Whether you’re covering grays or refreshing your look, Olia’s vibrant, long-lasting color is a game-changer. Trust me, your hair deserves this! Read on for my experience, pros, cons, maintenance tips, and how it stacks up against other brands.
My Experience With Garnier Olia Hair Color
I’ll admit, I was nervous about coloring my hair at home.
Past box dye disasters left me skeptical—patchy results, fried ends, and that awful chemical smell.
But salon prices in the city?
Ouch.
After scouring reviews, I landed on Garnier Olia in 6 1/2.3 Lightest Golden Brown, hoping its ammonia-free, 60% oil blend would be kinder to my hair.
Spoiler: it was a total win.
The kit comes with everything you need: developer, colorant, conditioner, gloves, and clear instructions. I started by mixing the colorant and developer in the applicator bottle. The velvety cream texture was a breeze to work with—no drips, no mess.
Unlike other dyes, there was no harsh ammonia stench, just a pleasant floral scent that made the process feel almost spa-like. I applied it to my roots first, letting it sit for 15 minutes, then worked it through the rest of my hair for another 25 minutes, as suggested for my medium-length, dark blonde hair.
Rinsing was easy, and the included conditioner felt luxurious, leaving my hair soft and hydrated. When I blow-dried, I couldn’t believe the results. The color was a stunning ashy brown with golden undertones—exactly what I wanted.
It covered my stubborn grays completely, and my hair looked shinier than ever, almost like I’d just left a salon. Weeks later, the color still looked vibrant, with no noticeable fading. I’ve since set up a subscription to keep this shade on hand, and I’m never going back to salon visits or other box dyes.
Olia’s ease, quality, and gentle formula have me sold.
Pros of Garnier Olia Hair Color
- Ammonia-Free Formula Feels Gentle
Olia’s ammonia-free formula is a standout.
Unlike traditional dyes that sting your scalp and leave your hair brittle, this one uses a 60% oil blend with sunflower and camellia oils.
My hair felt nourished, not stripped, after coloring.
The lack of ammonia also means no harsh chemical smell—just a light, floral fragrance that makes application pleasant.
If you’ve got a sensitive scalp or hate that nose-burning scent, this is a huge plus.
- Vibrant, Long-Lasting Color
The color payoff is incredible. Shade 6 1/2.3 Lightest Golden Brown gave me a rich, ashy brown with golden tones that looked natural yet polished. It’s formulated to propel color deep into the hair, ensuring even coverage and up to 100% gray coverage.
My grays were gone, and the color stayed vibrant for weeks without fading into that dull, brassy tone you get with lesser dyes. It’s permanent, so it lasts until your roots grow out.
- Healthier, Shinier Hair
Olia doesn’t just color—it improves your hair. The oils reverse roughness and dullness, leaving hair hydrated, silky, and up to three times shinier than uncolored hair.
After using it, my hair felt softer and looked glossier, like I’d used a high-end conditioning treatment. This is a big deal if you color regularly and want to avoid that dry, damaged feel.
- Easy Application Process
The non-drip, velvety cream formula makes application foolproof. The applicator bottle is easy to grip, and the dye spreads evenly without running. Whether you’re a newbie or a seasoned at-home colorist, you’ll find it simple to use.
The kit’s gloves and instructions are clear, and there are even QR codes linking to how-to videos for extra guidance. I had no stains on my skin or bathroom, thanks to the precise application.
- Vegan and Cruelty-Free
Olia is Leaping Bunny certified, cruelty-free, and vegan, with no animal-derived ingredients. It’s also free of parabens, silicones, and phthalates, making it a cleaner choice for those who prioritize ethical and eco-friendly products. I felt good knowing my hair color aligned with my values without sacrificing quality.
Not-So-Good Parts of Garnier Olia Hair Color
- Quantity Issues for Long or Thick Hair: If you’ve got long or thick hair, one box might not cut it. I have medium-length hair, and one kit was just enough, but I can see how someone with longer or denser hair might need two. This bumps up the cost, and some retailers limit purchases to one box, which is frustrating. Plan ahead and grab an extra kit to avoid running out mid-application.
- Applicator Bottle Can Be Slippery: The applicator bottle’s oval shape looks sleek, but it can get slippery when your gloved hands are wet. I fumbled it a couple of times, though I didn’t drop it. If you’re used to standard bottles, it might take some getting used to. Using your own gloves or a different bottle could help if this bothers you.
- Color May Vary Slightly: While my color turned out as expected, some users report the shade looking darker or lighter than the box, especially if your hair is previously color-treated. My natural dark blonde hair took the dye perfectly, but if you’re coming from a dyed base, test a strand first or use Garnier’s Shade Selector Tool to avoid surprises.
- Greasy Residue for Some: A few users mentioned a greasy feel after rinsing, likely due to the high oil content. I didn’t experience this, but if you do, washing with a clarifying shampoo post-coloring can help. Be sure to rinse thoroughly and use only a small amount of the conditioner to avoid weighing your hair down.
Maintenance Tips For Garnier Olia Hair Color
- Use Color-Safe Products: To keep your Lightest Golden Brown vibrant, switch to a color-safe, sulfate-free shampoo and conditioner. I use Garnier’s Sleek & Shine line, which keeps my color looking fresh and my hair hydrated. Sulfates can strip dye, causing fading, so check your labels. Wash your hair less often—every other day works for me—to preserve the color longer.
