What should you know about folliculitis due to shaving?

A razor can create tiny areas of irritation, especially when it is dull, used repeatedly over the same patch, or pushed firmly against the skin. Hair cut very close may curl back into the skin and cause an ingrown hair. Sweat, friction, thick products, and bacteria on grooming equipment can add to the problem. The result may be small follicle-centred bumps, itching, burning, tenderness, or pustules.

Shaving-related folliculitis can affect the beard, neck, underarms, legs, chest, or pubic area. Acne, eczema, and other rashes can look similar, so ongoing or unusual changes should be examined.

Let the skin settle before shaving again. When you resume, soften hair with warm water, use a clean sharp razor and a suitable shaving gel, and shave in the direction of growth with light strokes. Avoid stretching the skin or repeatedly passing over one spot. Rinse the blade, let it dry, and do not share it. If bumps continue, a clinician can discuss an alternative hair-removal method or prescribed topical treatment.

See a clinician if the bumps persist after stopping shaving, recur each time, spread beyond shaved skin, drain, or leave scars or lasting colour changes. Prompt care is needed for fever, rapidly expanding redness, severe pain, a deep swelling, or red streaking. These signs can indicate infection that needs more than routine grooming changes.

Ask whether the bumps are folliculitis, ingrown hairs, or another rash. Discuss razor technique, suitable products, alternative hair removal, and whether a topical or oral treatment is appropriate for the findings.
