The wonder trade has lengthy looked for a safer different.

Polyphenol Manufacturing unit, a Korean beauty-tech startup, believes it has discovered the reply. At CES 2026, the corporate will current Grabity StraightMAX, a hair-straightening expertise powered by naturally derived polyphenols. In contrast to chemical relaxers, StraightMAX doesn’t break the hair’s inner disulfide bonds. As an alternative, it makes use of plant-based polyphenol polymers to coat the hair floor with an invisible layer. When heated and dried, this exterior layer reshapes the hair shaft, reworking even tight curls into easy, straight types in only one or two makes use of.

What makes StraightMAX particularly progressive is its twin functionality. The identical molecular precept that straightens hair can be reversed to create waves or gentle curls, turning it into a flexible styling platform.
