Please could you advise what I should do regarding my eyebrows. I'm blonde so they are fair and they are quite thin, especially on the ends, partly down to over plucking when younger. I would love for them to be a bit more defined and shaped, and perhaps a bit darker. I have threaded in the past and use an eyebrow pencil each day. I know there are different treatments out there though. What would you recommend please? (I don't want anything as drastic as tattooing). Thanks :-)
