Overview
Frizz-prone and dry hair owners get a ceramic straightener with silicone strips in the Bio Ionic OnePass. The strips hold each section taut while heated plates glide from root to tip.
Silicone strips and adjustable heat mean fewer passes over each section, which reduces heat exposure. It runs on the US voltage only, so travel abroad needs care.
Who it's for
Daily straightening and touch-ups on medium to long hair. Travelers heading to countries on a different voltage should choose a dual voltage model.
Pros and cons
- Silicone strips reduce repeat passes
- Digital heat control
- Auto shut-off for safety
- Single voltage only
- Heat-up time not listed
- Item weight not listed
Performance notes
Straightening speed comes from the silicone strips holding tension as the plates slide, so the heat works on a taut section. Digital control lets fine hair run cooler and coarse hair run hotter. The mineral coating is designed to reduce frizz and add shine.
