Hair straighteners

Straightening irons, straighteners, or flat irons, not to be confused with clothing irons, work by breaking down the hair's hydrogen bonds found in the hair's cortex, which cause hair to bend and become curly. Once the bonds are broken, hair is prevented from holding its original, natural form, though the hydrogen bonds can re-form if exposed to moisture.
