As the seasons change, the temperature difference between day and night also becomes larger, and the transitional season arrives as well. To adapt to changes in the external environment, the human body ends up using more energy than usual.

In addition, when the weather becomes dry, our body loses its balance of oil and moisture, and various minor and major problems can occur. These problems do not appear only on the skin, but can also affect the scalp and hair.

In addition to what was mentioned above, environmental factors such as air pollutants like fine dust, yellow dust, and pollen can cause dandruff or dead skin cells, block pores, reduce scalp health, and make natural hair thinner.

If that happens, the hair can fall out easily, and this issue can lead to the loss of natural hair. Moreover, we need to pay attention so that it does not develop into a more serious situation by making efforts such as maintaining basic cleanliness and supplying an appropriate oil-moisture balance. In this article, let’s talk about what happens if you don’t wash your hair and hair loss.

However, some people say that after washing, the balance of oil and moisture is disrupted, which can instead cause healthy hair to fall out. Some of you may wonder whether hair loss does not occur if you don’t wash your hair, but symptoms can actually become worse when hair is washed frequently.

We have probably experienced seeing countless strands collected in the drain after washing. Also, each time this happens, looking at the many strands on our fingers can make us think that a lot of hair is falling out during washing.

Seeing this may make you worry or feel mental stress, but this phenomenon is one part of the natural shedding process caused by the hair growth cycle and is unrelated to how often shampoo is used. About 60 to 80 hairs can fall out in a day, and the hairs that should have already been shed, or that had already come loose, may have simply been tangled together while you were not washing, so they only come off and appear on your hands during cleansing. In a normal natural-hair condition, this can be seen as the growth phase and the resting phase.

Generally, these two periods repeat and hair grows. During the growth phase, hair may only be shed if it is subjected to a force strong enough to lift an object weighing about 70 g or more, but during the resting phase, it can be easily pulled out with only about 20 g of force. Therefore, when going through this resting phase, washing once or twice a day can help maintain cleanliness rather than requiring special treatment.

If you don’t wash your hair for a long time, setting aside the issue of hair loss, the first thing that happens is a buildup of waste and an unpleasant odor. The hair becomes oily, and in addition to dandruff and sebum, various kinds of dust also stick to the sticky surface of the natural hair. Waste that has accumulated on the scalp can cause itching, and if you are seen scratching with your fingernails because of unbearable itchiness, it may give others a bad impression, which can in fact negatively affect your social life. In addition, it is said that this can cause not only appearance-related issues but also the condition itself, and may even lead to seborrheic scalp dermatitis.

When this condition develops, small red spots become more prominent and the itching also becomes worse. It is a disease that can commonly occur in people of all ages and genders, from children to adults, and if detected early, the symptoms can be improved easily. However, even if these symptoms and problems are present, you should know that together with hair loss from not washing your hair, dermatitis that starts on the scalp can spread to the face, chest, and back.

In addition, if seborrheic scalp dermatitis, a skin lesion with a yellow, greasy, scale-like form on reddish patches caused by severe scratching, has worsened and spread here and there, it is highly likely that the condition has already become quite severe. In that case, the itching becomes extremely severe to the point that it is hard to endure, and even if it has worsened, the possibility of it developing into hair loss from not washing your hair becomes even higher.

If you keep scratching the affected area because of itching, it can cause wounds, and bacteria can enter those wounds and cause reinfection, creating a vicious cycle that repeats continuously. In today’s environment, where living conditions are relatively well maintained, cases that develop this severely are not common, but if such a condition does appear, it is important to alleviate it through proper treatment at an early stage.

Because not washing your hair can cause hair loss and various other conditions, it is best to always maintain and manage cleanliness to prevent this, and it is also important to learn the correct way to wash your hair and follow it properly. When shampooing, it is good to keep the process within about 5 to 10 minutes, and sometimes people leave cleansing products on for longer than the recommended time, which is not the right method.

This is because chemical ingredients such as surfactants contained in the product can irritate the skin if they remain in contact with it for a long time, and for people with sensitive skin, this can worsen scalp health. It is also helpful to give enough time to rinse the hair, and if you take a bath before going to bed and then sleep without drying your hair properly so it can dry naturally, you create a damp and humid environment that is good for the growth of fungi and bacteria. This can trigger various conditions such as the seborrheic scalp dermatitis and fungal dandruff mentioned earlier, so please keep in mind that you must allow enough time to dry your hair completely.
