The Dyson Airstrait Straightener is down to $399.99 for Black Friday, its lowest price yet, according to price trackers. Normally $549.99, this $150 discount makes the premium hair tool a little more accessible, especially if you’ve been waiting for a deal to try it.

What sets the Airstrait apart is its unique approach to styling—there are no hot plates, here. Instead, it uses precisely controlled airflow to straighten damp or dry hair without relying on direct heat. This helps minimize heat damage while still delivering a sleek finish, which could be a big deal if you regularly style your hair and want to keep it healthy long-term.

Unlike traditional flat irons, the Airstrait is designed to dry and straighten your hair in one step. For people with thick or frizzy hair, that’s a big time saver. You clamp it closed like a regular straightener, but what’s happening inside is more like a mini hair dryer. You get two modes (wet and dry) and several airflow and heat settings depending on your hair type and needs. And because it doesn’t clamp your hair between burning hot plates, it’s gentler over time. The cord is also salon-length, which makes it easier to maneuver around your head without yanking or twisting.

Still, this isn’t a budget buy, even with the discount. It’s also bulkier and heavier than a typical flat iron, and it’s not the best choice for precise styles such as curls or flips. It also takes some getting used to. But for those who want a fast and efficient way to go from damp to done with less damage, the Airstrait holds up. If you already use a blow dryer and brush daily, this could replace both. And with this being the lowest price tracked so far, it’s a good time to grab it.

How long do Black Friday deals really last?

Black Friday sales officially begin Friday, November 28, 2025, and run throughout “Cyber Week,” the five-day period that runs from Thanksgiving through Cyber Monday, December 1, 2025. But Black Friday and Cyber Monday dates have expanded as retailers compete for customers. You can get the same Black Friday sales early, and we expect sales to wind down by December 3, 2025. 

Does Apple do Black Friday?

Yes, Apple participates in Black Friday, though you may want to compare their sales with other retailers like Best Buy and Walmart. Apple is offering an exclusive $250 gift card for eligible purchases, but so far, the best Black Friday sale on an Apple product is the M4 MacBook on sale for cheaper than ever.

Does Amazon have Black Friday deals?

Yes, Amazon has Black Friday sales, but prices aren’t always what they seem. Use a price tracker to make sure you’re getting the best deal, or refer to guides like our live blog that use price trackers for you. And if you have an Amazon Prime membership, make the most of it.
