洗发水构成（Shampoo composition）

洗发水构成（Shampoo composition） 洗发水构成(Shampoo composition) 1. shampoo composition Surfactant - the main function is to produce foam, so as to clean the hair. Generally extracted from petroleum, because it is more stable in alkaline environment, so the general shampoo is alkaline. Some weak acid shampoo now is in 1983 Schwarzkopf extract pure plant active agent, sparked a revolution in shampoo. The plant active agent has high cost, but can exist in an acid environment, because the pH value of the shampoo is close to the scalp environment, so the hair can not be damaged, and the cost of the cleaning is higher. Moisture: preferably deionized water, which does not cause deterioration of shampoo, resulting in a lasting shelf life. Spices: contains a lot of shampoo is artificial flavor, the flavor will be deposited in the hair after a considerable period of time, change the original hair special smell, feel not natural. The fragrance of international worship is light, new and natural. Other nutrient supplements - such substances are not susceptible to spoilage in acid environments, and are particularly good for combination with plant active agents. This is the reason for the obvious effect of hair conditioning in today's plants. 2. composition of hair conditioner Active osmotic substance - the main function is to bring nutrients into the damaged parts of the hair. Generally cationic derivatives, because the damaged parts of hair are usually represented by negative charges, so that the positively charged nutrients are attracted positively and automatically to the damaged areas of the hair. Nutrients - the main ingredients of conditioner, such as amino acids, vitamins, B5, and nuclear proteins. This kind of material is not easy to deteriorate in acid environment, so the conditioner or nutrition is acidic. Moisture: preferably deionized water, which does not cause deterioration of shampoo, resulting in a lasting shelf life. Spices: contains a lot of shampoo is artificial flavor, the flavor will be deposited in the hair after a considerable period of time, change the original hair special smell, feel not natural. The fragrance of international worship is light, new and natural. 3. the structure of hair Professional shampoo for each part of the hair to be taken care of. Cuticular layer (hair scale) This layer of hair, if there is a problem, will make the hair knot and bifurcate, surface lack of luster, dry, feel astringent. (glossy shampoo, soft shampoo, water shampoo statement) The cuticle is a kind of keratin, hair cuticle has 20 layers, with scales superimposed, if fall to 10, there will be a lack of luster, at this time due to less damaged hair, so as long as the supplement of some fatty acids and fatty acid water, used to fill pores in water, to enhance gloss effect. Some good shampoo will add horny nails, this material will firmly lock the moisture between the scales, so that the effect is more lasting. After washing, the effect will be smooth, soft and elegant hair. (after shampoo) Cuticle shedding to 5 layer below, hair began to appear at the bifurcation, need more protein to fill the hole, similar to the wax is particularly effective when the protein (protein hydrolysate), because it can cover the surface of damaged hair, make hair smooth and strong is not easy to split, elastic. Long term use, it will gradually solidify the protein covered, and hair formation, a fundamental solution to hair problems. Dermis (cortical layer) When the hair breaks through the epidermis to reach the dermis, the hair will appear porous, dry, knotted, split, broken hair and so on. (damaged shampoo and tail essence after electro dyeing) The dermis is composed of a number of cylindrical cortical fibers (fibers). Hair fiber and hair fiber exist between the hair fiber mesenchyme, the damage to the dermis always starts from the hair fiber stroma (hair fiber is also the most vulnerable to damage). Therefore, it is mainly to replenish the hair fiber stroma. The general use of silica gel to repair, it is like glue or cement more image, make hair fiber tightly split. The hair is then externally coated with the hair wrap to repair the hair. The principle of good nutrition is the same. (after ironing shampoo) Each of the two hair fibers is connected by a chain key, Such as the role of disulfide bond perm. Therefore, some hot shampoo usually contains the sulfur key which is extracted directly from human hair. In addition, this shampoo is very light, not heavy, so that the hot rolls do not lie down because of too much nutrition. This shampoo also has a role is to balance the hair remaining alkaline substances, play a hair conditioning effect. (after coloring locks shampoo) The dermis contains a lot of melanin, artificial colors also stay at this level, so the general color lock are mainly acid washing, blocking the cuticle, outside the pigment in the shampoo is not with the water out (80% fade due to washing). In addition, 20% of the fading is due to the oxidation of the pigment by sunlight and ultraviolet radiation, thus changing the color. Therefore, some shampoos contain antioxidant alcohols (usually extracted from algae). Some shampoo will also add a number of blue pigment in it, because the color of the hair is usually yellow, the use of such shampoo can be yellow hedge, delaying the Yellow effect. Some shampoos contain brightening agents (usually extracted from coconut or palm), which make the color more colorful. And some shampoo...... 4. scalp problems Every hair has an oil glands, it is generally sebum Touyou, excessive secretion of male hormone secretion and hair pomade will result in vigorous growth. Strong oil will bring exuberant, thin hair, dandruff, hair loss bald. And vigorous growth, aging will be rapid, and thus more scarce hair. (balance oil shampoo statement) First remove hair oil, therefore must be strong detergency, washing effect is certainly astringent. Secondly, it is necessary to balance the secretion of oil glands, so that the male hormone back to normal, and normal secretion of oil. Shampoo method: wash every day. (dandruff shampoo.) Food is dandruff Bacillus Touyou, dandruff Bacillus actually everyone's head, just because of the food shortage and slow breeding. Once food is abundant and grows quickly, dandruff can be seen. So there are two ways: one is to go to the oil, and two is to inhibit fungi. General inhibition of fungal products are: miconazole (general use, side effects, easy to lose hair) The soft, sulfur chamber zinc (pure imported formula, the side effect is small.). Shampoo method: wash every day, and then gradually extend the interval. (hair loss shampoo) Anti hair loss non hair shampoo, after use, the effect is usually the number of hair loss gradually reduced until normal. Excessive secretion of pomade, will plug the pores (excessive dandruff will clog pores), severe inflammation. Slight compression of the blood supply to the blood vessel causes thinning of the hair. Until the pressure vessels rupture, completely terminate the supply of nutrients, the formation of alopecia. Therefore, there are two ways: one is to go to the oil, the two is to stimulate the blood circulation, increase the amount of support (usually the use of barbed acid plant essence, such as ginger, onions, garlic, grapefruit, orange and so on). (anti Sensitive Shampoo statement) Usually the scalp is 12 layer, some people scalp only 5 layers, generally open to see the scalp hair Bakai vascular veins. When using chemical products, such people must pay attention to the skin test first, or it is easy to allergies. Anti Sensitive Shampoo should be "no three" products, no artificial flavors, no artificial colors, no alcohol. And its pH should be close to 4.5-5.5 of the scalp. Scalp problems and daily habits A daily habit that causes androgens to increase 1. smoking and drinking; 2. eat fried, fried food (Gao Zhifang); 3. sleep less than 6 hours a day; 4. worried that will not release pressure; 5., irregular work and rest; 6. lack of sports activities; 5.

