I was very scared to use any other products to bleach my hair but with this product I managed to go from dark brown to very light blonde PS: I’m not a hairdresser or hairstylist this mean anybody can do it just read the instructions.

Well! I’m utterly surprised and sooo happy with my outcome, this review is for anybody who wants to use this and DOES have previously bleached hair! I know it says ” not recommended on grey or bleached hair” but I just said stuff it and slapped it on and it’s turned out better than I expected! Got rid of all that yucky yellow tone! And the colour match with my extensions is just on point! I went to pick my kids up from school and all the other moms were complimenting my hair and asking if I just had it done and couldn’t believe I had extensions in as the colour match was that good! I haven’t washed it yet so I don’t know how well it’ll stay but I’ll 1000% be coming back to this produc

5.0 out of 5 stars Amazing! - and used on previously bleached hair !

This colour is beautiful, it is like a rich Dark chocolate but not black which is good as it leaves a natural looking colour and doesnt make your skin look pale. Excellent coverage for gray bits and leaves a brilliant shine. Putting the dye together was a tad fiddly but worth it all the same. I normally use Garnier nutrisse hair dye in darkest brown as it is a few pounds cheaper but this is so much better.

Bought this as read others didn’t have an allergic reaction. A few years ago had a serve allergy to hair dye blisters all over scalp, eyes swollen. Tried other hair dyes with no phd or ammonia and had slight reaction to them. After letting my grey come through but looked like a skunt lol with my grey on top and black hair at bottom I decided to take a cherub this hair dye. Done patch test all ok. Put this dye on and omg I’m so happy NO REACTION at all covered my grey but I only bought a light brown so it’s has tinted my grey but no I know this hair dye is good I’ll buy a darker brown to cover greys properly.

I love this brown! It goes on dark and lightens up after a few washes so don’t be too alarmed if you wanted chocolate brown and ended up with dark black/brown. It’s left my hair looking shiny and natural. Love this hair colour brand!

5.0 out of 5 stars My Go-to brown!

I don’t often leave reviews but wanted to share my mixed feelings about this product. I had bleached my very dark, parlty grey hair recently and the dark bits, as expected, were left orange whilst they grey bits were almost white blonde. I first used a Knight & Wilson colour toner to reduce the orange and it did work, although not as much as I wanted. I could have repeated treatment, especially given how richly conditioning it was, but the smell was off-putting. Very highly and unpleasantly fragranced. So after lots of searching decided to decide the Olia very light blonde given its claims of leaving hair beautifully soft and conditioned. Just what we all want, right? Unfortunately, the colour is perfect so my hair colour is now more evenly balanced, but it feels like straw! Shame that it works well in respect of colour but not in terms of conditioning. Luckily my hair responds well to organic coconut oil, which I just rub through and leave in. I buy it from any supermarket as a food product which is cheaper.

I used to be this dark naturally but someone up there in the planning department decided to have a laugh and start sending me grey in my early twenties, so I’ve had to use dye to keep it up since. (I’ll give up one day, but today is not that day!)

Now, in my mid-thirties I find a lot of permanent dyes don’t take as well to my roots, which just looks rubbish and is super annoying. Even in salons. This, however, takes beautifully! It covers all greys and doesn’t leave that strip of slightly lighter coverage on the roots.

I would highly recommend to anyone who likes a rich glossy natural looking dark brown, especially if, like me, you have issues with coverage.

I used this as a highlight dye. It works well. Smells nice, is easy to use with good instructions. The conditioner lasts a long time and is really nice to use. But… the colour isn’t true to the guide. Mine didn’t go a golden brown, more of a coppery red. Which is fine as I naturally have this tone anyway, but it wasn’t what I was expecting. I would buy this brand again.

The guide colours on the box are way off! The hair dye is bright fuscia when it develops, I thought it would wash out and look paler but it didn’t! I didn’t take a before picture but it was light brown hair with blonde highlights. I’m now half ginger half fuscia- somehow the blonde bits are darker than my routes now. It’s also left my hair feeling really heavy and greasy, I’ve scrubbed it with shampoo about 4 times but it looks like I haven’t washed it on a week, I’m absolutely devastated! I would rather be bald! EDIT- Several washes later I actually LOVE the result, it’s faded into the prettiest shade of pink and no longer feels like there’s build up- I actually would use it again! Editing from 1 star to 4 because it was a rollercoaster!

4.0 out of 5 stars Deep rose. Major regret!

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!
