But some things have changed for the Emmy-winning star, including her hair. Yes, Hargitay's Olivia Benson has been put through the wringer over the years—sometimes by perps, other times by haircuts.
Throughout her two-plus decades playing Benson, Hargitay has rocked many hairdos (and only one real hair don't—she's said her season three haircut almost got her fired).
