Oh dear! It's not often that I find something that I really don't like - as I'm a happy-go-lucky sort; but Garnier Olia was a real disappointment!
I found it to be thin and watery as opposed to oily as the name suggests. I didn't feel that this provided good coverage at all on my hair, with it somehow managing to slip past whole sections I'd applied it to, for no good reason :/
The colour was also a little weak for my liking and the images and chart on the box and for any area that it did cover, it did not cover the greys well, instead coating them and becoming brighter - which to be honest I did think was cool, but that's me. I'm sure someone who's not into crazy hair and fashion, may not be so pleased.
I purchased this whilst off work on maternity leave. As a hairdresser home colouring is a no no but I was desperate!
I've used a couple of box dyes as I believe it's good to try out & see what your clients are using at home. This one looked good as it's ammonia free & the magazine reviews sounded good! Choosing the fiery red, I headed home to get glam. I followed the instructions, only doing a retouch.
It was hard to apply, although no itchy scalp like some other brands.
Result was poor though, the colour was dull compared to my untouched & faded ends! It didn't cover 100% & I'm naturally very light & take colour easily. My hair felt rough, tangled easily & the colour faded within a few washes.
I also found I had to do treatments more often to get condition back (actually had a review product at the time which was excellent timing!)
Tips: I'd recommend using on natural hair & maybe shorter lengths. For anything more then a retouch on thick hair you'd need 2-3 bottles to get good coverage
