Can I get blue hair at home?

Successfully dyeing your own hair blue with box dye depends on the colour your hair is now and the blue hair colour you want to be. Subtle hues are pretty easy to do yourself, but if you want a dramatic change then you’re likely to need to pre-lighten your hair.

If your hair colour now is light brown to blonde (and preferably platinum) – you’ve got a good base on which to try dyeing your hair blue at home. Make sure you match up your hair colour to the chart of the side of your chosen box dye to get the right results.

If your hair colour now is a dark hair colour including dark brown and black – you’ll need to take your base colour up a level or two with bleach. this will give you a lighter base to really make the blue pop. Be careful, bleach can really damage your hair. Follow our guide to hair bleaching to learn how to do it safely.

Reviewers say:

“Amazing! When I bought this product I had red hair!! I stripped, bleached and toned my hair so it was blonde and it worked amazingly. I would say it won’t work unless your hair is blonde. I now have blue hair!”

“The best blue dye I have used without having to bleach my hair first.”

“I bleached my hair right before I used mercury blue. It ended up a bit brighter than the box but all blue and great all over coverage.”

We say:

This is one of Schwartzkopf’s dazzling urban metallic, permanent hair colours so we were expecting intense results. We weren’t disappointed.

We applied this dye on pre-lightened light blonde hair and the effects were pretty dramatic! It’s almost a steel blue colour with it’s shimmery silver tones. There’s a great colour-guide on the box and you’ll need to be blonde to get the box colour. Go for it if you want a blue with metallic tones.

Best blue hair dye for: Cool tones with a metallic shine.

How can I care for my coloured blue hair?

Blue hair dye is like red in that the pigments are larger which means it washes out quick. Even permanent blue hair dye will fade to green eventually.

You can minimise the fade by protecting your hair from heat, sunshine and seat and pool water with the right heat protection sprays that contain UV protection.

Try and wash your hair only once or twice a week max after you’ve dyed your hair.

You can help to make the colour last longer by grabbing some specially formulated blue shampoo and conditioner. We love the Joico brand for colour-lasting effects.

Joico Color Balance Blue Shampoo & Conditioner.

To restore your hair’s elasticity and keep your bonds strong, get yourself a bottle of the miracle potions that is Olaplex No 3 Hair Perfector.

And as always, don’t forget to keep following our top coloured hair care tips in How to look after coloured hair and keep it luscious for longer.
