What are the disadvantages of hot blow drying? Disadvantages of blowing hair

If the temperature is too high, blowing your hair will cause your hair to be drier and more prone to dullness, yellowing and breakage.

Because the hair cuticle is open when the hair is wet, too hot wind will damage the hair cuticle, resulting in dry and frizzy hair, and the scalp is dehydrated and oily.

The appliance itself has battery radiation. It is easy to have headaches after blowing for a long time, and it is easy to lead to hair loss and other problems.

High temperature will make the hair very frizzy, and it is easy to turn yellow after a long time, you can use a Leven hair dryer, which has intelligent thermostatic technology.

If used incorrectly, it will blow the moisture out of your hair. If the moisture content of the hair is reduced to less than 10%, the hair strands will become rough and split ends.

It is easy to burn out the hair dryer.

When the moisture content in the hair is less than 10%, the hair will become very dry and coarse, and it is prone to split ends.

Personnel damage the hair, it is recommended not to blow too dry.

Blowing hair at high temperatures can cause thermal degradation of the hair, and the surface temperature of the hair is too high, which will lead to the decomposition of the hair chromophore and the damage and even scorching of the hair fibers. High temperatures can cause a large number of thermal fractures in the cuticles, and combing at high temperatures can lead to a large number of cuticle loss. Unlike traditional hair dryers, the Laifen high-speed hair dryer does not dry quickly by high temperature, but by high-speed wind and large air volume.

Even if the Leifen high-speed hair dryer only has a rated power of 1600W, it can still rely on blowing several times the airflow to dry hair quickly. This is all thanks to the use of a patented air pressure multiplication technology, which allows the air around the air outlet to join the dry train with a strong negative pressure.

Blowing your hair often is going to be.

Damage to the hair, but there are certain prerequisites for this.

The following requirements will be met during use before damage to the hair will be caused.

1. The temperature is too high.

Dry your hair with a hair dryer after shampooing, as high temperatures will destroy the proteins in your hair, making your hair too dry and more prone to breakage.

2. The distance is too close.

When blowing hair, if the distance between the hair dryer and the hair is too close, the temperature will be too high, which will not only damage the hair, but also cause some damage to the scalp.

3. Blow dry immediately.

It is generally recommended to dry your hair with a towel after washing it, and then blow it with a hair dryer until it dries when it does not drip. Otherwise, blowing for too long will also cause damage to the hair. Also, when towel drying, don't rub it too much, as this will make your hair dry and split ends.

The harm of hair dryer blowing hair is obvious, many people are used to using a hair dryer to dry their hair after washing their hair at home, but if they are not used properly, the moisture in their hair will be blown away. If the moisture content of the hair is reduced to less than 10%, the hair strands will become coarse and split ends, which is the consequence of using a hair dryer to blow your hair regularly.

Wrong method: After shampooing, there are not a few people who carelessly use a hair dryer to blow their hair, and it is a kind of destruction for the hair. We know that it's this hot air and dryness that hurts the hair.

Correct method: Ideal for natural dry hair after shampooing. You can also use a towel to dry your hair until it dries for 7 or 8 minutes, and then use a hair dryer to blow your hair at a distance of 20-25 cm.

If used incorrectly, it will blow the moisture out of your hair. If the moisture content of the hair is reduced to less than 10%, the hair strands will become coarse and split ends, and using a hair dryer to blow your hair regularly may make your hair bad, such as rough, yellow, split ends, and even hair loss.

Use the hair dryer correctly.

1. Blow the roots first.

Don't blow on the ends of your hair first, the water that penetrates the roots will make you useless. Blow dry the roots first, then the ends, or let the ends air dry to minimize damage from the hair dryer.

2. Pay attention to the number of power.

Low-powered hair dryers use high temperatures to scorch the hair, evaporating the moisture from the hair, and the hair becomes even drier. The high-power hair dryer uses a large amount of wind to pass through the hair to remove moisture, which can quickly dry the hair and minimize damage.

3. Keep a distance between the hair dryer and the scalp.

Keep the hair dryer about 15cm away from your hair and avoid letting it touch your hair, as getting too close can cause heat damage to your hair.

