Garnier Olia Soft Black Permanent Hair Dye, Up to 100% Grey Hair Coverage, NO Ammonia, 60% Oils - 3.0 Soft Black

Rich, natural looking light brown color with a glossy finish. Gentle, easy to apply, and long lastin, perfect for an at home refresh.

I use this shade regularly to touch up my roots, especially to cover greys, and it has worked really well for me. The colour 5.0 Brown gives a natural finish that blends nicely with the rest of my hair. The coverage is very good — it fully covers my greys and leaves a consistent colour without patchiness. Not having ammonia is a big plus for me, as the smell is much more pleasant during application and it feels gentler on my scalp. The conditioner included in the box is excellent. It leaves my hair feeling super smooth and soft with a really nice scent that lasts after drying. My hair looks shiny and healthy rather than dry. Overall, this is a reliable root touch-up option with strong grey coverage. I’ll continue repurchasing it.

Gorgeous coverage and shiny results after application. Easy to use and good value for money. The conditioner that comes with it helps keeps the colour vibrant.

I like the product, it was easy to apply. I'm out of practice with hair dyes, having not used a home kit for quite a while, so I was quite impressed that I didn't drip dye everywhere when I applied it. Also, it was fabulous not to have the eye watering ammonia on my head for half an hour. Plus, there was very little skin staining (although I did apply Vaseline to the hot spots on my ears and forehead/hairline. Less positive was that I wasn't aware that I would need two boxes for my mid length and average thickness hair on the first application The results were really patchy along the lengths of my hair with some areas where I'd clearly not applied enough. I had to buy a second box and reapply it. I'd like to think that now I have the "base colour", I wouldn't need to top up my colour with two packs in future, but I don't know about that one until I try it. Also, the resultant colour is a very reddish shade of purple and really quite dark on my mid brown hair. It's taken the shade of my hair to a much darker brown and the purple is not overly noticeable without having full light on it. It kind of just looks a very, very dark brown in dark lighting. I think I expected something a little more vivid on my hair based on the box images. It's a nice colour, don't get me wrong, but it's not very close to expectations and darker than I wanted. I might or might not choose this shade again, but I think the product itself is very good. I really don't know why manufacturers can't make our lives easier and produce a larger product size for first time applications or longer, thicker hair, instead of us needing to buy two boxes to get the results! Anyway, I've bought a different brand with a different purple to try once this colour fades; I don't doubt I'll be less impressed with the ammonia though!

Such a bright, stunning colour - I'm often complimented on my hair colour when it's recently been dyed with Olia 7:40. One pack is not enough for my thick hair, even after I've just had it cut to shoulder length, so I always buy two. But at this price, it's still way cheaper than getting a hairdresser to dye it, so I have no complaints about the price at all. The colour is vibrant, the product is easy to use, and it works very quickly. I have not had any issues at all with skin staining - with other brands in the past I've had coloured patches on my neck, face and forehead for a couple of days after dyeing my hair, but that never happens with this brand. The colour lasts a long time - it is permanent, though the vibrancy decreases a tiny bit with each wash. My natural hair colour is 'mouse' but this dye is so permanent, even when it's long-faded you can see the difference between my mousey roots and the dyed lengths. It fades to a soft peachy 'strawberry blonde' which I can live with quite happily.

Lovely colour rich and lasts but would definitely not recommend if you hair is bleached very light blonde as the colour fades very quickly

I'm sure the hair dye is great as I've been happy with Garnier in the past; but beware... If you're like me & not fluent in other languages. Mine turned up with instructions in another language, despite the listing showing the box in English. I'm going to have to see if there are any online, or if a friend can help me translate!

Brilliant, first ever time using a box dye, I’ve always gone to a salon and had bleach foils, felt like a wanted a break and a change. This has turned out perfect and very close to my natural colour. Also has left my hair feeling very healthy and soft
