The 45mm Barrel Is Having a Moment — Here’s Why Australians & Brits Are Obsessed
Tight ringlets are out. Bone-straight blowouts are fading. What’s taking over right now — from Sydney to London — is softer, more lived-in hair: relaxed curls, voluminous waves, and that effortless “I woke up like this” finish. The tool making it happen? A 45mm thermal brush. Why 45mm Works for Everyone Barrel size determines curl shape. At 45mm, you’re in the sweet spot: large enough for soft, voluminous movement, defined enough for real shape and hold. It works on bobs and long layers, fine hair that needs lift, and thick hair that needs control. In Australia, the look is coastal and bouncy — lifted roots, natural movement, humidity-resistant hold. In the UK, it’s undone elegance — face-framing flips and soft waves that go from office to evening. Both markets want the same thing: one tool, multiple looks, no heat damage. 4 Looks You Can Create Lifted Roots + Relaxed Body — Roll inward at mid-lengths, focus heat at the root. Voluminous, bouncy, effortless. Face-Framing Curls — Sweep sections around the face outward for a soft, flattering frame. The UK’s go-to for “effortless chic.” Elegant Outward Flips — Roll ends outward as you brush through. Polished, classic, done in minutes. Silky Sleek Blowout — Brush straight through root to tip. Infrared heat smooths the cuticle as you go — glossy, frizz-free, no flat iron needed. Built for These Looks The Glamup SoftWave™ Infrared Styling Brush is designed around the 45mm XL barrel. Its 135mm extended length covers more hair per pass — less repetition, less heat exposure. Dual Infrared Technology (850nm for hold, 620nm for cuticle smoothing) works with your hair structure, not against it. Smart NTC Control ensures even 360° heat with no hot spots. The result: salon-quality curls at home, with hair that feels healthier after styling — not fried. → Shop the Glamup SoftWave™ — $95

Why I Threw Away My Curling Iron for an Infrared Thermal Brush
If you've ever scrolled Reddit's r/HaircareScience looking for answers, you know the hair tool debate is intense. As someone with fine, flat, and frizzy hair, I'd tried everything — and everything failed me. Curling irons fried my hair like straw. Thermal brushes snagged and pulled. Small barrels gave me stiff "prom curls." Short barrels meant an hour of styling for mediocre results. Then Reddit introduced me to infrared thermal brushes. Here's the unfiltered truth. "Moisture Stripper" — What Reddit Actually Calls Your Curling Iron Reddit's r/HaircareScience has a brutal nickname for traditional curling irons: moisture strippers. Direct metal heat on dry hair doesn't just style — it slowly destroys the cuticle, especially for fine hair. Infrared technology works differently. Instead of scorching the surface, it heats hair from the inside out — locking in moisture rather than evaporating it. The community calls it "protective styling that actually styles." When I switched to the GLAMUP Softwave™, my hair felt softer after heat styling. That had never happened before. The Barrel Size That Changes Everything Reddit has a name for tight, uniform curls from small barrels: "Prom curls." Stiff, dated, aging. What everyone actually wants is "model-off-duty hair" — that loose, bouncy, face-framing wave with natural movement. The community consensus: you need at least 38mm, ideally 45mm. The Softwave™'s 45mm XL barrel delivers exactly that relaxed C-wave. Volume, body, movement — not a tight spiral in sight. Long Hair? Barrel Length Is Your Biggest Problem Reddit long-hair threads are full of this complaint: "By the time I wrap my hair twice, there's no barrel left — and the overlap heats unevenly anyway." The fix the community swears by: extended barrels — nicknamed "time savers for long hair." The Softwave™'s 135mm extended heating zone lets you lay a full wide section in one pass. Styling time genuinely cut in half, with even heat distribution throughout. The Snag Problem Nobody Warns You About The top complaint about regular thermal brushes on Reddit? The teeth pull and rip. Hard plastic bristles that catch on fine hair until you want to cry. What the community looks for: "gentle yet firm tension" — bristles that grip without snagging, gliding through like butter. The Softwave™'s bristle design holds the hair securely enough to lift at the root and lock the curl — without a single snag. For fine hair, this is non-negotiable. Frizz That Actually Stays Gone Reddit's r/Beauty calls infrared brushes the ultimate "2nd-day hair saviour." The combination of infrared heat and ionic output seals the cuticle and neutralises static — giving hair a natural, healthy shine without product buildup. My curls now hold through the day and soften into natural waves by day two. No flyaways. No frizz halo.

Why do my thermal brush curls fall flat?Usually technique: start on 80% dry hair and maintain root tension throughout. What's the best barrel size for natural waves?45mm gives the most natural, voluminous result — anything under 32mm risks looking too tight and dated.
