Olia permanent colouring and bleaching 4.0 Castano Scuro

I used to use herbal hair dyes, but once I found out Garnier no longer tests on animals I was happy to give this one ago. And I am in love! It is so gentle on my scalp, any other hair dyes I previously used would leave my scalp itchy. My hair also feels great afterwards, and not bone dry like after other dyes. I use the rose gold hair colour on top of my dyed ginger hair. This doesn't make a big colour difference, BUT it does give the colour much more vibrance and gives it a coppery sheen that I am in love with! There also doesn't seem to be any unnecessary plastic in the box, which I am fond of! The only thing to note is that the colour does take a while to develop, so it's worth just shaking the bottle a bit longer until the colour fully develops. Also I definitely need two boxes for longer hair!

I used this after i bleached my hair midlengths to ends to get a gradient effect. My roots were dark to mid brown (not dyed). On the length it took to a very pretty champagne orange colour, turning it pink on the ends. I did a second covering 2/3 weeks to do my whole head and it lifted 2-3 shades of my natural colour to a gold brown and now it fades much more neatly and blends really well. The dye is very easy to use and does not smell bad. The fact that you can just apply with your hands, rub it through and have it not spot is great. This is a great colour that delivers what it says as long as you take the time to do research and make any changes gradually.

Really strange. I used to use this colour religiously 4/5 years ago and decided I wanted to use it again. There was basically no colour at all in the dye, it was almost like it was all developer. Even when washing out there wasn’t any colour at all in the water. Very confusing and disappointed especially having used this colour so much in the past and loving it.

First thought was how nice it smells. Most other colouring products smell horrible & I always give my hair a quick gentle wash with shampoo afterwards so I dont get wafts of ammonia etc. However, my hair felt dreadfully greasy & washed it anyway which was probably a mistake. The colour seemed to wash out somewhat & hadnt taken as well as it should. I will try it again in a few weeks as my husband & friends like what is, for me, a very different look. Normally I can divide the dye into two parts because my hair is short but couldn't with these bottles so felt it was not such good value. Hair does feel shiny & soft so will revisit review after the next use. It did cover all grey/white hairs.

I adore this colour! It isn’t the longest lasting but I’ve been using it a couple of months now and my hair is bleached underneath so it is slowly staying longer. Really nice peach tones which I love. Easy to apply. One of the bottles is huge with very little content which seems pointless. But it’s lovely product. Not damaging on hair at all.

Good products, good price, easy to use and long lasting

Well it went on lovely! However I have very light blonde hair.... fancied a change and it turned it pink!!! Not peach at all! Lasted one week and now it has a Tiny hint of the pinky colour left. It’s very weird. Now it might be my hair type, but usually when colouring my hair it holds on for it for dear life. This lasted a day! Which frankly is useless. Clearly I can’t get my money back but I wish I could. Won’t be buying this brand again! Shame because it made my hair feel great and smelt good too!

I have strawberry blonde hair and this gives a lovely peach tone Dont expect it to Lighten your hair though if it’s dark you need a lighter for that
