Been using this from my hairdresser the last 3 years been buying from him as stocks it the 375ml and the 1LT but was cheaper on line. Stopped using shampoo from Supermarkets few years ago as find not good at all. I colour and cut my hair every 8-9 weeks and its the Goldwell colour he uses just lasts so long to
But saw you had the 1LT and you don't need much at all of this shampoo maybe 5c-10c piece and goes a long long way. I've just gone onto my 3rd bottles had brought extra when I went to South Africa and year before that to Cook Islands from the swimming daily incase need to wash hair every day and just started the the 375ml I have.
1Lt put away for now. Just love this Shampoo as I only was my hair once a week as by hairdresser as have done as too many times strips colour away unless an occasion on with COVID-19 at moment
