Hyperkeratosis Compliance For mild seborrheic dermatitis of the scalp, over-the-counter dandruff shampoos containing selenium sulfide, zinc pyrithione, or coal tar can control symptoms at a fraction of the cost of other treatments.8,9,13 Tea tree oil shampoo may also decrease symptoms.9 For long-term control, antifungal shampoos containing ketoconazole 2% (Nizoral)3,14 or ciclopirox 1% (Loprox)15,16 can be used daily or at least two or three times per week for several weeks, until remission is achieved. Once-weekly use of these medicated shampoos can prevent relapse.14–17 These shampoos should remain on the hair for at least five minutes to guarantee adequate exposure to the scalp.9
Latest news Seborrheic dermatitis is associated with normal levels of Malassezia but an abnormal immune response. Helper T cells, phytohemagglutinin and concanavalin stimulation, and antibody titers are depressed compared with those of control subjects. Zani et al report that even with antifungal treatments, there was no reduction in levels of Malassezia. [23] The contribution of Malassezia species to seborrheic dermatitis may come from its lipase activity—releasing inflammatory free fatty acids—and from its ability to activate the alternative complement pathway.

Seborrheic dermatitis is a clinical diagnosis based on the location and appearance of lesions. In infants, it may present as thick white or yellow greasy scales on the scalp; it is usually benign and resolves spontaneously. In adolescents and adults, seborrheic dermatitis typically presents as flaky, greasy, erythematous patches on the scalp (Figure 1), nasolabial folds (Figure 2), ears, eyebrows (Figures 3 and 4), anterior chest, or upper back.3  The differential diagnosis is lengthy (Table 12,4), but the correct diagnosis can usually be made clinically by the characteristic distribution of lesions and varying course of the disease.5 If the diagnosis is uncertain, a biopsy demonstrating parakeratosis in the epidermis, plugged follicular ostia, and spongiosis can confirm the presence of seborrheic dermatitis. The diagnosis can be challenging in patients with darker skin, but the same principles apply.

What is the treatment for seborrhoeic dermatitis? Stress In general, seborrheic dermatitis is slightly more common in men than in women. Patients with certain diseases that affect the immune system (such as HIV/AIDS and psoriasis) and the nervous system, such as Parkinson’s disease, are also at increased risk of developing seborrheic dermatitis. It can also affect people who have epilepsy, alcoholism, acne, rosacea and mental health issues such as depression and eating disorders.

    Seborrheic dermatitis is a superficial fungal disease of the skin, occurring in areas rich in sebaceous glands. It is thought that an association exists between Malassezia yeasts and seborrheic dermatitis. This may, in part, be due to an abnormal or inflammatory immune response to these yeasts. The azoles represent the largest class of antifungals used in the treatment of this disease to date. In addition to their antifungal properties, some azoles, including bifonazole, itraconazole, and ketoconazole, have demonstrated anti-inflammatory activity, which may be beneficial in alleviating symptoms. Other topical antifungal agents, such as the allylamines (terbinafine), benzylamines (butenafine), hydroxypyridones (ciclopirox), and immunomodulators (pimecrolimus and tacrolimus), have also been effective. In addition, recent studies have revealed that tea tree oil (Melaleuca oil), honey, and cinnamic acid have antifungal activity against Malassezia species, which may be of benefit in the treatment of seborrheic dermatitis. In cases where seborrheic dermatitis is widespread, the use of an oral therapy, such as ketoconazole, itraconazole, and terbinafine, may be preferred. Essentially, antifungal therapy reduces the number of yeasts on the skin, leading to an improvement in seborrheic dermatitis. With a wide availability of preparations, including creams, shampoos, and oral formulations, antifungal agents are safe and effective in the treatment of seborrheic dermatitis.

    Although some doctors warn their patients that any treatment for scalp seborrheic dermatitis may lose its effectiveness after three months of use, a study evaluating a zinc scalp treatment at six and 11 months showed no loss of effect.20 A study of the long-term use of ketoconazole shampoo for maintenance therapy also showed no degradation in effectiveness over time.21 What may appear to be a worsening of symptoms despite continued use of a treatment may actually represent the natural, varying course of the disease. Often, reassurance and maintenance of therapy are all that is needed, reserving changes in treatment for persistent worsening of symptoms. Patients with symptoms that do not respond to any of the therapies outlined above may benefit from systemic anti-inflammatories and should be referred to a dermatologist.
