I can't stand Merrill's hairstyle, even when on other NPCs. Almost all of the Merrill mods here on the Nexus also change her face in some way, which I didn't want. Here are five different options to choose from. These are default female elf hairs in the game, no other mods needed.

1 'Morrigan' hair
2 'Wynne' hair
3 Bun hair
4 Elf Pixie hair
5 Short Straight 'emo' hair
