Garnier Olia Permanent Hair Dye, Up to 100% Grey Hair Coverage, No Ammonia, 60% Oils, Midnight 2.0 Black Diamond

This is a great hair dye.the colour is lovely.Very pleased with the product.Will carry on using it as it’s the best I have used so far.Its gentle on the scalpcompared to other products.

Have used this for a while.Really like the colour on my grey/light brown hair.Doesn't dry your hair too much.

Helps condition and add shine during the coloring process. Hair feels softer and looks glossier compared to many other drugstore dyes.

Usually use 8.13 which is a lovely colour, but wanted to go a bit darker so roots don't contrast so much when it grows out. My hair was naturally a golden dark blond, but can't find any "golden" hair dyes that don't turn my hair ginger, so now stick with the ash tones. 7.13 has mainly bad reviews that I've seen, but gave it a go anyway. Like one review I saw, I agree that it does actually have vaguely green and grey tones and takes a bit of getting used to, but I kind of like it. Green suits me better than ginger and it will probably fade to a nicer colour like the 8.13 does after a few washes.

I have long, thick naturally curly hair. My hair is very dry so have to use nourishing products and was recommended this.I have never dyed my hair at home before as always had a full head of foils every 6 weeks, 90% of my hair was highlighted with high lift tint and I have alot of white/grey hair.Due to unforseen circumstances I couldn't get it coloured and decided to take the plunge! As I'm aware how much dye my hair takes (as it's dry, it sucks it up) plus I was going to completely re colour my hair to dark blonde! I brought 3 packs to be on the safe side. 2 packs covered 2/3 of my head (you can imagine my relief that I decided to buy that 3rd pack) I was able to give my hair a really good cover of dye.To my amazement (I had been stressing I would go orange) it covered everything! My white/grey and all the highlights, I have a lovely even toned head of hair.I will never go back now, I can touch up my roots as and when needed as once the tubes are open they need to be used within 12 months. This also allows you to complete skin tests by adding a little developer and color, mixing and applying with a cotton bud just behind the earThe colour is a dark blonde, exactly what I expected

Easy to apply and develops in 30 minutes

I bought Deep Rose in the efforts to turn my hair pink. I had previous bleached and used a rose gold crazy colour.I bought two boxes (my hair is shoulder bone length but quite thick). I didn't read any reviews, in hindsight, I should have done.My friend applied the dye which went on really well, covered everywhere and there was plenty with one box. I was impressed as it changed colour within minutes and you could see if there was any patches. I left it on for how long it said and washed it out how it said to. My hair was PATCHY it was almost like it had just washed out in certain places. After a few days, we used the other box just on the patches at first and then roots to finish. It took quite well and covered the original patches and now my hair is pink.My only issue now seems to be that it is washing out still. When I washed after dying, the water ran clear like it says to do. Every time I wash it, the water is slightly pink.Over all, I would use again, but only so I have the same colour on my hair and not a mix.

Does what it says on the tin.
