I cannot say enough good things about this product! It's the first one I've encountered where it lived up to it's advertisement!
I paid $12.99 plus tax for it, which is actually a steal considering how insanely good this hair dye is! It left my hair incredibly soft and healthy. There was no need to use the moisture shampoo's or conditioners as I usually have to do when using other hair dyes.

From now on I will be purchasing Olia when I get bored with my hair colour and need a change!

I have grey hair scince I was 15. This is the FIRST hair color that actually covers my grey hair perfectly! Smells great, not harsh on hair. Leaves my hair feeling soft. Only thing i don't like is the shape of the bottle, which i find hard to handle.

Garnier Olia is by far the best hair colour product I've ever used. Comparable to professional salon products. Colour looked natural. Didn't dry my hair out. No strong chemical smell. Will definitely use again!

This product delivers what it promises. It does not have bad ammonia scent and the color was effectively got into hair. Good Product. I just wished that there were more color choices.

I received a box of the new Garnier Olia hair dye from a friend, and I have to say that I really, really liked it! I was quite happily surprised by the colour, effectiveness and most astonishingly the nice smell!

The process was just like other out-of-the-box hair dye processes, except that I found this one asked you to leave the dye on for a little bit longer and after you left it for the recommended amount of time, you were supposed to rub your hair before washing it out. You could definitely feel that this product was much oiler than others (it is oil-based after all) when you were working it through.

I'll admit that I was curious about the non-ammonia smell that I held the bottle right up to my nose and took a sniff (I know, I know, my chemistry teacher from high school would be so appalled!) - and nada! The smell was actually kind of nice and not at all chemical-y.

I used the Deep Violet dye, and have to say that I've never received so many compliments. It came out a bit darker than the box showed (though I have dark hair to begin with so I wasn't too surprised), and I found that the colour had a lot of dimension to it. It also looked super shiny and my hair felt nice and soft afterwards.

I've been dying my hair for years (both in salon and at home) and I can say that I've never used anything twice. Garnier Olia's Deep Violet colour will change that as I'll definitely use it again.
