Plain and simple, if you want bangs, cut bangs. Your hair is as unique as your personality, so if you feel the need for fringe, have at it! However, if your goal is to have all one length hair you may take my hair as incentive not to keep cutting those bangs.
My own personal choice is not to have bangs. For one, I look much younger with them and tend to look cute. I’m nearing 40, I have no desire to look “cute”.
Something you might consider is the fact that much shorter hair can very much afford to have bangs without losing volume. Once your hair becomes long, there are few women who can maintain the fullness at length, thus, many grow their bangs out. This is not true for all, but many.
Age and hair type plays a big role as well. As your hair grows, it may reach it’s length potential and thus will be naturally shed. Take the photo of hair below as an example:
You can see on the left that her bangs rest on her legs while the rest is to her knees. Yes, She could cut the rest off to meet her bangs, but this would be rather silly considering she has a large majority of length which is 53″ and only a small section which is tailbone length. She have been growing out her “bangs” since 1996, when they were just above her eyebrows.
I’ve allowed the length of my hair to continue growing while cutting 1/2 to 1″ on occasion to allow my bangs to catch up, as my ultimate goal is to have all one length hair.
