I think the problem isn't understanding of conditional expressions, it's
that '#' normally starts a comment, so you have to quote it.

The "trick" is to quote ONLY the '#' character and not the rest of the
pattern. Hence Hannu's solution is the most concise, but these work:
[[ $YOURSTRING == '#'* ]]
[[ $YOURSTRING == "#"* ]]
String concatenation in shell language is by simple juxtaposition, no
operator required.
This works, too, by forcing the '#' to be treated as part of a pattern:
[[ $YOURSTRING == (#)* ]]
