I went through the same issue when i had blunt bangs like you girly. Wish i could teach you how to trim them beautifully. Maybe one day in the future if we meet i will bring my shears. :)
you hair looks so healthy! I think.. you should should keep the length on one side but get it cut short as fuck on the other. I love kid uneven bangs. If I were closer, I'd totally cut them for you. Once you cut them like I explained, they will grow out really nicely and I think you'd look really nicely then...you would look aweomse with perfectly cut bangs on an angle since your hair seems to be really straight...
Oh, I noticed some points of that do not make much sense. Try to make sense of it. I apologize but I still have this wonderful image in my head of what you can do with your bangs.
And also...I think my hair is so healthy and shiny because I don't really do anything to it....I only blow dry my bangs, and the rest just hangs out. And I only comb it after I get out of the shower (which, if you know me...you know it aint that often, haha)
