Neuro by Paul Mitchell Smooth+ 1.75in Ceramic Flat Iron – Dual Voltage & Extra-Wide Plates

Overview

Meet Neuro by Paul Mitchell Smooth+ — a 1.75-inch ceramic flat iron designed for smooth, frizz-free styling with speed and control. Built around extra-wide CeraShine ceramic plates, it glides across long, thick, or curly hair, helping you achieve a polished look in fewer passes and with less effort.

Powered by NeutraHeat technology, heat is distributed evenly across the ion-enhanced plates to minimize hotspots and promote consistent results. A single snag-free pass can yield a sleek, glossy surface, making everyday styling feel efficient and straightforward.

Performance at a glance

• 6 heat settings up to 450°F to match hair type and styling goals
• Pro 450°F setting for professional use only
• Locking switch keeps plates secure when not in use or during travel
• Cool tip provides a safe, comfortable grip during styling

Real-world results can vary by hair type and environment, but you may notice a notable boost in shine and a controlled frizz profile. Neuro notes 150% more shine* and 24-hour frizz control* versus naturally dried hair in third-party testing. The claim about faster styling stems from smoothing and straightening performance relative to the Neuro Style+ 1-inch model. Always follow care instructions and product guidelines.
