Final answer:
The techniques for permanent waving are similar for both men's and women's hair, involving chemical treatments that alter disulfide bonds to achieve a lasting hairstyle.
Step-by-step explanation:
When it comes to perming hair, the fundamental techniques involved in permanent waving do not significantly differ between men's and women's hair. Both techniques utilize chemicals to disrupt and re-form disulfide bonds within the hair stands, irrespective of gender. Temporary waves result from a disruption of hydrogen bonds that can be reshaped as the hair dries, creating new hydrogen bonds and thus a new shape.
The permanency of a 'perm,' whether resulting in curls or straightening, comes from the alteration of disulfide bonds, which are more durable than hydrogen bonds. Overall, the key processes for achieving a permanent hairstyle are the same and are not dependent on the gender of the individual.
