(Concern) M-shaped forehead

I'm worried because my hairline is an M shape. It's slightly uneven and the right side is more M-shaped than the left, so it bothers me. That's why I cut my side hair quite short, but it still doesn't look good when it's windy or tied back in an updo style ㅜㅜ. Also, I feel like the hair volume on the right side is less than on the left. I'm very curious about how to maintain hair volume and correct the M-shaped hairline.
