Alkaline perms are a type of hair perm that uses an alkaline solution to break down the hair's protein structure, allowing it to be reshaped into curls or waves. This method typically involves a higher pH level, which helps to create stronger and more defined curls. Alkaline perms are suitable for various hair types, especially those that are resistant to curling. The process usually includes applying a perm solution, wrapping the hair around rods, and then neutralizing the curls with a separate solution. Unlike acid perms, alkaline perms tend to produce firmer curls that last longer, making them a popular choice for individuals seeking a more dramatic change in their hairstyle.
