Superior Lore-Friendly Hair HD textures

Splash of Rain
Better Dynamic Snow
HQ Snow Textures
Expanded Skyrim Weather
Supreme Storms
Towns and Villages Enhanced
Trees HD
Lush Grass
Pure Waters
HD Plants + Herbs
Pure Weather
Enhanced Distant Terrain

I'm sure they're others which are better but I've used these for forever now.
