Garnier Olia Permanent Hair Color 5.03 Medium Neutral Brown, 2-Pack — Ammonia-Free, Oil-Powered for 100% Gray Coverage

Garnier Olia 5.03 Medium Neutral Brown is an ammonia-free permanent hair color that uses a 60% oil-powered formula to deliver vivid, long-lasting medium neutral brown with up to 100% gray coverage and enhanced shine.

This at-home hair dye kit is formulated with natural flower oils (sunflower and camellia) and an oil-driven developer to carry pigment deep into the hair shaft while minimizing odor and damage associated with traditional ammonia dyes. Each box contains a developer applicator bottle, colorant tube, after-color conditioner, gloves, and instructions so you can complete a full-color service at home. The formula is vegan and cruelty-free, free from parabens and silicones, and designed to leave hair feeling hydrated, looking three times shinier than untreated hair.

How does Olia's oil-powered formula change color results?

Olia replaces much of the water found in traditional dyes with a 60% blend of natural oils, which helps carry color molecules more effectively into the hair fiber while protecting the cuticle. The result is vivid, even color with a glossy finish and less of the strong chemical smell typical of ammonia formulations.

• 60% oil blend (sunflower and camellia) for pigment delivery
• Reduced odor compared with ammonia-based dyes
• Smoother, shinier-looking hair due to added hydration
• Non-drip, easy-to-apply consistency for even coverage

Will this shade cover gray hair completely?

Garnier Olia is formulated for reliable gray coverage; Expect up to 100% gray coverage, especially on short-to-medium lengths when used according to instructions. For stubborn or extensive grays, following the application steps closely and using the recommended processing time helps ensure complete, natural-looking coverage.

• Designed for full gray coverage up to 6 weeks
• Apply to root area first for touch-ups, or full-head for complete color
• Follow 30-minute processing time for best results
• One to two boxes for short-medium hair; two to three for long hair

How simple is the application for at-home use?

The kit includes everything needed and uses a straightforward bottle-and-tube mixing method so non-professionals can achieve consistent results. The developer bottle becomes the applicator, letting you saturate roots and lengths evenly; rinse and use the included after-color conditioner to lock in color and softness.

• Mix colorant tube into developer applicator bottle, shake well
• Apply to dry, unwashed hair—roots first for regrowth or full-head for total change
• Process for 30 minutes, rinse until water runs clear, then condition
• Disposable gloves and step-by-step instruction sheet included
