Unleash the Power of Gentle Professional Colouring

  • **Optimal pH for Gentle Colour:** Expertly formulated for L'Oréal Professionnel's ammonia-free Dia Light and Dia Richesse tone-on-tone hair colours, ensuring a mild and respectful colouring process for the hair fibre. This demi-permanent oxidant ensures maximum comfort for clients.
  • **Consistent & Vibrant Results:** Guarantees uniform, luminous, and long-lasting colour deposit, providing exceptional vibrancy and true-to-tone results with every application. Achieve salon-quality perfection in every shade.
  • **Superior Hair Conditioning & Shine:** Enriched with nourishing ingredients, this developer helps to maintain the hair's integrity, leaving it feeling soft, looking healthy, and boasting an incredible, salon-quality shine. It's more than just a developer; it's a hair conditioner booster.
  • **Versatile Colouring Solution:** Ideal for a wide array of services including refreshing faded colour, adding a high-gloss finish, subtly blending first greys, or achieving delicate colour changes without lifting the natural base. Perfect for a gloss hair treatment or a subtle colour refresh.

Understanding the 9 Vol (2.7%) Advantage for Hair Professionals

The L'Oréal Professional Dia Activateur Developer in 9 Vol (2.7%) is precisely calibrated for specific colouring outcomes, making it an indispensable tool in any professional salon. Unlike higher volume developers that lift natural hair colour, the 9 Vol (2.7%) oxidant is designed for:

  • **Gentle Deposit Only:** It provides sufficient power to open the hair cuticle just enough for colour pigments to deposit effectively, without causing any noticeable lift to the natural hair base. This is crucial for maintaining hair health and avoiding unwanted brassiness, acting as a gentle hair dye activator.
  • **Tone-on-Tone Expertise:** Perfectly suited for demi-permanent and semi-permanent hair colour applications where the goal is to enhance, deepen, or change the tone of existing hair colour without altering its depth. It's the ideal hair developer for non-permanent solutions.
  • **Ammonia-Free Compatibility:** Its pH balance is optimized for L'Oréal Professionnel's ammonia-free Dia Light and Dia Richesse formulas, ensuring maximum colour performance and comfort for the client. This developer for ammonia-free colour is a top choice for sensitive scalps.
  • **Gloss & Refresh Services:** The lower volume makes it the ideal choice for creating stunning gloss treatments, refreshing dull ends, or providing a subtle colour boost between full colour appointments. It’s perfect for achieving that coveted 'healthy hair glow' and vibrant colour refresh.

The Perfect Partner for L'Oréal Professionnel Dia Light & Dia Richesse

This L'Oréal Dia Activateur Developer 9 Vol 2.7% is the official and recommended developer for the renowned L'Oréal Professionnel Dia Light and Dia Richesse hair colour lines. Each line offers unique benefits:

  • **Dia Light:** An acidic gel-cream tone-on-tone colour ideal for sensitised, coloured, or permed hair. It provides incredible shine, refreshes previously coloured hair, and neutralises unwanted tones without lightening the base. When mixed with Dia Activateur, it helps to perfect your colour work, offering a mirror-like shine and healthy-looking finish, making it a staple for hair lightener alternative services where deposit is key.
  • **Dia Richesse:** An alkaline tone-on-tone colour that is perfect for natural hair. It offers rich, deep reflects, covers up to 70% of first greys, and provides exceptional softness. The Dia Activateur ensures optimal colour uptake and longevity for these vibrant, ammonia-free shades, ideal for grey hair blending services.

Together, they form a powerful duo that respects the hair's condition while delivering professional, long-lasting, and intensely shiny results. This combination is a go-to for stylists aiming for excellence in tone-on-tone colouring and hair health, using a professional hair colour activator trusted worldwide.

Professional Application Guide: How to Use L'Oréal Dia Activateur Developer

For optimal results and to ensure client safety, always follow the specific mixing ratios and application instructions provided with your L'Oréal Professionnel Dia Light or Dia Richesse colour tubes. A skin allergy test should always be conducted 48 hours prior to application.

  1. **Preparation & Mixing:** In a non-metallic bowl, carefully measure and mix the L'Oréal Dia Activateur Developer 9 Vol 2.7% with your chosen L'Oréal Dia Light or Dia Richesse tone-on-tone colour. Adhere strictly to the recommended mixing ratio (typically 1:1.5 or 1:2, consult colour instructions on the specific colour tube).
  2. **Application:** Apply the mixture evenly to dry, unwashed hair (or towel-dried hair for Dia Light, depending on desired effect and hair condition). Ensure complete saturation for uniform colour penetration. Respect the recommended development time, which can vary (e.g., 5 to 20 minutes) based on the desired result and specific Dia product.
  3. **Rinsing & Aftercare:** Once development time is complete, gently emulsify the colour with a little warm water. Rinse hair thoroughly until the water runs clear. Shampoo twice with a dedicated post-colour shampoo, such as L'Oréal Professionnel Vitamino Color Shampoo, to seal the cuticles and prolong colour vibrancy. Finish with a conditioner or mask for optimal hair health.
