Entanglement can occur even if both paricles are spin up or both are spin down. It just requires that if you measure one of the particles, the state of the other particle changes. Another equivalent way of thinking about it is that two particles are entangled if they are not "seperable" i.e. that you cannot write down their state as a tensor product state $|a\rangle \otimes |b\rangle$. | |
