Of the 10,000 ways to make your hair worse, the most common is probably "wrong washing".
Why do others blow their hair smooth and shiny, but you blow it out but you are frizzy and have no hairstyle to speak of? The scales play an important role in this process.
The wrong way of blowing not only hurts the scales, but also slowly destroys the hair. Life Times (search for "LT0385" within WeChat to follow) interviews dermatologists to demonstrate the proper practices of hair care.

The hair texture is damaged, but in fact, the hair scales are injured
The outer layer of hair is covered with hair scales, like the armor of the hair strands, so that moisturizing ingredients, proteins, etc. are not stimulated by the outside world.
Healthy condition of the scales vs. damaged conditions of the scales
If the hair scales are neatly arranged, the hair will appear smooth and shiny; improper protection such as combing hard, blowing or frequent perming and dyeing will damage the hair scales and make the hair lose shine.
How the scales hurt little by little
◎Wet hair state
Hair scales are open when wet, and the friction on the surface of the hair increases, which increases the mechanical damage to the hair fibers. If you comb and rub your hair back and forth, it is easy to cause the upturning and breaking of the small fur scales.
◎Dry hair
When the hair is dry, the hair scales are more susceptible to heat damage. If the hair is blown by a hot wind with a higher temperature, the scales of the fur will no longer cling to the hair, and the moisture will be easily lost, making the hair dry and frizzy.
Do two things before washing your hair
Why is it not recommended to blow dry your hair immediately after washing your hair? To protect the fragile scales, dermatologists recommend that you do two priority "movements".
Use a towel to suck away moisture
It is best to wrap your hair in a thick towel after washing, and it will be better if you have a dry hair cap. Use pressure to allow the towel to suck away moisture from the hair.
Because the hair scales are open when wet, sucking away moisture allows the scales to close.
And after washing hair, vigorously rub your hair with a towel, which many people will have inertial actions, may cause hair damage and make hair texture worse and worse.
Partition before blowing
Divide the hair into three areas: right, left and back, so that each area can be blown in a short time, which is much more efficient.
Data show that sub-regional hair blowing saves 40% of the time compared with random blowing, which can avoid long-term wind blowing and damage to hair quality.
How does a dermatologist blow his hair?
How to use the hair dryer correctly and avoid hair damage? Dermatologists summarize 3 blowing keywords.
temperature
The temperature of the hair dryer is around 57 ° C, which can dry the hair quickly in the shortest time, and at the same time preserve the natural moisture of the hair.
If the hair dryer is equipped with a concentrating head can also be used, it can concentrate the wind and speed up the blow drying of the hair. Use with a comb when blowing wind to make your hair more supple and supple.
distance
Keep a distance when blowing, the hair dryer and the hair root are best kept 10 to 15 cm apart, the air outlet is facing down.
You can blow the scalp first, and then blow the hair. When blowing, shake the hair dryer from time to time to avoid burning sensation in the scalp caused by direct blowing.
Duration
Since the hairstyle, hair volume, and hair length are different, the length of the blow can be judged like this: it is advisable to feel a little wet after blowing the hair.
When the hair is blown to seven or eight minutes dry, use the cold air to slowly blow the hair, so that the hair scales opened by the heat are closed to improve the gloss of the hair.
You can also use hair oil or no-rinse products to keep your hair supple as you blow dry.
After the hair dryer is used, wipe the shell with a clean cloth and store it in a dry place. It is not recommended to use a hair dryer in the bathroom or in a humid space to prevent safety hazards. ▲
