I have tried Casting Creme Gloss for the first time, and although the colour is good the process of mixing the tube and bottle proved difficult. I have coloured my hair for the past 15 years and never experienced any difficulty with any other product before. The tube wouldn’t squeeze in the bottle hence the dye all over my sleeve and bathroom cupboard. I found it too much like hard work. Though, the result of the colour when final done is very good. Please can you make this process simpler. Try using plastic bottles for both liquids instead of tube. Thanks youa9736
