Garnier Olia Hair Color - Oil-Powered

Dyeing your hair will never be the same again! Garnier Olia hair color is the first permanent hair color from Garnier formulated with oils. Free from Ammonia, this hair color is powered by oils to propel the color into the fibers of your hair instead. Olia is the new way to color your hair!

Olia 1.0 - Deep Black is a beautiful deep black hair color with 100% gray hair coverage that suits natural hair colors in different shades, from blonde to deep black. The result depends on your natural hair color. If in doubt between two shades, choose the lighter one.

Maximum color performance
100% gray hair coverage
Visibly improves hair quality
Optimal comfort for your scalp
Ammonia-free

Olia Hair Color with ODS-technology

The technology boosts the effect of the ingredients and removes the need to use ammonia and its harsh smell. The oil in Garnier Olia covers the hair and its surface. The high concentration of oil increases the level of alkaline substances in the hair fiber and enables the colorants to maximize the effect from within. Your hair looks healthier, shinier and feels softer. Keep in mind that shades with intense reflects (e.g., red shades) tend to provide less gray hair coverage than other shades.

In this kit:

1 cream developer tube 60 g
1 colorant tube 60 g
1 Silk & Shine after color treatment 54 ml
Gloves & instruction sheet

    ammonia hair dye

    Garnier Olia Permanent Color 110 Superlight Natural Blonde is a real hit! I love that it’s completely ammonia-free – it makes the coloring process so much more pleasant. The creamy consistency makes the color super easy to apply, and the best part is that it doesn’t get messy! The scent is fresh and floral, which is so lovely compared to other hair dyes. The result was a light blonde shade that feels natural and soft, just what I was looking for. My roots are a bit dark ash and they disappeared! My hair didn’t feel damaged at all, but I still recommend following up with a good hair mask to maintain moisture and shine. The color also holds really well! I’m participating as a test pilot via Smartson and received a free test product 🤩

    Golden light brown

    Good basic color, the scent is not strong. Easy to apply, the color matched my expectations realistically. I just wish for better color gloves.🙂 I received the product for testing from Smartson.

    Newly dyed & fresh

    The hair that was supposed to be dyed had strange greenish tones. I don't know how it could turn out like that, but it looked terrible. So I thought, now I will test this and see if it can do something. Said and done. Messy & messy. Vips, the green shimmering hair was gone, and instead, the hair had turned dark with shine. It felt so incredibly fresh. + easy to apply in the hair & the hair got really nice shine - one of the packages was hard to open This is a hair dye that I will use more times

    Garner Olia 7.40 Intense Copper

    The product instructions were clear and understandable. I think the color spread well in the hair and was economical, although one and a half packs would be optimal for my thick and relatively long hair. The scent was not overpowering, which is an absolute plus, as some colors have such a strong smell that they can't be used. I acted as a tester for Smartson and received a free product to try.

    GARNIER OLIA 1.0 NIGHT BLACK

    The instructions were clear and easy to understand. The color spread really well and was extremely economical compared to previous experiences / other hair dyes. The hair dye's scent was pleasant and could even be described as good. The color was easy to rinse out and the result was extremely good. Dry and damaged hair got shine and looked vibrant. I don't need to think about my next hair dye choice, it definitely went to the top! I acted as a tester for Smartson and received a free product to try.

    Makes hair smooth and great for reapplication

    I have been reapplying the same from last 3/4 applications, and it’s great for my touch up. Also it makes hair very smooth and silky. But it does not fully cover for grey hairs. Yet it is my go to hair color. 👍 👍

    Good hair color

    I got to test the product as a test pilot for Smartson. Good and easy-to-apply hair color. My hair is a bit longer than shoulder length, but one package was more than enough. However, I felt that the color started to fade a bit after a couple of washes, even though it is a permanent color.

    Good

    I got to test GARNIER OLIA 10.1 ASHY VERY VERY LIGHT in connection with Smartson. I chose the shade because it has the same number and description as the color I usually use. I think this one was totally okay, but nothing more. I started with the roots, which I let sit for 20-25 min. and then added it to the lengths and let it sit for another 10 min. I experienced that the color was very loose/thin in consistency, which made it easy to spill a few drops. I felt a bit of itching on my scalp during the coloring, and the itchiness lingered during the first day. When I rinsed out the color, my hair felt very rough, but fortunately, it hasn't dried out my hair so that it shows or feels. I hoped it would be more ashy in tone, but I was able to tone down the yellow with silver drops afterwards.

    Good red shade

    I received the product for free as a tester through Smartson. Very economical as one package was easily enough for my hair. Pleasant consistency, making it easy to apply evenly all over the hair. The scent was not too strong for my nose. It came off easily from the skin and surfaces while adhering well to the hair. Covered gray hair well. My original color was faded dark brown, and this brought a lovely deep red tone and a healthy shine to my hair. Conditioner included for multiple uses. Clear instructions and good protective gloves included. Based on my experience, I can also recommend it to others.

    Test pilot smartson

    Used the color (darkbrown 4.0) A product that was easy to apply and covered the whole hair. I usually need 2 packs to dye my long and thick hair, but with this product, only one pack was needed. Gave a nice natural result. Smells mild and also comes with an after-treatment that smells lovely. A product that I am very satisfied with and will use again. The pictures show before, during, and after the treatment. I am participating as a test pilot via Smartson and received a free test product.

    Seems fine, but has bleaching

    *I received the product for free in exchange for a review via smartson* I aimed for a color close to my own, and I am very satisfied with the result. I have a sensitive scalp, but it didn't irritate at all (except where I had a small sore, of course), no sharp smell, the accompanying hair treatment had a faintly quite pleasant scent. When I was about to apply everything, one part fell into the developer, but it didn't affect how easy it was to get the product out. But since it contains peroxide, which is bleaching (but used for color should penetrate well, is also found in Depends eyebrow color developer), I just want to inform people that this does wear out anyway. So if you use it too often, the hair quality will be affected. Maybe it doesn't do anything for most, but I have Hashimoto's hypothyroidism and my hair is always a bit worse than it could be, and you have to be careful if you want to have long hair. I can recommend this.
