Tier 3 beards is that they can be super full OR super long but not both. You can have a Tier 3 beard that is very full or curly or a beard that is very long (greater than 14″, typically).
The more curl or fullness a beard has, the more length is “eaten up”. Likewise, hair that is very long will not take and hold curl as effectively. That’s not to say you can’t have a long and full, curly beard. It’s just that there’s an intersection where the length and fullness meet. After that, a choice will need to be made to prioritize length or fullness.
A great way to understand this is to look at the very long Father Christmas beard on the left, and the very curly beard on the right.
Both are Tier 3 beards and were in fact built for the same Santa. While the Father Christmas beard has some curl, it’s concentrated at the ends. That’s because if we curled the entire length, the weight of the long hair would pull the curl loose and the curls would eat up the hair length, making the beard look shorter. If we combed out the curly beard until it was nearly straight, it would be quite a bit longer, because the curls would no longer be making the strands of hair shorter.
