If this is the shampoo or conditioner(no product picture, so I'm not sure): Brassy blonde to Golden Locks! Even after my hair was coloured and quite frankly... getting brassy orange, this product stripped the carrot tones and revealed the sunshine gold! Tip: leave it in for a bit if your looking for a last min fix to refresh the blonde back! Also try it with the John Frieda lightening spray when blow drying for an extra blonde boost ;)

Great way to extent your color/roots between salon visits!

I dont like this serum. I didnt see any improvements to the brassiness in my hair. It also made my hair very oily and not as soft as other serums.
