Professional Use

L’Oréal Professionnel Dia Color 4 is designed for professional use. Always follow the manufacturer's instructions, wear appropriate gloves and complete the required allergy alert test before using hair colour.

Wear suitable disposable gloves and avoid using metallic tools. Apply Dia Color to dry hair following the recommended professional application method.

Mix 60ml of Dia Color colouring cream with 90ml of Dia Activateur, giving a 1:1.5 mixing ratio. Mix thoroughly in a non-metallic bowl or applicator bottle until a smooth, even consistency is achieved.

For a first application, apply to the roots, lengths and ends and allow to develop for 20 minutes. For regrowth applications, the colour can be taken through the lengths and ends according to the level of colour fade.

After development, emulsify gently, rinse thoroughly until the water runs clear and shampoo the hair.

Always follow the manufacturer's instructions on the product packaging and complete the required allergy alert test before use.
