Garnier Olia Permanent Hair Color 1.0 Black — Ammonia-Free, Oil-Powered 2 Count for 100% Gray Coverage

Garnier Olia 1.0 Black is an ammonia-free, oil-powered permanent hair dye that delivers 100% gray coverage and up to three times shinier-looking hair with a gentle, non-drip cream formula.

If you want a salon-quality permanent color at home without ammonia, Garnier Olia uses a 60% natural oil blend to help carry pigments deeply into the hair fiber while keeping hair soft and hydrated. The kit contains everything needed for application—developer bottle, colorant tube, after-color conditioner, gloves, and instructions—so you can get even, long-lasting results in one session. Olia is vegan, Leaping Bunny certified, and formulated without silicones, parabens, or phthalates.

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

The oil-rich base helps the colorant penetrate evenly and leaves the hair surface smooth, producing richer color and enhanced light reflection. Rather than using strong-smelling ammonia, the sunflower and camellia seed oils support hydration, which can make hair appear glossier after coloring.

• 60% oil blend propels pigments into the hair shaft for even deposit.
• Non-drip cream texture makes application cleaner and more controlled.
• After-color conditioner seals cuticle for smoother, shinier results.
• Fragrance is floral and milder than typical permanent dyes.

Will Garnier Olia give full gray coverage and long-lasting color?

Olia is designed as a permanent dye, formulated to cover gray hair thoroughly and provide sustained color. Coverage and longevity depend on starting hair condition and care routine, but the product aims for reliable gray coverage and vibrant tones between touch-ups.

• Formulated for 100% gray coverage when applied per instructions.
• Permanent pigments resist fading; use color-safe products to extend vibrancy.
• One to two boxes cover short to mid-length hair; longer hair may need two to three boxes.
• After-care with Garnier color protection products helps maintain tone.

How do I apply Olia at home safely and get the best results?

Follow the provided instruction leaflet step-by-step for mixing, timing, and rinsing. Apply to dry, unwashed hair for first-time full-head coloring; for touch-ups, apply to regrowth first. Processing time is indicated in the kit—rinse until water runs clear and finish with the included conditioner.

• Mix colorant into developer bottle, shake to emulsify, and apply evenly.
• Wear gloves and work in sections for even coverage and minimal mess.
• Process as directed (typically around 30 minutes) before rinsing thoroughly.
• Use the included after-color conditioner to restore softness and seal color.

Is Olia suitable for sensitive scalps or ethical shoppers?

Olia avoids ammonia, silicones, parabens, and phthalates, which some users prefer for milder formulas. It’s vegan and Leaping Bunny certified, aligning with cruelty-free and animal-free ingredient standards. If you have scalp sensitivities, perform a skin allergy test and follow safety instructions before full application.

• Ammonia-free formula reduces strong odor and irritation for many users.
• Vegan and cruelty-free certification for ethical purchasing choices.
• Includes clear safety and allergy test guidance in the instruction sheet.
• Not formulated as a treatment for scalp conditions—consult a professional for concerns.

Who this is for: Garnier Olia 1.0 Black is made for people seeking a dependable, salon-inspired permanent black shade at home without ammonia, those who prioritize ethical and vegan formulations, and anyone who wants a smoother, shinier finish after coloring. It’s a strong option for first-time at-home colorists, regular touch-up users, and busy shoppers who want professional-looking results with a gentler-feeling formula.
