Can I dye my hair blue black at home?

Dyeing your hair blue black at home is totally doable. There are a range of brilliant blue black box dyes on the market today that can bless your hair with this must-have colour.

Follow the chart on the side of the box carefully because it depends on the colour your hair is now whether it ends up as the colour you desire.

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

If your hair is blonde and lighter – you’ll already have a good base for getting a more vibrant blue black hue. If you want to go for pastel blue colours or highlights, you’ll need to lighten your hair with bleach. Always talk to your hairdresser if you’re not sure!

Best for: Long lasting deep blue colour.

This is a dark shade of blue black and turned almost black on our dark brown, dyed hair. In the light, it has a subtle blue hue that warms up the black and gives it a beautiful iridescent shine. Use this for long lasting, deep blue colour.


#1 Revlon Colorsilk Beautiful Color, Natural Blue Black 

q? encoding=UTF8&ASIN=B07DGCG78R&Format= SL250 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=colouredhairc 20&language=en USblue black hair dye revlon

They say:

  • Gives 100% gray coverage
  • Formula includes our Revlon 3D Color Gel Technology, which deposits rich, dimensional color that looks natural and lasts.
  • UV Defense helps shield hair color against fading, keeping your shade bright and true

Reviewers say:

“This is a very good product for it’s inexpensive price. But it’s VERY messy; it literally got EVERYWHERE. Also, the conditioner that they provide is not enough for a normal amount of hair, so make sure to have some on hand.”

“The color result? My hair was a light brown. The color literally came out exactly what it said. A rich, dark midnight blueish black. It is gorgeous.”

“This is a true inkwell black with a cool toned blue hue. The color could have not come out better! Sure in normal light to distance or to the natural eye it looks black, but only when you put it under sun light or fluorescent lighting you notice the blue.”

We say:

The first thing we noticed about this particular box dye was that the formula is pretty thick. This makes it easy to apply but also makes your hair feel really soft as the colour sinks in and works its magic.

We tried this on mid brunette hair and the resulting hue is quite subtle. The colour was dark at first – more black than blue – with glints of blue that catch the light and make your hair shimmer. Go for this if you want a subtle, starter blue black.

Best for: Subtle blue hints.

#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 semi permanent 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 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 dark blue black hair colour with purpley-blue undertones 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 easy to apply. We left it in longer for than the instructions to be sure the colour would take as a few reviews said it didn’t. The result was a gorgeous, rich deep purple-blue hue but not as black as the box. Use this if you have dark hair already to add a blue wash.

Best for: Dark hair only.

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

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.

Reviewers say:

“This product has an easy application and is user friendly. The colour is pretty true to 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:

Nice n easy is certainly that. It smells great and wasn’t as messy to apply as some of the other blue black hair dyes on the list.

This is a dark shade of blue black and turned almost black on our dark brown, dyed hair. In the light, it has a subtle blue hue that warms up the black and gives it a beautiful iridescent shine.

Lots of the reviews said the colour kept really well. Best of all, it left our hair feeling in tip top condition. Use this for long lasting, deep blue colour.

Best for: Long lasting deep blue colour.

#4 L’Oreal Paris Feria, Downtown Denim.

q? encoding=UTF8&ASIN=B0751NDS8F&Format= SL250 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=colouredhairc 20&language=en USblue black box dye loreal denim

They say:

  • With L’Oréal Feria hair color, what you see is the shimmer.
  • Multi-Faceted shimmering color with 3X highlights.
  • Delivers intensified, brilliant results.
  • A twist on the traditional and gives edgy hair color.

Reviewers say:

“Absolutely LOVE Feria hair color. It turned out so pretty. Love how there is a shampoo that comes with it and the after conditioner leaving my hair so silky.”

“The shimmer is really good and it didn’t fry my hair.”

“I have been buying L’oreal Feria for over 8 yrs..it’s by far the best hair product than any of the others. The color is true to form and along w/shimmering effects, and staying-in power..it’s the best..now that I’m older, it also, hides my gray hair..love this product!

We say:

We love the Feria Shimmering range, particularly the edgy Glam Grunge colours like Dusty Mauve and Vintage Teal. The reviews mentioned that this came out pretty dark so we tried it on pre-lightened brunette hair.

We also left it on for 10 mins more than the recommended 25 minutes, but could see it working from the start. It is quite black that’s true. But the colour is not too harsh against cool skin tones.

The blue richness adds softness and depth. And there is definitely a shimmer and gloss at first but don’t expect it to last beyond the first wash! Don’t go for this if your base colour is dark as it might be too black.

Best for: Shimmering colour for lighter bases.

#5 L’Oréal Colorista Semi-Permanent Hair Dye, Midnight Blue/Denim.

q? encoding=UTF8&ASIN=B074K73BH9&Format= SL250 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=colouredhairc 20&language=en UScolorista midnight blue denim

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:

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 and it does come out blue-black but more on the blue side. It’s semi-permanent so will become bluer with each wash. So if you’re looking for more blue than black, this is the box dye for you.

Best for: A bluer hue.

#6 Garnier Nutrisse, Intense Blue Black.

q? encoding=UTF8&ASIN=B0194HSMM2&Format= SL250 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=colouredhairc 20&language=en USblue black color garnier nutrisse

They say:

  • Best for anyone with natural hair between light brown and black.
  • Nourishes with grape seed and avocado oil.
  • Penetrates deep into hair fibers to nourish and condition your hair.
  • Delivers rich, long-lasting color with 100% gray coverage.

Reviewers say:

“This product is amazing! I bought this dye with very high hopes, and it delivered! I have very thick, very dark brown hair, so the color immediately took and looks fantastic.”

“The resulting color is a gorgeous, glossy black with awesome blue tints that are extremely noticeable in the light.”

“My hair is shiny, smells nice, and looks healthier than it did before dyeing. I am pleased and feel sexy with my new hair, I’m hoping it doesn’t fade too quickly!”

We say:

We were excited to try this Intense Blue Black colour as it’s a gorgeous deep blueberry shade on the box. We tried this on dark brown hair to give some shine and lustre and it certainly did that!

Nutrisse hair dyes are great as they don’t smell strongly of ammonia which makes it pleasant to put on. The dye is very blue! But we left it in as instructed and the results were fab. The blue is a cool almost metallic blue that shines and shows the most in your natural highlights. Some of the reviews said it didn’t last too long however.

Best for: Shine and lustre.
