Garnier Olia Permanent Hair Color — 8.0 Medium Blonde, Ammonia-Free Oil-Powered Formula, 2 Count

Garnier Olia 8.0 Medium Blonde is an ammonia-free, oil-powered permanent hair color kit that delivers vivid, long-lasting medium blonde results with up to 100% gray coverage and noticeably shinier hair.

Designed for at-home colorists who want salon-worthy results without ammonia, this two-count kit uses a 60% natural flower oil blend (sunflower and camellia) to help the dye penetrate hair for even color and improved shine. The boxed set contains a developer applicator bottle, a colorant tube, after-color conditioner, gloves, and simple instructions—everything needed to color short to medium hair once or to touch up roots as required. Olia’s formula skips silicones and parabens and is formulated vegan and cruelty-free.

How does Olia achieve brighter, shinier color without ammonia?

Instead of relying on ammonia to open the hair cuticle, Olia uses oil-driven ODS Technology. A high concentration of natural flower oils helps carry color molecules into the hair shaft while reducing harsh scent and drying effects.

• 60% oil blend (sunflower and camellia) for improved color delivery
• Oil-powered non-drip formula for even application
• Less noticeable odor compared with ammonia-based dyes

Will it cover gray hair and how long does the color last?

Garnier Olia is formulated to provide up to 100% gray coverage with permanent results. Expect natural-looking reflections and sustained vibrancy when you follow the application and aftercare guidance, though longevity varies with hair porosity and maintenance routine.

• 100% gray coverage on tested grays for full-head applications
• Permanence depends on hair type and aftercare—use color-safe shampoo and conditioner
• Recommended touch-up schedule varies by regrowth rate and exposure

How do I use this kit safely and get even results at home?

The kit includes step-by-step instructions; read them fully before starting and perform a patch test 48 hours prior to use. Apply to dry, unwashed hair, processing for the directed time, then rinse until water runs clear and apply the included after-color conditioner to seal color and boost softness.

• Mix colorant into developer bottle, shake well, and apply with the applicator tip
• Process approximate time indicated in instructions (typically around 30 minutes)
• Rinse thoroughly, then use the post-color conditioner for best finish

What aftercare keeps medium blonde tones vivid and healthy-looking?

Use sulfate-free, color-safe cleansing and conditioning products and limit hot tools to preserve shine and reduce fading. Garnier recommends pairing Olia with color-protecting shampoos and conditioners to maintain tone and gloss between touch-ups.

• Use Garnier Fructis Color Shield Shampoo and Conditioner for maintenance
• Avoid excessive sun and chlorinated water without protection
• Schedule touch-ups based on regrowth and personal preference

Who is this for: Garnier Olia 8.0 Medium Blonde is aimed at people seeking an ammonia-free permanent color with rich medium-blonde results, especially those who prefer vegan and cruelty-free formulations. It’s a practical choice for first-time at-home dyers and experienced colorists wanting a gentler salon-style finish, suitable for covering gray, refreshing existing color, or changing shade. Choose two boxes for one full application on medium-to-long hair or for repeat touch-ups; one box may suffice for short hair or root-only work.
