Loreal DIA Dark Brown 3

L'Oréal Professionnel DIA Dark Brown 3 is an ammonia-free, tone-on-tone hair colour for salon use. It works on the client's natural shade rather than lifting it, giving a soft, natural-looking dark brown with a shiny finish. In India this shade has been sold as DIA Richesse and, more recently, as DIA Color.

• Ammonia-free formula: a gentle, conditioning option for clients who want a softer colour service.
• Tone-on-tone result: deepens and refreshes the natural shade without lightening.
• Grey blending: suited to blending away first grey hairs. One retailer notes coverage works when up to about 70% of the hair is white.
• First-time clients: a good starting point for clients new to hair colour.
• Short development time: fits quick colour top-up services in a busy salon.

Mix and apply as per the L'Oréal Professionnel instructions on the pack, and do a skin allergy test before every service.
