I appreciate your New Years greetings, smoothlover.
Just by observation, you may see that hair on one side of the body doesn’t necessarily mirror hair on the opposite side of the body. If you draw an imaginary line down the middle of your body starting at your forehead, you may notice that one eyebrow grows more hair on one side and in a different pattern than the other eyebrow. Going down a little further, one areola has more hair than the other areola and the pattern of growth is different there, too. Since blood flow helps determine hair growth, that can perhaps explain why some people may have more hair on one side of their body than the other.
Eyebrow hair is different than scalp hair or hair on ones legs, or hair on ones arms. The growth of eyebrow hair depends on the blood supply to the frontal bone area of your forehead. In some cases there is not a sufficient blood supply to keep nourishing and replenishing hair growth here. If a person with diminished blood flow to the eyebrow area repeatedly tweezes this area, these hairs may never grow back. Also,scar tissue sometimes develops and the follicles of eyebrow hairs, from repeated tweezing may cause those hairs to never return. Any hair that returns after plucking your eyebrows obviously has a good blood supply,but that may not always be the case as time goes on.
I would never advise anyone to pluck, wax or sugar anything on their face. Eyebrows are the exception because they are a different animal altogether. You just have to make sure that when you pluck or wax that your eyebrows have a shape that is flattering to your face. If you change your mind in the future and decide to let your eyebrows grow out and re-shape them, you may not have all the follicles functioning as you did when you were younger.
If you have hair that bothers you on your upper cheeks, would you consider permanent removal with electrolysis? Long run, your better off.
