What should you know about folliculitis and hair loss?

Inflammation around a hair follicle can make hairs shed from an affected area or break because the skin is sore and scratched. Pustules, crusting, itch, tenderness, and small areas of reduced density may occur. Hair loss can also have separate causes, including pattern hair loss, autoimmune disease, scalp infection, traction, or irritation from products. The timing and appearance help distinguish these possibilities.

Temporary shedding is different from scarring hair loss. Shiny skin, a smooth patch without visible follicle openings, persistent pain, or spreading inflammation may signal damage that needs timely assessment. Do not assume that every area of shedding is caused by folliculitis.

Avoid scratching, picking crusts, tight hairstyles, harsh chemical treatments, shaving over inflamed skin, and fragranced or irritating products. Wash gently with a suitable cleanser, rinse well, and dry without rubbing. Use clean pillowcases, towels, brushes, and hats, and avoid sharing them. Take clear photographs in consistent lighting so changes in density, redness, or crusting can be described at an appointment.

A clinician may recommend treatment aimed at inflammation, infection, or another scalp disorder. Do not use leftover antibiotics or apply strong scalp medicines without guidance. If hair loss started after a new medicine, illness, procedure, or intense stress, include that timing in your history.

Arrange dermatology review for persistent shedding, expanding patches, recurrent pustules, scalp tenderness, crusting, or visible thinning after the inflammation settles. Seek prompt care for rapidly spreading redness, severe pain, fever, facial swelling, or pus with feeling unwell. Earlier assessment is useful when the skin looks smooth or scarred, because some forms of follicle damage can progress without much discomfort.

Ask whether the loss appears temporary or scarring, whether the scalp needs testing, and which cleansing, medicine, or hair-care changes are appropriate. Mention the first day of bumps and shedding, affected sites, tight styles, chemical treatments, new products or medicines, family hair history, itch, pain, crusting, and photographs showing progression.
