There are hairdryers, and then there's the Dyson Supersonic hairdryer. It has a huge cult following, keeps your hair smooth and damage-free, and costs an arm and a leg. That is, until today.

As of Jan. 30, the bestselling Dyson Supersonic hairdryer is on sale at Best Buy for My Best Buy members (a free membership program) for $343.99, or $86 off. That's a 20% savings from its original price of $429.99. You will have to create a free My Best Buy membership account to take advantage of these spectacular savings, but it only takes about a minute. And there are a lot of members-only Best Buy deals that won't be available elsewhere, so we consider that a win.

So why is everybody vying for one of these hairdryers? For starters, the Dyson Supersonic hairdryer measures the air temperature 20 times every second to keep your hair from getting overheated and damaged, which is a must if you style your hair with heat often. (After all, hair protectors can only do so much.) The small but powerful motor cuts down drying time by up to 15 minutes for longer hair, and its placement creates an even balance of weight within the hair dryer for easy gripping.

The Supersonic also comes with magnetic attachments to help you style your hair in any way you like—think a diffuser, a smoother, and a unique-to-Dyson flyaway controller. The Dyson’s settings allow you to adjust speed and heat, and even blast a cold shot to set your hair after drying and styling. As of now, the colors fuschia, silver, copper, and limited edition special vinca blue are part of this deal, so you can choose the hue you love best.
