Seborrheic Dermatitis
Seborrheic Dermatitis

Seborrheic Dermatitis is a form of eczema that has been linked to the overproduction of sebum and the overgrowth of the microorganism Malassezia. Symptoms of this conditions are exacerbated by heat, illness, irritation, and humid environments. In infants, the condition is referred to as “cradle cap”. At this age, the condition is usually temporary and will resolve itself with the aid of a gentle skincare regimen. However, in adults and teens, seborrheic dermatitis is chronic. Since there is no cure for this in adulthood, the goal of treatment is to control associated symptoms. People of African descent are more likely to develop this condition, making it one of the most common reasons for visits to a dermatologist (American Academy of Dermatology Association, 2022; Skin of Color Society, 2024).


Symptoms

In addition to the yellowish, flaky skin, symptoms can include itching, burning, or a rash that appears pink, purple, or lighter than one’s natural skin tone. Some people may develop a more severe form of seborrheic dermatitis where lesions form around the hairline and results in discoloration (National Eczema Association, 2024).

Diagnosis

A physical examination by a medical professional is usually sufficient to diagnose this condition. The physician will observe the skin on the scalp as well as other parts of the body. If there is an appearance of multiple skin conditions, the physician may suggest a skin biopsy in which a small amount of skin is removed for further examination (Cleveland Clinic, 2020).


Treatment for the Scalp

More often medicated or over-the-counter shampoos are recommended for treating Seborrheic dermatitis and work by reducing the inflammation, targeting the microorganism causing the seborrheic dermatitis or a combination. Over the counter shampoos typically include ingredients such as zinc pyrithone, 1-2% ketoconazole, coal tar, or selenium sulfide. A physician may prescribe an antifungal shampoo with ingredients such as ciclopirox. How often you wash your hair will depend on your hair care regimen, symptoms, and doctor recommendations (Healthline, 2022).




Scalp Care Regimen for Seborrheic Dermatitis

Incorporate a medicated shampoo (e.g. Head and Shoulders, Selsum Blue, T/SAL) into your wash day, and aim to wash your hair once a week if possible. Part the hair and apply the medicated shampoo directly to the scalp. Let sit for at least 5 minutes or as recommended by the product manufacturer or your physician. Subsequently, work the product through the head and rinse out. You can follow up with a moisturizing shampoo, so the hair doesn’t dry out (American Family Physician, 2000). Finally, deep condition or use a leave in conditioner to hydrate the hair shaft. In between washings, use a moisturizer or a light to medium weight oil with anti-inflammatory properties (e.g. sesame seed oil, argan oil) to help protect the hair shaft, prevent brittleness, and control itching and flaking (Lin, T.K, Zhong, L, & Santiago, J.L, 2017).
