The SinglePass Smooth X is our Luxury choice for people with long or thick hair who want fast, polished styling and the flexibility to straighten or curl.

A luxury straightener built for fast, polished styling
The SinglePass Smooth X earns our Luxury pick because the evidence points to a fast, capable tool for larger sections of hair. TechRadar found it particularly effective and quick, with an ergonomic shape that works for both straightening and curling. Its longer plates helped the tester style more hair at once. PureWow likewise found the heat-up time extremely fast and the everyday styling performance strong.
That suits long or thick hair especially well. The same long plates that speed up larger sections also make the tool useful when you want to curl or wave the ends. Buyers reinforce that picture: several describe even heat, smooth gliding and sleek results, while one stylist specifically praises the extra-long plates.

What to know
- TechRadar says very fine hair may look too flat and lose volume.
- Some buyers report pulling, burning or hair damage, and others say the tool stopped working after several months; these are reported by a minority, but they matter when durability and gentle handling are priorities.
- PureWow notes that the tool has no precise digital temperature display and no rest stand or heat mat, and that some hair types may need more than one pass for a fully frizz-free finish.
