shades, and helps remove unwanted tones.

Only the Blue and Pink shampoos are described as sulphate free, and only the Blue Shampoo is described as ammonia free. If those points matter to you, check each label before you buy.

Anti Bleed Spray

Fresh vivid colour can run onto towels, pillowcases and skin. The Anti Bleed Spray 250ml helps seal your colour after dyeing and prevent colour bleed. The brand says it can extend the life of your colour by up to ten extra washes. It won the Vegan Beauty Award and Bronze at the Veggie Awards 2023.

How to choose

• Colour: 100ml semi-permanent dye in bold, vivid shades, with no developer to mix.

How to apply semi permanent hair dye

1. Start with clean hair. Pre-lighten first if you want a bright or pastel result.
2. Do any skin or allergy alert test the pack directs, and test the shade on a small strand.
3. Protect your skin, clothes and surfaces. Wear gloves and apply the dye straight from the bottle, following the pack directions.
4. Make sure every section is well covered, then process for the time given on the pack.
5. Rinse and use the Anti Bleed Spray as directed.
6. Between colours, wash with the matching shampoo to keep the shade fresh.

Aftercare tips

Vivid semi-permanent colour lasts longest when hair is washed less often and rinsed in cool water. Use the matching colour shampoo, and pat hair dry with an old towel for the first few washes, as some colour may still come off. Heat styling can speed up fading, so use a heat protectant when you blow-dry or straighten.

Care and safety

Follow the instructions on every pack, including any skin or allergy alert test before use. Vivid dyes can stain skin, clothing and towels, so protect them before you start. Avoid contact with the eyes.
