How to find the best blue hair dye for dark hair

Dyeing your hair blue is certainly fun, but you need to keep in mind that your hair is a sensitive thing that can get damaged easily, which is why you shouldn’t just choose the most vibrant and longest-lasting hair dye, but also make sure that it’s a high quality, safe, and gentle formula that won’t cause hair damage.

Type of hair dye

Hair dyes come in many different types. Here’s a list of the most common ones and how they differ from one another:

Permanent

As the name suggests, a permanent hair dye is the longest lasting type of hair dye that permanently transforms your hair color with the use of a developer that opens up hair cuticles to let the hair dye deeply penetrate the shaft, before finally resealing the cuticles to prevent the dye from washing off.

A permanent hair color lasts indefinitely and won’t fade over time, since it alters the natural structure of your hair color. The downside with this is if your natural and colored hair has a stark difference, it will become obvious as your hair grows longer.

Demi-permanent

A demi-permanent hair dye also makes use of developer, but with a lower volume. It also typically contains ammonia. This is a sheer formulation that partially opens hair cuticles to let the dye penetrate your strands and darken your hair color or change its tone while adding shine.

This type of dye doesn’t really lift hair color nor cover gray strands, which only works with permanent hair dyes. It also gradually fades after 12 to 24 washes.

Semi-permanent

Meanwhile, semi-permanent hair color is a gentler formulation that is ammonia-free and doesn’t require the use of a developer, since it only deposits the hair dye over the hair surface to alter the hair tone, thus giving you a subtler sheer coating.

Since it doesn’t penetrate the hair cuticles, it also cannot lighten your hair color nor cover grays. It also only lasts for about 4 to 12 shampoos before it starts fading.

Temporary

If you just want a fun hair color for a specific event, or just to have a bit of fun for the day, a temporary hair color is the way to go, since it gives your hair a vibrant color that you can easily wash off the next day.

Ammonia-free

As you have seen above, some types of hair dyes come with ammonia, which is damaging to the hair, so you’ll need a lot more hair care and maintenance if you go with those options. But, if you want a safer and more natural alternative, there are also lots of ammonia-free formulations on the market that can give you wonderful looking hair that’s still healthy after coloring.

Non-drip formula

Some hair dyes are very liquid and runny, which means they are difficult to apply, and you’ll get a lot of dye on your neck, face, and clothes. To prevent this from happening, go for a non-drip formula that is easier and less messy to apply and rinse.

Conditioner

Ideally, your hair dye should come with a conditioner to protect your hair from damage and dryness. It can either be in a separate packet but in the same box, or blended with the hair dye. Either way, it should contain key ingredients that moisturize, nourish, and protect your hair, such as coconut oil, shea oil, avocado oil, and olive oil.

Current hair color

Again, if your natural hair color is a dark shade of brown or black, go for a lighter hair dye, since dark plus dark means darker, but light plus dark gives you a more accurate color. Meaning, if you have light or blonde hair, you can apply a dark shade directly and get the result you want.

If you want your hair to be low maintenance, go for a hair dye that’s at most one or two shades lighter or darker than your natural hair color. It will make the resulting color look natural while making things easy to maintain.

Skin tone

If you want to look vibrant rather than pale and sickly, choose a hair color that matches your complexion. If your skin tone is cool, go for cool hues, or if it’s warm, golden, or olive, go for warmer shades.

Face shape

It’s also important that your new hair color frames your face well, meaning, you need to take your face shape into account. If your face is narrow and you want it to look fuller, go for a blend of dark and light, with the darker shade on top and the lighter shade along the sides.

On the other hand, if your face is more rounded or wider, the darker shade should be along the sides while the lighter shade should go on top to elongate your face.

Natural hair texture

Even your natural hair texture matters. If you have smooth hair, fortunately, everything can work for you, but if you have porous hair, for example, blonde and pastel colors won’t be suitable. Or, if your hair is coarse, darker shades will give the appearance of healthy and moisturized strands, whereas a lighter shade will reflect too much light and dry out your hair.

Harmful ingredients you need to avoid

Many hair dyes, especially permanent ones, come with lots of strong and harmful chemicals that can really damage your hair.

Ammonia, for one thing, can irritate your respiratory system and cause asthma, or even disrupt your endocrine system. P-phenylenediamine can irritate your skin, cause allergies, increase toxicity levels in your blood and liver, and cause birth defects. Then there’s hydrogen peroxide, which can irritate your skin, eyes, and lungs.

You might also find neurotoxin in the ingredients list, which can cause allergies, birth defects, and pregnancy loss, or resorcinol, which can disrupt your endocrine.

Best blue hair ideas for dark hair

Not sure how to rock blue hair? Here are some ideas you can try:

Black to blue ombre

Feeling lazy to color your bum length hair? You can just do the bottom half and still look like a bombshell with a sleek and stunning black to blue ombre. The blue at the bottom wonderfully complements your natural black hair, plus it saves you on hair dye too.

Denim colored hair

Feeling adventurous but not quite? How about you take out your favorite denim jeans and go matchy-matchy with the perfect hair color? There’s no one shade of blue to choose from, many options work great as long as you create dimension and achieve that lightly washed effect.

Dark navy blue

If you want a more “classic” blue look that’s definitely blue, but with dark undertones, a dark navy blue color will look vivid and especially amazing under the sunlight, since the rays magnificently bounce off the blue.

Subtle blue streaks

If you want just a tiny hint of blue to complement your otherwise jet black hair, adding subtle blue streaks on the bottom half of your strands will work stunningly great. It’s not distracting nor attention seeking; it’s just a lovely shade that shows itself when your hair catches the light a certain way.

Final tips

As you have seen, there are plenty of amazing options when it comes to blue dyes for dark hair, so you just need to be careful in what you buy, and take into account important factors, so you can get the best possible dye that makes you look great while keeping your hair healthy.