4. When blowing your hair, you should choose the angle.

For long hair, use the technique of full mouth ventilation, and for short hair or near the root of the hair, use the technique of half mouth. When blowing, keep a distance of about 10 cm between the air outlet and the hair, and at the same time use your fingers to smooth the hair while blowing, taking care not to let the hot air stay on one part of the hair for too long; In addition, the cuticle of wet hair is open, blowing in the direction of hair growth will make the cuticle close, if you blow backwards, the cuticle will open, and the more you blow, the more frizzy it becomes.

5. Pay attention to the direction of blowing.

If you want to blow silky hair, remember to blow the hair dryer in the direction of the cuticle. The cuticle grows and closes in the direction of the hair tip, which means that your hair dryer will blow the hair from top to bottom, and the reverse blowing will make the hair open and the hair feel rough to the touch. Conversely, if you want to have voluminous hair, bend down and pull all your hair forward, then use a hair dryer to blow it backwards, and comb it with a flat comb to double the volume of your hair in no time!

Wet hair is the most fragile, and it's best not to touch it, let alone blow it with a hair dryer! It won't be long before your hair will be severely dry, split ends, and prone to breakage, and your hair will become frizzy and difficult to take care of The best way is to dry it naturally Of course, if you already have the above problems in your hair, the first thing to do is to cut off the split ends and then polish regularly, preferably once a month Usually use a shampoo that separates the shampoo Choose your own brand This is more conducive to the maintenance of your hair Then don't comb your hair with a plastic or nylon comb, preferably a boxwood comb, The mahogany comb is also good

Many people believe that blowing their hair can damage their hair, while hairstylists believe that it is necessary to dry hair with a hair dryer after each hair wash, but pay attention to the method, angle, and extent of blowing. Blowing hair will hurt the hair is actually a misunderstanding, every time you don't blow your hair after washing your hair, the wet hair roots are more likely to stick to dust and other substances, if you use a towel instead of blowing hair, it is more likely to hurt your hair, because the hair is the most fragile when it is wet, you can't dry it hard, and you can't shake your hair desperately with a towel, otherwise your hair will break or knot. The correct way is to wrap the absorbent towel to absorb the hair dripping, when the hair is no longer dripping, hold the hair dryer high, raise your hand over your head to dry the hair vertically, as long as you let the hair dryer keep moving, and pay attention to keep the distance from the hair above 10 cm, the hair dryer will not hurt the hair, and the hair can be blown to seven to eight percent dry.

After washing the hair, let it air dry naturally, and it is not advisable to use a hair dryer to dry it, so as to avoid weakening the elasticity of the hair and causing hair breakage.

Many people are accustomed to using a hair dryer to dry their hair after washing their hair at home, but if it is not used properly, it will blow the moisture out of the hair. It is said that if the moisture content of the hair is reduced to less than 10%, the hair strands will become rough and split ends, and this is the consequence of using a hair dryer to blow your hair regularly.

Look at the specific frequency, generally two or three days to blow is no problem, before the hair was blown out of a bunch and very dry, so annoying, I feel that the temperature of the hair dryer is too high or what, and then it was planted by Xiaohongshu into the roller like a torch, it is a negative ion hair dryer, and it is a constant temperature! It doesn't hurt the hair, but the drying speed is not slower than the general hair dryer, it's magical, I carefully read some of the product introductions under a cat to know that this not only has negative ions but also bioceramics seem to be called, can be kept at a constant temperature without hurting the scalp, the main appearance is also very good-looking, I like it, I recommend this.

There are two harms of hair dryers: 1, it is harmful to hair, 2, it is close to the head for a long time when used, and electromagnetic radiation is harmful to human health.

Many people don't expect that the amount of radiation produced when a hair dryer is running is one of the highest among household appliances.

The reporter chose a 1000W hair dryer. After turning it on, the display jumps all the way to the back end of the hair dryer: 87mg 144mg 356mg 411mg, and finally hovers between 340 and 360mg (mg milligrams are the units of magnetic field strength used to calculate the amount of low-frequency electromagnetic radiation in this study by the Shanghai Institute of Family Planning Sciences).

