Blue-black hair continues to be one of the most dramatic and eye-catching shades in alternative and everyday fashion. This colour blends the depth of pure black with flashes of blue, creating a vivid midnight effect that stands out in both natural and artificial light. Whether you want a subtle blue tint or an intense, inky finish, Beserk offers an extensive range of blue-black hair dye and colour options to help you achieve the exact tone you’re imagining.

For those searching for black blue hair dye permanent formulas, this collection includes long-lasting, highly pigmented products designed to deliver deep coverage and bold results. Permanent blue-black dyes are perfect if you want a rich dark shade that does not fade quickly and keeps its cool blue undertone for weeks. These formulas provide a glossy, dimensional effect that looks dramatic yet refined.

We also stock a wide selection of semi permanent hair dye blue black options, ideal for experimenting or refreshing your colour. Semi-permanent dyes coat the hair without lifting or damaging it, giving you the flexibility to deepen your natural shade, add a blue tint to dark hair, or create a softer midnight result. These shades gradually fade over time, making them perfect for creative styling, blending and transitioning between colours.

Blue tones have always been popular within goth, punk, cosplay and fantasy aesthetics, and blue-black hair remains a staple because it is bold yet versatile. These shades also pair well with mermaid, galaxy and gradient styles. Blue dye is available in countless tones, from pastel sky blue to vibrant cobalt and deep navy. Many customers mix multiple colours to customise their final shade, creating layered blue-black blends that are unique to them.

If you want to explore different combinations, our full hair dye range includes everything from vivid pigments to pastels. At Beserk, we celebrate individuality, and hair colour is one of the most powerful ways to express yourself.

Common Questions

What Is Blue-Black Hair Dye?

Blue-black hair dye combines deep black pigments with cool blue tones. This creates either a black shade with a blue sheen under light or a dark base with visible blue accents. The result is flattering on a wide range of skin tones and works for subtle or dramatic styling.

How Does Blue-Black Hair Dye Work?

Blue-black dye works by depositing colour molecules into the hair shaft. Some formulas lightly lift the natural colour before adding pigment, allowing the blue undertones to appear clearly. Choosing the right product for your hair type ensures an even, vibrant finish whether you use a permanent dye or a semi-permanent one.

How Long Does Blue-Black Hair Dye Last?

Most blue-black dyes last around 4 to 6 weeks. Permanent formulas generally last longer and maintain their intensity with proper aftercare. Semi-permanent dyes will fade more gently and can be refreshed easily with colour-depositing products.
