You’ll need to ask a friend to do this for you. You can also use your phone to take a photograph of the top of your head.

Don’t hold your phone on an angle. If you can see too much of your face, ears, or the back of your head, take another photo.

The easiest way to do this is to hold your phone flat against the top of your head with both hands and then raise your arms as high as you can.

Take a photo and check that you can clearly see the shape of your head.

Wearing In A Motorcycle Helmet
