Flat Iron

A flat iron, also known as a straightening iron or hair straightener, is a heated tool used to temporarily straighten hair. It typically consists of two heated plates that are pressed together, clamping sections of hair between them. The heat alters the hair's hydrogen bonds, allowing it to be reshaped. The effect is temporary, and hair will generally revert to its natural texture after exposure to moisture or washing.

Flat irons come in various sizes and utilize different materials for the plates, such as ceramic, titanium, and tourmaline. Different materials offer varying levels of heat distribution and potential benefits regarding hair health and damage reduction. Some flat irons also include adjustable temperature settings, allowing users to customize the heat based on their hair type and desired style.

The use of a flat iron can be damaging to hair if not used properly. Excessive heat, repeated use, and improper technique can lead to dryness, breakage, and split ends. It is generally recommended to use a heat protectant spray before using a flat iron and to avoid using it on wet hair.
