Description
Upgrade Keratine is a professional hair straightener featuring Upgrade’s Bio-Infrared technology. Instead of concentrating heat on the surface, Bio-Infrared delivers red-light heat within the hair fibre for a uniform, controlled style. This approach supports reliable salon performance while respecting the hair’s structure.
Bio-Infrared tools allow you to work at lower temperatures compared with traditional straighteners, helping reduce thermal stress while enhancing smoothness, softness and shine. In salon services, Bio-Infrared heat also supports the absorption of care treatments without additional processing time.
Keratine sits within Upgrade’s professional Bio-Infrared range. It is designed for precise, consistent styling and to complement treatments that benefit from gentle, effective heat activation.
How to use
- Ensure hair is clean, dry and thoroughly detangled before styling.
- Divide hair into manageable sections to maintain control.
- Select a suitable temperature, starting lower and increasing only if needed.
- Place the straightener near the roots and glide smoothly to the ends in a steady pass.
- Repeat on the remaining sections, allowing hair to cool before touching up if required.
- If used alongside a treatment, follow the treatment’s instructions and activate as directed with the straightener.
