What is the difference between hair perm and hair curling

In order to make themselves more handsome and beautiful, many people choose to have a beautiful hairstyle. Perming and perming are among the more popular ways. However, many people cannot tell the difference between perming and perming, which often causes some embarrassment and misunderstanding. Although perming and perming have some similarities in many aspects, there are fundamentally great differences between the two. Here are some methods to distinguish between perming and perming. I hope it can help everyone.

The so-called perm is to use chemicals directly on the hair and then use curlers to create waves. Perming is to use chemicals and machines to create waves on the hair.

Both perming and perming change the hair to achieve the purpose of expressing the desired hairstyle. The quality of hair is distinguished according to the value created by the hair style. Comparing the effects of perming and perming can let you understand the difference in performance of the two hairstyles, analyze the expression style of the hair, compare the difficulty of hair, the different hair care methods, give you the different characteristics of perming and perming, compare hairstyles, find the expression characteristics of your favorite hairstyle, and classify the hairstyles you think are good.

The principle of perming is that the ammonium sulfate (alkaline) in the special perming solution enters the cortex through the hair scales on the surface of the hair, changing the protein chain structure of the hair to form curls. Perming generally uses reducing chemical solutions to break up the small springs of cysteine, breaking the sulphur-sulfur bridge bond of cysteine ​​and becoming two cysteines. At this time, the amino acid chain links of the hair loosen and can be manipulated by people, curling into a certain waveform. Then apply fixative to make the cysteines that break the small springs combine in pairs nearby to form new springs and fix the hairstyle.

During the hair perm and hair growth process, the alkaline components and oxidation in the solution will damage the scales on the surface of the hair. Leaving the internal structure of the hair unprotected will cause the loss of internal moisture and nutrients, which is harmful to the hair, scalp and hair follicles. It will more or less denature the hair's keratin, making the hair prone to yellowing, brittle, dull and inelastic. Experts believe that perming should not be done too frequently, and should not exceed four times a year.

There are many hazards of perming and hair growth, and chemical substances are the most worrying among them. The hidden and serious hazards of perming, namely the chronic damage to the human body, may lead to various cancers after many years. The scalp has the most densely packed hair follicles in the human body. Chemical toxins can be absorbed into the body through the scalp hair follicles. With long-term use, chemical toxins accumulate in the body and enter the human blood. If the dye concentration is too high or dyeing and perming are too frequent, it will damage blood cells. It may cause leukemia or lymphoma, and may also cause intractable diseases such as bladder cancer, breast cancer, and aplastic anemia.
