Garnier Olia 5.5 Mahogany Brown Permanent Hair Dye – Ultimate Rich & Luminous Colour

Garnier Olia 5.5 Mahogany Brown Permanent Hair Dye is a powerful at-home colouring solution for creating a rich, warm brown look enhanced with beautiful mahogany tones. This sophisticated shade combines a brown base with warm reddish reflects, giving hair a vibrant, multidimensional appearance. Garnier specifically describes 5.5 Mahogany Brown as a warm brown shade with rich, chocolatey tones and subtle golden glints.

Powered by Garnier Olia’s oil-based colouring technology, Garnier Olia 5.5 Mahogany Brown Permanent Hair Dye is designed to deliver intense, even and long-lasting colour without ammonia. The formula contains 60% oils within the colourant, helping maximise colour performance while leaving hair looking shiny and feeling nourished.

Rich Mahogany Brown Colour with Beautiful Warm Reflects

The Garnier Olia 5.5 Mahogany Brown Permanent Hair Dye shade is ideal for anyone looking to move beyond a basic brown and introduce more warmth and character into their hair colour. Its mahogany influence gives the brown base a sophisticated reddish warmth, while the chocolate-inspired tones create a deep, elegant finish.

The final result can vary according to your starting hair colour, which is why Garnier recommends checking the shade guide on the packaging before colouring. Olia shades are designed to work within the appropriate range of your natural base colour, and Garnier advises choosing carefully when moving between shades.

60% Oil-Powered Permanent Hair Colour

A major feature of Garnier Olia 5.5 Mahogany Brown Permanent Hair Dye is its Oil Delivery System. Rather than relying on ammonia, Olia uses an oil-powered colouring approach, with oils concentrated in the colourant itself to support the colouring process. Garnier states that Olia contains 60% oils and is formulated without ammonia for a more pleasant colouring experience.

This oil-powered formula is designed to provide maximum colour performance while visibly improving the look and feel of the hair. Garnier reports up to 3x more shine compared with unwashed hair in its instrumental testing.

Ammonia-Free Formula for a Pleasant Application

Garnier Olia 5.5 Mahogany Brown Permanent Hair Dye is formulated without ammonia. This helps provide a more pleasant scent during the at-home colouring process compared with traditional ammonia-containing permanent hair colours. Garnier also describes the colourant as having a velvety, non-drip texture designed for straightforward application.

The kit is designed as a complete home-colouring system, with colour cream, developer cream, applicator bottle, after-colour conditioner, gloves and instructions included, although exact packaging contents can vary by market.

Important Colour Safety and Application Advice

Before using Garnier Olia 5.5 Mahogany Brown Permanent Hair Dye, always follow the instructions supplied with the product and complete the required allergy alert/patch test 48 hours before colouring. Garnier explicitly recommends performing a patch test 48 hours in advance and discontinuing use if irritation or a reaction occurs.
