Final answer:
The function of the permanent wave neutralizer in cosmetology is to stop the chemical reaction and stabilize the new shape of the hair during a permanent wave or perm process.
Step-by-step explanation:
The function of the permanent wave neutralizer in cosmetology is to stop the chemical reaction and stabilize the new shape of the hair during a permanent wave or perm process. When a person gets a perm, the hair is treated with a waving lotion or solution that breaks the disulfide bonds in the hair.
The waving lotion or solution softens the hair and allows it to be reshaped. After the desired shape is achieved, the hair is rinsed with water to remove the waving solution and then a permanent wave neutralizer is applied. The neutralizer helps to restore the disulfide bonds in their new shape, so the hair retains the desired curl or wave.
Without the use of a permanent wave neutralizer, the perm will not be successful and the new style will not last as long. The neutralizer is an essential step in the perm process, ensuring that the hair is set in its new shape.
