What do we mean by a hair straightener?

A hair straightener is a product whose purpose is to change the shape of the hair from wavy or curly to straight. It has the same scientific basis as a hair perm, which is why the chemical composition of the cosmetics used is very similar and the most important difference is the cosmetic form which, for straightening hair, is usually a hair straightening cream.

Aspects to take into account when straightening hair.

A hair straightener alters the structure of the hair in an irreversible way
, so extreme precautions must be taken. Before straightening the hair, the condition of the hair should be observed. It should be ruled out in the following cases:

• When the hair shaft and hair is very damaged.
• Too frequent straightening.
• In cases where there are traces of colouring with metallic or vegetable products such as henna.
