The Great Iron Delivers Salon-Level Straightening at Home
The hair tool market is crowded. Every season brings another straightener, curler, or multi-styler promising to transform your routine. When the Hershesons Great Iron arrived for testing, the initial reaction was cautious optimism. After two weeks of daily use on wavy, thick, and frizz-prone hair, the results speak clearly. This tool does not just straighten — it redefines what a hair iron can accomplish in a single session.
Fact 1: One-Pass Straightening That Saves Serious Time
The most immediate benefit is speed. With standard straighteners, achieving a sleek look often requires multiple passes over the same section. This causes unnecessary heat exposure and wasted minutes. The Great Iron uses 1.25-inch floating tourmaline titanium plates that glide through hair without dragging or tugging. In testing, a full head of thick, wavy hair was straightened in about ten minutes — a task that typically takes twenty-five to thirty minutes with lesser tools.
The plates sit at a width that feels nimble around the roots and hairline. For those with shorter or medium-length cuts, this size is ideal. The only trade-off appears for those with very dense or extremely long hair. In that case, the plate width may require sectioning into smaller portions, which adds a few extra minutes. Still, the single-pass efficiency compensates for the extra prep work.
The heating system reaches the selected temperature rapidly. Three settings are available: 120°C, 180°C, and 230°C. For the test, 180°C was chosen alongside a heat protectant spray. This temperature proved sufficient to smooth waves and tame frizz without causing any sizzling or burning smell — a common issue with irons that push toward the upper limit of 230°C without offering meaningful control.
Why Temperature Control Matters for Hair Health
Most cheap straighteners offer a single heat setting or a vague dial with no real accuracy. The Great Iron gives you three distinct, reliable temperatures. This is not a gimmick. Fine or damaged hair should never see 230°C. Coarse or curly hair often needs the higher setting to achieve lasting results. Having a middle option at 180°C allows most hair types to find a safe, effective balance. Data from trichology studies indicates that repeated exposure above 210°C can weaken the hair cortex over time. The ability to stay below that threshold while still achieving a sleek finish is a genuine advantage.
Fact 2: Curling Capabilities That Actually Work
Many people struggle to curl hair with standard straighteners. The result is often kinked, ribbon-like curls that look unnatural and stiff. The Great Iron solves this problem with curved edges and a rounded barrel profile. These design elements allow the iron to wrap around sections of hair smoothly, producing soft, loose curls rather than harsh bends.
During the test period, the iron created beachy waves that held for an entire day without product overload. The technique requires a simple rotation of the wrist as you glide down the section — similar to how you would use a traditional curling wand. The difference is that the same tool also straightens, so you are not switching devices mid-routine.
S-Waves and the Sienna Miller Effect
Beyond basic curls, the Great Iron excels at creating S-waves — those piecey, lived-in waves that look effortless. By clamping a section and alternately bending the iron forward and backward along the shaft, you can produce soft zigzag waves that mimic the look of a crimper but with more natural movement. This technique works well for shoulder-length and longer hair and adds texture without volume at the roots, making it suitable for a relaxed weekend aesthetic.
Fact 3: Floating Titanium Plates That Reduce Friction Damage
The plate material and construction matter more than most shoppers realise. The Great Iron uses tourmaline titanium floating plates. Tourmaline is a crystalline mineral that emits negative ions when heated. These ions help to seal the hair cuticle, locking in moisture and reducing static. Titanium provides even heat distribution and rapid recovery time — meaning the iron maintains its set temperature even when you pull it through a thick section.
The floating mechanism allows the plates to pivot slightly as they travel down the hair shaft. This reduces the chance of snagging or pulling, which is a common complaint with rigid, non-floating plates. In testing, the iron moved through the hair smoothly from root to tip, with no audible or tactile resistance. For anyone who has experienced the painful tug of a cheap straightener catching on a tangle, this alone justifies the upgrade.
How to Get the Most Out of Floating Plates
Start with dry, detangled hair. Brush thoroughly before using the iron. Section the hair into manageable parts — about two inches wide for medium density. Glide slowly but steadily, allowing the plates to adjust to the thickness of each section. Do not pause in one spot, as lingering heat can cause spots of overdrying. With practice, the floating plates become almost invisible in use, which is exactly what good engineering should deliver.
Fact 4: Build Quality, Cord Design, and Travel Accessories
A great iron should feel substantial in the hand without being heavy. The Great Iron strikes this balance well. The body has a sleek, matte finish that resists fingerprints. The 360-degree swivel cord is a practical feature that prevents tangling during use. Anyone who has fought with a twisted cord while trying to curl the back of their head will appreciate this detail immediately.

The package includes a protective cover and a soft pouch. The cover fits over the plates while the iron is still warm, though it is safer to let the tool cool completely before storing. The pouch is large enough to accommodate the iron and the cord together, making it suitable for travel or bathroom storage. At £120, the accessory kit feels premium without being excessive — it includes everything necessary to protect the investment.
Comparing to Other Premium Straighteners
Tools in this price bracket from brands like GHD, Dyson, and Cloud Nine typically offer similar plate materials and temperature ranges. The Hershesons Great Iron distinguishes itself through the curved barrel design and the multi-styling capability. While Dyson’s Corrale uses flexing plates and a cordless option, it costs significantly more. The Great Iron provides a comparable experience for about half the price of some competitors, assuming you value the curling functionality alongside straightening.
Fact 5: Versatility Replaces Multiple Tools in Your Routine
The biggest surprise after two weeks of testing was how often the Great Iron replaced other devices. It handles straightening, soft curls, beachy waves, and S-waves. That covers the majority of everyday styles. The only thing it cannot do is add volume at the roots beyond what a good blow-dry provides, but that is true of most irons.
For someone who travels or has limited storage, this versatility is a genuine space-saver. Instead of packing a straightener, a curling wand, and a crimper, one tool covers all three functions. The learning curve is short — within a few uses, the rotation and angle techniques become intuitive. The results look polished without requiring the skill level of a professional stylist.
Who Should Buy the Hershesons Great Iron
This tool suits anyone with wavy or straight hair who wants the flexibility to change styles without buying three separate gadgets. It works well for short to medium hair lengths due to the 1.25-inch plate size. Those with very thick or very long hair may still enjoy it but should expect to work in smaller sections. The temperature range makes it appropriate for fine, normal, and coarse hair types. The build quality suggests it will last for years with proper care, which makes the £120 price feel reasonable over time.
Who Might Want to Skip This One
If you have extremely thick, waist-length hair and you straighten every day in large sections, a wider-plate iron may serve you better. Also, if you prefer tight, corkscrew curls or very defined ringlets, a dedicated curling wand with a smaller barrel might give you more control. But for the vast majority of people seeking a versatile, high-performing hair tool, the Great Iron delivers on its promises.
After two weeks of consistent use, the iron has earned a permanent place in the styling rotation. It heats quickly, glides smoothly, and produces results that look fresh from a salon. The curved edges unlock styling possibilities that most straighteners ignore. For anyone tired of kinked curls and slow straightening sessions, this tool is worth a close look.
