Final answer:
Free form blow-drying is less structured, allowing hair to dry naturally, while stylist blow-drying techniques involve using tools to shape the hair. Temporary waves are heat-styled while permanent waves are chemically set. Both processes alter hair's disulfide bonds to achieve the desired style.
Step-by-step explanation:
The differences between free form blow-drying and stylist blow-drying techniques lie in the methods and tools used, as well as the end results. Free form blow-drying generally involves using a hairdryer to dry the hair without a defined style, allowing the hair to fall naturally, which can be ideal for quick dry-off sessions or when aiming for a more casual look. On the other hand, stylist blow-drying techniques are more structured. This method often involves using tools such as round brushes, flat brushes, or other styling implements to create a particular shape, volume, or sleekness, depending on the desired outcome.
While discussing hair styling, it's also important to note the processes involved in creating temporary and permanent waves. Temporary waves are typically formed with the help of heat tools such as curling irons, which reshape the hair until the next wash. Permanent waves, or perms, involve a chemical process that breaks and reforms the disulfide bonds in hair strands to provide long-lasting curls. In both processes, the steps in formation of these styles are critical, whether for a temporary look that lasts a day or a permanent change that endures for months.
