The phrase "give a permanent" typically refers to a hairstyle treatment called a permanent wave or perm. A permanent wave is a chemical process used to alter the texture and shape of hair, usually from straight to curly or wavy. The term "permanent" indicates that the change brought about by the treatment lasts for an extended period, until new hair grows out.
During a permanent wave, hair is first wound around rods or curlers, and then a solution containing chemicals, such as ammonium thioglycolate, is applied. This solution breaks down the protein bonds in the hair, allowing it to be reshaped. After the hair is suitably altered, another solution, usually containing hydrogen peroxide, is applied to reform the broken bonds, resulting in the desired curl pattern. Finally, the hair is rinsed, neutralized, and styled as desired.
A permanent wave can provide long-lasting, natural-looking curls or waves that require minimal maintenance. The duration of the perm depends on various factors, including the individual's hair type, care routine, and rate of hair growth. Perms generally last several months to a year before the treated hair needs to be retouched or redone.
The term "give a permanent" is often used in the context of visiting a hairstylist or salon to have a permanent wave treatment performed. It denotes the act of receiving a chemical process that permanently changes the structure of the hair, resulting in a lasting curly or wavy hairstyle.
