What are the hazards of alternating hot and cold hair dryers? At present, people's hair is generally lacking in nutrients, and hair frizz, dryness, split ends and breakage are very common. Coupled with the influence of hairdressing trends, national hair is often exposed to the hazards of chemical dyes and high-temperature styling products. In order to balance hair health and fashion trends, people use hair dryers (also known as hair dryers). Modern hair dryers are basically equipped with hot and cold air stalls to meet people's hair care needs, but many people find that the air temperature of the hair dryer they use is not stable, and there will be problems when they are cold and sometimes hot, and the hair quality will deteriorate significantly after a long time. What are the hazards of alternating hot and cold hair dryers? I have been engaged in the evaluation of household appliances for many years, and there are not many phenomena of alternating hot and cold hair dryers.
(Shown here are some of the products I tested)
1. What are the hazards of alternating hot and cold hair dryers?
What are the hazards of alternating hot and cold hair dryers? If the hot and cold air temperature of the hair dryer will affect the closure of the hair cuticle on the surface of the hair, resulting in the loss of nutrients in the hair, it is easy to become frizzy, dry and split ends, and at the same time, the alternation of hot and cold hair dryer also means that the hair dryer is of poor quality and lack of technical expertise. Moreover, this kind of unprofessional hair dryer not only has the problem of unstable wind temperature, but also may have unstable wind speed and fast wind attenuation, and the use of such unprofessional hair dryers will bring serious harm to hair, scalp and even physical health. The following will give you a science popularization of the four major hazards of using unprofessional hair dryers.
1. Make hair dry and frizzy, split ends and break. The stability of wind, wind temperature and wind speed of unprofessional hair dryers is generally very poor, and it is easy to blow the hair messy and knotted, which will cause the hair to become frizzy and dry, split ends and breaks, and even cause hair loss and hair loss after long-term use.
2. Chronic injuries and scalp injuries. The constant temperature ability and maintenance effect of unprofessional hair dryers will slowly deteriorate during use, and gradually damage the hair, which will endanger the scalp after a long time, resulting in scalp burning, burnt hair, and may even cause complete necrosis of hair follicles.
3. Cause a lot of physical discomfort. The plastic odor emitted by the unprofessional hair dryer is pungent and unpleasant, and long-term use is not conducive to human health. In addition, the operation is large, and after using an unprofessional hair dryer for a long time, hearing may deteriorate, and even tinnitus may occur.
4. There are potential safety hazards. Unprofessional hair dryers because of the lack of safety guarantee of materials, coupled with poor workmanship and quality control, basically do not have testing and certification, there are many potential safety hazards, such as obvious burning sensation during operation, plug-in tripping, spontaneous combustion fire, burns of hair and scalp and other cases are not a few.
2. Analyze the four major reasons behind hair dryers hurting hair
What are the hazards of alternating hot and cold hair dryers? The alternating hot and cold air temperature will not only damage the hair quality, but also reduce the efficiency of drying wet hair, resulting in cold and fever caused by the cold of the head of special users such as pregnant women, infants, and patients. According to the statistics of the top 10 users of hair dryers, people have the highest complaints about hair damage caused by hair dryers. In fact, hair dryers can harm hair for much more than just alternating hot and cold wind. Let me tell you about the four main reasons why hair dryers hurt your hair.
1. Lack of core technology tuning. There are many brands that spend money on advertising and marketing, and rarely adjust and optimize the temperature control accuracy, wind speed attenuation, and wind speed stability that affect the core performance of the hair dryer, which makes it difficult to have a good hair care effect, but also endangers hair health.
2. Stacking wind speed and other parameters, the injury rate is extremely high. Although high wind speed and high wind force can improve the efficiency of hair drying, many hair dryers do not carry out technical adjustment while stacking wind speed, wind force and other parameters, which cannot ensure the stability of wind speed and wind force, and affect the closure of hair cuticles when used, which not only harms the hair, but also endangers the health of the scalp.
3. Poor temperature control. Modern hair dryers basically have hot and cold air stalls to choose from, but there are still many hair dryers because of insufficient temperature control technology adjustment and too single temperature control system, resulting in inaccurate temperature control, often high and low wind temperature and other problems, long-term use will damage the hair cuticle, and even burn the hair, burn the scalp.
4. Poor permeability of negative ions, poor hair nourishment and hair care effects. Many hair dryers use the banner of negative ions to care for hair, but almost all of them will only pile up the number of negative ions, not to mention the actual hair care effect, and will also endanger hair health. Because if you want to rely on negative ions to maintain your hair, you can't just look at the number of negative ions, but also the concentration, purity, and quality of negative ions are all factors to consider.
