Has anyone bought a hair system with too dense a hairline and then made it graduated density themselves? I wonder if it's easy to do. Obviously it's better to buy a system with a proper graduated density hairline, but is it possible to DIY it too? I know how to thin out the density of hair systems using a thinning scissors, but I've never done it on a hairline. I'm actually thinking of plucking the hairline on my current system to thin about the hairline a bit, as I don't think it's graduated enough.
