What should you know about small razor bumps?

Ingrown Hairs can create itchy or tender raised spots when a cut hair curves into nearby skin. Pseudofolliculitis Barbae is a recurring form of razor bumps, often in the beard area, where tightly curled hairs re-enter the skin after shaving. Folliculitis can cause follicle-centred red bumps or pus-filled spots and may be triggered by friction, sweat, or microbes. Small rough bumps on the upper arms or thighs may instead fit Keratosis Pilaris, which is not caused by shaving.

Pause shaving the area while it is inflamed. When you resume, soften hair with warm water, use a clean sharp razor, apply shaving gel, shave in the direction of growth with light strokes, and avoid stretching the skin or repeatedly passing over one spot. Rinse, pat dry, and use a bland moisturiser. Do not dig out hairs, squeeze bumps, or share razors. If shaving repeatedly causes problems, a clinician can discuss options such as Laser Hair Removal.

Arrange medical care if bumps become increasingly painful, warm, swollen, or filled with pus, or if redness spreads or fever develops. Seek review for deep lumps, scarring, dark marks that persist, or frequent recurrences despite gentler shaving. Urgent help is appropriate for rapidly spreading redness with severe illness or facial swelling.

Ask whether the bumps are ingrown hairs, folliculitis, or Keratosis Pilaris; which shaving changes fit your hair and skin; and whether a longer-term hair-reduction option is suitable.
