Choose Permanent Hair Dye for Grey Coverage and Shade Changes

Begin with a consultation covering the natural base, percentage and distribution of grey hair, previous colour and desired result. Grey coverage depends on the specific colour range, shade choice and technical method. Permanent hair dye can support lasting colour changes, but the appropriate formula and expected colour results vary with the starting hair. Do not assume a shade chart guarantees an identical finish on every hair type.

For a dark blonde, brown or red result, consider both the depth and tone of the existing base. Existing permanent colour can influence a subsequent service, so assess the lengths separately from new growth. A professional colourist should decide whether the target is achievable with permanent colour alone or whether a separate lightening step is needed.

Majirel, INOA, Koleston Perfect and Life Color Plus

Our range of permanent colour includes L'Oréal Professionnel Majirel and INOA, Wella Koleston Perfect and FarmaVita Life Color Plus. Compare the exact product listing, shade and compatible developer before ordering. INOA and other ammonia-free permanent hair colour systems have their own technical requirements; ammonia-free does not mean that all products are interchangeable or suitable for every client.

Choose professional hair colour products as a complete system. Product-specific guidance determines mixing ratios, processing time, grey coverage techniques and any stated levels of lift. Where a formula claims long-lasting colour, judge that claim alongside the manufacturer's conditions and recommended aftercare. No permanent hair colour range eliminates the need to assess hair history and condition.

Permanent Colour, Semi-Permanent Colour or Toner?

Permanent colours, demi-permanent glosses, direct semi-permanent dye and toner serve different purposes. The best choice depends on the desired commitment, tone and maintenance plan. A direct dye may not require developer, while oxidative colour systems need a specified activator. Review the exact instructions instead of treating every product described as semi-permanent alike. Explore our semi-permanent colour collection for other professional options.

Compatible Developer and Hair Bleach

Select the developer approved for the permanent hair colour and the intended service. A higher peroxide strength is not automatically the right option for grey coverage or deposit. For hair bleach, use only the compatible system and an approved technique. Check the required consultation and product-specific precautions before each chemical service.

Hair Care for Coloured Hair

Plan aftercare to suit the finished shade and the condition of the hair. A suitable shampoo, conditioner and treatment can support manageability and the appearance of coloured hair. Consider hair damage, previous lightening and heat styling when choosing the routine. Browse professional hair care alongside the colour range and explain the manufacturer's maintenance advice to the client.

Permanent Hair Colour FAQs

Does permanent hair colour always cover all grey hair?

Coverage depends on the particular formula, shade, grey percentage and technical method. Follow the colour range's grey coverage instructions and assess the expected result during consultation.

Can I use the same developer with every permanent dye?

No. Match the exact developer, concentration and mixing ratio to the manufacturer's approved colour system.
