L'Oréal's infrared-powered glass hair straightener could reinvent the category

L'Oréal unveiled the Light Straight + Multi-styler, a glass‑plated straightener using patented infrared light that operates at lower temperatures than many traditional stylers; the device is slated for a global 2027 launch and pricing is to be confirmed.

L'Oréal has unveiled the Light Straight + Multi-styler, a glass‑plated hair straightener that uses a patented infrared light technology and was shown at CES 2026. The company describes the device as operating at lower temperatures than many conventional stylers and says the light both generates heat and helps temporarily modify bonds in the hair. L'Oréal presented a working prototype in a controlled demo and says the product is still in development. The firm expects the device to join its wider line of light‑based beauty gadgets. Key details: - Plates are made of glass and the device uses L'Oréal's patented high‑powered infrared light. - L'Oréal said the straightener does not exceed 160°C (320°F), lower than some traditional stylers. - The company claimed the Light Straight works three times faster and leaves hair twice as smooth, as reported from a CES demo. - The infrared light itself is invisible; prototype LEDs were red while the final model is planned to glow blue. - L'Oréal has filed over 170 patents related to the specific light used in its hair devices. - The Light Straight + Multi-styler is scheduled for a global launch in 2027 and pricing is to be confirmed. Summary: L'Oréal reports the infrared approach allows styling at lower temperatures and may reduce heat exposure to hair. The company is still finalizing the product's form factor and capabilities; a global launch is planned for 2027 and pricing is undetermined at this time.
