Seborrheic dermatitis is a chronic papular and scaly superficial inflammatory skin disease that occurs in areas where sebum is secreted. It is often accompanied by varying degrees of itching and commonly affects areas with abundant sebaceous glands, such as the head, face, and trunk. The disease is chronic and may recur periodically. Treatment generally includes three aspects: Firstly, patients should be informed to maintain a regular lifestyle, get sufficient sleep, avoid various mechanical irritations, use less hot water and strongly alkaline soaps for bathing, and pay attention to their diet. They should try to reduce or limit the intake of polysaccharides, alcohol, and spicy foods, while consuming more vegetables and fruits. Secondly, topical medications are used, generally choosing formulations that contain corticosteroids and antifungal agents, such as compound miconazole and compound econazole. If the response is inadequate, calcineurin inhibitors such as tacrolimus and pimecrolimus can be used. Zinc oxide ointment, boric acid and zinc oxide camphor ointment, and erythromycin ointment can be used when there are exuding erosions. If the scalp is affected, shampoos containing ketoconazole or selenium sulfide may be used. Thirdly, oral medication treatments typically include supplementation with B vitamins such as vitamin B2, B6, complex B vitamins, or zinc-containing formulations. For severe itching, antihistamines can be taken orally. Oral itraconazole may be used for fungal infections or widespread lesions. Tetracycline or erythromycin may be used for bacterial infections.

Seborrheic dermatitis is caused by what?

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic papular squamous superficial inflammatory skin disease that occurs in areas with excessive sebum secretion. It can be accompanied by varying degrees of itching and is commonly found on the scalp, face, chest, and back where sebaceous glands are abundant. Both adults and newborns are frequently affected. The exact causes of this condition are not yet fully understood. Currently, it is generally believed to be related to an increase in sebum secretion or changes in its chemical composition. Additionally, colonization and infection by Malassezia fungi, along with factors such as stress, diet, vitamin B group deficiency, and alcohol consumption, can all influence the occurrence and development of this disease to varying degrees.

How to completely cure seborrheic dermatitis of the scalp?

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic, superficial inflammatory skin disease characterized by papular scaly rashes, predominantly occurring in areas rich in sebaceous glands such as the head, face, and trunk. The exact cause of this disease is still not fully understood. It is mainly believed to be related to an increase in sebum secretion or changes in its chemical composition. Additionally, colonization and infection by Malassezia yeast, along with factors like stress, diet, deficiency in B vitamins, and alcohol consumption can all influence the occurrence and development of this condition to varying degrees. Due to these factors, the disease has a chronic course and may relapse repeatedly. Seborrheic dermatitis occurring on the scalp, although clinically curable, can still experience flare-ups. Its symptoms mainly include oily hair, scalp papules, erythema, dandruff, and itching. Clinical treatment primarily involves the use of shampoos containing ketoconazole, selenium sulfide, or salicylic acid. This can be accompanied by oral antihistamines, supplementation with B vitamins, or zinc-containing preparations. It is crucial to maintain regular life habits, ensure sufficient sleep, restrict diets high in polysaccharides and fats, increase the consumption of vegetables and fruits, avoid alcohol and spicy irritant foods, use less hot water and strongly alkaline soaps for bathing, and avoid various types of mechanical irritation to reduce the recurrence of scalp seborrheic dermatitis.

Will seborrheic dermatitis recur?

Seborrheic dermatitis is likely to recur. In cases of seborrheic dermatitis, oily skin can easily lead to recurrence. Additionally, an inappropriate diet, often consisting of spicy, irritating food, as well as fried and greasy food, and habitual late nights, can also easily lead to recurrence. Therefore, when seborrheic dermatitis occurs, it’s essential to maintain a light diet, avoiding spicy and irritating foods, and seek treatment under the guidance of a doctor. For topical use, one can choose corticosteroid medications, typically choices include desonide ointment or hydrocortisone butyrate cream. For oral medications, options include Vitamin B6 or a B-complex vitamin. If itching is significant, it might also be necessary to combine treatment with antihistamine medications.

What are the symptoms of seborrheic dermatitis?

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic, superficial inflammatory skin disease characterized by papular and scaly inflammation that occurs in areas of sebum secretion. It can be associated with varying degrees of itching and is commonly seen in adults and newborns. The main symptoms include hair follicle papules appearing in areas of sebum secretion such as the scalp, face, chest, and back, which then merge into dark red or yellow-red patches. These patches are covered with greasy scales and crusts, which can lead to exudation, crusting, and erosion, manifesting eczematous changes. In severe cases, the lesions can spread throughout the body, leading to diffuse erythema and significant desquamation. At this stage, it is referred to as seborrheic erythroderma. This condition is chronic and may have recurrent episodes.
