Permanenttiaineet, often referred to as perming solutions, are chemical formulations used in the beauty industry to permanently alter the structure of hair. The primary purpose of these solutions is to create lasting curls or waves in straight or loosely textured hair. This process involves breaking and reforming the disulfide bonds within the hair's keratin protein structure.

The active ingredient in most permanenttiaineet is typically a reducing agent, such as ammonium thioglycolate or a derivative. This agent penetrates the hair shaft and breaks the disulfide bonds that hold the hair's natural shape. Following this, the hair is wound around rods of varying sizes to achieve the desired curl pattern. A neutralizer, usually an oxidizing agent like hydrogen peroxide or sodium bromate, is then applied. This neutralizer reforms the disulfide bonds in their new, curled configuration, effectively setting the style.

Different types of permanenttiaineet exist, catering to various hair types and desired outcomes. Acid perms are generally milder and suitable for damaged or chemically treated hair, offering looser, more natural-looking waves. Alkaline perms are stronger and more effective for resistant hair, producing tighter, more defined curls. The application process requires careful attention to timing and product selection to avoid hair damage.

The effects of a permanenttiaine treatment are considered permanent in that the hair that has been chemically altered will retain its new texture until it grows out. However, new growth will revert to the hair's original texture. Maintaining permed hair involves specialized shampoos and conditioners to keep the curls defined and healthy, as the chemical process can leave hair more porous and susceptible to dryness.
