Lesson Content/Board Summary

SCALP DISEASES AND INFECTIONS

Definition of Scalp Diseases

Scalp diseases are various conditions that affect the skin and hair follicles on the head. These conditions can range from minor irritations to severe infections or disorders, often requiring specific treatment.

Common Scalp Infections and Conditions

Ringworm (Tinea Capitis)

Ringworm of the scalp, also known as Tinea Capitis, is a fungal infection that affects the scalp and hair shafts. It is highly contagious and common among children, but it can affect adults too.

The following are common causes of ringworm:

Direct contact with an infected person or animal.
Sharing contaminated items such as combs, brushes, towels, hats, or pillowcases.
Warm and moist environments.

The following are common symptoms of ringworm:

Patches of scaly, red skin on the scalp.
Hair loss in circular or irregular patterns.
Itching and discomfort.
Small black dots on the scalp (broken hair shafts).
Pus-filled sores (kerions) in severe cases.

Tick Bites

Tick bites on the scalp occur when a tick attaches itself to the skin of the head to feed on blood. Ticks can transmit various diseases, making their prompt and safe removal important.

The following are common symptoms of tick bites:

A small, dark bump (the tick itself) attached to the scalp.
Redness and swelling around the bite area.
Itching or mild pain.
In some cases, a rash that develops days or weeks after the bite (e.g., bull’s-eye rash for Lyme disease).

General Scalp Hygiene and Prevention

Maintaining good scalp hygiene is important for preventing scalp diseases and infections.

The following are ways to prevent scalp diseases and infections:

Wash hair regularly with an appropriate shampoo.
Avoid sharing combs, brushes, hats, and other personal items.
Disinfect salon tools and equipment thoroughly after each use.
Inspect clients’ scalps for any signs of infection before providing services.
Keep hair clean and dry, especially after sweating or swimming.
Advise clients to seek medical attention for persistent scalp issues.
