Correct understanding of hair care, avoiding those IQ taxes


About the big issue of hair care, it is comparable to skin care, and everyone has their own demands.
There is a market for demand, hair conditioner? Hair mask? Hair care essential oil? Different price packages?
Is the value not worth it?
After reading today's content, I believe that you will have your own judgment, and then take everyone to quickly understand

How to "repair" hair care


01
 Basic structure of hair
Each hair consists of a layer of hairy scales (hairy skin), a fur (hair core) and a medulla.
1 hair scale
The hair scales overlap the hair surface in a tile-like manner, usually consisting of 2 to 4 scales. The scales are neatly arranged, so the hair will be bright and moving. Conversely, if the scales are damaged or arched, the hair will lose its luster.
Hair scales are dead cells that cannot be recovered and can only be cured. (So those so-called repair products, you know it is a gimmick)


2 cortical layer
The middle cortex layer accounts for 80% of the hair, usually translucent or colorless, where natural pigments are deposited and hair color is presented.


3 medullary layer
There is some air in the middle of the inner layer of the medulla, which has a certain effect of preventing external overheating.
In addition, the medulla is mainly connected to the scalp hair follicles to maintain hair growth. If the medulla layer shrinks and nutrient transport is difficult, it will cause dislocation.
If the hair is likened to a house, then the scales are tiles, the fur is the pillar frame under the tiles, and the medulla is the energy supply system of the house. Only when the tiles are intact can the house last forever.

 Cause of hair damage


There are many reasons for the damage. There are roughly two types: physical damage and chemical damage.


Physical damage:
1 UV
Strong ultraviolet rays break the chain structure of keratin, which causes the scales to lift up and peel off.


2 Way of combing your hair
After wiping the hair, the way of wiping and the direction of combing are not correct, and the scales are damaged.


3 heating
Use hot curling irons or high temperature hair dryers on wet hair.


Chemical damage:
1 hair dye
The dyeing process is carried out by the polymerization of oxidative dyes inside the hair to form a polymer pigment. This process destroys the internal structure of the hair and causes the scales to become rough and damaged.


When the structure of the hair scale is no longer continuous, it may cause the dye that has entered the hairline to be washed out prematurely, resulting in a dyeing effect that is not durable.


Is there a vicious circle?


2 perm
The perm process has a great damage to the scales, which will break the most sturdy disulfide bond in the fur. The most harmful is the syrup. Many perm lotions in the market contain alkaline components, which have certain oxidation and destruction. The small skin in the hair causes the loss of moisture in the hair.


Because hair is only a product of the body, it is not like our skin can repair itself. Therefore, once the hair is damaged, there is basically no way to repair it. This is irreversible.


So, what can we do to make our hair look better?

How to effectively "repair" hair care


It says that once the hair is damaged, it can't be repaired, which is why it has quotation marks.


For damaged hair, we can only do


1 Make it look good with hair care products
2 protect them from damage


Hair mask, hair conditioner, hair care essential oils or not?
To use.


For damaged hair, they can fill damaged hair to improve the visual tactile state of the hair, anti-static and smooth hair
But they are the same thing, no matter how expensive the main ingredients are positive, silicone oil and moisturizer, but the ratio is slightly different from the specific ingredients.
So, really don’t need to use all the products once, just use one.


Many people ask whether silicon-containing shampoo is good or not?
Silicone oil does create an illusion that hair is very good, but the specific situation is more complicated, and I will write a special content in the future.
The most important thing is that since it has been injured, it will be protected. Don’t hurt it again.
1 sunscreen
Steps where everything is indispensable. You can spray a sunscreen spray every day, or you can use an umbrella or a hat.


2 Avoid combing hair when wet; do not wipe the hair vigorously with a towel. Wrap the hair in a towel and blot the water.
3 Moderate shampooing. For those with dry hair, shampoo should avoid overheated water, because hot water can easily wash off the oil on the skin and scalp, and the skin and hair are easier to dry.


4 When using a hair dryer to blow away from the hair, it can effectively reduce the damage of heat to the hair.


5 Finally, dyed hot, up to once a year, not the best.
