What Is Permed Hair?
Perming chemically alters your hair structure to form different types of curls or waves. The technique to straighten hair is called hair relaxation. It breaks down the disulfide bonds in your hair and gives it a new structure. There are many techniques to perm your hair:
How Perming Works
The disulfide bonds in the hair are broken using reducing agents like thioglycolates and bisulfites (1). These reducing agents permeate through the cuticle and outer layers of the cortex to break the disulfide bonds. Alkaline agents are used to lift the cuticle scales so that the reducing agents can enter the cortex (1). The hair fibers are set in curlers or rods to give the hair the desired curl or wave pattern. Once the pattern sets in, the perming process in the hair fibers is neutralized using an oxidizing agent like hydrogen peroxide. The traditional style of perming was wrapping hair in rods. After that, the perming solution would be applied so the hair would set in curls or waves. Once the hair is set, the solution is rinsed off, and a neutralizer is used to stop the perming process. Over time, new formulas and techniques using different objects to give you a particular type of curl or wave. Let’s look at the different perming techniques.
Different Perming Techniques
1. Digital (Hot) Perm
With digital or hot perms, the hair is first processed with a relaxing treatment, which helps break the bonds in your hair. Then, your hair is shaped with heated curling rods. The thickness of the rods depends on how loose or tight you want your curls to be. Your hair is finally put in hot rollers that are attached to a device that helps regulate their temperature. This process can take up to four hours or more, depending on the length and thickness of your hair. With the digital perming method, you can get curls of varying lengths, which helps give you a very natural look. Your hair is usually straight while it is wet and curls up as it dries. This method was specifically designed for East Asian hair and only works for people with thick hair. The process is expensive. However, it is less damaging to the hair than other methods.
2. Cold Perm
Cold perms are the traditional way to perm your hair. In this process, your hair is first soaked with an alkaline solution. It is then tightly wound into small curls using rollers. The tight curls help shape your hair into tight ringlets, which are not possible to achieve with the digital perming method. These tight ringlets do not look natural at first, but over time, they will relax and look more natural. The process can take from 2 to 2.5 hours. The curls you achieve with this method remain curly even when wet or when you use a product. The process is more affordable than the digital method and works on almost all hair types. With the right care, a perm can last up to six months. Here are a few tips to help.
