7 Cool Ways to Get Dark Blue Hair in 2025
Dark blue hair blends a rich blue color with your natural dark hair. To get this shade, mix darker shades of green and violet, then apply them to dark hair.
Dark blue hair makes a strong style statement. Many celebrities and influencers, such as Billie Eilish, have made it popular.
Keep in mind that certain dark blue hair dyes are best applied by a professional colorist.
If you want deep blue hair, first lighten your hair. This step helps the dark blue color appear brighter and more vivid.
Dark blue shades look good on all skin tones because you can adjust the color. When you wear this dark denim hair with texture, it highlights its natural shine and depth.
Here are some stunning photos of the top dark blue hair colors this year to inspire you!
#1: Dimensional Black and Dark Blue Highlights
Dark blue is a bold choice to highlight black hair with highlights. This shade, called Cobalt Blue, was created using Joico’s Sapphire Blue color. The deep blue tone looks stunning on natural black hair, especially with a one-length cut that frames your face. To prevent the blue color from fading, wash your hair with a shampoo made for color-treated hair and use cool water.
#2: Deep Ocean Blue
To get a rich deep blue, blend dark shades with bright tones for extra depth. Adding black roots and some lowlights makes the color even deeper. Indoors, the blue may look less noticeable. But outside, it will really pop. This style offers a bold yet subtle look.
#3: Dark and Faded Electric Blue
Choose dark roots that gradually turn into bright electric blue tips. This style looks bold but still relaxed. Darker roots also help new hair growth blend in smoothly and look more natural.
#4: Deep Indigo Blue with Dark Roots
Adding a rich indigo blue with dark roots can brighten your dark hair without needing bleach. Ask your stylist to add a soft blue tint over your current dark shade.
#5: Dark Violet-Blue Hair
Try adding deep violet-blue shades to your hair this winter for a fresh, beautiful style. The purple hues bring cool tones that look great on dark hair and light skin.
#6: Black Hair with Soft Blue Tint
Add a gentle blue tint to your black hair for a fresh look. The blue will catch the sunlight and create a bright shine. If you decide to go back to black hair, no problem. The blue will slowly fade on its own without extra color fixes. This makes this color change easy and worry-free.
#7: Midnight Sky Blue
Midnight sky blue gives your hair a shiny, deep, and rich look. Make sure to include hair care products in your budget. Using quality products helps keep your hair strong and vibrant between salon visits. I recommend the Redken Acidic Bonding Concentrate system for caring for your hair at home.
#8: Very Subtle Blue Tone
If you want to try the fashion color trend without making a big change, start with a soft blue shade. The best part about blue on dark hair is how it looks different in various lights. You will see the color stand out most when you are in bright sunlight.
#9: Dark and Glossy Blue Hair
If you want a new hairstyle, try a deep, shiny blue color at your next salon appointment. Coloring your hair can also make it look glossier. To keep your color bright, use a good quality shampoo and conditioner. I recommend Kevin Murphy Everlasting Wash and Rinse for the best results.
#10: Berry Blue Short Hair
If you want a fast and bold new look, try a fun berry blue shade to add excitement to your short hair. This berry color works best on natural medium to dark hair. If your hair is lighter, the color will appear softer. But if your hair is dark, the berry blue will look deep and will shine brightly in sunlight.
#11: Deep Blue Thick Hair
If your hair is thick and dark, consider changing it to a deep blue for a gentle hint of color. You don’t need to choose a bright or bold shade to refresh your look. To make the blue more visible, ask your stylist to add babylights first. These tiny highlights will help the deep blue stand out better.
#12: Sophisticated Midnight Blue Hair
A sleek bob with a dark, midnight blue hair color creates a stylish and mysterious look. The deep blue shade looks best on women with naturally dark hair. If you want a change from blonde or brown, this blue-black hair dye is a great choice.
#13: Medium-Length Dark Blueberry Color
Dark blue looks amazing on medium-length hair, especially when you keep your dark roots. It creates a rich navy blue shade that stands out beautifully.
#14: Shiny Curly Dark Blue Hair
Dark blue hair inspired by the ocean is a fun way to highlight your hair’s texture and style. This rich color shines beautifully in the light, reflecting the sparkle of the sea.
#15: Amazing Dark Blue on Beautiful Long Hair
This dark blue hair color blends beautifully with your natural black hair. The result is a soft, subtle blue that looks stunning on long, wavy hair.
#16: Sassy Brown to Dark Blue Ombre
If your hair is naturally dark, this brown to deep blue ombre style is perfect for you. The color has a blueberry brunette tone that will look stunning on your hair.
#17: Bold & Vibrant Dark Blue on Short Hair
Is this color blue, dark, or black? It’s actually a mix of all three! Adding a deep blue shade to your short hair creates a stunning bob. This smooth, stylish blue-black hair is perfect if you feel confident and want a classy look.
#18: Marvelous Dark Metallic Blue
If you want something new, try a deep, dark metallic blue. It mixes midnight and navy shades. I love these thick, beautiful waves. Stylist Tessarah says you need patience to get this amazing look because great styles take time!
#19: Electric Dark Neon Blue
Dark neon blue is a bright, bold color you will enjoy. This electric blue hair will grab everyone’s attention. Show off cool mermaid ocean vibes with this stunning look!
#20: Flattering Dark Sapphire Blue
Dark blue works well if your hair is very dark. After coloring it dark blue, try to wash your hair less often to help the color last longer.
#21: Youthful-Looking Dark Navy Blue
This dark navy blue hair looks full of life thanks to its layered cut. To style a deep blue look like this, use a curling iron to make soft, beachy waves. For a rich blue-black color, pick a good dye brand such as Joico.
#22: Trendy Black to Blue Ombre
If you want a new look, try a beautiful blue shade with a dark black to dark blue ombre. First, the hair was colored black. Then, blue was added with the balayage method to create dark blue tips.
#23: Mature Dark Grey and Blue
A smoky dark blue balayage looks stunning when blended with gray tones. These shades together create soft pastel hints. Using semi-permanent hair color makes it much easier to maintain. The best part is the natural dark hair adds depth and contrast to the dark blue color.
#24: Dynamic Dark Royal Blue
Dark royal blue hair is a bold and trendy choice. Not all stylists can do it well. If you want blue hair or any bright color, pick a colorist carefully. Check their past work with strong shades like dark blue before deciding.
