A hairdryer is a staple in most people's beauty routines and although it's a must have for many, that doesn't mean they're not expensive. Because of this, you'll probably want to research your perfect one before buying. The Remington Proluxe Ionic Hair Dryer (£37, originally £70) comes with three attachments (including a diffuser) and has three heat settings and two speed settings, making it a great and affordable option thanks to Prime Day.