Rubbing the scalp between the nail and the abdomen is of moderate strength but far away (unless a part of the guest itches and needs a local massage) Bring out the sound. Hair is just passing clean. The hair conditioner protects the hair. While the lack of growth hormone can make the hair growth rate is relatively slow; sex hormones also affect hair fitness: female hormones make hair soft and shiny; male hormone can make the hair become hard and thick, once the hormone is out of balance, it may appear abnormal hair. Therefore, postpartum, menopause, oral contraceptive, in a certain period of time can cause estrogen and alopecia; hypopituitarism, adrenal tumor, acromegaly terminal, which can lead to hair loss. Most women will menopause in alopecia, alopecia confirmed by hormones can indeed, if this is the choice to accept hormonal therapy or prescription medications. 3, disease and drug treatment factors Anemia, malnutrition, acute fever, infectious diseases or chronic liver disease, if the interference of the mother of the hair root hair cell function, growth and color will affect the hair, and even the normal hair cell division was inhibited, leaving the hair in telogen hair loss. In addition, when you suffer from ovarian tumors, you can cause excessive dandruff and greasy hair because of excessive secretion of androgen, leading to seborrheic dermatitis and alopecia. The relationship between drugs and hair Many drugs can damage hair and interfere with beauty.

Other drug treatment factors such as chemotherapy, weight-loss drugs, gastric ulcer medicine, vitamin A acid; as for treatment of cancer chemotherapy, many people know that would lead to hair loss, this is because chemotherapy can kill cancer cells than any rapidly dividing cells, including students in the long-term hair cells, so there will be about 90% hair loss. When the chemotherapy stops, the hair grows back gradually. 4, food and nutrition metabolism factors Due to the partial eclipse caused by the factors of malnutrition, and due to indigestion, chronic wasting disease due to nutritional imbalance or malabsorption, which can lead to the hair growth was inhibited and enter a resting stage, and the appearance of thinning hair, withered, early white or off. Sugar or salt excess, protein deficiency, iron deficiency, zinc deficiency excess selenium, and certain metabolic diseases such as argininosuccinic aciduria, homocystinuria, hereditary orotic aciduria, methionine metabolism disorder, and hair loss causes. The relationship between nutrients and hair Iodine can promote the formation of melanin in the cortex, help the cells to proliferate actively and produce enough melanin. When the iodine deficiency occurs, the hair grows white; Calcium inside the body calcium deficiency, the hair will be excessive thickening, dry and fragile, easy to break; Vitamin deficiency, folic acid, pantothenic acid or B vitamins can cause hair to turn gray; Children with serious protein deficiency, the hair will slowly become red; Zinc deficiency can cause hair loss and baldness; copper, iron, and cobalt can make the hair yellow and turn white. 5, congenital factors Congenital factors such as: caused by developmental defects, various syndromes, such as early aging hair is completely absent or sparse; causing the hair follicle dysplasia valuables easily broken. Congenital alopecia is an autosomal dominant disease, often seen in offspring of consanguineous marriages. 6, physical and chemical factors The relationship between living environment and hair The environment is closely related to hair fitness. In the modern city of smoke and exhaust serious pollution of the living space, resulting in harm to the hair; long-term assignments in the strong sunlight, can cause hair loss of melanin and become dark brown, and cut off the supply of protein in hair, make hair dry. Physical factors such as strain, abrasions, burns and other trauma caused by electrical injury; physical factors including hair alopecia: alopecia, alopecia and mechanical stimulation of local friction alopecia; radiation damage clinically divided into four degrees, which can cause hair loss; excessive exposure to sunlight in the ultraviolet, often use hot hair, hair can become scarce. Because of physical factors caused by hair loss, also known as physical alopecia. Chemical factors, such as boric acid in your shampoo or dye perm, hair cream, hair remover, hair dye and other hair cosmetics are the common causes of hair loss.
