Can I dye my black hair blue at home?

Dying black hair to blue at home is quite simple. There is a wide array of blue-black hair dyes available in stores that can give your hair that desired color.

The outcome of the color depends on your current hair shade.

  • If your hair is light to dark brown or black, achieving an all-over blue-black color can be easily done by yourself when it comes to a darker shade. However, if you desire a more dramatic transformation, you will need to lighten your hair with bleach.
  • If your hair is blonde or lighter, you already have a suitable base for achieving a vibrant blue-black hue. If you look for pastel blue tones or highlights, you need to lighten your hair with bleach. Unsure? It is always best to consult with a hairdresser for guidance.

What happens if you dye black hair blue?

If you dye black hair blue, the outcome will depend on the specific hair dye used and the condition of your hair. Here are some possible scenarios:

  • Subtle Blue Tint: If you use a semi-permanent or temporary blue hair dye on black hair, you may achieve a subtle blue tint or sheen that is visible under certain lighting conditions. The blue may not be noticeable unless you are in direct light or sunlight.
  • Blue Undertones: Some blue hair dyes are formulated to work on dark hair without bleach. In this case, the dye adds blue undertones to your black hair for a hint of blue in certain lighting. The effect will be more prominent on lighter sections of your hair or when light hits it directly.
  • Dark Blue Hue: If you use a permanent or long-lasting blue hair dye on black hair without bleaching, the result may be a deep, dark blue hue. The shade will be most apparent under bright light or sunlight, but it is not be as vibrant as it would be on lighter hair.
  • Pre-Lightening Required: To achieve a vivid and vibrant blue color on black hair, pre-lightening or bleaching is usually necessary. Bleaching helps remove the natural pigment from the hair, allowing the blue dye to show up more prominently. Without pre-lightening, the blue dye will not be visible or may appear as a faint tint.

How to color black hair with blue

How to dye black hair to blue with bleach

When you use bleach to dye black hair blue, the bleach helps to lighten the natural pigments in your hair. This lightening process allows the blue dye to show up more prominently for a brighter and more vibrant blue color. Bleaching is necessary when you want a vivid and eye-catching blue shade on black hair.

  • Bleaching: The first step involves applying bleach to lighten the natural pigment in black hair. Bleach helps to remove or lift the dark color to create a blank canvas for the blue dye to work on.
  • Lightening process: The bleach is left on the hair for a specific amount of time, depending on the desired level of lightness. It is crucial to monitor the hair closely during this process to avoid over-processing or damage.
  • Rinse and shampoo: After achieving the desired level of lightness, the hair is rinsed thoroughly to remove residual bleach. A gentle shampoo helps cleanse the hair and scalp.
  • Blue dye application: Once the hair is dry, a blue hair dye is applied. The dye adheres to the lightened hair strands for a vibrant blue color.
  • Processing and maintenance: The blue dye is left on the hair for the recommended processing time specified by the manufacturer. To maintain the color, it is important to use color-safe hair care products and avoid excessive heat styling or prolonged sun exposure.

How to dye black hair to blue without bleach

Dyeing black hair to blue without bleach means working with the existing dark pigments in your hair and adding a blue tint or undertone. This method results in a more subtle and subdued blue color, often seen as a dark blue or blue-black shade. It is a suitable option if you prefer a more natural-looking blue hue or want to avoid the potential damage caused by bleach.

  • Selecting a dark blue hair dye: Instead of using bleach, choose a dark blue hair dye formulated for unbleached hair. These dyes are designed to work with the existing dark pigments in black hair to create a more subtle blue tint or undertone.
  • Hair preparation: Clean, dry hair is preferred for this process. It is important to avoid using any products that interfere with the dye’s absorption.
  • Blue dye application: The dark blue hair dye is evenly applied to the hair, starting from the roots and working through to the ends. The dye is left on for a specific processing time, as directed by the manufacturer.
  • Rinse and condition: Once the processing time is complete, the hair is rinsed thoroughly with cool water until the water runs clear. Use a color-safe conditioner to moisturize and maintain the color.
  • Maintenance: To keep the blue color vibrant, you should use color-safe and sulfate-free hair care products. Additionally, using color-depositing conditioners or hair masks specifically formulated for blue hair can help refresh the color between dyeing sessions.

Dos and don’ts of dying black hair to blue

Dos

– Carefully choose your hair dye. Not all blue shades will show up on dark hair, so select a dye specifically formulated for your natural hair color. In addition, read the instructions on the dye container to ensure compatibility.

– Be mindful of the color intensity. Dark hair may not achieve pastel shades, so opt for darker blue hues that will show up on your hair.

– Choose your dye wisely. While some inexpensive dyes can be effective, consider the quality of the ingredients to ensure a better outcome.

Don’ts

– Avoid excessive heat styling. After dyeing your hair blue or any other color, minimize the use of blow dryers, straighteners, and curling irons. Heat can cause color fading and degradation.

– Refrain from shampooing immediately after dyeing. Give your hair at least 48 hours before shampooing to allow the color to set and last longer.

FAQs about dying black hair to blue

What hair color is suitable for dyeing it blue?

Blue hair dye can be applied to various hair colors, including black hair. However, achieving vibrant blue requires lightening the hair with bleach before applying the blue dye. Lightening allows the blue pigment to appear more prominently. On unbleached black hair, the blue color will appear as a darker blue or blue-black tint.

How can I prevent my hair from turning green when dyeing it blue?

To avoid undesired green tones when dyeing hair blue, it is important to consider the hair’s undertones and choose the appropriate shade of blue dye. If your hair has warm undertones, it is more prone to turning green when exposed to blue pigments. To prevent this, opt for blue dyes with cool or neutral undertones, such as navy blue or royal blue. Additionally, avoid mixing blue dye with yellow-based or green-based toners to minimize the risk of green discoloration.

How long does blue hair color typically last?

The duration of blue hair color varies depending on factors such as the dye’s quality, hair porosity, and maintenance routine. Generally, vibrant blue shades tend to fade more quickly compared to darker blue or blue-black shades. With proper care and the use of color-safe products, blue hair color can last anywhere from a few weeks to a couple of months. Regular touch-ups and color-refreshing treatments may be necessary to maintain the desired blue hue.

Does dyeing black hair cause damage?

Dyeing black hair, especially when bleaching is involved, can cause damage to the hair. Bleaching can strip the hair of its natural moisture and weaken its structure. To minimize damage, it is important to follow proper hair care practices, like using high-quality hair dyes, incorporating deep conditioning treatments, and minimizing heat styling. Regularly moisturizing and nourishing the hair can help mitigate the effects of dyeing and maintain healthy hair.
