Can I dye my hair blue at home?

Successfully dyeing your hair blue at home depends your hair type, the colour your hair is now and the blue hair colour you want it to be.

If your hair is light to dark brown/black– Subtle hues are pretty easy to do yourself, but if you want a dramatic change then you’re going to need to pre-lighten your dark hair.

If your hair is blonde and lighter – you’ll already have a good base for beautiful blue. But if you want to go for pastel blue colours you’ll need to lighten your hair with bleach. Always talk to your hairdresser if you’re not sure!

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

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

We used this on pre-lightened light blonde hair and the effects were pretty dramatic! It’s almost a steel blue colour with its 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.


#1 L’Oreal Paris Colorista Washout Denim Blue Semi-Permanent Hair Colour

q? encoding=UTF8&ASIN=B077N4ZRFH&Format= SL250 &ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=colouredhairc 21&language=en GBloreal semi permanent denim blue hair dye

They say:

  • Denim Blue shade for brunette hair.
  • Chroma-Cream technology in a nourishing hair-mask base.
  • Colours your hair while conditioning at the same time.
  • Long wear – lasts 10-20 shampoos.

Reviewers say:

“Love this colour! I got so many compliments when I first did it. It gave a lovely blue wash tint to my hair. Lasted for around 14 washes. Started as a dark blue and faded a bit over time. Easy to use too.”

“This gave a brilliant strong colour to the ends of my bleach blonde hair. I just dipped the ends in and found that it didn’t dry out my hair just added a brilliant blue colour and moisturised it really well.”

“I had always wanted to try blue hair so I bit the bullet and gave this a try. I think I either need to lighten my hair or leave on for longer as it wasn’t as blue as I would’ve liked. But leaving it on for longer might do the trick!

We say:

L’Oreal Colorista Washouts are semi-permanent dyes perfect for your first dive into blue hair. They’re easy to apply and come with to follow instructions.

This shade is specifically designed for brunette hair, but we found that you’ll need to bleach your hair first if you want the colour on the box. Combine with the Colorista bleach kit for the most vibrant semi-permanent hair colour results.

It gave a lovely blue tone to our medium brown hair. The colour was dark at first which gave a real rich hue. Go for this if you want a subtle, starter blue.

Best for: Beginner blue for warmer tones.

#2 Clairol Colour Crave Semi Permanent Hair Dye, Indigo.

q? encoding=UTF8&ASIN=B072FV4VL8&Format= SL250 &ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=colouredhairc 21&language=en GBclairol color crave indigo

They say:

  • Paint on. Show off.
  • Clairol Color Crave is a semi-permanent colour that lets you flaunt your fearless with bright colours and bold results.
  • Lasts 15+ washes. 

Reviewers say:

“This is far and away the best semi-permanent hair colour I’ve ever tried! It really looks good, the colour was exactly as I was hoping. I would buy it a million more times.”

“While I love semi-permanent hair colour because there is no commitment, I find you don’t get the full benefit of it unless you have naturally light blonde hair. “

“Pretty fun product, not permanent, explore, have fun! This lasted about a month for me, I wash my hair 3 times per week.”

We say:

This is a permanent blue colour with purple hues and as it says on the box – the lighter your hair, the longer your wear. We tried this on light brown hair and found it gave a great purple hair wash, but again, you’d need your hair lightened for a more dramatic look.

It was easy to apply and we left it in longer than the instructions to be sure the colour would take as a few reviews said it didn’t. And it did! The result was a gorgeous, rich deep purple-blue hue. It will fade to red so be prepared to dye it again before long.

Best for: Purple hues for warmer tones.

#3 Clairol Nice’ n Easy Crème, Blue Black Hair Dye.

q? encoding=UTF8&ASIN=B07896CFHW&Format= SL250 &ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=colouredhairc 21&language=en GB

They say:

  • A natural looking permanent home hair colour.
  • It has a blend of 3 tones and highlights and conditioners at every step.
  • Gentle on hair and scalp due to its oil infused colour.
  • It provides 100% grey coverage, with soft and shiny results.
  • No harsh chemicals. Ammonia free.

Reviewers say:

“This product has an easy application and is user friendly. The colour is pretty true to the description. I would definitely recommend it.”

“It left my hair feeling soft and silky not dry at all. I was very pleased with the colour, it lasted for ages.”

