An ingrown hair occurs when a cut follicle curls sideways and penetrates the surrounding skin wall, sparking localized inflammation. While common on the firmer skin of the pubic mound, they can be intensely painful when they form on the scrotum.
If a red, tender bump appears, leave it alone. Do not squeeze, puncture, or pick at it with tweezers. Puncturing the skin introduces common skin flora like Staphylococcus aureus into deep tissue layers, risking severe localized abscesses. Instead, apply a warm, damp compress to the area for 10 minutes twice a day to soften the keratin plug.
Apply a low-concentration chemical exfoliant containing salicylic acid (0.5% to 1%) or lactic acid to the base of the hair every other day. Chemical exfoliants dissolve dead skin cells without the abrasive damage caused by physical loofahs or rough scrubs. If an inflamed spot displays spreading redness, systemic warmth, or persistent discharge, consult a physician promptly.
