I remember standing in my bathroom mirror last spring, staring at my boring shoulder-length hair.
My stylist had been playing it safe for years, and honestly, I was tired of blending in.
That's when I stumbled across undercut bobs on Instagram, and everything changed.
The contrast between edgy shaved sections and soft, flowing bob lengths felt like the perfect rebellion.
If you've been craving something bold but still wearable, these undercut bob styles might be exactly what you need.
