What You'll Learn

Choosing the right shade of blue dye
When choosing the right shade of blue hair dye, it's important to consider your starting hair colour, as this will affect the final result. If you have dark brown hair, you may want to opt for a darker shade of blue, such as midnight blue or a blue-black shade, which will give your hair a deep, intense colour with hints of blue. These shades are known to be more forgiving on dark hair and can create a stylish look, especially when paired with a bold brow and black eyeliner.
However, if you're looking for a brighter, more electric shade of blue, it's crucial to lighten your brown hair first. Bleaching your hair will provide a blank canvas for the blue dye to truly shine and prevent unwanted green tones, which can occur when dyeing brown hair blue. This step is essential if you're aiming for a bold, vibrant shade.
Once you've decided on the desired shade, it's worth noting that not all blue dyes are created equal. Some brands and specific shades are known to be more pigmented and long-lasting than others. For instance, Manic Panic Midnight Blue and Pravana Vivids in Blue are popular choices, with the latter being highly pigmented and longer-lasting.
If you're looking for a temporary option or want to test out different shades, semi-permanent dyes like those from Manic Panic or Special Effects brand in Blue Velvet offer a fun, low-commitment way to experiment with blue hair. These dyes typically last a few weeks and gradually fade, making them perfect for those who like to change their hair colour frequently.
Finally, when choosing a shade, consider your skin tone and the overall look you want to achieve. Some shades of blue, like teal and turquoise, complement all skin tones and can be styled in various ways, from a single aqua tone to a mix of different blue shades. If you have a fair complexion, a gentle sky blue shade can be a beautiful choice, especially when paired with peachy blushes and shimmering makeup.

Bleach hair before dyeing
If you want to dye your hair a lighter colour than its current shade, you will need to bleach it first. Bleach removes the previous colour from your hair follicles, lightening the hair and allowing the new colour to be applied on top. However, bleaching can be damaging to hair, so it is important to take steps to minimise this damage. Before bleaching, assess the condition and health of your hair. If your hair has been coloured or bleached several times in the past year to 18 months, it is best to wait until your hair has healed. Similarly, if your hair is frizzy, dry, or prone to breakage, it is recommended to leave the bleaching to a professional colourist.
If you decide to proceed with bleaching your hair, there are a few steps you can take to reduce the damage to your hair. Firstly, use a deep conditioner on your hair before bleaching it. This will help to build up moisture in your hair, which may be damaged during the bleaching process. There are many different types of deep conditioners available, from store-bought options to natural, DIY alternatives made from foods such as bananas, avocados, mayonnaise, yoghurt, eggs, and coconut oil.
After bleaching, you can use a protein filler to fill in gaps in your hair so that the colour will go on more evenly. You can add a small amount of protein filler directly to your hair before applying the dye, or you can mix a very small amount into your hair dye (be careful not to add too much, as this will make the dye too runny).
Once you have bleached your hair, you can decide which colour you want to dye it. Keep in mind that bleached hair can turn out to be an unnatural shade of blonde, so you may want to use a toner to offset these tones. Toner comes in a variety of colours, including purple, blue, and green, and can be purchased from beauty supply stores, salons, or online. You can apply the toner immediately after bleaching, or wait a couple of days to see which colour of toner is needed.

Avoid green undertones
To achieve a vibrant electric blue colour on brown hair, it is important to take into account the potential for green undertones to emerge during the dyeing process. Here are some tips to avoid those unwanted green hues:
Firstly, it is recommended to steer clear of temporary vegetable dyes as they may not adequately cover dark brown hair, potentially resulting in greenish undertones. Instead, opt for a permanent or demi-permanent dye that is specifically formulated to counteract unwanted green tones. These dyes contain warmer pigments that can help neutralise the cool tones in brown hair, preventing an undesirable greenish cast.
Bleaching is another crucial step to consider. Bleaching the hair before applying the blue dye can significantly reduce the likelihood of green undertones. This is because brown hair has a mix of warm and cool tones, and bleaching removes these underlying pigments, creating a blank canvas for the blue dye. However, it is important to exercise caution when bleaching to avoid hair damage.
When selecting a blue dye, choose a shade with purple or red undertones, such as indigo or a purple-based blue. These shades are less likely to turn green as they already have a hint of green in their composition. Special Effects Blue Velvet is a popular option that users have reported does not turn green, thanks to its purple undertones.
Additionally, conducting a strand test before committing to a full head of hair is advisable. Apply the blue dye to a small section of hair, preferably on the underside, to see how the colour develops. This allows for any necessary adjustments to be made without affecting all of your hair.
Finally, if you are transitioning from bleached hair to blue, be aware that applying a brown overtone dye directly may result in blue or green hair. To avoid this, first fill your hair with a warm pigment such as orange or red, ensuring it is at least a light orange shade before applying the desired brown colour.

How to apply the dye
To achieve a vibrant electric blue shade, it is recommended that you start with very light blonde hair. If this is not your natural hair colour, you may need to pre-lighten your hair. You can then apply the dye straight from the tube, or mix a pea-sized amount with conditioner to create a unique shade. If you have thick hair or hair longer than shoulder-length, you may need two or more packs for even coverage.
Before dyeing, always perform an Allergy Alert Test 48 hours before colouring, even if you have used the product before. Use a clarifying or deep cleanse shampoo 48 hours before application and check the application range to ensure your natural hair is suitable for the dye.
To avoid staining your skin, apply a skin barrier cream around your hairline and ears. It is also recommended to have some cotton pads and skin toner on hand in case you get some product on your skin. An old towel can also help to avoid staining your clothes.
After applying the dye, follow the instructions on the packet for how long to leave it on for. You may need to reapply the dye regularly, as blue dye can fade quickly, especially on brown hair.

How to maintain the colour
To maintain electric blue hair colour, it is important to first get the base colour right. Blue hair dye over brown hair can often turn green, so it is recommended to lighten the hair before dyeing it blue. A professional colourist can help you achieve the right base colour and prevent over-bleaching.
Once you have the right base colour, you can apply the blue hair dye. To maintain the colour, use a toner and colour-safe shampoo. You can also use a colour-depositing conditioner—celebrity colourist Kiyah recommends the Davines Alchemic and evo Fabuloso lines. To prevent damage and dryness, get a professional conditioning treatment a few times a year and a trim every few months to prevent split ends. Kiyah also suggests using a deep conditioning and moisturising conditioner or hair mask every week.
To avoid staining, make sure your hair is completely dry before going to bed or sleeping on towels or pillows. The colour transfer will lessen over time, but it is important to be cautious, especially when the hair is wet.
To prevent the blue hair from turning green, use a blonde toner with purple undertones. This will neutralise any yellow or orange tones in the hair, keeping the blue colour vibrant.
Finally, be prepared to touch up the colour regularly, as blue hair dye can fade quickly. You may need to go for touch-ups every two months or so to maintain the colour.
