Hair straightening refers to a technique that fixes curly or strongly wavy hair in a straight state.

The method of hair straightening begins by using a straightening agent to break the bonds in the hair, creating a soft hair state.
Then, heat is applied using an iron or similar tool to straighten the hair.
Finally, another straightening agent is used to re-bond the hair, completing the hair straightening process by keeping the straightened hair in place.
