Seborrheic dermatitis is a skin disorder characterized by whitish, greasy or dry scum. Dandruff and squeals are both forms of seborrheic dermatitis. It’s not contagious. The scalp, eyebrows, forehead, face, and nasal grooves are affected. It can also be located on the skin behind the ears, in the external auditory canal, and on the skin of the trunk, especially in the sternum or in the skin folds. Healing requires proper care of the lesions and monitoring of the general state and evolution under medication by a dermatologist.
Signs and symptoms
White scabs appear on the skin, which can detach, leaving reddish spots. The scaffolds are attached to the hair. They can cause itching (itching), but the lesions are usually painless if no infectious complications occur.
Causes of seborrheic dermatitis are unknown.
The risk factors include:
– extremely hot and humid temperature or cold and dry temperature
– rare wash with shampoo
– fatty skin
– other skin conditions, such as rosacea, vulgar acne or psoriasis
– parkinson’s disease
– using alcohol-based lotions that dry the skin
– lack of adequate rest
For diagnosis it is necessary to observe the symptoms of the patients and make the anamnesis and the physical examination by the pediatrician or dermatologist. In the case of children, parents are the ones who have to observe the affection and report it to the dermatologist or pediatrician.
Evolution and complications
Possible complications include:
– social discomfort (embarrassment in public)
– secondary bacterial infection in affected areas
Seborrheic dermatitis is a chronic condition, but it is characterized by long periods of inactivity. During active phases, the symptoms can be controlled with treatment.
Treatment – Home care
Parents or children should use the shampoo for vigorous hair washing daily. The shampoo used is not as important as how you rub the scalp. The crust should be removed with nails while washing with shampoo and scalp for cells for at least 5 minutes.
For low-fat dandruff, non-prescription shampoos and lotions for skin lubrication are recommended. For severe problems we recommend:
– shampoos containing tar or scalp creams containing cortisone; to apply the medication to the scalp, the hair should be split up into the clusters and the ointment or lotion should be applied vigorously through scalp scalp
– topical steroids applied to other affected areas
There are no restrictions in terms of activity. Outdoor activities during the summer can be helpful. No special diet is recommended. You must avoid foods that seem to make the situation worse.
It is allowed to go to school or work.
Specialized medical consultation
Specialist’s advice is required when symptoms of seborrheic dermatitis occur or when seborrhoeic dermatitis lesions have a yellowish yellowing under the crust or leakage of pus, suggesting a superinfection that requires specialized treatment.
