Diffuse alopecia

Diffuse Alopecia

Diffuse alopecia is a condition characterized by widespread hair loss across the scalp. Unlike other forms of alopecia, such as Alopecia Areata or Androgenetic Alopecia, diffuse alopecia does not typically result in complete baldness but rather a general thinning of the hair.

Causes

Diffuse alopecia can be caused by a variety of factors, including:

• Telogen Effluvium: A common cause of diffuse hair loss, often triggered by stress, illness, or hormonal changes. It involves a shift in the hair growth cycle, leading to increased shedding.
• Nutritional Deficiencies: Lack of essential nutrients such as iron, zinc, and vitamins can lead to hair thinning.
• Medications: Certain drugs, including chemotherapy agents, anticoagulants, and beta-blockers, can cause diffuse hair loss as a side effect.
• Systemic Diseases: Conditions like Thyroid Disorders, Lupus, and Diabetes can contribute to diffuse alopecia.
• Infections: Scalp infections or systemic infections can lead to hair loss.

Diagnosis

Diagnosing diffuse alopecia involves a thorough medical history and physical examination. Key diagnostic tools include:

• Blood Tests: To check for nutritional deficiencies, thyroid function, and other systemic conditions.
• Scalp Biopsy: In some cases, a biopsy may be performed to rule out other forms of alopecia.
• Hair Pull Test: A simple test to assess the severity of hair shedding.

Treatment

Treatment for diffuse alopecia depends on the underlying cause:

• Addressing Nutritional Deficiencies: Supplementation with iron, zinc, or vitamins as needed.
• Managing Stress: Techniques such as meditation, exercise, and therapy can help reduce stress-related hair loss.
• Medication Adjustment: If a medication is causing hair loss, a doctor may adjust the dosage or switch to an alternative.
• Topical Treatments: Minoxidil is sometimes used to promote hair growth.

Prognosis

The prognosis for diffuse alopecia varies depending on the cause. In cases of telogen effluvium, hair often regrows once the triggering factor is resolved. However, if the underlying cause is a chronic condition, ongoing management may be necessary.
