Upgrade Slim2 Bio-Infrared Professional Hair Straightener

Upgrade Slim2 is a professional hair straightener with narrow plates and Bio-Infrared technology to deliver controlled, even styling. A dual Bio-Infrared beam works within the hair fibre, while the integrated ionizing device helps improve smoothness and shine. The titanium plates coated in tourmaline ceramic ensure a smooth glide and protection with every pass. Temperature is adjustable via the digital display from 130°C to 230°C, supported by a dual MCH ceramic heater for consistent heat.

Designed for versatile looks, Slim2’s 25 × 110 mm plates allow you to create straight finishes, wide waves or tight curls with precision. For convenience and professional workflows, the set includes two pairs of CoverUp heat‑resistant sheets and a pouch, and the tool features automatic shut‑off after one hour of inactivity.

How to use

1. Switch on the straightener and select the desired temperature on the digital display (130°C–230°C), choosing lower settings for finer or sensitised hair.
2. Work on clean, dry hair. Divide into small sections for consistent results.
3. For straightening, place the plates near the roots and glide smoothly to the ends in a single, steady pass.
4. For waves or curls, rotate the straightener as you glide along the section to shape the desired movement.
5. For salon treatments using CoverUp sheets, apply them to the plates and work at a controlled maximum of 130°C as directed.

Important: CoverUp sheets are designed for use only with Bio‑Infrared flat irons such as Slim2 and must be used at a maximum temperature of 130°C.
