Mainly because - since most the device is constructed from high-impact plastic - it's highly unlikely that a person could be electrocuted (apart from pulling the wires out of the device). The circuit will be protected by a fuse - either in the plug - or at the distribution board.

Why does a hairdryer not need a cable with an earth wire?
Hairdryers often have a double-insulated design, which means they have an extra layer of insulation to protect against electric shocks. This eliminates the need for an earth wire in the cable because the double insulation provides adequate protection against electric leakage.
