I did not get my eyebrows shaped until I was in my 50s. I have very light eyebrows and fairly sparse, so it never was a priority. One day I was at the beauty salon, and I decided to take the plunge. I would finally have my eyebrows waxed. As I went through the rather painful ordeal for the first time, I held onto the chair, while screaming on the inside. When the deed was finally done, I jumped out of the chair, and announced to everyone in the shop, "Today I'm a woman!" (The whole place erupted into laughter.)
These days I have decided that with my rather light and thin eyebrows, I'd just as soon tweeze them now and then, as to spend $10.00 to $14.00 dollars for that kind of torture. The tweezers I purchased are Revlon's Slant Tip Expert Tweezers. They are a purple shade, instead of the usual silver. They are stainless steel and easy to grip, and hold onto. For $1.00 Revlon will repair, sharpen or replace them, though in my opinion, it would be easier just to buy another pair, as they are so inexpensive.
I still scream inside (and sometimes outside) when I shape my brows, but at least now I can suffer privately.
