And conserve the hair and hair care ~ ~ and know that your hair why do not roll out. And so read the whole paper ~ ~ to understandPerm is the use of chemical and physical methods to make natural straight hair, curly shape formation. The cold wave perm methods

perm, the physical volume of hair in different core diameter and shape of the volume, in the perm of water under the action of the first dose, second-rate about 45% of the important is cut off, and become a single disulfide bond. These single core disulfide bond in the volume under the impact of the diameter and shape, resulting in compression and displacement, and left many gaps. Perm second dose of the oxidant water into the fat body, the expansion in the gap becomes larger, so that the original single-sulfur bond can not be back in place, and with the rest of the adjacent one of a disulfide bond re-form a new group second-rate of the criticals, so that the hair in the birthal second-rate produce changes in the angle of the crucials to make the changes permanent hair volume

cold wave perm agent method and tools used

agent perm perm perm agent commonly used method for two fluids, the first solution for the perm solution (perm lotion), the second solution for the neutralizer (styling agent), both of perm solution is do with use. Perm solution (perm lotion) expansion of the character is to soften the hair there is plasticity, coupled with the physical impact of bar curls, curly hair, the shape is formed. Neutralizer (ie, stereotypes solution) is to stoppage the perm solution (ye ting zhi) function, so that the curled shape fixed to assert a constant during the straight. Perm of water is a reducing agent (first dose) and oxidant (second dose) formed.

one, the first dose: the main component of ammonia, which is alkaline. The purpose is to use the base to expand and soften the epidermis, the main agent for penetration and absorption of sulfides. However, excessive use will cause side effects of protein undermine hair, causing hair loose structure, porous and no flexibility.

Second, the second agent: the main component as the oxidant, hydrogen peroxide or bromine mainly sodium-based. Oxidants for the purpose of using a fixed volume level. However, excessive use will cause the hair dry, open *, broken, faded and so on.

curls curls bar (juan3 fa1) There are many bars, generally impervious plastic bar better. Bar curls with chopsticks produced water befactor of its easy to easily penetsize perm, medium, and two kinds of liquid, affecting the quality perm, which should not be used. Curl bars are large (coarse), medium and small (fine) of points, for different characters and different curl demand.

In general the open pores

and 30% decomposition of disulfide bonds is required 35 ~ ~ ~ `40 minutes. Damaged hair can reduce some of the time, because there is no damage to hair cuticle closed and there is no protection. Thereby reducing the decomposition of 30% of the disulfide bonds of time. However, the number of disulfide decomposition can not be changed. (The number of decomposition the number of disulfide bonds. You can adjust the pattern as you as a manner of expression)

and how to determine the number of disulfide bonds break down how much? See the experiment:

1. straight hair phenomenon \Reasons, a lack of medicine, 2 hair stiff, 3, no dry cleaning, etc. \

2. slightly curly hair phenomenon occurs,[link widoczny dla zalogowanych], \5 minutes in the park \

future work is to split bars, shampoo. Then you can use hair conditioner to help restore supple always bright.

operating procedures of cold hot cold hot and methods

operating procedures, generally: the hair curling → Partition → points were rushed to the perm solution heat → → → split bar coated neutralizer rinse.

① hair properly after shampooing hair Kaigan district, the head hair is divided into districts (Department) to curly hair, and can be divided into 9-10 zones.

② points were curly hair, on the basis of the partition, the first match in the hair with a comb bars separate the length and diameter of an hair, lift up with his left hand, in the hair under the lining of a water permeability good soft tissue (cold hot paper), with a finger grip, with the curly hair from the hair volume bar to the hair root, with a rubber band fixed. Can be divided into one share, volume share, until all the hair; his hair curled, some stocks, coated with perm solution.

share ceded to straight hair, the width of the bar length commensurate with the curly hair. Curly hair when the force should be uniform, the hair and scalp lift to assert a certain angle, usually 90 ° angle or 135 ° angle, the angle of hair determine the direction of the hair root standing.

bars changed hair, hair design requirements should be based on, which determines the angle of hair and hair roots of standing, dry shape, hair facial expressions, can determine the flow of the hair, the hair is durable, has a closely related to the difference between electric hair and perm

③ wearing a plastic hat hair all rolled up, and then absorbed in the volume of each hair coated with perm solution, and then wear a gas-tight (ye4 _ran2 hou4 dai4 shang4 bu4 tou4 qi4) plastic cap, will cover all the hair in the cap, through the normal human body temperature, to promote the role perm solution. Time set cap should be based on the concentration of perm solution (according to manufacturer's instructions) may be, generally 15 to 25 minutes. Sometimes under the hair, curly requirements, set the temperature and other factors, to be adjusted. Generally speaking, short hair, some of the valuables; hair is coarse the hours are long; requires some longer hair, more volume; requires less hair, shorter time to volume; room temperature for longer time can be low; room temperature, the time can be high shorter. As in winter, room temperature is too low, can also be heated hair, or use hot towel wrapped in plastic cap external heating, to promote the role played perm solution.

plastic cap containing a certain time, you can open one half of the volumes, with both hands holding the bars at both ends of hair, the hair will release half of the push, if the hair has become wavy and curled a strengthful, that perm quality has reached the requirements, you can end this perm (tang fa) process, take off plastic cap. Inability to curl not found the formation of waves, indicating that not enough time perm. (Shi jian bu gou _) have to wait a few minutes. To take off plastic cap.

