I have thin and sparse eyebrows and since I have round face, it looks really weird at times. The color of my hair is dark, and the eyebrows are thin and sparse! But, I am getting conscious of looking fake if I use eye shadow. I am in 7th grade and I donât want to mess with my eyebrows anymore! I would really like to get some advice from some beauty and skin expert on what should I do to make my thin and sparse look dark and more defined naturally! I shall be thankful to you for an appropriate advice!
