Purple Hair Faded to Blue? Here’s Why – and What to Do

You dyed your hair a gorgeous purple. A couple of weeks later it is looking more… blue. It is a common question – it is even in our FAQs – and the answer is basic colour theory.

Why it happens

To make purple you need blue and red. In any purple shade, the blue undertone is the last to fade – the warmer red side washes out first. So as the colour softens, what is left looks blue.

How to keep it purple for longer

• Top it up every couple of weeks – purples need regular refreshing to stop the fade.
• Check your routine – avoid shampoos and habits that strip colour, and rinse with cool water.
• Use Crazy Color Purple Vibrant Shampoo to keep the tone fresh between dyes.

If you want the blue gone

You have three options, depending on how far you want to go:

1. Remove it: use a sachet of Crazy Color Back to Base remover. It removes unwanted colour and takes your hair back to the shade it was pre-lightened to.
2. Fade it fast: wash with a clarifying shampoo and warm water to fade it to a pastel blue quickly, then let it fade naturally – or ask a hair stylist to remove it.
3. Turn it into something new: apply a pink or red Crazy Color over the pale blue to neutralise the tone – and you end up with a whole new colour.
