Like Pouring Milk on Your Head
This is the thinnest hair color I have ever purchased. It runs all over the place and isn't remotely red - more like a dark redwood color. Very dark. Waste of time and money.

Darkest brown
My favorite thing about this hair dye is that it’s a cream, so it doesn’t run all over the place. Darkest brown is a perfect natural looking black. (Top is my natural hair color and bottom is darkest brown.)

Incredible texture after application, long-lasting color.
[This review was collected as part of a promotion.] This dye didn't burn my scalp or damage my hair; it left it feeling soft, and the color lasted a long time. It doesn't have a strong smell, and the instructions make it quite easy to apply.

Horrible root/grey coverage. Not vibrant color like photos- disappointing and would not use again or recommend

Sarah thank you for letting us know. We’re sorry the Olia 4.62 - Dark Garnet Red didn’t look as vibrant as you expected from the photos and that you weren’t satisfied with the root/gray coverage We know how disappointing it can be to look forward to a new application of color only to find that your results are not what you expected. There are many reasons why haircolor results can come out so differently. If you would like to speak to us directly about your recent purchase, give us a call @ 800-631-7358 M-F 9 am-5:30 pm ET

the color mix is very watery and no gray coverage. the amount of color in one box is enough for a short (just below ear) and thin hair

Hair looks shiny healthy, and beautifully blended.
[This review was collected as part of a promotion.] The application was easy and the hair color came out beautiful and natural looking. It was just slightly lighter than expected but overall love it. I would definitely use it again..

Great product
[This review was collected as part of a promotion.] The smell is great, it was an easy application, rinsing and overall processing was not too bad. The processing time was fairly quick would recommend.

Does not cover grays
I'm a medium brown & have some baby grays on my temple that curl out, so I wanted to try this dye that says 100% gray coverage. I got the medium golden for a summer look... it didn't even tint the grays. I took me 20 minutes to apply throughout my hair, then 30 minutes to leave the dye in... Grays are still visible & I look more like a red head.

Hello VK! We are so sorry to hear that the Garnier Olia Brilliant Color - 5.3 Medium Golden Brown did not provide the gray coverage or the shade result you were hoping for. Stubborn gray hairs, particularly around the temples, can sometimes be more resistant to color absorption, and a helpful tip for better coverage is to apply a little extra product directly to those specific gray areas first and gently press it into the hair before processing. We truly appreciate you sharing your experience with us, and we will gladly pass your feedback along to our product development team.

Burned my skin!
I was surprised when this highly rated dye gave me chemical burns on my forehead and back of my neck. I’ve used so many box dyes and this has never happened to me before, and I have sensitive skin too. I even wiped excess dye off right away that was on my skin.

Applied the dye but no use. It didn’t serve the purpose. After applying in the dye and stayed for hours and washed the hair. The result my hair was white it didn’t turn back . I regularly use only this brand but this time it’s a big disappointment

Hello Raj! We are so incredibly sorry to hear about your disappointment with this application, especially as a loyal Garnier Olia user. For the best result and to protect your hair, our permanent oil-powered dyes are carefully formulated to process within thirty minutes, as leaving the mixture on for several hours can cause the formula to dry out and stop working properly, preventing the color pigments from penetrating the hair shaft. A helpful tip for your next application is to apply the freshly mixed black cream directly to clean, dry hair, ensure complete saturation of all grey or white strands, and set a timer to rinse thoroughly after exactly thirty minutes for beautiful, full-coverage results.

Awful
This stuff is actually terrible. It does not cover ANYTHING, let alone natural hair color. I wanted a color to cover to my roots and tried something new, but this stuff is hot garbage and did NOT cover my roots. I even waited the full 30!

I was suspicious when the directions only had the dye on my head for 30 minutes total and no directions for grey coverage. As I feared it did not cover the grey and for some reason I’m having the hardest time washing the dye out of my hair. I washed twice and I can still feel it in my hair.

Hello AK! We are so sorry to hear about your frustrating experience with your grey coverage and rinsing our Olia Light Brown dye. For optimal grey coverage with our ammonia-free, oil-powered formula, it is important to apply the mixture to your most resistant greys first and let it develop for the full thirty minutes, ensuring the hair is completely saturated. Because Olia's nourishing formula is packed with sixty percent natural flower oils, a great tip to easily rinse it out is to add a small splash of warm water and massage your scalp thoroughly to emulsify the oils before performing a deep, thorough rinse until the water runs completely clear.

5 out of 10.
This was a 5 out of 10 for me. The price was great. The color was dull. The conditioning of my hair with this wasn't as advertised on the box. And did not like the color so much.