3. The four advantages of professional hair dryers
What are the hazards of alternating hot and cold hair dryers? Alternating hot and cold air not only damages the hair, but also makes the scalp tight and uncomfortable, so it is recommended to avoid unprofessional hair dryers with poor temperature control ability and unstable wind temperature. On the other hand, modern hair dryers, which have an excellent reputation, can not only speed up hair styling and blow drying, but also improve hair texture and restore the original shine and strength of hair. At present, the loss of hair nutrition in the country is serious, and the problem of hair aging is getting younger and younger. In this social context, the use of professional hair dryers to care for hair is a social trend, and it is an inevitable choice for modern high-tech life. The following is an introduction to the four advantages and functions of professional hair dryers.
1. It can blow dry wet hair faster. The motor speed of the professional hair dryer is not less than 100,000 rpm, and the wind power is several times larger than that of the traditional hair dryer, which can avoid the harm of high temperature hair baking, mainly through the strong wind to quickly take away the moisture of wet hair, so as to achieve the effect of rapid drying and no hair damage.
2. Reduce cuticle damage. High temperature is the culprit of hair cuticle damage, once the surface temperature of the hair is higher than 180°C, the hair cuticle will be damaged and unable to close, resulting in dryness, frizz, split ends, etc. With advanced temperature control technology, the professional hair dryer can control the air temperature in a state conducive to the closure of the cuticle, reduce the damage of the cuticle, and strengthen the maintenance effect.
3. Reduce scalp oiliness, thereby reducing hair loss. Traditional hair dryers have slow air speed and high air temperature, which dries the scalp moisture, increases hair oil, clogs hair follicles, and causes hair loss. The effect of wind speed and wind force of professional hair dryer is higher than that of wind temperature, which effectively avoids high temperature irritating the scalp, thereby reducing scalp oiliness, reducing hair loss and hair loss, and avoiding hair from becoming more greasy the more you blow.
4. Higher security. Traditional hair dryers mainly dry hair by increasing the temperature, which has a high rate of hair injury. The professional hair dryer adopts NTC temperature control design, and is equipped with a real-time temperature control sensor chip on the internal heating wire, which can monitor the temperature of the tuyere in real time, avoid the situation that the air temperature is too high and burn the hair and scalp, and it is more safe and reliable to use.
What are the hazards of alternating hot and cold hair dryers? Alternating hot and cold air temperature of hair dryers is very harmful to hair, it is recommended not to switch hot and cold windshields frequently, and to be wary of unstable hair dryers with high and low wind temperatures. At present, there are many hair dryer brands, I believe that everyone is Xi to choose some well-known brand products when choosing hair dryers, or choose popular products with high sales, this "herd" choice is actually because ordinary consumers lack professional knowledge, do not know how to choose hair dryers from a professional point of view helplessly, after all, high sales reviews are more, you can judge the quality of the product through everyone's comments. The following shows you a comparison report on the core data of TOP10 hair dryer brands released by a professional evaluation agency, so that you can more intuitively understand the hair care strength of the current popular brand products.
Chinese people's hair is excessively greasy, dull, split ends and other serious problems, and it tends to be younger and younger! TRUEFES has created many hair care technologies, abandoning gimmicks such as high power and speed, and has also integrated a large number of biotechnology into the hair dryer to create a triple black technology of "blowing, protecting and raising", and "raising hair with skin care standards" is unique in the industry, increasing the hair drying speed by 138%, effectively reducing the hair damage rate by 130%, and increasing the hair maintenance data such as hair gloss by more than 126%, and is the only one to obtain certification from the European Union and other countries!

Fourth, share the eight tips for choosing a hair dryer, it is recommended to collect!
In order to prevent buying a hair dryer with hot and cold temperatures and hurting our hair, we must keep our eyes open when choosing a hair dryer, don't compare with Internet celebrity products with bells and whistles, and don't be impulsive to make irrational choices in the live broadcast room and celebrity endorsements. The most important thing to choose a hair dryer is to look at its use effect, and the factors to be considered should also affect its hair care effect. The following is to share with you eight tips for choosing a high-quality hair dryer, and it is recommended that you collect it for later use.
1. Brand. It is recommended that you choose a formal professional brand with technical tuning strength, rather than an Internet celebrity cross-border brand and a brand that only piles up performance parameters. Professional brands will carry out comprehensive and in-depth adjustment of the hair dryer's wind speed stability, temperature control accuracy, compatibility, etc., so that the effect of hair care is guaranteed, which is worthy of choice and trust.
