Yes, you can always expand or increase the size of the helmet by using some easy method. For making it a little loose, first of all, you have to get a soccer ball and place it inside the helmet. Make sure that the ball is deflated. After putting the ball inside the motorcycle helmet, you have to start inflating the ball. Slowly, it will push the inner parts of the helmet and make it larger. After the ball is tight and ready, you have to leave the helmet like this for about 24 hrs. In these 24 hours, the ball will pressurize the helmet from the inside.
