A:
1, shape
2. Texture
Step 3 color
4. Direction
5. Structure
2. What is the basic concept of acid care? Short Answer Questions
A: Acid protection is actually a kind of primary color hair dye without ammonia, which contains cationic polymer, which can effectively protect hair and avoid being hurt during dyeing.
Please briefly describe the principle of dyeing and perm?
Dyeing is the addition of hairstyle, that is to say, a single Asian hairstyle, if it is not decorated with color and perm in the later period after haircut, is simply an incomplete design, which is not enough to reflect the characteristics and advantages of this hairstyle. Thereby chan that color or curl of Asians. When dyeing hair, chloramine molecules in hydrogen peroxide open the epidermis of hair through ammonia gas and withdraw from natural pigment. Hydrogen peroxide expands artificial pigment due to the action of ammonia gas, and then the artificial pigment will merge with the remaining natural pigment, thus stopping between epidermis and cortex for coloring. This is a kind of polymerization. Perm is through softening-setting-setting. The ammonia in the reducing agent opens the hair scale, which expands and softens, helping mercaptan enter the epidermis and cut it off. The curling tool recombines the chain bond structure, so that the oxidant connects and fixes the chain bond, and achieves the effect of cold perm. This chemical change is called reduction.
4. What factors are related to the degree to which the target color can be completely achieved?
1, temperature: the higher the temperature, the faster the reflection, and the lower the temperature, the slower the reflection.
2. Hair color depth (primary color): Due to external influence, perm treatment and other factors, the color of hair shaft and hair tail is often lighter than that of hair root.
5. How to operate complementary colors? Short Answer Questions
Answer: new hair complementary color steps below 30 mm
1. Divide the hair into four areas.
2. Start from the neck and spread at the root of the first layer of hair pieces. Pay attention to spreading new hair pieces only at the root.
3. The other three areas are completed in the same order.
4. Wait for 20-30 minutes (the length of time depends on dyeing).
5. After the time is up, spray the head with warm water and comb it spontaneously from the root to the tail.
6. Wait 5- 10 minutes before cleaning.
7. This step can also be carried out according to different product requirements.

Question and answer: (8 points for each question, ***5 questions)
1. What is the main reason for the split hair? Short Answer Questions
A: The initial causes of split hair are as follows:
1, because of the imbalance of oil secretion, or the end of the hair shaft where oil can't come out, after a long time, the hair will dry up, yellow and split.
2. Hair can't be well cared for for for a long time, or the knife scissors are unfavorable when cutting (cutting) hair, and the hair tail is excessively damaged, which is also the cause of split ends.
3, improper shampoo method, excessive force at the end of the hair, is also an important reason for the split end of the hair.
4, the shampoo is too alkaline, which is the loss of oil in the hair, plus perming, dyeing, frequent blowing, etc. It is also an important cause of dry hair.
2. What is adjacent color? And scope? Short Answer Questions
A: It refers to adjacent colors. Between adjacent colors, you often have me and I have you. Although they are very different in tone, they are visually similar. All colors within 60 on the color wheel belong to the adjacent color range.
3. What is the difference between negative ion straight hair and free ion straight hair? Short Answer Questions
A: The molecular combination in the hair chain structure is disassembled by amino acids, and then the hair structure is recombined and shaped under the action of specified temperature and materials. Negative ion technology is used in hair styling, which is called negative ion straight hair, and its alkali content is 9. 36 degrees, (electricity is usually 4. 5——6。 About 5 degrees) (9. 0——9。 9-degree hair will break quickly and turn into powder strips) Free radical is an improved product based on negative ions, which minimizes the damage to hair quality and phosphorus surface, and is equipped with free radical formula, which makes the finished hair have the same luster and softness as refined oil, that is, the third dose of free radical repair hydrating agent is combined with the first dose and the second dose in the previous period, and the effect is more ideal.
4. What are the key points of dyeing more than 50% of white hair with primary colors? Short Answer Questions
1. Only 20 volumes of hydrogen peroxide can be used.
Because 20VOL hydrogen peroxide has three characteristics.
A. strong penetration → easier to enter the cortex.
B. The particles are large enough → and the structure of pigment molecules.
C. Good concealment → Because the pigment molecules are large enough, the effect of concealing white hair is better.
According to the situation, you can decide whether to add some enhanced colors to help hide the white hair. 3. It takes less than 4 degrees of hair dye cream formula to cover white hair.
The percentage of white hair is different, and the total number of colors required is also different. The difference of total pigments will affect the coverage of white hair.
Effect, so it is necessary to control the white hair at 50~60% and 80% at 4 degrees; Dye 60 ~ 70% within 2 degrees; Dye 90% within 3.5 degrees; 1 degree internal dyeing.
70~80% is dyed within 3 degrees;
5. Why do you need care after dyeing your hair? Short Answer Questions
Because the hair scales are loose after dyeing, the pigment ions are not completely stable, and it is easy to fade when it comes to shampoo or sunlight and ultraviolet rays. At this time, the inverted film containing color locking factor is used to care for the hair, so that the pigment ions are stable, and at the same time, the luster and elasticity of the dyed hair are increased, making the dyed hair bright and supple.
