i have a couple of brushes that still turn the water dark blue - a 129 and a 109 brush. no clue why because i have had them years. weirdly that 129 is more scratchy than my other 129. i don't think it should happen but it certaintly hasn't caused me many issues.I find mine really scratchy which puts me off using it, leaving it sitting unloved. I use conditioner every few times I deep clean and the rest of the time Mac brush cleanser. My brush still leaks dye when I wash it, as in the shampoo turns dark blue, is it normal after all this time?
