Perfect and vibrant
Ordered Black 1.0, and it came out just how I wanted. The perfect black, my hair feels healthy still and the shine is beautiful. The box does say that it’s not recommended for highlighted hair, but my hair was lightly highlighted and it covered it perfectly. Also had quite a few grays coming in and I don’t see them now. Just a tip if you’re not familiar with dying your hair yourself, you’re going to want to rinse your hair more than twice in the shower. If it runs clear and you think you’re done, think again. Also another tip: the first time styling your hair, the black will run off on your hands, and possibly your bedsheets or pillowcase. It’s not a defect in the hair dye itself, it’s just a result of dying in your hair black with any brand of hair dye. But I do love it!! I definitely recommend. **UPDATE** Just wanted to update that black has not faded yet, which I have experienced pretty quickly in the past with other dyes. I’ve washed my hair about five times already with color safe shampoo & conditioner, and the color is still vibrant! Updated photo is the one with straight hair.

A quality hair dye, with quality results!
I love Garnier Hair Color Olia, in the variant Golden Brown. I have naturally medium brown hair. This hair dye slightly lightens my natural color by a few shades, akin to using "Sun In." This product, however, has been very safe to repeatedly dye my hair with. I could use it every two or three weeks with no issues (although, I stick to about four weeks). However, it is also safe if you'd like to mix in "LIW pH mix." I personally used this with my dye - I added this liquid into the colorant bottle and slightly mixed it before applying the dye. This is not required; I do this as an extra step to make my hair softer and perhaps protect it more (and it is a separate purchase, just to clarify). This dye has multiple benefits. The smell is pleasant and not harsh. Additionally, I don't notice much fall out at all. I could leave this in my hair for 30-40 mins, rinse out, and my hair feels like it's in great condition (although I do use a conditioning shampoo and conditioner afterwards.) And with gray coverage? I had quite a bit of gray hair - I am in my mid 20s, so not all gray yet, but a good amount. This dye did cover most of my grays, and now it is impossible to tell that I had as much gray hair as I used to. Any drawbacks to this product? Not that I can think of! I use one box to dye my hair with, although my hair is medium length, which means if your hair is longer, you'll benefit from using two boxes. I have repurchased this product multiple times. I've been told that it's hard to tell that I'm using box dye. This is a great quality dye for the price point, but I cannot guarantee the results you'll receive if dyeing predominately gray hair. This product allows for root touch-ups or full coverage; in the latter case, you'd likely be dyeing your entire head of hair every 4-6 weeks to cover grays, while using a color-safe shampoo of your choice to extend the color.

Nice color but fades quickly
Easy to use but fades pretty quickly. Great color when it's freshly applied

No ammonia
I always use the Olia coloring for my hair as it has no ammonia and is gentle in my skin No reactions and the coloring stays for 3-4 weeks Good for covering up your greys

I bought this one for my mother and the truth is that it is very good, it leaves your hair with a quality color, soft and with a pleasant smell.

Just doing roots
Garnier is very good but if you only color like I do every 4 months the color does fade.
