I’m 30 and I know a mature hairline ideally matures around 30 and hairlines can be asymmetrical. My question is can one side of your hairline (top corner not the temples) remain juvenile while the other side is a norwood 3. Have you seen or dealt with cases like this? One side of my hairline is still juvenile while the other has crept up to a norwood 3.
If you know that hairlines can be asymmetrical, then I think you just answered your question. The issue is whether you’re happy with that hairline or not. If you’re not OK with it, you can have surgery to correct it. Otherwise, you can accept the asymmetrical hairline. Or the other side of your hairline may even itself out over time.
