Finding a true blue-black hair dye that doesn’t fade into a dull brown or wash out after a week is the real challenge. This guide cuts through the options to focus on what actually matters: the depth of the blue undertone, how well it covers gray, and how long the color truly lasts on your hair.

Ready to find a shade that keeps its cool, dimensional finish? Here is our breakdown of the black blue hair dye choices worth your attention this season.
Our Picks at a Glance
How To Choose The Best Black Blue Hair Dye
Blue-black is a finicky shade because your starting hair color changes the result. The main decision is between a permanent formula, which lifts and deposits color for long-term wear, and a demi-permanent or deposit-only option, which is gentler but won’t lighten your hair. Knowing what you want before you start saves you from disappointment.
Match the Formula to Your Hair
Permanent dyes like L’Oreal and Revlon use developers to penetrate the hair shaft, giving you the deepest, longest-lasting color and the strongest gray coverage. Deposit-only powders from Bigen don’t lift your hair at all — they only add color, which is ideal if you want to cover gray or enrich your natural shade without lightening.
Decode Gray Coverage and Longevity
Gray hair is more resistant to color, so not all formulas will cover it fully. Look for claims of “100% gray coverage” if that’s a priority. For longevity, permanent formulas often advertise a few weeks of vibrant color, while demi-permanent shades fade faster. Consider your washing habits, as frequent washing strips color from any formula.

In-Depth Reviews
1. Revlon ColorSilk 12 Natural Blue Black (3-Pack)
Our pick — over 4.5★ from 250+ verified ratings; the strongest balance of quality and price.
A rich blue-black that covers grays completely without the harsh ammonia sting.
This three-pack is the smart buy for anyone who colors regularly and wants a dependable result every time. It delivers full gray coverage, including the tricky hairline, with a formula that skips ammonia in favor of a bond repair complex and vegan keratin. Owners consistently describe the color as rich and vibrant, with hair that feels softer and looks shinier after use.
Value is the standout here, which is why it claims the top spot. Because you get three full kits in one box, you’re set for multiple touch-ups or a full head of color for less than what a single salon visit costs. Buyers praise its glossy finish and weeks-long cool blue tone.
Your starting shade and how often you wash will affect how long the blue lasts. And like most deep dyes, this one can stain skin and surfaces easily — a barrier cream and old clothes are your friends during application. For the price and the quality of color, it’s a reliable repeat purchase for a reason.
Why It Wins
- Three boxes make it an exceptional value for the money
- Ammonia-free with a bond repair complex for softer hair
- 100% gray coverage that reaches the hairline
- Rich, low-fade color that lasts for weeks
Watch Out For
- Stains skin and surfaces easily, so protect both
- The scent is noticeable, and a sensitive scalp may feel a mild burn
Reach for this if: you want a budget-friendly, ammonia-free permanent dye that covers gray fully and leaves hair in better condition.
Think twice if: you have a very sensitive scalp — a few buyers found the smell strong and felt a slight sting on application.
2. AGE beautiful 1B Cool Blue Black Permanent Cream
Salon-grade color that fights thinning and dryness while delivering a cool blue-black.
If your hair is showing signs of aging — thinning, wiry grays, dullness — this formula is built around that specific problem. Biotin, Melanin, Keratin Peptide, and Silk Protein replenish hair’s lost strength and shine. The formula targets thinning, dullness, and other aging signs with its conditioning blend.
It comes from the Zotos Professional line and is tested in a Green Circle Certified Salon by licensed stylists. It provides a cool blue-black tone with up to 8 weeks of 100% gray coverage. Buyers report the color holds up remarkably well — one owner saw it last about a year without using color-safe products, while another notes it stayed true for months even with frequent washing.
The main thing to know is that gray coverage gets mixed feedback — it works for most, but some find it depends on their gray percentage. It’s a 3-ounce tube, so it’s significantly more compact than the Revlon 3-pack, which weighs 9.14 ounces. Pair it with your preferred developer (10 volume for damaged hair) for the best result.
The Salon Upside
- Anti-aging blend with Biotin, keratin, and silk for healthier hair
- 100% gray coverage that lasts up to 8 weeks
- Rich cool blue-black shade with strong color retention
The Home Caveat
- Gray coverage results vary for some users
- Compact 3-ounce tube means you’ll need to buy developer separately
Best for: mature hair that needs conditioning and strengthening while being colored a rich blue-black.
Look elsewhere if: you want an all-in-one kit with developer and gloves included, as this is just the color cream.
3. L’Oreal Paris Superior Preference 2BL Blue Black
A luminous, fade-defying blue-black with a no-drip gel that makes home application mess-free.
This is the pick for anyone who wants that freshly-colored, high-shine salon look without the salon price. The formula uses a concentration of long-lasting dyes in a conditioning gel texture, which means it coats every hair fiber thoroughly and evenly. The included Shine Protect Conditioner, infused with UV Filter and Vitamin E, helps keep that first-day vibrancy locked in.
