Seborrheic dermatitis of the scalp

Speaking of head diseases such as seborrheic dermatitis, I believe everyone is familiar with them. Because the sebaceous glands in the skin can secrete sebum, which is one of the more normal physiological functions. However, if the sebaceous glands are hyperactive, the sebum secretion will gradually increase, which can easily lead to various chronic skin inflammations. So what are the clinical manifestations of seborrheic dermatitis on the head?

In fact, seborrheic dermatitis of the head is a chronic skin disease. In addition to occurring mostly on the skin on the top of the head, it can also appear on our face, nose, and other places and parts of the body. So what is the main cause of seborrheic dermatitis on the head?

Seborrheic dermatitis of the scalp

The head is where there are many sebaceous glands. The secretion of sebum by the sebaceous glands of the skin is a normal physiological function. However, if the sebaceous glands are hyperactive, too much sebum will be secreted and accumulate on the skin, and chronic skin inflammation will occur at the accumulation site. Seborrheic dermatitis of the scalp refers to a disease that occurs on the scalp and begins as mildly erythematous patches covered with grayish-white bran-like scales, accompanied by mild itching. As the rash expands, greasy, scaly, map-like patches may become visible. The symptoms of seborrheic dermatitis on the scalp are mica-like white scaly patches on the scalp, which are large and diffuse, scattered like stars on the scalp or hairline. The scales fall off when you grab them with your hands.

It is a chronic disease with easy recurrence, often accompanied by folliculitis and blepharitis. The face is often complicated by acne and rosacea mite dermatitis. The most fundamental and effective way to treat seborrheic dermatitis is to use Kangfu Anti-Sebum Ointment to inhibit abnormal sebum secretion, reduce the inflammatory response in the skin lesions, thoroughly detoxify and prevent the release of histamine and histamine receptors, thereby playing an antipruritic role. The scalp starts with mild erythema patches covered with grayish white bran-like scales, accompanied by mild itching. As the rash expands, greasy scaly map-like patches may appear. In severe cases, there is exudation, thick crusts, and a foul odor, and the entire scalp may be invaded. Hair may fall out and become thin.

Causes

① Inflammation causes the normal bacteria already present on the skin (such as Pityrosporum) to multiply and invade the skin. ② The increased amount of sebum breaks down into free fatty acids through the action of Propionibacterium acnes and other bacteria, which irritate the skin. ③ Excessive mental stress, eating habits, vitamin B deficiency, alcoholism, etc. can also cause the occurrence of seborrheic dermatitis.

Everyone already knows about the symptoms and causes of seborrheic dermatitis on the head. In fact, the symptoms of this type of disease are quite obvious. In addition to redness and patches on the scalp, there will also be white bran-like scales, and even varying degrees of itching. Therefore, if such symptoms occur, do not be afraid to seek medical treatment. Timely treatment is the most important thing.
