    Professional Hair Colour for UK Salons

    Discover professional hair colour for salon services at Mus & Co, including permanent hair dye, demi-permanent colour, semi-permanent shades, toners, bleach and compatible developers. Our collection brings together colour options for grey coverage, root regrowth, colour correction and creative work. Compare established salon brands and choose a formula suited to the client's starting shade, hair type and desired result. Professional stylists can explore everything from natural-looking tones to more expressive colour finishes.

    Permanent Hair Colour and Grey Coverage

    Permanent colour is a popular choice for long-lasting results, changing depth and covering grey hair. Salon ranges offer natural, warm, cool and fashion shades, but grey coverage and colour longevity depend on the formula, existing hair and correct processing. For an even, true-to-tone finish, follow the individual colour brand's instructions for mixing, timing and suitable developer. Colour services should consider regrowth, previous treatments and hair health rather than relying on a shade chart alone.

    Explore our permanent colour collection for professional dye options.

    Demi-Permanent, Semi-Permanent and Gloss Colour

    Demi-permanent hair colour is often selected to refresh tone, soften the appearance of regrowth or add a colour gloss without the same level of permanent change. Semi-permanent formulas offer another approach to toning and colour experimentation. These categories are not interchangeable: processing, lift and results vary by product. A toner or acidic gloss can be useful when adjusting the appearance of lightened hair, subject to the manufacturer's technical guidance.

    Clients with coloured hair may be concerned about colour fade and vibrancy. Choosing suitable aftercare and limiting unnecessary stress on damaged hair can support the look and feel of the finish. Browse our semi-permanent colour range for available options.

    L'Oréal Professionnel: Majirel, INOA and Dia Light

    L'Oréal Professionnel offers salon colour solutions across several services. Explore Majirel for permanent colour, INOA for ammonia-free colour options and Dia Light for selected tone-on-tone and gloss services. Check whether the specific range requires its dedicated activator or developer; mixing ratios and timings are not universal. Shop L'Oréal Professionnel.

    Wella Professional: Koleston Perfect and Color Touch

    Wella Professional ranges include Koleston Perfect for permanent hair colour and Color Touch for demi-permanent colouring. Illumina Colour and Welloxon developer options are also available. Select the correct shade, developer and technique for each service and consult the product's technical instructions. Explore Wella Professional.

    Schwarzkopf Professional: IGORA ROYAL and BLONDME

    Schwarzkopf Professional IGORA ROYAL provides permanent colour options, while BLONDME products support selected lightening services. A colourist planning blonde results, balayage or a tone adjustment should assess the starting hair condition and use compatible professional products. Discover Schwarzkopf Professional.

    Developers, Bleach and Colour Aftercare

    A suitable developer is as important as the chosen hair colour. Not every developer works with every professional colour range. Follow the manufacturer's recommended strength, proportions and processing time instead of substituting products. When lightening is required, browse professional bleach and lighteners and compatible developers designed for the intended salon service.

    Hair care continues after the appointment. A suitable shampoo and conditioner for coloured hair can help maintain softness and reduce the appearance of colour fade. Depending on the hair's condition, nourishing treatments may also support the feel of healthier hair. Always check the individual product guidance, especially for sensitive scalps.

    Choosing the Right Professional Hair Dye

    The best professional hair colour brands for your salon will depend on the services offered, shade range, client needs and familiarity with the technical system. Consider permanent versus demi-permanent colour, grey coverage, ammonia preferences, hair texture and desired tone. Avoid assuming that a formula is cruelty-free, ammonia-free or suitable for every hair type unless the product information confirms it.

    Frequently Asked Questions

    What is the difference between permanent and demi-permanent hair colour?

    Permanent colour is generally chosen for a longer-lasting change and, depending on the formula, stronger grey coverage. Demi-permanent formulas are more commonly used to refresh tone or enhance shine. Always compare the specific product's capabilities and instructions.

    Can I use any developer with professional hair dye?

    No. Use the developer approved for the exact colour system. Strength, mixing ratios and processing times vary, and using an incompatible product can affect colour results.

    How can I help maintain salon hair colour?

    Choose an appropriate shampoo and conditioner, follow aftercare guidance and select products suited to the client's hair type. The rate of colour fade varies according to the formula, hair condition and care routine.

    Is an allergy alert test necessary?

    Follow the manufacturer's allergy alert test directions before using oxidative hair colour. Some ranges require a test 48 hours before use, even when the client has coloured their hair before.