The no-drip texture is a genuine practical win — it adheres to the hair rather than running down your neck, which owners appreciate for the precision it allows. One enthusiastic review sums up the sentiment: “it covers every inch perfectly and the shine is real!” The shade is a rich blue-black with a glossy, healthy-looking finish.
This kit weighs in at a substantial 9.14 ounces, making it a heavier, more generous application than the compact AGE beautiful tube. It’s a simple, complete kit with permanent color gel, developer crème, conditioner, gloves, and instructions. It maintains radiance for up to 9 weeks, ideal for long-lasting color.
The Verdict: For a glossy, professional-looking blue-black with easy application, this kit delivers a “wow” shine that’s hard to find in a box dye.
The Only Catch: A shorter option, but the fade-defying claim is backed by real-world reports of minimal fading and excellent gray coverage.
4. Schwarzkopf Professional Igora Royal 1-1 Blue Black
The colorist’s go-to for a true-to-tone blue-black that never veers into unwanted reflections.
Some dyes give you a blue-black that fades to a muddy brown or a weird green. This professional tube from Schwarzkopf is known for its consistency, delivering an intense, uniform blue-black with up to 100% white hair coverage. It’s designed for perfect color equalization, even on porous hair that tends to grab color unevenly.
Long-term users report years of consistent, reliable results. It comes in a compact 60-gram tube (1.6 ounces) that keeps well between uses — one owner notes they use about a third of the tube at a time, so it lasts through several touch-ups. Staining is a known trade-off, but it fades from skin within a couple of days.
Remember this is professional color, so you’ll need to mix it with a developer (one user pairs it with peroxide volume 5). The color is intense and glossy with a smooth, professional finish. It stains skin, which is a given for a shade this deep, but it fades from skin within a couple of days.
Trusted Choice: For anyone who knows their color and wants a pro-grade tube that delivers intense, uniform pigment every single time, this is the “my favorite shade of black.”
5. Clairol Natural Instincts 2BB Blue Black (Pack of 2)
A low-chemical demi dye that softens hair and covers stubborn roots without a strong odor.
If you’ve avoided box dyes because of the harsh chemical smell and scalp burn, this is the formula to consider. It’s a demi-permanent dye, which means it gently coats the hair rather than penetrating deeply. The result is a rich color with minimal bleeding that lasts over a month for many users, even with weekly washing.
It’s especially good on salt-and-pepper hair, grabbing roughly 90% of the gray on the first pass. The formula is free of parabens and has what owners describe as a pleasant scent — or no smell at all. It’s paraben-free and comes in a pack of two, giving you a backup for touch-ups.
Since it’s demi-permanent, it won’t lighten hair; it’s for depositing rich black color. It reads more black than a true blue, so if you want an obvious blue undertone, this might not be the pick. A simple 25-minute application is all that’s needed for a natural-looking, low-maintenance color.
Why Choose It
- No scalp burn and no strong chemical odor
- Covers stubborn gray roots effectively (around 90%)
- Color lasts for weeks without heavy fading
Keep In Mind
- The shade leans more black than blue, so don’t expect a vivid blue tint
- Takes a few days to fully rinse out
Choose this for: a gentle, no-sting dye that covers grays and leaves hair soft, with a subtle blue-black finish.
Pick something else if: you want a dramatic blue undertone or need to lighten your natural color.
6. Bigen #59 Oriental Black Permanent Powder (3-Pack)
A gentle powder that deposits rich, lasting black color with no ammonia and no lifting.
This unique powder formula is activated by water, making it a different experience from cream dyes. It’s a deposit-only color, meaning it won’t lift your hair to a lighter shade, but it will deposit rich, natural-looking color into even the most stubborn gray. People with sensitive scalps who find harsher dyes uncomfortable have used this for years without issue.
Because it’s ammonia-free, it’s a gentler choice for your hair and leaves it looking smooth and shiny. The application is straightforward: wash, towel-dry, apply the mix, rinse, and condition. One owner who uses it for facial grays recommends rinsing outside with a hose to keep the bathroom stain-free.
Color longevity is a mixed bag — some owners mention it lasts over a month, while others wish it hung on longer. This 3-pack covers a few applications. It produces a beautiful, pure black that covers gray well, though don’t expect any blue shimmer in this “Oriental Black” shade.
The Trade-Off: You get gentle, believable black coverage that’s kinder to your hair and scalp, but you sacrifice the lifting power and sometimes the longevity of a traditional permanent dye.
7. Clairol Nice’n Easy 1BB Deepest Blue Black
The “raven’s wing” black — a deep, rich, natural-looking shade with 100% gray coverage.
