A "Hot Perm" is a hair treatment that uses heat to create curls or waves in the hair. This process involves wrapping sections of hair around heated rods and applying a chemical solution to help set the curls. The heat helps to activate the chemicals, allowing for more defined and long-lasting curls compared to traditional cold perms. Hot perms are popular for their ability to add volume and texture to hair. They can be customized to achieve various styles, from loose waves to tight curls. It's important to consult with a professional stylist to determine the best approach for your hair type and desired look.
