Color fading out the hair after a week
The hair dye is starting to fade and is getting out of the hair and i dyed it last week this is a really bad product. I can see my blonde hair coming back but last week it was pretty dark but now it’s just getting blonder.

Best color I have used
Have been using this product for at least a year. I'm 70 yrs old. Don't know how grey I am because I always have dyed hair but it covers my hair completely No Greys! Hair is so shiny and soft. Olio lasts longer than other products I use. Only problem I have is can't find this shade locally I have to do mail order.

Excellent root coverage with no residue, leaving h
[This review was collected as part of a promotion.] I really enjoyed using Garnier Olia 2.0 Soft Black. The application was easy and smooth, and I loved that it has no ammonia. The scent was mild and not overpowering. It covered my roots evenly and blended perfectly with the rest of my hair, giving a very natural and rich black color. After rinsing, there was no heavy residue left on my scalp or hair, and my hair felt clean, soft, and nourished. The color looked glossy and healthy, covered my grays completely, and didn’t dry out my hair. Even after several washes, the color stayed vibrant with no dullness.

Ammonia free and smells good! But wasn’t my favori
[This review was collected as part of a promotion.] I think this was okay. It wasn’t my favorite but I like how there was no ammonia! We used it on my sisters hair and it didn’t dry it out. In fact, I was surprised that it looked pretty healthy still after!

4.0 will turn your hair off black.
I bought this based on seeing results on TikTok. It varies. I purchased 4.0 darkest brown and it was black. Yes, usually hat color is darker at first but usually after about 2-3 washes it shows its true color and I’ve had it for about 2 weeks and a half and nothing has shined through. Therefore, coverage was excellent but if you’re hoping for dark brown. You will 100% get black. At least an off black. I can only imagine how dark their black eyes are. Very pigmented. It evened out any brassiness I had to give it a more black hue. I am debating color oops’ing this off to see if I can lighten it. I think 3 shades lighter would have given me the results I’d want. This was coming from medium brown hair.

Best drugstore hair color for damaged hair.
Best hair color brand for damaged hair. Even color. Hydrating. No smell. No patchy but natural looking color. I haven’t found a healthier alternative hair color than this and I’ve tried several other brands which left my hair feeling like a straw.

I have used Garnier Nutrisse for over 25 years and could only find this new formula and not the old. It is awful. My scalp burns and itches. Having it applied now and don’t know how I will stand it for 30 minutes. Guess I will have to find a new brand. I’ll never buy again! Should have never changed the formula.

I wish there was a little more in each bottle. As soon as my hair hits my shoulders I have to get a second box. Color is good. I always get compliments.

Very helpful to someone!
I got the shade “DARKEST BROWN” and it exceeded my expectations! The before and after is very clear. My hair wasn’t a lighter brown. I love this color. I used 1 full bottle and 1/4 of another.
