Préférence Preference Permanent Hair Colour - 3.0 Dark Brown

I second the opinion of Iza. I'm a natural blonde a bit lighter than the shade as the lightest "pre" image on the back of the box. It turned my hair the darkest blonde "pre" shade almost exactly. I have never used L'Oreal's hair colourant before and I never will again. I bought one of the lighter shades thinking it would resolve it but it only took some of the redness away. I am so selfconscious at work and really angry with myself. I'll be switching back to my usual brand - nice n' easy - which at least gives results that match the box!
Very, very unhappy. Would strongly advise you to reconsider if you're thinking about giving this a go.

I have used the Brasilia colour for like probably 20 years and am very sad that with the recent renaming to dark brown and obvious formula change, I have found the colour is not as dark and the formula is now very foamy and runny it drips all over the place, makes it difficult to apply to the exact area you want it to go as easily as it once was, especially if you have more than one colour in your hair. I also find the greys aren't covered as long. Unfortunately and regrettably due to these reasons, I'm moving to another brand.

I have been using L'OREAL Preference Oslo for many years and have been very happy with the results. I have strong hair and find I need to leave it on longer to now cover my grey hairs which I did not have when I started using it! Sadly, I am finding it more and more difficult to obtain as the shops where I used to buy it don't seem to stock Oslo. I have tried Excellence number 9 but it resulted in totally the wrong shade. Does this mean you are not manufacturing this product? Please could you give me feed back. If this is the case I will be a very disappointing customer!

I have naturally dark blonde hair and use this colour to lighten it and it gives me a lovely natural light blonde look, my only problem is the grey coverage only lasts for around 3 to 4 weeks and then the grey is noticable however this seems to happen with the other hair dye brands I have also tried that are available on the market, I would definately recommend this product to anyone who is already a natural blonde that wants to go a few shades lighter, its easy to use and there is enough solution to cover my long hair and leaves it feeling nice and soft and smooth.

i have used loreal for a long time now but this new dye with colour extender seems to have changed the product. after applying dye and rinsing out my hair felt matted and stripped of all oils etc. the conditioner made a differnce but my hair now feels like straw and has no shine. i will not be using this product again. i have also been disappointed with the root touch up. loreal what ever your doing please go back to the old dye it was lovely and worked well............all you have done now is ruin the product!

I love this colour, it was perfect for me. I was going from dyeing my hair blonde for years, in 2 stages, back to a more natural red, and this was used 2 weeks after I used California as my stage 1 move.

My hair turned out exactly the colour I expected, no, correction.... in fact it was 100% nicer than expected, richer and not at all too dark - which was my only real worry.

My hair is now a beautiful cross between chestnut and red and it is gorgeous, glossy and really interesting.

The condition is top class too. I will keep this colour from now on. All I need is for you not to discontinue.

I would love to see more natural reds in ranges - this fab colour is often overlooked in ranges and I think its because people are scared of how reds turn out - but seriously, don't be with this range, they are natural and fab!

Been searching for years but have finally found a colour I adore and have stuck with it - really hope you never stop making Oslo hair dye L'oreal! I cannot get over and neither can my hairdresser (who has swapped to this exact colour after seeing it), how natural it looks (my partner also loves it). Not a yellow colour whatsoever - thank you very much. I would give 10 out of 10 if I could x

Terrible effect. My hair before dying were blonde, just different shade than that on a box. So I used this hair dye, to simply change the shade of my hair, and completely new hair color turned out: brown. Plus, this brown looks terrible, is not even a nice brown. The box simply lied.
