Amazon shoppers are heaping praise on a buy said to provide 'instant' relief from migraines and headaches. The £20 face mask, which is said to work faster than medicine, uses a natural pain relief method.

The ONLYCARE Migraine Relief Cap costs £19.95 on Amazon, with four different colours to choose from. The migraine headache relief hat applies moderate pressure to your head.
