I'm about to make an appointment to tint my brows and lashes - for only $8 I have no reason not to, when I spend more than that on a light brown mascara and brow filler. have blonde lashes and brows, and I like to look naturally made up so lightly filling my brows and a quick sweep of mascara seem to help. Does anyone have experience with this? I know it's been OK'd by YLF, but I'm wondering what happens and how long the results might last. Any input would be great!
