I have a bleached panel in my hair that I'm currently dying turquoise at the salon and have found this product is great for when the salon colour is starting to fade out and become a bit patchy. It gives me the option of refreshing my colour but making it look like this was the colour I intended to go rather than just looking like I have a faded patchy panel I couldn't be bothered touching up.
I would prefer it came in a mouse or paste as the spray bottle becomes rather messy. Read that as I have ended up with it on my bathroom wallpaper. But to be fair, that's my own fault.
I can't speak for what it would turn out on natural blonde hair but it works well on bleached blondes.
I appreciate it's lower price point and right now I'm all about that.
For the money you pay I've been more than happy with this product
