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

Garnier Olia 5.03 is an ammonia-free, oil-powered permanent hair dye that delivers rich medium neutral brown color with 100% gray coverage and up to three times more shine.

If you want salon-level permanent color at home without ammonia, this two-count kit uses a 60% natural oil blend to deposit vivid pigment while leaving hair feeling smoother and glossier. The formula pairs sunflower and camellia flower oils with Olia’s color system so pigments penetrate deeply, reducing dullness and unwanted bite from traditional dyes. Each kit contains everything needed to color roots or full lengths: developer applicator bottle, colorant tube, after-color conditioner, disposable gloves, and step-by-step instructions.

How will Olia 5.03 change the look and feel of my hair?

You can expect an even medium neutral brown tone that covers gray hairs fully and adds visible shine. The oil-rich base helps colorants spread without dripping and leaves strands feeling hydrated, not stripped.

• 60% oil-powered formula for reduced dryness and added gloss
• Designed to deposit even, long-lasting pigment across hair fibers
• Includes after-color conditioner to smooth and seal cuticles

Is this safe for sensitive noses and free from harsh chemicals?

Olia omits ammonia, which cuts down on the strong chemical odor typical of many permanent dyes. It also avoids silicones and parabens, offering a gentler at-home coloring option while still providing permanent results.

• No ammonia in the developer for a milder application experience
• Formulated without parabens and silicones
• Plant-based flower oils help mask strong dye smells

How do I apply the color at home for best results?

Apply Olia to dry, unwashed hair for optimal coverage. Mix the colorant tube into the developer applicator, shake well, apply evenly to roots first for touch-ups or root-to-ends for full color, then leave to process as directed before rinsing and conditioning.

• Mix colorant into developer bottle; shake thoroughly
• Process time and rinsing instructions included in the packet
• One to two boxes for short–medium hair; two to three boxes for long hair

Will Olia cover gray hair and how long does it last?

This permanent formula is formulated to cover gray hair completely with natural-looking reflect and color depth. Expect long-lasting results that maintain vibrancy with color-safe care and occasional touch-ups at the roots.

• Formulated for full gray coverage with permanent pigment
• Color longevity depends on hair porosity and aftercare routine
• Use color-protecting shampoo and conditioner to extend vibrancy

Who is this for: Garnier Olia 5.03 suits anyone seeking a permanent medium neutral brown without ammonia and who prefers oil-enriched formulas for extra shine. It’s aimed at people who want an at-home solution with salon-level finish—ideal for first-time home colorists, busy adults needing reliable gray coverage, and anyone prioritizing gentler ingredients and visible shine.
