30 Hottest Blue Hair Ideas That Are So Trendy in 2024

Chances are, you’ve never had blue hair. It’s not typically a color women choose for a hairstyle, but they simply don’t know how great it can look! Whether it’s a temporary color you’re after or something more long-term, if it’s time for a new look and you’re feeling brave, we’ll show you 30 ways blue hair color can work for you!

How To Dye Your Hair Blue

Blue is one of the most popular vivid hair colors right now. It’s a fun color that can go well with various looks. Punk rock? Geek chic? Ethereal fairy/mermaid? Whatever vibe you’re going for, blue hair can enhance the look.

However, as with most fashion colors, dying your hair blue comes with its own challenges.

Of course, with most hair decisions, going to a professional is ideal. But if you don’t have the time or budget to do so, you can achieve the blue hair look you want on your own. Follow these steps to get the striking blue hair that works best for your hair type and style.

Step 1: Choose Your Dye

Overall, lighter blues complement lighter skin while darker ones look better with darker skin, which is just a general guideline and doesn’t apply 100% of the time. Skin undertone is more important than the shade of your skin when choosing the suitable blue dye for your hair.

If you don’t know your skin’s undertone, you can check out this guide to begin. There are three skin undertones: warm, cool, and neutral.

Warm tones lean toward the peachy/yellow/orange palette, while cools lean more toward bluish tones. Neutral tones fall somewhere in between.

Blue hair tends to look better with cool to neutral skin tones, but that doesn’t mean you have to give up on your hair dreams if you have warmer skin. Blues that are purple-based or green-based can make warmer skin tones stand out.

Step 2: Bleach

How To Dye Your Hair Blue - Bleach

If you’re not naturally a platinum blonde, you will have to bleach your hair first before dyeing it.

Achieving a successful bleach job is essential if you want your blue hair to look great. If areas of your hair don’t get bleached correctly, you may have patches of a greenish color and an overall uneven look.

Ideally, you should let your hair rest for a day or two after bleaching before going in with the blue dye, which should give the hair time to recover and might help you sustain more minor damage to your hair. 

Step 3: Condition

Color processing is hard on your hair, and the following bleach with color is doubly distressing. Deep condition your hair after bleaching to give it a little bit of extra recovery and reduce the risk of damage from the dyeing process.

Step 4: Mix

How To Dye Your Hair Blue - Mix

In a plastic or glass bowl, mix your desired dye and developer according to the package directions. Mixing the dye incorrectly can lead to uneven color, hair damage, and even burns, so be sure to follow the directions carefully while mixing. Mix until the dye is smooth and well-blended before applying.

Step 5: Prepare

Hair dye is messy. Dress in an old t-shirt that you won’t mind staining, and drape a towel around your shoulders to prevent drips. Apply a thin layer of petroleum jelly around your hairline to avoid staining your skin and make smudges easy to clean up. Put on gloves to keep the dye away from your skin and nails while you apply.

Step 6: Apply

How To Dye Your Hair Blue - Apply

Part your hair into at least four sections (or more if it’s extra-long or thick), holding the front sections out of the way with non-metallic clips. Apply the dye evenly with a brush to one section at a time, starting at the back of your neck.

Saturate the hair thoroughly in one section before moving on to the next to ensure even coverage. Continue applying dye until all your hair is thoroughly saturated.

Step 7: Wait

Clip your hair up or cover it with a shower cap to protect your skin and furniture while your hair develops. Follow the package instructions to determine how long to leave the dye on your hair. Check your hair’s progress often to make sure it’s developing properly.

Step 8: Rinse

After the required time has elapsed, rinse your hair thoroughly to get all the dye out. Use lukewarm water to avoid washing the pigment out of your hair. Rinse until the water runs clear, condition, and towel dry gently to avoid further damage.

What Color Can You Dye Your Hair After Blue?

If you’re ready to say bye-bye to blue, choose your new shade wisely! Not every color and type of dye will cover your blue adequately.

Try purple or green if you want to stick with a fantasy color. They both cover blue very well. However, going back to a more natural color after blue is trickier. It’s recommended that you let your blue dye fade to at least some degree before attempting to go for natural color.

Dark auburn, brown, black, or light copper are excellent choices to cover blue. You may need to use permanent hair color to ensure complete coverage. You should visit a hair salon if you want to change a recently done blue dye job drastically.

What Colors Cancel Out Blue Hair?

Orange cancels out blue. If you want to color-correct the blue from your hair, you can use a warm toner and an orange-based dye like copper brown.

How To Get Blue Hair Dye Off Skin

How To Get Blue Hair Dye Off Skin

The first step is avoiding getting it on your skin in the first place. Use petroleum jelly around your hairline and scalp so that the dye doesn’t stain these areas.

Wear gloves while preparing and applying the dye. If dye gets on your skin, you can use a mixture of dishwashing liquid and baking soda to scrub it off. Any remaining color should fade away within a couple of days.


Here are the most commonly asked questions regarding blue hair.

Is blue a natural hair color?

No. Blue hair doesn’t exist in nature for humans, but some shades of black hair can have bluish undertones in sunlight.

Which skin tones go well with blue hair?

As discussed above, cooler and neutral skin tones look better with pure blues, while warm skin tones are complemented by purple or green-based ones. Always test several colors of blue next to your skin before making a final decision.

What to wear with blue hair?

It all depends on what look you’re going for. You can go for contrast colors like orange (if your hair is pure blue) or yellow (if your hair is purple-blue).

If you’re in more of a romantic or cute mood, you can match your pastel blue hair with other pastels like pink or mint green. If in doubt, white and black are neutrals that look good with any hair color.

What color does blue hair fade to?

Blue hair will usually fade to a lighter shade that gets weaker over time until it’s completely gone.

Will blue hair fade fast?

Usually. Like most unnatural “crayon colors,” blue fades relatively fast. About six weeks is the average time.

Is blue hair color high-maintenance?

Yes. Due to its fast fade time and the fact that it looks best when vibrant, this hair color needs substantial upkeep. Blue color-depositing shampoo and conditioner can help extend the life of your color. You can also limit heat styling and harsh chemicals.

Can I dye blue hair without bleach?

Yes and no. You will need to bleach your hair if you want a bright or pastel, and your hair isn’t naturally light pale blonde. If your hair is darker and you don’t want to use bleach, you can still go blue by choosing dark shades like Blue, Black, Navy, and Midnight shade.

Will brown hair dye cover blue?

A coppery-brown dye (preferably permanent) can cover blue. Toning with copper toner may be needed to keep the color from looking greenish.

Does blue hair turn green?

Yes, blue hair can turn green as it fades due to environmental factors, hair products, and other reasons.

Does purple shampoo work on blue hair?

Somewhat. Purple shampoo can keep your hair from going green and help the blue last longer. There is also blue shampoo which would be better suited for the job.

Will blue hair dye cover red?

Not always. Blue hair dye over red hair is likely to result in a purplish or maroon color unless you go with a very dark black-leaning shade of blue.

Are you feeling inspired yet? We’re sure you’re mind is reeling with the number of beautiful ways you can add blue hair color into your current look!