However, as the distance increases, the radiation decays rapidly. The "little black box" was moved 5 centimeters behind it, and the radiation dose dropped to 10 milligrams at about 10 centimeters.

The test found that the safety factor of the hair dryer outlet was much higher. At a distance of 3 centimeters from the air outlet, the amount of low-frequency radiation is, and a little farther away, about 8 10 centimeters, which is the distance at which we usually blow our hair, the amount of radiation here is only.

In fact, in daily life, the probability of being close to the back end of the hair dryer is almost zero. Even in the barber shop, with the hair dryer in the next seat facing you, the distance must be much greater than 10 centimeters.

Frequent use of a hair dryer to keep the hair in contact with hotter temperatures will cause certain damage to the protective film of the hair layer. But if you blow your hair on a lower temperature every time, it's better, but the disadvantage is that the shape is poor. It takes longer to blow dry.

I don't think it's a problem with the hair dryer, it's a problem with the temperature, some hair dryers are too high in temperature to damage the hair is very serious, but *** will not, this straightforward high-speed hair dryer is very good, the temperature is suitable and will not cause damage to the hair, the cost performance is also high, this one recommended by friends around me, not bad.

Hair dryer coming.

It is a large radiation source, before the test of self-sufficient, low-grade, high-grade;

Later, a detailed test was done on different parts of the hair dryer when the hot air stall was opened, and the handle was meters, t; Air outlet, it seems that the hair dryer is really to be used less.

Magnetic radiation is divided into two levels, in which the unit of power frequency band is t, if the radiation above t is strong radiation, there is a certain harm to the human body, and long-term exposure is prone to leukemia. If the radiation is below, it is relatively safe. Whereas, the unit of radio frequency electromagnetic waves is w 2. ）

Damage to hair! It will make your hair very dry! The tail end is easy to fork! And it will turn yellow!

There is a skill in using a hair dryer If it is just for drying, it is best not to use hot air, a good hair dryer can hit the cold air, and then blow it from the roots to ensure that the roots of the hair are dry. And if it is for hairstyling, you need to use hot air, as long as it is well maintained, the hair dryer will not hurt.

Hair will not absorb enough moisture.

It will become dry and frizzy.

Not good, because it is used often.

BAI hair dryer causes hair loss.

Zhi a lot of moisture, make.

DAO hair is dry, yellow, brittle, if the fruit is used up, especially if the hair is dry, the best use of conditioner hair dryer can be used, but correct use will reduce the damage to the hair.

1. Dry the washed hair with a dry towel as much as possible, but do not rub it 2. Alternately blow hot and cold air, at this time, the hair dryer is about 20 cm away from the hair 3. Blow halfway, stop, comb the hair, and then blow again.

4. Don't blow anymore when the blow is eighty percent dry, at this time, comb your hair and wait for it to dry naturally.

5. That's it.

The above is what I usually learn about the use of hair dryers in some magazines, I hope it will be useful to you.

Especially with hot air, "hair is easy to break" and "water loss, if you are really in a hurry, it is better to use cold air! It's best to just do it naturally.

Wake up early (you can wash it at night) and damage your hair! It's going to get dry and frizzy! Easy to yellow!

It's not good to wash your hair in the morning, because you don't dry it thoroughly and go out!

If you blow your hair with a hair dryer often, it will make your hair drier and lose a lot of nutrients.

So it is recommended to blow it a little, or wipe it with a dry towel until it is 7-8 dry, and let it dry naturally!

1. Hair dryer blowing hair will hurt hair quality:

When the moisture content in the hair is as low as 10%, the hair will become very dry and rough, and it is easy to split ends.

2. Hair dryer blowing hair will have radiation hazards:

The hair dryer emits the most radiation when it is turned on and off, and the more power the hair dryer has, the more radiation it emits. The asbestos fiber particles contained in the hot air of the hair dryer are very harmful to pregnant women.

3. There will be safety risks when blowing hair with a hair dryer:

The quality of some hair dryers is not guaranteed, and the use of such hair dryers not only damages people's hair, but also harms people's bodies in serious cases. When its temperature increases, it may emit fireballs.