“I’ve tried so many brands but I keep coming back to this one. It’s easy to use, and the colours last and looks great. My hair is never dried out after using it.”

We say:

We’re not impressed with the gloves that come with this hair dye so buy your own disposable ones if this is your pick.

This is a dark dark shade of blue and turned pretty much black on our dark brown, dyed hair. It has a subtle blue hue in the light that makes it look shimmery and rich. Use this for long-lasting, deep blue colour.

Best for: Long lasting colour for warm tones.

#4 Schwarzkopf Live Ultra Bright, Turquoise Temptation.

q? encoding=UTF8&ASIN=B00PXYZVM0&Format= SL250 &ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=colouredhairc 21&language=en GBschwartzkopf pastel blue hair color

They say:

  • This no commitment, semi-permanent formula is extremely versatile.
  • For bleached, lightened, highlighted and light blonde hair.
  • The colour result depends upon your natural hair colour.
  • For long or thick hair we recommend using two packs.

Reviewers say:

“I’m so in love with the Schwarzkopf brights range! They provide great colour as long as your hair is lightened to the recommended shade beforehand. For me, they last a heck of a long time.”

“I wasn’t expecting this to work so well, from the middle of the hair to the tips, it’s a gorgeous bluey colour. It covered up orange and pink colours that have been in my hair for more than a year!”

“This colour will last a decent amount of time, not just because blue is a very hard dye to remove, but I think it’ll fade really nicely. I’ll definitely be using it again!”

We say:

This is a bright blue, bold pastel turquoise colour that’s made for light hair. We used it on platinum blonde hair at the ends and it worked a treat.

It’s a little on the green side for a full head of colour, but if you have cool skin tones and want to play with streaks and dips, this is the dye for you.

Best for: Pastel streaks and dips for cool tones.

#5 L’Oréal Colorista Washout Blue Semi-Permanent Hair colour.

q? encoding=UTF8&ASIN=B01NBONJ7F&Format= SL250 &ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=colouredhairc 21&language=en GBloreal semi permananent blue box dye

They say:

  • Fades gradually over 1-2 weeks so you can switch and change your hair colour whenever you want.
  • Based on Chroma-Cream technology in a conditioning hair-mask base.
  • Softly colours your hair while caring at the same time.

Reviewers say:

“I have naturally dark blonde hair but I have it highlighted. I used the blue L’Oréal and absolutely loved the colour! However, I’ve washed my hair a lot and it fades fast.”

“This was so easy and simple to use. Was a little worried as it is very blue when you squeeze out, but left a lovely finish on my hair and lasted near enough a week!”

“Lasted a lot longer than I expected. It was very easy to mix and apply. Smells lovely! Not too bright but can see it and loads of people commented on it, which is a bonus!”

We say:

We tried this box dye on dark blonde hair to create an ombre effect. It was super simple to do and the effect is of a soft, purple/blue pastel colour that we love!

How long it lasts depends on how often you wash your hair. It doesn’t hang around for long so you can afford to experiment. Use it for short-term playfulness.

Best for: Experimenting with colours for cool tones.

#6 Schwarzkopf Live Intense Colour Hair dye, Electric Blue.

q? encoding=UTF8&ASIN=B00PXYZP9E&Format= SL250 &ID=AsinImage&MarketPlace=GB&ServiceVersion=20070822&WS=1&tag=colouredhairc 21&language=en GBschwartzkopf electric blue box dye

They say:

  • Create metallic tones with striking colour intensity
  • Maximum colour depth
  • Anti-fade effect
  • Creates healthy looking, touchably soft hair
  • Vegan ingredients

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 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 blue hair dye colours so we were expecting intense results. We weren’t disappointed.

We used this on pre-lightened light blonde hair and the effects were pretty dramatic! It’s almost a steel blue colour with its 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 for: Cool tones with a metallic shine.

How do I care for my blue hair?

Blue hair is really fun to have. But it can be a hard colour to keep – or get rid of!

To keep your blue hair bright and beautiful for a long time, make sure you use shampoos and conditioners that are specially formulated for coloured hair.

These will stop the colour from fading so fast.

Blue hair will fade to green so you might need to dye your hair more often to keep the blue colour vibrant.

Also try washing your hair less frequently, ideally once a week if you can. You can lengthen the time in between washes with a good dry shampoo.
