Olia Reviews

I usually colour my hair at home and have used various brands of DIY permanent hair colour. I was intrigued by the product claims of being powered by oils without ammonia so decided to give this a go. For reference I have thick, coarse dark hair with some obvious greys.

The instructions were clear and easy to use. There was no unpleasant smell like some other brands. The mixture was not too drippy and easy to spread especially with a hair colouring brush tool. I had bought two packs in anticipation of having to use more than one due to my long, thick hair but to my surprise I only needed one pack unlike other brands.

While rinsing the colour out, I could tell that the hair colour was still drying despite being powered by oils, however the included conditioner helped to nourish and treat. The end result was ok but not 100% grey coverage, maybe about 70%. I used a light brown shade so this could be an issue with shade selection. I've since washed my hair a few times and the colour hasn't faded.

Overall I think this is quite good, I appreciate the generous amount of product but it may not give 100% grey coverage, and it didn't leave my hair in any better condition compared to other products.

Was excited because of the natural oils for my hair, but several times was disappointed that the colour didn’t cover or stuck to the grey hair shafts as well as other dyes.
For the extra money for this product you expect it to work perfectly every time.
There are better value for money products than this one.

Thought I would give this a try after using a gentler, oil based dye from another brand with no success! Unfortunately I had a similar result with this brand. I always use block/base colours in brunette shades.
Whilst initial coverage is good, it doesn’t last as long as I’d like for a permanent hair dye. The consistency of the dye after mixing is also quite thin and runny which made application more difficult. This is a shame because due to the fact there is no ammonia, there were no harsh/strong ammonia smells during the application and developing process, instead a pleasant light, floral smell. As this dye uses natural botanical oils instead of ammonia, I did notice the condition of my hair after colouring was a lot softer and shinier however this only lasted a couple of weeks. Unfortunately though, the colour did not take to my hair very well and started to fade by week two. I could tell this by the appearance of a reddish tint through my hair. Perhaps oil based hair dyes are not suited well to my hair.

I've noticed a few greys appearing, so i've started to use permanent hair dye. Stumbled across Garnier Olia at my local shops so gave it a go. Tried dark brown 5.0, which is close to my natural colour. I have thick long hair, and surprisingly one box gave me great coverage. It's easy to combine the colourant and developer, then apply all over. I waited the 30 min as recommended and rinsed out. After using the conditioner and blow drying, i'm rapt with the results. My hair is definitely softer, colour is even throughout. I got the colour i was after, and it was an easy process to do at home. Will definitely use again. I found the smell didn't have a super strong chemical smell like some of the other products on the market, which is a bonus.

This is a great home dye that works well in my hair. I have fine hair but a lot of strands, it is wavy.

I found the dye process easy but was a bit disappointed with the coverage of my few greys. The dye smell is okay and the conditioner was pleasant. I also appreciated that the gloves for dyeing were black, it is the little things!

I was a bit surprised after dying that my hair felt quite crispy and I needed to straighten it to get it soft again.

I've used GARNER Nutrisse for many years dying my hair blonde and never had a problem with it, then it was discontinued,

I'd tried GARNIER Olia 9.0 Light Blonde a few times and it always leaves my roots orange no matter how long the dye has been left on my hair and toner won't correct it.

Wont be ever using GARNER again.

The only good thing about this product is the smell

This hair colour doesn't have a strong smell, the smell is actually really pleasant - it has a nice floral fragrance

Normal home colourants normally burn my eyes and nose when I mix the colorant and creme but this one had none of those effects on me at all

My hair is naturally very dark brown black and us currently balyaged an ash blonde, so I used the blonde colour and it worked and coloured my natural roots a lot of shades lighter, the roots are now a dark orange (I will need to tone the orange colour out) but my balyage is now a few shades lighter blonde

I followed the instructions and left it on my roots for 20 minutes and then my existing coloured hair for another 10-15 minutes and it resulted in a nice even coverage, I was able to use one bottle for all of my hair with lots left over to redo my roots again (i have super thin hair a bit under my shoulder)

It was really easy to mix, the developer bottle is really cute and I really liked the even result so I will definitely be buying this brand again when my roots grow out

I am surprised that it could lighten my hair that much given that there is no ammonia / strong smell

Easy to mix together, although I found it tricky to get the developer out of the main tube, as it very thick and the tube is thick plastic so its hard to squeeze the end nearest the nozzle meaning you can't really get the last bits out - had to put the lid back on and 'flick' it down to the nozzle a few times. This was a bonus later though, as it meant the actual dye was thick as well.

This was the best smelling home hair dye I have used for a while, as there is no ammonia so it doesn't make your eyes water. The consistency is rather thick, so it doesn't dribble down over your skin, so made clean up easier - just one little bit behind one ear and my hairline at the front where I got carried away making sure all hair was covered. It was easy to apply, but being slightly less liquid than other brands meant it had to be worked in through the hair a little more - a small pay off for not being coloured everywhere by runny dye though!

The smell was the best thing about this, as there was no smell at all I could detect. This meant no watering eyes, no horrid smell etc, it also didn't make my scalp itch at all, which can be really annoying with dying your hair I find.

The worst thing was its sort of wrecked my hair unfortunately, and the colour is extremely flat - very very 'home dye job' dye.

I wouldn't recommend this, due to the condition it has left my hair in - if feels thick and coarse, whereas my hair is extremely fine - at least it has given it body haha! - and just feels 'dead', and *a LOT* of hair snapped off and came out when I washed out of the dye (I followed the instructions exactly). But also the colour is so flat - its come out a lot darker than I thought it would, I used the red dye colour and it is a dark burgundy colour on me - usually quite pretty, but I prefer something brighter personally - probably better for people who have to have a more 'normal' hair colour than me. Its just that its so flat though - very much all one shade and tone, no movement in it at all, it definitely looks like a box dye job.

I don't have any greys to cover so can't comment on that.

This was my first time being selected for a Trial Team, and I was super excited to learn that it was for Garnier Olia Permanent Home Hair Colour. Usually I dye my hair dark brown, but I thought I would do something different for this one, so I chose Deep Violet which looked to be an almost black with purple on the box.

This hair dye is very simple to use and it comes with everything you need right in the box. The box even has a perforated section that you pop out, then use the hole in the box to stand the bottle up to prevent spillage.

This dye is applied to dry hair and you mix the developer cream and the colourant in the bottle supplied, just the same as most home hair dyes. Then you apply in sections, starting at the roots until the hair is saturated. This product smelled so nice and there was none of that horrible chemical smell that most of them have. I didn't need a gas mask or evacuate the whole house due to fumes, it was a very enjoyable experience for the whole family lol.

The hair dye applied super easy and with hardly any mess or fuss. Even the dye left around my hairline was easy to remove with almost no staining of the skin - you gotta be happy with that! As per usual, you wait about 30 mins before washing out the dye. The dye washed out really easy and left no clumps of colour on my scalp. The silk and shine multi-application conditioner left my hair feeling so silky and smooth and smelling amazing!

This product delivered great colour and shine and completely covered all of my greys. My hair looks gorgeous and purple, i was hoping for an almost black colour, whereas this is a tad lighter and more purple - that is totally a colour preference and nothing to do with the product itself. I will definitely use this hair dye in the future and recommend it to friends and family as it delivers great results while still looking after your hair and scalp.

10/10 Garnier Olia!!
