For some context here, I colour my hair with a semi-permanent colour, not a permanent one.
My colour would normally begin to fade to its normal coppery tone after about 4 weeks, but after using this it seems to have lasted a little longer than usual, but nowhere near as long as the loreal professionnel version of this does. For the price point though, it's probably worth it.
The smell is nice, but strong enough that a colleague mentioned smelling it in the lift when I exited.
Did leave my hair feeling quite soft and manageable which was impressive. After so much colouring, my hair is usually a matted mess after a single gust of wind but not with this shampoo and conditioner.
I was really looking forward to this trial because I typically dye my hair more...unusual colours. At the moment I have been rocking the purple but I had a slight dye mishap leaving me with green hair which I have to slowly cut out due to it being permanent which means I couldn't test this shampoo as well as I wanted to in terms of how long the colour lasted.
In saying that I do find that my green hair does seem to be much more vibrant from using this shampoo. It has a pleasant smell and while my hair was a bit knotty after washing it out my hair tends to always be like that if I don't use a conditioner.
I think I will put it aside and use it retrial it again when I can redye my hair just to test it properly but overall I do like it
