Seborrheic dermatitis and hair loss

An active seborrheic dermatitis flare can cause scale, itching, soreness, and repeated scratching. This can loosen hairs that were ready to shed and can break hairs near the scalp. It does not explain every pattern of hair loss. Smooth patches, a widening part, a receding hairline, broken hairs, scalp pain, or loss of eyebrow hair may point to another condition or more than one process. A clinician can examine the scalp, look at the follicles, and ask when shedding began relative to the flare.

Treat the inflammation as directed, wash gently, and loosen scale with cleansing rather than fingernails. Avoid tight hairstyles, harsh chemical treatments, vigorous brushing, and picking. A medicated shampoo may be part of a scalp plan, while topical treatment can target selected areas. Keep a simple record of shedding, itch, and visible changes, and bring a list of medicines and hair products to the appointment. Do not assume that treating flakes alone will address a separate hair-growth disorder.

Make a dermatology appointment for ongoing shedding, visible thinning, bald patches, or hair loss that continues after the scalp calms. Seek prompt care for painful swelling, pus, marked redness, fever, or a shiny area where follicle openings appear absent. These findings need a closer examination and may require treatment beyond routine dandruff care.

Does the hair loss appear related to inflammation, breakage, or a separate follicle problem? Is the scalp treatment suitable for my hair type? Should I have the thinning examined now rather than waiting for the flare to settle?
