Making yourself look presentable is the most important thing to a Viking, as no one wants to enter Valhalla without covering themselves in tattoos and finding that all-important hairstyle! In Assassin's Creed Valhalla, there are plenty of cosmetic items that you can purchase to change the look of your character, your boat, and even your settlement.
Assassin's Creed Valhalla How to Get More Hairstyles
To get more hairstyles in Assassin's Creed: Valhalla, you must continue with the story, and when you have enough resources to build a Trader and a Tattoo Parlor, you can then buy and apply more hairstyles whenever you want. Sadly, you cannot collect hairstyles like tattoo designs; the only way to get them is by playing the game and revisiting the Trader every so often, as you progress the story.
The best thing to do with hairstyles is to wait until you can start building your settlement in England and eventually build a Tattoo Parlor where you can change your tattoos and your hairstyle. Wait a while until you build it, as in all honesty they are a lot more buildings that take higher priority, though if you are raiding and pillaging when exploring England, you'll have plenty of supplies to go around!
Next, build a Trader, as once you have a Trader, you can sell your useless items, but you can also buy Cosmetic items for your boat, settlements, and your character. For character cosmetics, these come in two types, Tattoos, and Hairstyles, so buy the ones you want, then go over to your Tattoo Parlor and try them on!
Then keep checking your own Trader every time you come back to the settlement to upgrade buildings, as with story progression comes more hairstyles that you can purchase! So check back often but not that often, as nothing is more disheartening than wanting a new style and nothing being available.
