What Is L’Oréal DIA Colour and Why Stylists Love It

Salon colour has evolved.

Clients are demanding glossy, natural-looking hair without damage or discomfort. This is exactly why many UK stylists are choosing L’Oréal DIA Colour as their go-to system for tone enhancement, shine revival, and gentle grey blending.

DIA Colour sits perfectly between semi-permanent and permanent colour. It offers richer results than traditional toners while avoiding harsh lift, strong odours, and obvious regrowth lines.

It is the ideal choice for clients who want a beautiful colour that puts hair health first.

What Makes DIA Colour Different?

L’Oréal DIA Colour uses an advanced, ammonia-free formulation designed to enhance tone while actively improving hair condition through every appointment.

• Melanin Gap Filler Technology restores missing pigment inside the fibre
• Acidic pH seals the cuticle for better shine and longer lasting tone
• Ionène G Complex strengthens and softens during development

This combination allows stylists to work confidently on all hair types, including those needing extra care.

The Results Speak for Themselves

Clients see and feel the difference immediately:

• Even tone that can last up to six weeks
• Noticeably smoother, silkier hair
• Soft fade that maintains a natural look
• Three times more shine than untreated hair

Stylists love its reliability. Whether you are glossing blondes, correcting warmth, or adding richness to dark bases, results are consistent and beautifully glossy every time.

• Suitable for first-time colour clients
• Ideal as a refresh between major appointments
• Versatile for glossing, grey blending, or tone correction
• Creates healthier-looking hair with every application

DIA Colour empowers professionals to deliver premium results quickly, helping salons boost loyalty and revenue without increasing appointment time.

Modern colour should look and feel luxurious. DIA Colour makes that easy.

Is DIA Colour permanent?
No. It is a demi-permanent colour system designed to fade softly without harsh regrowth.

Does it cover grey hair?
It blends up to 70 per cent greys for a subtle, natural finish.

Is it suitable for damaged or sensitised hair?
Yes. The acidic pH helps protect the cuticle and maintain hair health.

Will the colour fade evenly?
Yes. It is formulated for soft, controlled fading between refresh appointments.

Is DIA Colour comfortable for sensitive scalps?
Yes. The ammonia-free, low-odour technology makes the experience much gentler.

How often should clients return for maintenance?
A gloss refresh every 6–8 weeks keeps shine and tone beautifully consistent.