④ rushed off the plastic cap of the hot liquid after washing hair with warm water volume (do not remove hair bars), rushed to the hair perm solution on the volume, so stop playing the role of perm solution, and then Kaigan made the appropriate volume of water, so as not to affect the quality of coated neutralizer.

⑤ coated neutralizer (stereotypes water) made in each volume evenly coated neutralizer (ie, stereotypes of water), to penetrate to all the hair, over 5 minutes, then the volume in the hair Enlightenment painted a neutralizer, and then wait 10 minutes to make curly hair fixed. Although this process is very simple, but important, if the neutralizing agent is not coated or placed through lack of time, did not play stereotypical roles, hot roll straight hair will be restored, resulting in

syrup crazye the bars in 15 to 20 minutes (fen1 zhong1) the time / You can open a hair in the back of the paper to see / contact gently pull hair piece appeared perm 3 times failed.

⑥ remove all the hair clear upd bar bar flush with (chai qu quan bu juan fa gang _yong) warm water, rub the hair first with shampoo, rinse to hair perm solution and the residual and agent, and then use hair conditioner hair care, and then warm water clean. After perm the hair must be clean, otherwise the liquid residue, will make the hair become brown and dull.

focus on issues

1, accurately select the perm of water: the quality of the hair according to customer choice. Scalp hair, perm should check the situation before the perm lotion is a chemical agent, a certain fury, if the hair and scalp harm should not perm, so as not to hurt the hair, the scalp inflammation. Have caused little injure in the hair, should be handled by the gradeer after the perm. Inflammation of the scalp to injure or definitely not (_tou pi you hua po huo yan zheng de jue dui bu) should be perm. Also, prenatal and postnatal body is weak, should not be perm. Perm cycle should not be too short, generally three to six months time is appropriate. Beauty and Health

2, the process of the electric hair, hair swelling degree and the number of sulfur chain is changed, the first dose of medicine decided to stay on the hair length of time, so it is obviously impossible to use us a single hot electric hair time. The best step is to always check the curvature of the hair.

3, inspection methods: alkaline water to the hair perm curvature is reached as a proclamation, low-acid and alkaline water to soften the extent perm as a standard.

4, No. 1 if the residence time in the hair (ji ru guo zai tou fa shang ting liu shi jian) is too long, the hair will reduce the volume level and flexibility. Therefore, after staying some time should be checked every 3 to 5 minutes once, each inspection should be carried out in different locations.

5, the first one must be flush, or hot after the severe impact of the hair quality. Flushing temperature has some influence on the curl: 60 degrees to 30 degrees water temperature can, in this temperature range (du4 shui3 wen1 jun1 ke3 _zai4 zhe4 ge4 fan4 wei2 nei4 shui3 wen1) the more the higher the degree of roll paper.

6, a second dose of high-end brands and focus on the absorption of water, but the stay must not exceed 10 minutes.

7, washing the second dose, the first flush and then removed with a hair volume bar clean, so the degree can be a solid curly hair. So that when the second dose flushing of water temperature on the hair also affect the curl: 60 degrees to 30 degrees water temperature can, in this temperature range the more volume the lower the volume level. (Flush with the first dose of the opposite temperature)

8, hot after-care is very important, because just after the scalp perm very comfortable, the hair is relatively weak and, therefore, applied Song Wei Hua Su City or white hair to strengthen after-care hot foam drilling to avoid this phenomenon.

9, accurate guidance on how customers comb, hair care, styling products to use to explain the purpose and function, which can effectively foster the image of salon and hair stylist

10, droplets on the skin and clothing operation should be to prevent the cold hot cold hot droplets in the facial skin and clothing, so with the liquid dose to moderate, without rendering the fall, if accidentally drops of liquid on the skin should be wiped immediately with cotton. Before the manner at the hairline should put some petroleum jelly to protect the skin and hair volume with the cotton cover your sides to prevent liquid falling. Should also be put on cloth and a dry towel around, so that liquid will not drip on clothes, causing clothes fade.

perm chemical process:

open the cuticle by ammonia, so that the smooth ethanethiol acid disulfide bond cut into the cortex, and through the perm tool, change the chain bond (gong1 ju4 _gai3 bian4 lian2 jian4 jie2) structure, oxidants in the use of sodium chloride and sodium dioxide, key chain, so that a fixed shape. (PH value of water 8 perm toils best, but not more than 9.5 PH value, PH value is too high, as will excessive impair hair)

major components and component analysis:

1, reducing agent (1)

(1) ethanethiol acid (thio): basic material, only that it can cut off the hair and the most strong disulfide bond.

