Blue Hair Colour & Dyes

Blue is bold and electric, and it is also one of the trickiest colours to get right. The right shade makes a statement, while the wrong one can look muddy or fade into something you never planned for, and unlike natural colours, blue does not grow out subtly. It asks for commitment, careful application, and the right products to keep it vibrant. This collection brings together professional semi-permanent blue dyes in a spectrum of shades, from pastel periwinkle through to deep navy.

The AMR Blue Range

Whether you are after an electric aquamarine, a soft powder blue, or a deep indigo, this collection has a shade to suit. All the blue dyes here are semi-permanent, so they deposit colour onto the hair's surface and fade gradually, with no developer, ammonia, or mixing required.

• Adore. Twelve shades in 118ml bottles, ammonia-free direct dyes that apply straight from the tube. The range runs from Powder Blue, Baby Blue, and Sky Blue at the soft end, through Aquamarine, Periwinkle, and Ocean Blue in the middle, to Sapphire Blue, Luxe Blue, Indigo Blue, and Royal Navy at the deep end, while Emerald and Jade sit on the blue-green line, closer to teal than true blue.

• Matrix SoColor Cult Semi. Admiral Navy and Retro Blue, both in 118ml, are professional-grade formulas that last up to 20 washes when used and cared for properly.

• Pravana Pastels Blissful Blue. A soft pastel blue in 90ml, from the ChromaSilk Vivids range.

Semi-Permanent vs Permanent Blue

Semi-permanent colour deposits pigment without lightening the natural base, which is what makes it gentler than permanent colour and easier to move away from, and it also means the result depends entirely on where you start.

On light or pre-lightened hair, blue appears vibrant and close to the tube, while on darker hair it shows as a tint that is most visible in sunlight. Because blue cannot lighten dark hair, a vivid result requires lifting the base first. You can expect the colour to fade over roughly four to eight weeks, depending on how often you wash and the condition of your hair.

How To Make Blue Hair Last

First, wash with cool water. Heat opens the cuticle and releases colour. Cool water keeps the cuticle sealed and locks pigment in. Next, use colour-safe shampoo. Regular shampoos strip semi-permanent colour faster. Sulphate-free options are gentler and help blue last longer.

Wash less often. Over-washing fades blue faster. Extend time between washes with dry shampoo. Aim for two to three times a week. After washing, apply a colour conditioner. Refresh your blue between applications with a blue pigmented conditioner. It adds pigment and moisture simultaneously. And don’t forget to protect from heat. Heat styling accelerates fading. Use a heat protectant and keep temperatures moderate.

Preparing the Hair

If you are starting from dark hair, the base needs lifting before any blue will show, so use hair bleach with the right peroxides and developers to reach the level your shade needs, then follow with a hair toner to take out any remaining yellow. Warmth left in the base is what pulls blue towards green.

Pastels ask the most of the base, and Powder Blue, Baby Blue, Sky Blue, and Blissful Blue all want hair lifted to a pale yellow or lighter. The deeper shades carry more pigment, so Royal Navy, Admiral Navy, Indigo Blue, and Sapphire Blue can sit over a darker base and still read blue.

How To Make Blue Hair Last

Blue fades faster than natural shades, and it fades visibly, because there is no dark base underneath to hide behind.

• Wash with cool water. Heat opens the cuticle and lets pigment escape, while cool water keeps it sealed.

• Wash less often. Two to three times a week is enough, and you can stretch the gaps with dry shampoo.

• Use colour-safe cleansing. Regular shampoos strip semi-permanent colour quickly, so reach for colour shampoo or sulphate free shampoo instead.

• Refresh with pigment. A colour conditioner tops up the tone and adds moisture between applications.

• Keep the heat down. Hot tools speed up fading, so use a heat protectant and keep temperatures moderate.

• Watch the pool and the sea. Chlorine and salt water both pull blue out fast, and chlorine can push it green.
  

Why Salon-Grade Blue Makes the Difference

Professional blue uses higher-quality pigments that deposit more evenly and fade more gracefully than drugstore alternatives. The colour is more vibrant initially and fades to a softer tone rather than a muddy or greenish tint. Professional formulas are also less drying, so your hair stays healthier through multiple applications.

AMR stocks salon-quality blue hair colour from Adore, Matrix, and Pravana, alongside the hair colouring tools to apply it. Shop at an AMR store near you, or have your order delivered anywhere in Australia. The wider hair colour range includes purple hair dye and green hair dye, both of which mix well with the blues here.

Beyond colour, you will find shampoos, hair conditioners, and hair treatments to keep your blue vibrant, plus bulk hair care products for salons that regularly work with fashion shades.
