The latter Edwardian years was the era of enormous
Cartwheel hats and these hairstyles were necessary to support them.
The bulk was achieved by backcombing and padding. Pads were either a horse-hair roll (called in fun a "rat") or the woman's own hair salvaged from her hairbrush.
At this time when the hat was of such importance, the inconvenience of maintaining a style such as this, had to be tolerated.
To date I have never seen a name for this hairstyle.
A simpler contemporary of this style using no back-combing or padding was known as Side-Swirls.
