I have a very thick eyebrow and I want to know that how do I know which eyebrow shaping comb is right for shaping my eyebrows? What are the things that I need to know about shaping my eyebrows so that they always look good on my face even I have not done eye brow threading. Shall I but a comb with thin brush? Do you think I should apply any kind of powder or cream before shaping my eye brow?