- Protect from Heat and Sun: Heat styling and UV rays can dull your color fast. I always apply a heat protectant before blow-drying or curling, and I wear a hat or use a UV-protectant spray when I’m out in the sun. This keeps the golden tones from turning brassy and maintains that salon-fresh shine.
- Deep Condition Regularly: Olia’s oils leave your hair hydrated, but regular deep conditioning keeps it in top shape. I use a moisturizing mask once a week, focusing on my ends, which tend to dry out. This prevents split ends and keeps my hair silky, especially since I color every six to eight weeks.
- Touch Up Roots Strategically: Since Olia is permanent, you’ll only need to touch up roots as they grow. I reapply every six weeks, focusing on my roots for 15 minutes before pulling the dye through the rest of my hair for a quick refresh. This saves product and minimizes overlap, which can dry out your lengths.
- Remove Stains with Micellar Water: If you get dye on your skin (it happens!), Garnier’s Micellar Water (Waterproof) is a lifesaver. I dab it on with a cotton pad to lift stains from my forehead or ears without scrubbing. Keep some on hand for quick cleanups during application.
Comparison of Garnier Olia Hair Color With Other Brands
I’ve put Garnier Olia Hair Color head-to-head with three popular at-home dyes: L’Oréal Paris Excellence Crème, Garnier Nutrisse, and L’Oréal Superior Preference. Each has its strengths, but Olia’s unique formula makes it stand out.
Let’s break it down so you can see how Olia compares on key factors like formula, application, color payoff, and hair health.
- Garnier Olia Vs. L’Oréal Paris Excellence Crème
L’Oréal Paris Excellence Crème is a heavyweight in the hair dye world, known for its robust gray coverage and vibrant shades.
But when I used it, the ammonia-based formula was a dealbreaker. That harsh chemical smell hit me hard, and my scalp felt slightly irritated during application.
Olia, being ammonia-free with a 60% oil blend, was a breath of fresh air—literally. Its floral scent and gentle feel made the process feel like a treat, not a chore.
Excellence Crème left my hair vibrant but noticeably drier, while Olia’s oils gave me a silky, shiny finish that lasted weeks.
L’Oréal’s applicator is precise, but Olia’s non-drip cream is easier to control, especially for beginners. Price-wise, Excellence Crème runs about $12, while Olia’s around $10, making Olia the better value for gentler, shinier results.
- Garnier Olia Vs. Garnier Nutrisse
Garnier Nutrisse, Olia’s sibling, is another fan favorite, and I’ve used it for bold reds in the past.
Nutrisse uses ammonia and a blend of five fruit oils, delivering rich, fade-resistant color.
It’s great for longevity—my red stayed vibrant for nearly seven weeks—but the ammonia made my eyes water during application, and my hair felt less hydrated than with Olia.
Olia’s oil-powered, ammonia-free formula left my hair shinier and softer, with a more natural-looking Lightest Golden Brown.
Both are easy to apply, but Nutrisse’s cream is slightly thinner, which can lead to drips if you’re not careful.
Nutrisse is a solid pick for intense shades, but Olia wins for gentleness and that glossy, salon-like finish. Both are priced similarly, around $10, so it’s about prioritizing health over boldness.
- Garnier Olia Vs. L’Oréal Superior Preference
L’Oréal Superior Preference promises “fade-defying” color with a luxurious feel, and it delivers on vibrancy.
When I tried it, the color was stunning, but the ammonia-based formula was harsh, leaving my hair a bit straw-like despite the included conditioner.
Olia’s ammonia-free, vegan formula, packed with sunflower and camellia oils, felt like a spa treatment in comparison.
My hair was noticeably shinier and softer after Olia, while Superior Preference needed extra conditioning to combat dryness.
Application-wise, Superior Preference’s gel-like formula is trickier to work with—it dripped a bit—while Olia’s velvety cream stays put.
Superior Preference offers more shades, but Olia’s 100% gray coverage and healthier hair outcome make it a stronger choice for regular colorists.
At around $11, Superior Preference is slightly pricier than Olia’s $10, but Olia’s gentler formula and ease of use make it the smarter buy.
Frequently Asked Questions (FAQ)
Yes, Olia is gentler than many dyes. Its ammonia-free, 60% oil blend with sunflower and camellia oils nourishes hair, reducing roughness and boosting shine. Unlike ammonia-based dyes, it doesn’t strip your hair or irritate your scalp, making it a healthier choice for regular coloring. My hair felt softer and looked shinier after using it.
Olia is a permanent dye, lasting until your hair grows out or is cut. Typically, the color stays vibrant for six to eight weeks, though it may fade slightly with frequent washing. I noticed my Lightest Golden Brown stayed rich for about six weeks before needing a root touch-up.
Olia is less damaging than ammonia-based dyes. The oil-powered formula respects your hair’s natural amino acids and lipids, minimizing dryness and breakage. While no dye is 100% damage-free, my hair felt hydrated and healthy post-coloring, with no signs of brittleness or split ends.
Garnier Olia is among the healthiest due to its ammonia-free, vegan, and paraben-free formula. Other contenders include Clairol ColorStrong (ammonia-free but fades faster) and Tints of Nature (organic but pricier). Olia’s oil blend and cruelty-free status make it a top pick for vibrant, low-damage color.
