My eyebrows are thin and have been for about 5 years. Never really overplucked or waxed, they simply became quite wispy.
I use an eyebrow pencil, subtly. But by the end of the working day, it's faded and I have to reapply. I'm too skint and too fearful for microblading, but I'd love to find a pencil that actually stays especially when donning my winter bobble hat.
