L'Oréal Professionnel Dialight is an acid gel cream tone-on-tone hair colour that doesn’t lighten or sensitise the hair, but fills it with moisture and condition for maximum shine.

Dialight is a versatile ammonia free colour that allows you to mix shades, and can be used with L'Oréal permanent colours (Majirel, Inoa or Luocolour) as part of a colour matching service. Dialight is ideal for coloured or sensitised hair as it offers zero lightening and delivers ultimate vinyl shine and condition.
