L'Oréal Professionnel Dia Light 4 Brown 50ml Demi-Permanent Hair Colour

Dia Light 4 Brown deposits a medium brown shade with a glossy finish, making it a choice for refreshing faded brunette lengths or taking lightened hair to a deeper brown. As a level 4 shade, it adds noticeable depth to blonde hair rather than simply neutralising brass, so consider the starting colour before application.

Key Benefits

• Acidic demi-permanent hair colour designed to tone, refresh and gloss previously coloured or lightened hair.
• Level 4 Brown delivers a medium brown result for a brunette refresh or a deeper change on lighter hair.
• Ammonia-free toner option for professional colour services.
• Can help refine the appearance of unwanted warmth while adding brown tone; the result depends on the hair’s starting shade and condition.
• Suitable for salon hair colour work when a glossing service is required.

For a client seeking hair toner services in Australia, a colourist can assess the underlying shade and porosity before choosing this brown gloss. On brassy blonde, 4 Brown can create a substantially deeper medium brown result, so professional consultation and application are recommended. Use according to L'Oréal Professionnel directions for salon colour.
