Hmmm, nothing! The hairs are going to fall out no matter what you do. So, thank goodness the makeup industry now has a brow application which has little fibers that can be brushed onto the existing eyebrow hairs, filling them in for a fuller look.
Okay, so I wanna get permanent eye brows. Mine are so light you cannot see them. I have to draw them on. Know anyone who has ever had permanent eyebrows and the results? I would think they would fade, much like tattoos.
