What’s Going On With My Scalp? A Dermatologist’s Guide to Common Scalp Conditions

As dermatologists, we understand that scalp issues can be both discomforting and concerning. The scalp is a unique and sensitive area, and various factors can lead to a wide range of conditions that affect people of all ages. Today, we explore common scalp conditions that impact babies, children, and adults.

Scalp Conditions in Babies and Children

Cradle Cap (Seborrheic Dermatitis): Cradle cap is a common scalp condition among infants. It is characterized by greasy, yellow or brown scales that form on the baby’s scalp, often resembling dandruff. While the exact cause is not fully understood, it’s thought to be related to overactive oil glands and fungal growth. Cradle cap is harmless and usually clears up on its own within a few months. Gentle cleansing and occasionally applying baby oil can help loosen the scales.

Tinea Capitis (Ringworm of the Scalp): This fungal infection can affect children and is highly contagious. It presents as circular patches of hair loss with redness and scaling. The affected areas may also show signs of inflammation and itchiness. Treatment involves antifungal medications, either topical or oral, prescribed by a dermatologist.

Atopic Dermatitis (Eczema): Eczema can affect the scalp in infants and children, causing red, itchy, and inflamed patches. Babies might exhibit symptoms such as crusting, oozing, and thickening of the affected skin. Proper moisturizing and the use of mild, fragrance-free baby shampoos can help manage eczema on the scalp.

Alopecia Areata: This autoimmune condition causes sudden hair loss, often in small, round patches on the scalp. In some cases, it can lead to complete baldness. While the exact cause is unknown, genetics and the immune system play a role. Most people develop it during childhood or their teenage years, and about half will see it resolve on its own within a year without treatment. For others, corticosteroid injections, topical treatments, and in some cases, systemic medications, may be used to manage alopecia areata.

Scalp Conditions in Adults

Dandruff (Seborrheic Dermatitis): Dandruff is a common scalp condition characterized by flaking skin and itching. It’s caused by an overgrowth of yeast on the scalp, leading to inflammation and shedding of skin cells. While dandruff is not typically a serious condition, it can be embarrassing and uncomfortable. Over-the-counter shampoos containing zinc pyrithione, ketoconazole, or salicylic acid can be effective in managing dandruff.

Psoriasis: Psoriasis is a chronic autoimmune condition that can affect the scalp. It leads to the rapid buildup of skin cells, causing thick, red patches covered with silvery scales. Scalp psoriasis can cause itching and discomfort. Treatment options include topical corticosteroids, coal tar shampoos, and phototherapy.

Androgenetic Alopecia (Male and Female Pattern Baldness): This is a common type of hair loss that occurs as a result of a combination of genetic and hormonal factors. In men, it typically leads to receding hairlines and bald spots, while in women, it often results in thinning hair. Over-the-counter minoxidil and prescription finasteride are commonly used treatments for androgenetic alopecia.

Skin Cancer. Basal cell carcinoma, the most common type of skin cancer, can appear as a raised, flesh-colored or pinkish bump on the scalp. It may have visible blood vessels or a central depression. Early detection and removal are crucial for effective treatment. Another type of skin cancer, squamous cell carcinoma, can also develop on the scalp. It often looks like a scaly, red bump or ulcer that may bleed or crust. Regular skin examinations and prompt medical attention are essential.

Scarring Alopecia (Cicatricial Alopecia). Scarring alopecia is a complex and potentially irreversible condition that results in permanent hair loss. Unlike non-scarring alopecia where hair follicles remain intact, scarring alopecia involves the destruction and replacement of hair follicles with scar tissue. This scarring process can be triggered by various factors, including autoimmune diseases, infections, inflammatory disorders, and genetic predisposition. Early diagnosis and intervention are critical in managing scarring alopecia, as treatment aims to halt the progression of the condition and prevent further hair loss. Treatment approaches may include topical or systemic medications to control inflammation, immune-modulating therapies, and occasionally surgical interventions. Since scarring alopecia varies in its underlying causes and presentation, a personalized treatment plan crafted by a dermatologist is essential for optimizing outcomes and preserving the health of the scalp.

General Treatment Approaches:

  • Topical Treatments: Many scalp conditions can be managed with topical treatments such as medicated shampoos, creams, and ointments. These treatments directly target the affected area and can help alleviate symptoms.
  • Oral Medications: For more severe cases or conditions that affect larger areas of the scalp, dermatologists may prescribe oral medications such as antifungals, corticosteroids, or immunosuppressants.
  • Lifestyle Changes: In some cases, lifestyle changes can play a role in managing scalp conditions. For instance, stress reduction techniques, maintaining good hygiene, and avoiding certain hair care products may help.
  • Light Therapy: Phototherapy, or light therapy, can be effective for treating conditions like psoriasis and alopecia areata. Controlled exposure to specific wavelengths of light can help reduce inflammation and encourage healing.
  • Surgical Interventions: Skin cancers on the scalp may require surgical removal. In cases of severe hair loss, hair transplant surgery or other surgical procedures may be considered to restore hair growth.
