People pay a lot of attention to their hair, but there is one thing they miss. That is, healthy hair depends on how healthy the scalp is. Hair grows from the scalp. In most cases, only the visible hair is concerned, but even if you put a lot of effort into the hair while leaving the scalp intact, it is of no use if the scalp is not in good condition. The one thing in common with those who have thick hair, thin and thin hair, thinning hair and hair loss is that the scalp condition is not good.
1. Normal Scalp
A normal scalp has a milky color like this. It is neither dry nor greasy because the oil-moisture balance is well-balanced. The pores are wide open like a volcanic crater, and the inside of the pores is clean. The number of hairs per pore is 2-3. Pore condition and size are very important. The thickness of the hair does not determine the size of the pore, but the condition of the pore determines the condition of the hair. This is because the clearer and larger the pores are, the healthier and thicker the hair grows.
2. Dry Scalp
A healthy scalp has a balance between oil and moisture. A dry scalp lacks moisture. It is characterized by the fact that the scalp is as dry as dry land and covered with dead skin cells and dandruff. Dandruff occurs when dead skin cells are not produced and eliminated normally and accumulate on the scalp. It contains not only dead skin cells, but also sebum, various impurities, and fine dust. Itching is often accompanied by wastes in a dry environment that clog pores and scalp. It is characterized by severe itching and dandruff as it progresses.
* Keratin is the outermost skin tissue of the skin, so keratin itself is not a problem, and various problems occur when it is not circulated normally.
3. Oily Scalp
It occurs when there is too much oil on the scalp. The sebum glands inside the pores produce too much sebum and overflow, filling the pores and scalp with moisture. In severe cases, it travels up the capillaries and makes the hair oily. It often occurs in teenagers who secrete hormones actively. Although it is not as severe as dryness, it can also be accompanied by itchiness and can cause greasy hair due to oiliness.
4. Sensitive Scalp
Sensitive scalp is sensitive to external stimuli and is often red and swollen because the capillaries in the scalp are dilated. Sensitivity can occur as dry or oily scalp worsens, but it is also a scalp problem separate from oily and dry skin because it is a matter of how sensitive the scalp is rather than oil-water balance. Just as skin is sensitive, so is the scalp. The reason why the scalp is more sensitive than the skin is because it is always exposed to strong external stimuli such as UV rays, hair dye, perm, and chemical shampoos used in daily life.

As dry, oily, and sensitive scalp problems become more severe, they most commonly develop into seborrheic dermatitis. When scalp troubles become severe, symptoms such as dandruff, itchiness, rash, and inflammation often appear in combination, making it difficult to define only one condition, so it is also collectively called seborrheic dermatitis. Seborrheic literally means oil flowing, so it is easy to think that it only occurs in oily skin, but in reality, it does not distinguish between oily and dry skin, and it is a condition in which various scalp troubles become more severe and the scalp becomes inflamed and turns red. a lot. In dry seborrheic dermatitis, dead skin cells and by-products are mainly white in color, while in oily seborrheic dermatitis, the areas around the pores are yellow or red like pus. *In cases where the scalp type is not limited to one side and the various symptoms above appear partially or all at once depending on the area, it is called combination scalp.
