Hi just wondering if anyone can recommend a purple shampoo that's not too drying. I had my hair coloured after lockdown and it has a very yellowy tone I'm not used too. I would like to try a purple / violet shampoo to try and tone it down a bit and maintain the blonde but my hair is fine and quite damaged from heat & colouring over the years and most purple shampoo I have tried have dried it out even more. Thanks