(2) ammonia (ammonia): alkalength substance (PH value is 9 degrees) allows expansion of the hair, open pores, so that other ingredients to enter.

(3) moisturizing agents: maintaining humidity and shiny hair, hair to add moisture and nutrients.

(4) buffer (balanced agent): China and the basic characteristics, the chemical balance of the hair.

(5) aromatic: to cover the odor of ammonia.

(6) of different products with different additional ingredients.

2, chlorinating agent (2) half the time as a reducing agent.

(1) Sodium chloride: Restructuring and fixed chain of key organizations. [link widoczny dla zalogowanych]

(2) Sodium peroxide: (hydrogen peroxide) to help re-disulfide bond, the chain bond oxidation of fixed shape.

II, 1, made in a geometric potential (the mean length (_zai4 yi1 ge4 ji3 he2 fa1 shi4 zhong1 _zhi3 chang2) issued), if the upper part of the small hook (detail relationship between the hair down sense), the relative relationship of the lower part of the details of the hair upward sense, the farther down the greater the overall density of the Department of hair down the outline of the relationship between hair bundle moved flu. Because then the whole up and down the upper part of the macro expansion, the lower part of contraction.

Third, no burns and no curly hair than straight hair burns, arc made sense of the hair down relationship, such as long hair and short hair than the arc, but if \see \close contact with the rest of the hair, then the arc made sense of the overall hair down relationship, relationship tip hair upward sense). Therefore, we must deal with such a abated-fat arc between its hair, it's somewhere (such as the upper) high levels of detail (or reduce its unit volume) deal with it. The difference between electric hair and perm hair

relatively curved or very soft hair, if low-Yang angle (between the hair unit volume, shifting the relationship between a sense of hair), with a knife outside the cut, make the hair easier to play bend (arc), when a hair is between the more intimate, then move up the hair a sense of relationship, so in general do not handle it this way. (1) If only this treatment, Thinning is done, use the ramp to the hair cut short cut some of the beam, to cut off the overall length of the close relationship between hair bundle, or knife to cut the amount of hair cut too flat small, so that the overall relationship between the hair down feeling. (2) We can handle the relatively high level of detail within the hair to weaken their cohesion, after handling them. The above analysis we can see, before we deal with the hair (dry hair), the matter straight hair, curly hair, it is necessary to observe all parts of hair or hair bands hair relationship relationships, and then look at it in detail.

about physical damage, I would like to mention the hair cuticle epidermis (which is after hours start physical jeopardize). The plasticity of the hair is very strong,[link widoczny dla zalogowanych], when wet, heat, alkali would become soft swelling; the other hand, the case of dry, cold, acid will roughen contraction. Therefore, the former will open the cuticle, which will be closed. Here we let it do the whole process of hot plasma. First, wash your hair Well

(cuticle open), and then blow dry (cuticle closed), then the one that softener (softener is the base, so the pores open), may be Oh, look at the steam plant (cuticle even been opened), softening after a good flush and then bloearng dry (cuticle closed), and then let the hair clip (plywood temperature is higher, so the pores open), after a good clip on two shape (like an oven freeze hair, cuticle and closed), ten minutes, then rinse off (open), and finally dried form (closed). Article order:

hot plasma above the whole mode is on, that is, a cuticle is opened, one will be closedownd. Let me offer an example, there is a spring in your hands, stretching it as you will, a will to condense it, and then repeat these two actions. Down a few times, your hands into the death early spring spring myself. Therefore, the hair looks like a spring, is not withstand repeated ~~~~~~~~~

hair dye chemical deviates which occur when

hair keratin proteins, amino acids connected toobtainher by a series. The long chain molecules like amino acids is one of a link. More hair in an amino acid called cysteine. Placed in different parts of the two cysteine sulfur to sulfur bond connecting the bridge to form a cystine. These cystine mimicking a steadily smaller spring, so that there is a certain shape and hair elasticity. When you burn the hair, the hair cystine sulfur in sulfur bridged slack off heat, and then under the strong, the hair will change shape and become wavy. Perm, and inflicting burns similar to, but it is to use alkaline agent infiltrating the hair, and then roll the hair curl electric molding. However, this heat distortion, much like stretching, twisting the spring, and slowly turn restitution. Therefore, perm, very hot hair is not easy and lasting.
