Deer hair is course and tubular.
There is an extremely fine under fur but the hair is too course to allow it to comb out and there isn't much of it. It is kind of kinky if there was an easy way to get it separated I bet it would hold together even though it is short.
The hair is also very hard on clippers so shearing probably isn't a good option.
