What is the process of a perm?

The process of a perm involves wrapping hair around rods and applying a wave solution. This method permanently alters the hair's structure and creates curls or waves. The wave solution, often containing a chemical called ammonium thioglycolate or a similar agent, works by breaking the disulfide bonds in the hair. Once the hair is wrapped around the rods, the solution is applied, enabling the hair to take the shape of the rods. After a period of time, a neutralizer is used to reform the disulfide bonds in their new shape, securing the curls or waves.

The other options do not accurately describe the perm process. Applying heat to style hair refers to techniques like flat ironing or curling, which do not change the hair's structure permanently. Trimming hair to enhance texture is related to haircutting and does not involve the chemical process of perming. Coloring hair with permanent dye is a separate service that changes the hair’s color but does not alter its texture or shape like a perm does.
