  6. Electric curling irons • Electric curling irons have a heating element with a controlled thermostat that allows the iron to maintain a constant temperature • A good electric iron should be able to be left on for a long period and maintain the correct temperature. • SAFETY: The electric curling iron should be tested on a tissue paper. After being heated, if the iron scorches the tissue paper it will burn the hair. Cosmetology I: Thermal Hairstyling

  7. Marcel curling irons • Marcel irons are heated in a stove • SAFETY: The temperature of a marcel iron must be tested on a tissue paper. After being heated, if the iron scorches the tissue paper it will burn the hair. • SAFETY: Fine, lightened and damaged hair are able to withstand less heat than healthy hair. • Always be aware of the client’s hair texture when performing a thermal curling service.

  8. Care of curling irons • Always keep irons clean and free from rust and carbon. • Washing the irons in a soap solution containing a few drops of ammonia will remove dirt and grease. • Rust and carbon can be removed with fine sandpaper, or steel wool with a little oil. This procedure will also polish the iron. • Take care not to overheat the irons. New irons are tempered in the factory, and overheating them will cause them to lose their temper and become ruined.

  9. Curling iron: Proper holding • Practice each method to determine which one is the most comfort and control. • Practice turning the iron in a downward circular motion. You will have to shift your thumb to help in the turning motion. • Do not move or sway the iron while rolling; all movement is done with the fingers. Cosmetology I: Thermal Hairstyling

  10. Exercise using a cold iron • Start with the iron on top of the hair strand. • When making the curl, rotate the iron one half-turn and then one full turn back to starting position. • Open irons slightly and slide down no more than and inch, then clamp. • Turn irons backward for a full turn toward you. • Return irons to starting position. • Release.
