The weather is getting warmer recently, spring is here, everything is so beautiful! It's just that too much dandruff and itchy scalp have ruined this good mood!
Dandruff is actually a product of scalp metabolism. In addition, the formation of dandruff is also closely related to the imbalance of certain nutrients. In fact, there are many ways to prevent and treat dandruff. By improving our diet, we can achieve the purpose of anti-dandruff when the seasons change.
What is dandruff?
Dandruff is a product of the metabolism of the epidermal cells of our head. Under normal circumstances, when it gradually matures, it will form tiny particles invisible to the naked eye and fall off.
But there will also be abnormal dandruff, which is the "snowflake" we often see, appearing between the hair or falling on the clothes, which is particularly ugly.
Dandruff is also divided into dry and oily, dry dandruff is like snowflakes, the hair is shaken or gently scratched, and the dry dead cells are scaly or flaky, leaving a white snowflake; while oily dandruff is different , it is oily and often sticks to the hair.

Why do head problems often occur this season?
1. Seasonal climate change
The temperature rises in spring, and the growth and metabolism of the human body are obviously accelerated, but the rainy season has not yet arrived. The air is relatively dry, resulting in dry scalp, insufficient moisture in the scalp, easy to dry and crack, resulting in dandruff.
2. The seasonal response of the human body
Humans are mammals, and they also have certain evolutionary characteristics, such as losing weight in summer and gaining weight in autumn and winter. People also have the problem of changing their hair in spring and autumn, and most people have more hair loss in spring and autumn. In fact, it is not just the hair, but also the hair on the body.
How to deal with such changeable seasons?
1. Maintain a clean scalp environment
In spring, microorganisms grow rapidly and allergens are diverse. Those who are prone to allergies must take protective measures when going out, wear masks and hats.
However, long-term blocking is also prone to acne, so go home and clean it in time! Oily hair can wash your hair once a day. And when washing your hair, don't scratch your scalp with your nails, so as not to scratch and cause fungal infection.
2. Light diet
Allergic people should eat less greasy, spicy, irritating food, strong tea, coffee and sweets. Eat more foods rich in vitamins, such as fresh vegetables and fruits, and eat less cold and irritating foods.

The cause of excessive dandruff?
The appearance of dandruff indicates that there are problems in the three major environments of our scalp oil, flora and metabolic balance.
1. Excessive oil secretion
When the scalp oil secretion is unbalanced, excessive oil will be produced, and the hair will become greasy, which will lead to an imbalance of the scalp flora environment, and harmful bacteria will start to breed in large quantities, which will lead to the phenomenon of itchy scalp. Exfoliates to form dandruff.
Abnormal oily scalp not only looks greasy and ugly, but also the oil will accumulate in the hair follicles, hinder cell metabolism, slow down hair growth, and even lead to seborrheic dermatitis and even massive hair loss. Now it's not just dandruff.
About 30% of people have oily scalp. Excessive dyeing and perming can lead to abnormal secretion of sebaceous glands.
2. Fungi
The problem of dandruff is mainly related to the fungus Malassezia that grows on the scalp. Malassezia feeds on sebum, and over-proliferation can lead to dandruff.
After puberty, the human sebaceous glands secrete vigorously, which makes Malassezia on the scalp multiply rapidly, decompose fatty acids produced by oil, and at the same time produce oleic acid, which destroys the protective barrier of the scalp and accumulates dead keratinocytes, thus forming what we call the scalp. crumbs.
3. Other situations
In addition to changes in the scalp, there are many factors in life that can affect hair.
E.g:
Allergies caused by choosing an inappropriate shampoo;
Excessive cleaning can lead to more dandruff and more washing;
Physical discomfort (such as gastrointestinal dysfunction, nutritional disorders, endocrine disorders, etc., resulting in hormone changes in the body);
Spicy diet, excessive tobacco and alcohol will affect the absorption of nutrients, and the absorption of harmful substances will affect the body's metabolism;
Insufficient sleep, often staying up late, affecting skin metabolism;
The formation of dandruff involves many complex factors, such as mental stress, anxiety, high pressure and fast pace.

How to wash hair properly?
1. The water temperature should not be overheated
In winter, everyone likes to wash their hair with hot water, and some people pay attention to "scalping the scalp is comfortable".
But in fact, this method of scalding is not good. Not only will the water vapor and oil on the surface of the scalp evaporate, drying the skin, but also scalding the scalp and hair, resulting in increased oil secretion and more scalp.
2. Use good shampoo
Start by choosing the right shampoo for you, otherwise, dandruff may never get rid of. Of course, a product cannot be used for too long, and the shampoo should be changed regularly.
When using the shampoo, do not squeeze directly onto the hair and rub it, but use your hands to lather and apply it to the hair to avoid irritating the scalp and dandruff.
3. Don’t grab too hard when washing your hair
Especially for people with long nails, when their scalp is itchy, they can't help scratching, and the more they scratch, the more dandruff.
I also like to scratch my scalp when I wash my hair, it feels so comfortable. But this will only make it more itchy, destroy the cells on the scalp surface, or even scratch the scalp, and the dirt from the nails will remain in the wound.
The correct one should be: wash your hair with the pulp of your finger, gently press and rub it in a circle with the pulp of your finger, do not scratch.
