Scabs on My Scalp: Causes, Symptoms, and Treatment

Scabs on the scalp are often caused by dryness, which damages the natural barrier protected by your sebaceous glands. This can result in dry and itchy scalp.

14 Possible Causes of Scalp Scabs

Dry scalp: Excessive hair washing, high mineral content in water, hot showers, harsh shampoos, and high heat treatments can lead to scabs.
Oily scalp: Excess oil can cause irritation, scratching, and scabbing.
Dandruff (seborrheic dermatitis): Itchy white flaky patches at the hair follicles can lead to scabs.
Contact dermatitis: Allergic reaction from hair product changes or environmental toxins can cause dry scab patches on the scalp.
Psoriasis: Silver or white scabs with severe itching may occur due to this skin condition.
Lice: Itching and scabbing can result from lice infestation.
Ringworm: Fungal infection causing red, scaly skin with extreme itching and potential hair loss.
Eosinophilic folliculitis: Itchy sores filled with pus that later form scabs, commonly seen in individuals with HIV/AIDS.
Seborrheic eczema: Small bumps, thick red scabs, and swelling leading to itching may be caused by this condition.
Shingles (herpes): Scabbing on the scalp is a common symptom of this viral infection.
Lichen planopilaris or lichen planus: This serious condition may cause red bumps, scabs, scarring, and hair loss on the scalp.
Poisoning: Heavy metal poisoning can be a possible cause.
Diet: Nutritional deficiencies, especially protein, may affect scalp health.
Burns: Burns and other injuries can result in damaged hair shafts and scabs.

Symptoms of Scalp Scabs

Scabs appear as crusty raised areas on the scalp, often yellowish but can range in color. They cause excessive dryness around them, leading to:

Burning or itching sensation
Dried blood with or without pus formation
Hair loss
Flaking or crusting skin
Bumps, blisters, or sores
Bad odor

A scab is the skin’s natural healing response to an injury or scratch. However, constant scratching damages the skin and can lead to inflammation, scarring, and bald patches.

Treatment for Scalp Scabs

The best approach is to avoid scratching the scabs to allow them to heal within 10-14 days. Over-the-counter shampoos and medications can help, but consulting a doctor is recommended for appropriate treatment.

Home remedies to soothe the scalp include:

Hydrating scalp mask
Warm compress
Serums with urea and ceramides
Warm oil massage with coconut, jojoba, or tea tree oil
Natural ingredients with antioxidants and antimicrobial properties such as aloe vera gel, lemon juice, neem leaves, apple cider vinegar, oatmeal, cocoa butter, and sea salt

Your dermatologist may prescribe antimicrobials, antihistamines, or steroids depending on the severity and underlying cause.
