Ever wondered: why with the same shampoo, other people's hair is always so smooth, while yours is frizzy and forked?
In fact, not only because of genetics, even if two people with the same hair quality, the habit of washing and blowing hair is likely to produce different results.
And many people's methods are used incorrectly!
So what kind of shampoo and hair blowing method is correct?
If you want to explain how to wash and blow your hair, you must first get to know our old friend, the hair strands.
When the hair is observed with the naked eye, it is a thin line, but in fact, its structure is still very complicated when zoomed in. From the inside out, they are the myeloid, the cortical, and the fur, the latter two of which are what we often call the hair core and the hair scales [1].
In this structure, the most important thing is the hair scales.
To look good, you first need to protect the scales.
If the scales are relatively intact, without defects, and closed tightly, the hair will look shiny; conversely, if the scales are defective and not tightly closed, the hair will look dry and dull.
A characteristic of the hair scale is that it will open when it meets water, and it will close again when it is dry.
Knowing this characteristic of hair, it is easy to understand the correct posture of washing and blowing hair.

When washing the hair, the hair scales on the hair open in contact with water, and if you rub and rub hard, it is bound to wear out the open hair scales, and even split the hair from the open hair scales in two to form a fork.
Therefore, if you want to have a haircut, the key to washing your hair is to move gently and wash your hair along the scales.
There may be a small partner will ask, can this be washed clean?
Many people have a misconception about washing their hair: washing their hair is washing the hair on their heads.
But the hair is not as dirty as you think, and the essence of washing hair is: wash the scalp!

Wash off oil and secretions from the scalp and hair near the scalp with shampoo.
Dust from your hair is completely removable when flushing, and you don't need to rub it hard.
So when washing hair, massage the scalp with your fingertips, and finally rinse gently along the hair, which can be completely washed clean and not hurt the hair.
In the same way, you can't rub your hair vigorously when you are drying, and it is okay to press and rub along the scales. Dry your hair until it no longer drips.
Read more about the medical code:
It is true that studies have shown that it is better to dry hair naturally than to blow it with a hair dryer, because when the hair is dried naturally, its fur and fur cortex are simultaneously contracted.
And with the hair dryer drying, the outer layer of fur skin dried relatively fast, the inner hair medulla, fur cortex dried more slowly, easy to form the internal and external pressure difference, the elasticity of the fur skin decreased, so the hair at this time is easy to break [2].

But this is too unfriendly for girls with long hair, and the long hair at the waist wants to dry naturally, and I am afraid that I will have to wait until the flowers are thanked.
Especially if you take a bath before going to bed at night, it is very bad to fall asleep with wet hair, not only is it easy to catch a cold, but the wet hair rubs with the movement of the head when sleeping, but it is even worse for the hair quality.

So in order to save dry hair time, you can use a hair dryer to blow your hair. But there are a few important points to note:
1. Order: blow dry the root of the hair first, and then blow the tail.
Many people like to blow the wettest hair tail first, in fact, this kind of blowing is not only time-consuming, but also health risks. Blow dry the hair root first, mainly you can blow dry the scalp first, prevent the cold, but also prevent the head from being affected by the wind caused by migraine, while the hair water is dripping from top to bottom, close to the hair root is better to blow dry, saving time.

2, distance: the hair dryer should be as far away from the hair as possible.
At temperatures above 50°C, the likelihood of thermal breakage rises linearly [2].
In view of the different brands and models of hair dryers can achieve different temperatures and wind, so when blowing the wind should follow the principle of "blowing out the wind does not burn the skin", in addition to lowering the temperature, the hair dryer and the hair to maintain a certain distance, can effectively prevent the scalp from being burned, to prevent hair high temperature damage.

3. Direction: Blow in the direction of hair growth.
Blowing in the direction of the scales helps the hairy scales to close, so that the hair blown out is smooth and not easy to knot.
4, time: according to the amount of hair, the hair blows until the hair is all separated, and there is still a hint of wetness when it feels.
According to personal needs, after the hot air blows, you can turn to the cold air to continue blowing until it is completely dry, or you can wait for the hair to dry naturally.

The details of washing your hair, wiping your hair, and blowing your hair are all done right, and after sticking with it for a while, you believe that your hair texture can already crush most people.
If you want to go to the next level on this basis, you can also work hard in these places:
1, reduce the frequency of perm dyeing: frequent perm dyeing will not only damage the hair scales, but also may hurt the hair core, the damage to the hair is extremely large.
2. Use conditioner or hair mask when shampooing: Conditioner and hair mask can help the hair scales to close, increase the lubrication effect, prevent hair knots, and facilitate hair straightening. The composition and function of the two are relatively close, and everyone can choose according to their own needs. (Ps: can only be used in the lower part of the hair, oh, do not use on the scalp)

3, daily use of hair care essential oil: unlike skin care and hair mask, hair care essential oil can not be washed off, apply to the hair tail before going out during the day, can make the hair tail more tough, not easy to age.
