How Does Dyson’s Liquid Cooling Straightener Work?
Traditional straighteners rely on ceramic or metal plates that heat up and can fluctuate in temperature, leading to hotspots that damage hair. Dyson’s new straightener, part of the Corrale line, uses a unique liquid cooling system. Inside the plates, a coolant circulates through micro-channels, actively drawing heat away from the surface. This allows the plates to maintain a precise, even temperature—up to 365°F—without the spikes that cause breakage.
The result is that you can achieve the same sleek style at a lower heat setting, reducing the thermal stress on each strand. The liquid cooling also ensures that the temperature remains stable even as you glide through thick or coarse sections, preventing the need to pass over the same area multiple times. This technology is a significant leap from older models that rely on passive heat distribution.
Does It Actually Cause Less Hair Damage?
Early tests and user reviews suggest that the liquid cooling system does make a difference. Independent lab tests have shown that hair styled with the Dyson straightener retains more moisture and has fewer split ends compared to traditional straighteners. Users report that their hair feels softer and looks shinier after regular use, with less frizz and breakage.
However, it’s important to note that no heat styling is completely damage-free. The key is that Dyson’s technology minimizes damage by using lower temperatures and consistent heat. If you have fine or fragile hair, you’ll likely notice the most benefit. For thick or coarse hair, you may still need to use a higher setting, but the even heat distribution helps prevent hot spots that often cause damage.
Dyson Straightener vs. Corrale: What’s the Difference?
The new liquid cooling straightener is actually an upgrade to the existing Dyson Corrale. The original Corrale used flexible plates that bend to gather hair, but it didn’t have the liquid cooling feature. The new model incorporates this technology to further protect hair from heat damage.
When comparing the two, the liquid cooling version offers more precise temperature control and is marketed as being gentler on hair. If you already own the original Corrale, you might wonder if it’s worth upgrading. The answer depends on your hair type and styling habits. If you style daily and have noticed damage, the upgrade could be beneficial. But if you’re happy with your current Corrale, the difference may not be dramatic enough to justify the cost.
Price and Value: Is It Worth the Investment?
Dyson’s liquid cooling straightener is priced at $499, which is $100 more than the original Corrale. This places it in the premium tier of hair tools, alongside other high-end straighteners from brands like ghd and T3. But does it justify the price? For many, the answer is yes if you value hair health and are willing to invest in a tool that lasts.
Compared to competitors, the Dyson offers advanced technology, cordless operation (up to 30 minutes), and a sleek design. While cheaper straighteners can achieve similar results in the short term, they often cause more damage over time. If you factor in the cost of hair treatments to repair damage, the Dyson might actually save you money in the long run. However, if you’re on a budget, there are effective alternatives, but they won’t have the same cooling technology.
When and Where Can You Buy It?
The new Dyson straightener is available now on Dyson’s website and at select retailers like Sephora and Ulta. It comes in a variety of colors, including the classic Dyson purple and a new rose gold edition. Given its popularity, it may sell out quickly, so if you’re interested, you might want to act fast.
