Q: Can I mix the 8.0 medium blonde with the 7.0 dark blonde in a bowl? I am concerned 8.0 too light and 7.0 too dark.

submitted by pamelafs - 6 years ago
  • A: Your response! Really? "It makes no sense to even consider..." you say. Quite an opinionated and judgmental sentence to answer with as a professional representing Garnier. How about saying instead: "Best to try out one or both of colors you're considering so you know whether one is too light, or one is too dark since we do not recommend mixing of colors as it is hard to predict the results and even harder to replicate the results each time you color."

    submitted bypamelafs - 6 years ago
  • A: After your response to me on my question to you, I had to research one of your competitors who answered that exact same question I inquired of their 2 very similar dark and medium blonde colors. Their answer was: Yes, you can most certainly mix the two colors together to get a color that is best suited to your color desire. And that many of their customers did just that. And so.....I used their color instead and I was very happy with the results. If your OLIA ever changes its stance on their answer please let me know. I am aware that your hair formula is very nourishing, silky and gentle for the hair. Thank you. :

    submitted bypamelafs - 6 years ago
  • A: Wow, Garnier Consumer Care you really don't want customers do you. Very unprofessional response, making the consumer sound like they didn't have a valid question. Do us all a favor and go back to training

    submitted byAllyO - 3 years ago
  • A: Hi there Pamelafs! We are not fans of mixing colors. Its hard to predict the results and even harder to replicate the results each time you color. It makes no sense to even consider mixing until you have used the 2 colors you're considering, otherwise, how do you know if one is too light and one is too dark.

Q: My hair is dark brown w/grown-out old coloring that is light brown & I want to use one of the pink/rose quartz dyes. Garnier reps say that it's meant for undyed hair & that "special considerations" must be made for dyed hair. What product can I use?

submitted by LadyDianePoet - 5 years ago
  • A: Hi there! The Garnier Olia Bolds 7.20 Dark Rose Quartz is formulated to work on natural medium brown or lighter hair. Since your hair is dark brown there would be no noticeable change in your hair color. You would have to bleach your hair to a blonde shade and then apply the color. The product states not recommended on highlighted or bleached hair due to the intense color result that will be achieved. If you don't mind a more intense color than shown on the box, then bleach your hair first and apply the Garnier Olia 7.20 shade. Only bleach your hair if you feel your hair is in good condition before additional processing. Thank you!

Q: Is Olia permanent hair color hydrogen peroxide free? It says amonia free, but that does not necesarily mean peroxide free. Please advise as I can not use a hair color that contis hdroxogen peroxide

submitted by Twin - 5 years ago
  • A: Hi Twin, Thanks for reaching out! Olia Hair Color is Ammonia-Free, however it is formulated with Peroxide. Our hair color is an oil powered permanent hair color. We thank you for your interest in Garnier!

    submitted byGarnier Consumer Care - 5 years ago

  • A: Hi Twin! I don't see hydrogen peroxide in the ingredients. I would also recommend doing a patch test before using this hair color to be sure you're not sensitive to other ingredients, hope this helps :)

Q: Which color is darker the darkest brown 3.0 or the darkest platinum brown 3.11?

submitted by Marie - 5 years ago
  • A: Hi Marie! Shade 3.11 Darkest Platinum Brown is going to be the darkest shade, hope this helps :)

    submitted byTarget Beauty Consulting - 5 years ago
    Brand expert
  • A: Hi there Marie! Both colors are darkest browns so one is not darker or lighter than the other. The Olia shade 3.0, "Darkest Brown," is the natural version of the darkest of the brown shades and provides 100% gray coverage. It is best for anyone with natural hair between light brown and black. The Olia shade 3.11, "Darkest Platinum Brown," is the darkest of the brown shades with the addition of strong, ashy reflects for an intensely cool shade with a platinum, metallic-like shine. It also provides 100% gray coverage and is best for anyone with natural hair between light brown and black.

Q: Is medium brown darker or lighter than medium neutral brown?

submitted by CAM - 6 years ago
  • A: Hi Cam! Medium neutral brown is darker than medium brown. Hope this helps :)

    submitted byTarget Beauty Consulting - 6 years ago
    Brand expert
  • A: Hi there CAM! Actually, the medium brown 5.0 and medium neutral brown 5.03 are both medium brown colors so one is not any darker than the other. The medium brown 5.0 is the natural version of a medium brown and the medium neutral brown 5.03 has a slightly “cool” undertone and is a best choice for hair that tends to end up with unwanted reddish tones when dyed.

Q: Hi I have very light hair, a level 10 or 11 my natural hair color is really dark black. It naturally is a level 1 or 2. I was wondering if the shade 1.0 would help me get back to that? Also how long would it last?

submitted by Ally - 6 years ago
  • A: Hi Ally! You would need to fill the hair with red pigment first, then you would have better luck using a black dye. If you use a red toned brown first, then applied a level 1 or 2, you would have a better result. If you use a box dye, follow all directions on the box or in the information packet.

  • A: Hi there Ally! You can get back to all one dark color, however, going darker over highlighted/ bleached hair is tricky. To avoid odd discolored results on the bleached hair you need to custom mix 2 colors together to get a natural looking result.

Q: I have dark brown almost black hair naturally. I recently colored my hair with John Frieda foam color dark red. Didn’t show much. Looking to get a wine plum color, but not too too drastic. If I use the dark garnet red, what can I expect?

submitted by Kirmc - 6 years ago
  • A: Hi Kirmc! We recommend taking a look at the side of the box (can be viewed in product images next to the main product image), to get an idea of what kind a result you will get using this color over different shades of hair. We also recommend following the instructions included in the box.

  • A: Hi there! The Olia shade 4.62, "Dark Garnet Red" was specially designed with long lasting, deep red color with a hint of burgundy reflects. It is best for anyone with natural hair between light brown and black. (definitely check out the color cue on the side panel of any color you're interested in) Choosing a rich red is a great choice for dark hair like yours, the red tones are more likely to be noticeable against the natural dark hair.

    Brand expert
  • A: Hey there! Once the hair has been dyed black, the only colors that can be successfully used on that hair are black dyes. Dyed hair is much harder to lighten than natural hair. No hair dye is strong enough to lighten artificial pigment. To go lighter first you would have to have a salon professional strip out the dark dye first with a bleach lightener made for removing dark hair dye.

    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.)

    [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.

    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.
    1 reply from Garnier Consumer Care team - 2 months ago
    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!

    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
    1 reply from Garnier Consumer Care team - 2 months ago
    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.

    I got the vibrant red and it turned out very muted and coppery. Would not recommend. Barely even showed up

    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.
