Garnier Olia Permanent Hair Color 7.0 Dark Blonde — Ammonia-Free, Oil-Powered 2-Count for 100% Gray Coverage & Extra Shine

Garnier Olia 7.0 Dark Blonde is an ammonia-free permanent hair color that uses a 60% oil-based formula to deliver rich, long-lasting color with up to 100% gray coverage and enhanced shine.

Designed for at-home use, this two-count kit combines natural flower oils and a non-drip developer to infuse pigments deeply into the hair shaft while minimizing harsh odor and visible damage. The oil-forward system aims to leave hair feeling hydrated and looking glossier than untreated hair, and the kit contains everything needed for a full application: developer applicator, colorant tube, after-color conditioner, gloves, and instructions.

How does the oil-powered formula affect color and shine?

The formula contains a high proportion of natural flower oils that help carry color molecules into the hair fiber while smoothing the hair surface for extra gloss. Instead of relying on strong alkaline smells, the oil blend reduces odor and gives a more conditioned finish.

• 60% oil blend with sunflower and camellia oils for conditioning
• Propels dye deeper for even, vivid pigment
• Leaves hair up to visibly shinier than untreated hair

Will this cover my gray hair and how long does it last?

Olia is formulated to provide complete coverage of gray hair with natural-looking reflections and even tone. As a permanent dye, color longevity depends on hair porosity and care routine, but the product is made to retain vibrancy for weeks when used with color-safe products.

• Designed for 100% gray coverage across shades
• Permanent color that resists fading with proper maintenance
• Best results when paired with color-protecting shampoo and conditioner

How do I use the kit safely and effectively at home?

Application is straightforward: mix the colorant into the developer bottle, shake, and apply to dry, unwashed hair. Leave on according to the included timing guidelines, rinse until clear, and finish with the after-color conditioner to seal and soften the hair cuticle.

• Mix colorant into developer, shake well before use
• Apply to dry hair, process for the recommended time (about 30 minutes)
• Rinse thoroughly and use the included conditioner to restore moisture

How many boxes do I need for different hair lengths?

Coverage depends on hair length and thickness: one box typically covers short to medium hair, while longer or thicker hair may require multiple boxes to ensure full saturation and consistent color from roots to ends.

• Short to medium hair: 1–2 boxes
• Long or very thick hair: 2–3 boxes recommended
• Consider an extra box for very dense or multi-tonal applications

Who is this for: Garnier Olia 7.0 Dark Blonde is aimed at people who want a permanent at-home color without ammonia and prefer a formula that emphasizes conditioning and shine. It suits those seeking reliable gray coverage, a gentler scent profile during application, and a vegan, cruelty-free option for everyday color refreshes or touch-ups before events.
