Ingrown hair is a common skin condition where hair grows back into the skin instead of rising to the surface¹. This can lead to irritation, redness, and pimple-like bumps. Two related conditions are keratosis pilaris (KP) and pseudofolliculitis barbae (PFB), each with distinct causes and treatments².
Keratosis pilaris
Keratosis Pilaris (KP) is a harmless skin condition where keratin buildup blocks hair follicles, causing small, rough bumps³. It is often genetic and commonly appears on the upper arms, thighs, and cheeks. Exfoliation and moisturizers with glycolic or salicylic acid can help manage symptoms⁴. At BSL Clinic, our medical team utilizes laser treatments to help manage rough skin texture, aiming to refine and smooth the affected area.
Pseudo folliculitis
Pseudofolliculitis Barbae (PFB), or razor bumps, is an inflammatory skin condition caused by hair growing back into the skin after shaving, especially in those with curly or coarse hair. It typically affects the beard area, neck, and sometimes the scalp, underarms, or groin⁵. Treatments include laser hair removal, topical medications, and avoiding close shaving⁶.
