Hair Infections
What Are Hair & Scalp Infections?
These are conditions caused by microorganisms (fungi, bacteria, viruses, or parasites) that affect the scalp, hair follicles, or hair shafts. If untreated, they can lead to hair thinning, breakage, or even permanent hair loss.
What's Included
Common Infections & Their Symptoms
- Tinea Capitis: Fungal infection causing round, scaly bald patches. Often itchy and contagious.
- Folliculitis: Inflamed or infected follicles with red bumps, pus, and itching.
- Seborrheic Dermatitis: Greasy scales, flaking, and itchy red scalp (often mistaken for dandruff).
- Impetigo: Crusted bacterial infection with golden-yellow sores.
- Head Lice (Pediculosis): Intense itching with visible lice or nits on hair strands.
Diagnosis Methods
- Scalp examination under magnification (trichoscopy)
- Fungal culture or swab test
- Wood’s lamp (UV) test for fungal glow
- Skin biopsy in severe or unclear cases
