Principle of perm
There are two kinds of perms: physical perms and chemical perms. Now most of them are chemical perms. In the process of perm, the scales on the hair surface will be destroyed. Special perming liquid enters the cortex through the scales on the hair surface, changing the protein chain structure of the hair, forming curly hair, and then applying fixative, the hair becomes a new shape. The principle of perm is that the alkaline components and oxidation in the liquid medicine will destroy the scales on the hair surface. If the internal structure of hair is not protected, it will make the internal water and nutrients lose, which is harmful to hair, scalp and hair follicles, and will denature the keratin of hair to a greater or lesser extent, making hair easy to yellow, brittle, dull and inelastic. Whether it's good or bad, chemicals used for perming will do harm to hair. Pregnant women and children should not have perms. The principle of perm technology is to soften the hair scales first and let the medicine enter the second layer of hair: cortex, thus changing the molecular structure of cortex. Let's look at the relationship between cortex and our hairdressing. The cortex is composed of salt bond, hydrogen bond, disulfide bond and amino bond. Hydrogen bonds and salt bonds have a * * * characteristic, which is broken when meeting water and recombined when meeting heat. Because perm is harmful to hair, it is very important to repair it after perm. After perming, vitamin B complex and carotene can be supplemented to help reduce the injury. This is because vitamin B 12 can promote smooth blood circulation, improve the utilization rate of protein and promote the growth and development of head cells. Carotene can absorb ultraviolet rays and reduce the degree of oxidative discoloration of hair. Taking vitamin B together with carotene can make hair more moist and shiny.
Some points to pay attention to when ironing your hair
1, you can't directly bake oil when perming.
The process of perming destroys some hair structures, and direct oil baking will affect the perm effect.
2. You can't dye your hair directly after perm.
If these two processes are carried out at the same time, it will not only affect the effect after perm, but also affect the color durability of hair dyeing.
3. Know your hair quality before perm.
Perm solution has certain damage to hair, and the perm time should be at least three months, preferably more than half a year. Regular perming will make hair lose its luster and elasticity.
4, the perm effect is not good, can not immediately re-perm.
Re-perming will make hair more fragile and completely damage health. Everything needs a break.
5. After trimming the perm, you need to use mousse and hair dryer to set it.
Asian people's hair is characterized by smoothness and needs to be shaped with a hair dryer. To create special effects, we can also use some hair accessories.
6, in order to reduce the absorption of scalp drugs or allergies, perm can only deal with the middle and tail of hair.
7. It is best to choose a cold perm for a perm.
The non-flowing thermal temperature during perming shall not exceed 80 degrees Celsius, and the flowing temperature during hair drying shall not exceed 120 degrees Celsius. Because it exceeds the temperature, the hair expands and breaks, and then breaks, and its elasticity weakens and loses its luster. In fact, there are many styles and types of perms on the market, and different perming techniques have different hair styles and fashion sense, so many young boys and girls like perms very much. The principle of perm is to soften the hair with some chemicals and then bend it at high temperature. Therefore, perming is very harmful.
