Hair colouring has evolved tremendously in the past decade—and INOA by L’Oréal Professionnel stands at the forefront of that innovation. If you’re searching for a gentle, odourless, and ammonia-free hair colouring solution, INOA could be your perfect match.

At Vida Hair & Beauty in Chalk Farm, we’re proud to offer INOA colour services, ideal for clients who prioritise scalp comfort, hair health, and vibrant results.

What is INOA Hair Colour?

INOA (Innovation No Ammonia) is a permanent hair colour system developed by L’Oréal. It replaces harsh ammonia with an Oil Delivery System (ODS²) that:

  • Deposits pigment evenly

  • Protects the scalp

  • Respects the hair’s natural balance

  • Leaves hair glossy, soft, and healthy-looking

How INOA Works: The Oil Delivery System

Unlike traditional dyes that rely on ammonia to open the hair cuticle, INOA uses oils to gently guide colour pigments into the hair shaft. This revolutionary process:

  • Minimises scalp irritation

  • Preserves hair’s natural moisture

  • Eliminates harsh chemical odour

Clients often describe the process as “gentle and refreshing”—perfect for those sensitive to traditional colouring methods.
