Very convinient cosmetic, you could put this drop in to shampoo, condicionier, mask or etc

I've used this a few times now, did absolutely nothing, no matter how many drops I saw no change to my colour. went back to my loreal professional shampoo. disappointing considering the price point.

It's such a clever idea being able to add to your own shampoo/conditioner etc, I use sulphate free and so hard to get a toning product that is so that in itself is ingenious! I must admit in using this every time I wash my hair in both shampoo and conditioner and I can honestly say I'm seeing a difference, I have dyed brown hair that's been fading out since October, it is naturally mousey brown but the toner is bringing out my blonde highlights that were more ginger before hand so I'm very happy!

I have natural fair blonde hair, which depending on what products I use can lean to  ash blonde/a light strawberry blonde/ golden blonde, also seasonally in summer and how hard the water is..... since moving house, I have hard water, I’ve noticed the warm tones becoming more strong and really unbalancing my complexion, I’ve been searching for something that I can mix with products that doesn’t contain silicone, THESE DROPS ARE FAB they actually work to counteract the orange and gold tones in my hair making it much cooler and brings out natural highlights.  I’ve used them mixed in shampoo, conditioner and serum.  I also use the pureology cure blonde once a week. I have had comments on whether I’ve lightened my hair.  Would recommend highly.
