When heated and dried, this exterior layer reshapes the hair shaft, reworking even tight curls into easy, straight kinds in only one or two makes use of.

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