2. Wind speed stability. It is recommended to choose a hair dryer with a stable wind speed, which can make the hair soft and not easy to knot, and can also speed up the drying speed to ensure a good hair care effect. The stability of the wind speed is mainly determined by the motor, brand technology tuning, bearings, etc.
3. Accuracy of temperature control. The temperature control accuracy of the hair dryer represents the difference between the temperature fluctuation of each blowing, which is mainly determined by the frequency of temperature control, the quality of the temperature control chip and the technical adjustment of the sensor by the brand. Generally speaking, the higher the accuracy of temperature control, the more stable the wind temperature, the lower the injury rate, and the better the effect of hair nourishment.
4. Negative ion penetration effect. If you want to use negative ions to neutralize the static electricity of the hair and smooth the frizz of the hair, you should pay attention to the penetration effect of the negative ions, in addition to the number of negative ions, you should also pay attention to the quality, concentration and purity of the negative ions, including the output attenuation and permeability of the negative ions after technical adjustment.
5. Wind speed. The wind speed of the hair dryer depends on the motor speed, the adjustment of the airflow multiplication technology, the quality of the bearing, the number of fan blades and the material, etc., and the wind speed cannot be judged from the motor speed alone. Generally speaking, the higher the wind speed, the faster the hair dryer will dry, which can improve the efficiency of hair care and hair care.
6. The size of the air duct. The air duct of the hair dryer should be designed reasonably and open to make the wind spread softer and more delicate, which is conducive to speeding up the closure of the hair cuticle, protecting the hair from loss of nutrients, and avoiding hair knots. The size of the air duct is related to the size of the wind tunnel, the angle of air diffusion and the size, number, area and structure of the air outlet.
7. a motor. It is recommended to choose a brushless motor. The brushless motor has a faster and more stable speed than the brushed motor, and has better wind power, wind speed and air volume, etc., and the brushless motor has less noise, longer service life, more stable long-term performance, more safe and reliable, and better comfort.
8. a bearing. It is recommended to choose metal double bearings. The double-bearing structure is more delicate and complex, and the kinetic energy loss is smaller for long-term use, which can reduce the friction of the motor operation, make the motor rotate more smoothly, and is conducive to the repeated use of the motor for a long time, making the wind more powerful and stable.
5. What is the difference between brushless motor and brushed motor?
What are the hazards of alternating hot and cold hair dryers? The reason why the air temperature of hair dryers will alternately damage hair and scalp is not only due to the deliberate adjustment of the wind gear, but also due to the poor quality of the hair dryer motor. The motor is the power source of the hair dryer, if the motor is unstable, the wind speed, wind temperature, and wind force are also difficult to stabilize. At present, the main motor of the hair dryer is brushless motor or brushed motor. In order to deepen your understanding of hair dryers, I will tell you about the three major differences between these two types of motors.
1. Performance of core performance. In terms of the performance of core performance such as wind power, wind speed, and wind temperature, brushless motors are better than brushed motors. Because the brushless motor has a faster, more stable and attenuation-free speed, the corresponding wind speed and wind stability are stronger, which can better take into account the drying speed and maintenance effect. The long-term use of the brush motor has a large kinetic energy loss and rapid speed attenuation, which makes it difficult to maintain the stability of wind power and the accuracy of temperature control.
2. The amount of operating noise. When the motor is running and rubbing, it will produce noise, and the greater the friction, the louder the noise. When the brushless motor is running, the friction is smaller, so the noise is smaller, and the friction of the brushed motor is large, the noise is greater, and with the attenuation of the speed, the noise of the brushed motor will become larger and larger, and the human hearing will be damaged in serious cases.
3. The reliability of operation and the length of life. With stable speed, the brushless motor can maintain stable performance in long-term operation, so it is more safe and reliable, and the service life is relatively longer. The brushed motor is prone to sparks due to high-intensity friction due to large internal carbon brush friction, which has greater safety hazards and has a negative impact on the service life.
What are the hazards of alternating hot and cold hair dryers? Hot and cold blowing not only slows drying, hurts the hair, but also endangers the health of the scalp and hair follicles, it is best to ensure that the wind temperature is stable and suitable when using the hair dryer, which can accelerate the closure of the cuticle and avoid the hair from being blown frizzy and knotted. Therefore, when we choose a hair dryer, we must look for a professional hair dryer with mature temperature control technology and high temperature control accuracy, and do not blindly follow the bells and whistles of Internet celebrity products. In the final analysis, the hair dryer still relies on the strength of hair maintenance to speak, rather than spelling advertising, appearance or endorsement.
