This pair have been wonder products for me. Whilst they are marketed for 'grey, white or platinum blonde' hair, but they fall under the class of 'purple shampoo' or 'toner', cancelling out brassiness in all lightened, highlighted or blonde hair types.

Seeing as I have dark hair that is dyed chocolate brown with half-head caramel blonde highlights, my hair color tends to inevitably diminish into a rather alarming and unflattering shade of brass! Purple shampoo ought to return such colors to their original ash-toned glory!

I used this as it instructs, twice a week, using their Maintenance Shampoo in between. Originally I found that Touch of Silver worked particularly well and the results from each wash were both immediate and apparent however with continuous use and towards the end of their life I did find they became less and less effective - my imagination?

Purple shampoo is notorious for turning very blonde hair, well - purple. As my hair is dark I have never experienced this problem however the blonde among us should be somewhat careful. 

The shampoo is all very difficult to lather, sometimes not lathering at all. You need to use a fairly large amount of it in absolutely soaking wet hair to achieve something that could possibly be called froth, It is also quite drying, most tend to be, but the conditioner does help with that.
