Doesn't clean very well but leaves a purple stain, as it should. Smells nice too

The best to brighten blonde hair. Recommended

I'm impressed by how soft and smooth my hair is. Smells delicious, too. Haven't really left it on long enough to test just how much it knocks out the yellow tones, but it did seem to make a subtle difference, despite my not having time to really let it do its work. Overall, made my over-processed hair feel a lot better, instantly!

Recommended by my hairdresser during lockdown to assist In camouflaging the grey roots of my highlights hair.  Happy to say it works but you do need to follow up with the label m cool blond conditioner due to drying effect of the shampoo 

Not being able to go to hairdressers I wondered what to do about my roots... I have light blonde hair but greying roots.... top and sides. I tried this shampoo, and although it says Cool Blond, you do turn out greyish… but its fabulous!! Using the shampoo without the conditioner is a lesser grey look, so I would suggest trying this first... but it does wash out quickly if you don't like it, so no harm done. But with the conditioner too it intensifies. The product is amazing, but wear gloves whilst applying. The smell is gorgeous and my longish hair has never looked so silky.
