By no means am I a makeup artist, but I needed a solution to my sparse eyebrows. When I was 22, I had cancer and chemotherapy. Due to the treatment, my hair fell out. While I am super happy that all of the hair on my head came back, I was disappointed that my eyebrows did not. I do still have some eyebrows towards the center of my face, but on the outside parts, it is much less full. To remedy this, I have found 2 solutions that don't make me look like I have painted on eyebrows and I always get compliments on them.
1. I use a simple L'Oreal eyeshadow powder and an angled paint brush I got from a local art store. The brush is soft and thin, but not so narrow that I cannot fill my eyebrows on a pass or two.
2. During the summer or when I plan on swimming, I use Makeup Forever Aquabrow. This stuff will honestly stay on your face all day as long as you don't rub it. I have gone swimming in the ocean and then the pool for about 8+ hours and when I was done, it was still on my face. I use a TINY amount so it is not too dark and trace the top of my eyebrow before lightly filling the rest. My brush of choice here is a very thin angled brush from Sephora. I believe it was about $22.
Well, you can buy entire false eyebrows with hairs on them, just as you can buy false eyelashes. I believe they usually are based on a lace fabric similar to that on a front lace wig. Many wig dealers sell them. I've considered trying a pair sometime since my brows are getting a bit on the sparse side, too.
I hear you; I am totally jealous of women with full, perfectly shaped eyebrows.
