Garnier Olia Permanent Hair Color 8.0 Medium Blonde, Ammonia-Free Oil-Powered Formula, 2 Count — 100% Gray Coverage & Extra Shine

Garnier Olia 8.0 Medium Blonde is an ammonia-free permanent hair dye that uses a 60% oil-powered formula to deliver vivid, long-lasting medium blonde color with 100% gray coverage and up to 3× shinier-looking hair.

This two-count kit contains everything needed for an at-home permanent color service: developer applicator bottle, colorant tube, after-color conditioner, gloves and instructions. Olia replaces harsh ammonia with a blend of natural flower oils (sunflower and camellia) to help color penetrate the hair fiber while limiting the intense odor and dryness associated with traditional permanent dyes. The result is a glossy, hydrated finish and a shade that holds its vibrancy through routine washing when paired with color-protecting products.

How does the oil-powered formula affect my hair's appearance?

The oil-rich blend in Olia is designed to help color molecules reach deeper into the hair shaft without relying on ammonia. This helps hair look smoother and reflect more light, producing a noticeable shine after coloring.

• 60% oil blend (sunflower and camellia) for improved slip and conditioning.
• Less harsh odor than ammonia-based dyes.
• Formula aims to leave hair feeling hydrated and silky post-color.

Will Garnier Olia cover gray hair completely?

Yes — when used as directed, this permanent dye delivers full gray coverage across treated areas. The formulation and developer work together to lift and deposit pigment for uniform results on natural gray or regrowth.

• Promised 100% gray coverage for typical usage.
• Permanent color technology for long-lasting results.
• Best for full-head coverage, root touch-ups, or refreshing fading color.

What does the kit include and how do I apply it safely?

Each box provides the essentials to complete an at-home application: a developer bottle with applicator, a tube of colorant, an after-color conditioning treatment, gloves and step-by-step instructions. Follow the included directions for mixing, timing, and rinsing to achieve consistent results and minimize irritation.

• Mix colorant into developer bottle, shake, and apply to dry, unwashed hair.
• Process for the recommended time (typically around 30 minutes), rinse until water runs clear, then condition.
• Use gloves, conduct a patch test if sensitive, and follow safety guidelines in the leaflet.

How long will the medium blonde shade last and what maintenance helps it stay vibrant?

This permanent shade is formulated to remain visible through normal washes; longevity depends on hair porosity, prior color, and care routine. Using sulfate-free, color-safe shampoo and conditioner will help maintain tone and shine.

• Permanent color designed to resist washing fade for weeks with proper care.
• Pair with Garnier Fructis Color Shield Shampoo and Conditioner for extended vibrancy.
• Limit heat styling and use UV/protection products to preserve tone and sheen.

Who is this for: Garnier Olia 8.0 Medium Blonde is suited for anyone seeking a salon-quality permanent blonde at home without ammonia — from first-time at-home colorists to regular touch-up users. It’s a practical choice for people wanting full gray coverage, improved shine, and a formula that leans on plant-derived oils and a vegan, cruelty-free claim. Choose one box for short to medium hair; this two-count pack covers longer hair or provides an extra kit for future touch-ups.
