How to Dye Black Hair Blue The Right Way

Disclaimer: This content is for informational purposes only and does not constitute professional treatment. Always perform a patch test and strand test before applying bleach or hair dye.

So you have black hair and are ready to venture into the realm of vibrant colors, specifically midnight blue? Achieving this mesmerizing shade can be done in two primary ways.

One way is by using a temporary dye designed for dark hair. This method is simpler and less damaging to your hair, but the color will only last between one and twelve washes.

The other option is to bleach your hair and then apply a blue semi-permanent dye, which will yield a more permanent result but requires more care and preparation.

To achieve a deep midnight blue, you only need to lighten black hair to a light brown or dark orange stage. Lightening all the way to blonde is only needed for pastel or bright blues.

Although this process can be safely handled by a professional stylist, if you’re adventurous and prefer a DIY approach, it’s important to arm yourself with the right knowledge and tools.

Method 1: Temporary Dye for Black Hair

Tools Needed

Before you embark on your at-home coloring adventure, you’ll need to gather a few essential tools:

  1. Clips to Hold Hair
  2. Blue Hair Dye
  3. Petroleum Jelly
  4. Gloves
  5. Hair dyeing brush and mixing bowl

The dye could be a chalk, wax, cream, or spray. Remember, this is a temporary method, so feel free to experiment with the type of dye that works best for you and your hair. Always wear an old shirt during application and use dark pillowcases, as temporary colors can transfer easily.

The Dyeing Process

Brands like Manic Panic and Color Brilliance are popular choices for at-home hair coloring. They offer a variety of colors, ranging from pastels to deep purples to vibrant blues.

Always remember to follow the manufacturer’s instructions when using these products.

Begin by sectioning your hair into four parts and securing each section with a clip. Make sure your hair is completely dry before starting the dyeing process.

Next, apply petroleum jelly around your hairline to prevent the dye from staining your skin.

Keep all hair dye and bleach strictly away from your eyes, and never use these products to color your eyebrows or eyelashes as it can cause severe injury or blindness.

Remove the clip from one section of your hair and start applying the blue dye. It’s best to part your hair one line at a time, using the hair dye brush to apply the color from root to tip.

Repeat this process until all sections are covered. If any dye gets on your skin or bathroom surfaces, wipe it off immediately. Always line your sink and floors with old towels or trash bags, as blue dye permanently stains porcelain and grout.

Remember, the manufacturer’s instructions will vary based on the product type. Always follow their guidelines for the best results.

Temporary dyes are usually safe to use at home, even on damaged hair. They allow you to experiment with different colors without long-term commitment or substantial hair damage.

Method 2: Bleaching and Semi-Permanent Blue Dye

This method gives a more vibrant color and lasts longer but involves a harsher process due to bleaching. If your black hair color isn’t natural, use a formulated artificial hair color remover to shrink the dye molecules, as baking soda is damaging and ineffective. But if it’s natural then bleaching is the only option.

Preparing for Bleaching

Before bleaching, it’s important to assess the health of your hair. If your hair is already damaged, bleaching might further harm it. Therefore, consider getting a professional consultation before you proceed.

You should also understand that bleach can be quite damaging to hair. It’s advisable to condition your hair and avoid heat styling for at least a week before you plan to bleach it.

Bleaching Process

If you decide to proceed with bleaching, be sure to follow the product’s instructions carefully. It’s important to use gloves during this process to protect your hands. Always perform a 48-hour skin patch test before using bleach or hair dye to check for dangerous allergic reactions.

Start by dividing your hair into sections. Apply the bleach from the mid-lengths to the ends, avoiding the roots. Once the mid-lengths and ends have lightened to the desired shade, apply the bleach to the roots.

Rinse your hair thoroughly, then use a deeply hydrating moisture mask. Avoid heavy protein treatments immediately after bleaching, as they can make the hair rigid and prone to breakage.

Remember, bleach can cause your hair to become dry and brittle, so you should treat your hair with care after this process.

Applying Semi-Permanent Blue Dye

After bleaching, you can apply a semi-permanent blue dye to your hair. Section your hair and apply the dye from root to tip, ensuring full coverage. Wait for the recommended time, then rinse your hair thoroughly.

Using a color-protecting shampoo and conditioner will help maintain the vibrancy of the blue and prolong the color’s longevity.

Coloring your hair is a fun way to express your personality. With proper care and the right tools, you can successfully dye your black hair to a stunning midnight blue shade at home. Take your time, follow the instructions carefully, and always prioritize the health of your hair.
