How does a curling iron work?

The structure of the hair can change under the effect of heat. Because by removing moisture from the hair, it is possible to redefine its shape. A curling iron (or curling iron) allows you to transform straight hair into beautiful curly fleece, while a straightener tames curls by stiffening them. However, the result obtained only lasts until the next shampoo. Our hair contains small chemical bonds capable of breaking easily. All it takes is for the air to be humid for the spell to break and everything to go back to how it was.

  • A perm keeps beautiful curls longer.
  • Today, curling irons are electric and consist of a smooth heated tube.
  • For best results, use it on dry hair.
  • In 1872, the corrugating iron was born in Paris. Composed of polished metal rods, this object was heated directly over a fire.
  • In ancient Rome, metal tubes were used which were heated in hot ashes or into which previously heated rods were inserted.
  • Excessive heat can damage hair.
