Hey, you guys are probably missing something: When inside the caves, you can destroy the red courtains and the other similar type of courtain, but black, that drops more fenris hair and the red stuff.

I just made 1 cave until now and got 40 hair

No I didn't miss that. In my very first cave I found out about that. But the thing is, the Mobs drop very few of those hairs... only if you are super lucky and get that one room with two two-part "carpets" hanging down the wall you have a jackpot.
Those consists of 2 parts, the top is just 1 hair.... the bottom can have up to 5 strands hanging there which you can pick by pressing "E".
