## Long description

Garnier Olia 4.12 Iridescent Dark Brown is a permanent hair color solution that utilizes an ammonia-free formula to deliver vibrant, long-lasting results. By incorporating a high concentration of floral oils, this hair dye works to improve the overall quality of the hair while providing deep, multi-dimensional color. The iridescent undertones within this dark brown shade offer a sophisticated finish, ensuring that hair remains soft, shiny, and healthy-looking after the coloring process.
Advantages
The primary benefit of this hair color is its oil-based delivery system, which replaces traditional ammonia to provide a more pleasant coloring experience without a harsh chemical odor. The inclusion of floral oils helps to nourish the hair fiber during the application, resulting in improved texture and visible shine. Users can expect reliable gray coverage and a rich, deep color that resists fading over time, all while maintaining the natural suppleness of the hair.
Suitable for
Achieving a permanent dark brown hair color with iridescent reflections.
Individuals looking for an ammonia-free coloring alternative.
Those seeking to improve hair softness and shine during the dyeing process.
Home application for professional-looking results.
When it may not be suitable

How to use
Begin by performing a skin allergy test 48 hours before application. Mix the developer and colorant cream in the provided applicator bottle until the mixture is smooth. Apply the product evenly to dry, unwashed hair, starting at the roots and working through to the ends. Leave the mixture on for the duration specified in the instructions, then rinse thoroughly with warm water until the water runs clear. Follow up with the included conditioner to lock in moisture and shine.
What to consider before purchase
Check the current shade of your hair to ensure the desired result is achievable.
Verify that you are not allergic to any ingredients by performing a patch test.
Ensure you have enough product if your hair is long or very thick.
Usage recommendations
For the best results, avoid washing your hair for 24 to 48 hours after coloring to allow the pigment to fully set. Use color-safe shampoos and conditioners to maintain the vibrancy of the iridescent dark brown shade.
