2. Description of the Related Art Conventionally, there is a so-called perm forcibly giving a habit to make one's own hairstyle, and this perm is operated at a beauty salon or a barber shop.

This perm includes what is called a straight perm forcibly straightening curly hair, and it is very popular with people, especially women, who are worried about curly hair and want to have a straight hairstyle.

The treatment of this straight perm is for washing hair,
Hair diagnosis, application of the first agent, penetration of the first agent, washing with water, correction of habitual hair, application of the second agent, washing with water, and blowing are carried out in this order, and the ingredients of the first agent and the second agent are changed for each beauty salon. There are some straight perm treatments because they are differentiated by adding new treatments between the above treatments.

Of these, straightening of habitual hair is one of the most important treatments for applying a straight perm. First, a part of the hair whose shape is easily changed by the first agent is separated and flattened. Then hold it with your index and middle fingers. Next, the hair is pinched between the two arms of the curling iron and moved from the scalp to the tips of the hair, forcibly straightening the curly hair. Hair pressing parts are provided inside the two arms of the curling iron. The hair pressing unit is provided with a heater, and the heater is heated to apply heat and pressure to the sandwiched hair to correct the habit hair.