This is for you if your goal is a deep, natural black with just a whisper of blue. The formula relies on 3 tones and highlights to enhance your hair’s natural highs and lows, so the result looks like it could be your natural color. It’s oil-infused to smooth the hair for better color uptake and comes with a Revitashine Intense Treatment.
Customers note a rich, shiny color that leaves hair looking healthy. One buyer describes it as giving a “raven’s wing hue” and notes it works better than salon treatments. Another, who started with naturally black hair, wishes the blue came out a bit more — a reminder that the blue shows best on lighter starting shades.
Worth noting: longevity is a mixed issue here. While some see it wash out within two months, others find the color “bleeds terribly” during washing. It’s a permanent formula with a complete kit — color cream, activator, treatment, gloves, and instructions — so it’s easy to use.
The Star Quality
- Deep, natural-looking black with a subtle blue hint
- Oil-infused formula for smooth application
- Comes with Revitashine treatment for strengthened hair
The Drawback
- Color can fade faster than some, showing within two months for some users
- Can bleed heavily for the first few washes
Best for: anyone after a sophisticated, true-to-nature black that offers impressive shine and complete gray coverage.
Consider the trade-off: if long-lasting color is your top priority, this may need more frequent touch-ups than you’d like.
8. Bigen 88 Blue Black Permanent Powder (3-Pack)
The brand-loyal favorite that fades naturally and never washes out to a purple or green.
This is the dye for those who’ve found their holy grail and stick with it for decades — literally. Many owners have used this Bigen shade for 20+ years, valuing its excellent gray coverage and the way it fades so naturally that nobody can tell you color your hair. It’s a deposit-only powder, which means it’s less damaging than permanent liquid dyes.
The blue-black shade is subtle, appearing as a pure black to most, but it’s excellent at covering brassy gold tones. It never washes out to a weird purple or green, instead fading gradually to a dark, natural reddish-brown. For root touch-ups every few weeks, it’s a reliable, gentle choice that leaves hair shiny and soft.
This dye is gentler on your natural hair because it only deposits color (it doesn’t lift or strip your existing shade). Plan your quantity: if your hair is shoulder-length and thick, you may need two boxes to cover it all. For a gentle, no-damage black with a cool undertone, this 3-pack delivers without the harshness of permanent dyes.
The Confidence Pick: If you want gray coverage that looks natural and stays that way, this deposit-only blue-black is your match. It never fades to an odd tone, and it holds through more washes than typical dyes—so you won’t need to reapply as often. Long-term users stick with it for that reliability.
9. Smart Beauty Blue Black Permanent Dye
A vegan, cruelty-free blue-black with a built-in plex treatment to protect hair structure.
For the ethically-minded dyer, this British brand offers a premium kit that blends a permanent dark blue-black with a plex hair treatment designed to protect, rebuild, and restore your hair’s structure. It’s vegan and cruelty-free, using UK and European-endorsed cosmetic standard ingredients. It works on all hair types, including chemically treated, Afro, and Asian hair.
The application is designed to be mess-free — you mix the color cream and developer in the provided bottle, then apply with a precision nozzle for a non-drip experience. Reviewers point out it leaves hair super soft with great gray coverage. The color tends to be black with a navy blue hue that reveals itself in the light, rather than an obvious blue-black.
Results vary here. Buyers praise the coverage and softness, but the color and staying power get mixed reviews—some say it fades fast, and a few report it looks “just plain black” rather than blue-black. The kit weighs 7.05 ounces and includes everything you need. It’s made by an independent British brand that focuses on ethical practices.
The Ethical Bonus
- Vegan and cruelty-free, with a plex treatment for hair health
- Mess-free, non-drip application with a precision nozzle
- Leaves hair feeling super soft with good gray coverage
The Variable
- Color results are unpredictable — some see a navy hue, others see plain black
- Longevity is inconsistent, with some reporting quick fading
Reach for it if: ethical, vegan credentials are a must and you want a kit with everything included for a non-drip application.
Look elsewhere if: you demand a predictable, long-lasting blue undertone, as results are more variable than the top picks here.
Understanding the Specs
Permanent vs. Demi-Permanent
A permanent dye like the Revlon or L’Oreal options uses a developer to open the hair cuticle and deposit color that lasts until it grows out. A demi-permanent formula like Clairol Natural Instincts is gentler, coating the hair without penetrating as deeply, so it fades more gradually over several weeks. Deposit-only powders from Bigen add color without any lifting, making them ideal for gray coverage or enriching natural color without changing your base shade.
Gray Coverage and Developer
“100% gray coverage” means the formula is designed to coat resistant gray hairs completely. Box dyes often include everything you need, while pro formulas like Schwarzkopf and AGE beautiful require a separate developer cream. Using the right developer volume matters — 10 volume is gentler for damaged hair, while 20 volume is standard for gray coverage. If you’re covering stubborn grays, look for a formula specifically claiming “100% gray coverage” to avoid patchy results.
