Causes itchy, scaly patches of hair loss.
Contagious and common in children.

Diagnosing Patchy Hair Loss
A proper diagnosis is crucial for effective treatment. Diagnosis typically involves:
Medical History and Physical Examination

A sample from the affected area is cultured to identify the fungus.
Treatment Options for Patchy Hair Loss
Treatment depends on the underlying cause. Here are some common treatments:
Topical Medications
Corticosteroids: Reduce inflammation and immune response in conditions like alopecia areata.

Oral Medications
Corticosteroids or immunosuppressants: For autoimmune-related hair loss.
Antifungal medications: For severe cases of scalp ringworm.
Injectable Treatments
Corticosteroid injections: Directly into the affected area for alopecia areata.
Behavioral Therapy
For trichotillomania, cognitive-behavioral therapy (CBT) can help manage hair-pulling behavior.
Hair Care and Styling
Avoiding hairstyles that put tension on the hair for traction alopecia.
Using gentle hair care products to prevent further damage.
Surgical Options
Hair transplant surgery: For permanent hair loss due to scarring conditions.
Lifestyle and Home Remedies
In addition to medical treatments, certain lifestyle changes and home remedies can support hair health:
Balanced Diet
