Loss of eyebrows, complete, unilateral or bilateral

Loss of eyebrows, complete, unilateral or bilateral

Loss of eyebrows, whether complete, unilateral (affecting one eyebrow), or bilateral (affecting both eyebrows), refers to the absence or significant reduction of hair in the eyebrow region. It can have various causes and may be a cosmetic concern for individuals affected by this condition.

Causes

The causes of loss of eyebrows include:

Alopecia Areata

An autoimmune condition where the body's immune system mistakenly attacks the hair follicles, resulting in hair loss, including the eyebrows.

Trauma or Injury 

Severe trauma or injury to the eyebrow area, such as burns, accidents, or surgical procedures, can damage the hair follicles and lead to eyebrow loss.

Aging

As individuals age, hair growth in various areas of the body, including the eyebrows, may naturally decrease. Thinning or loss of eyebrows can occur as part of the aging process.

Medical Treatments

Some medical treatments like chemotherapy, radiation therapy, or certain medications can cause temporary hair loss, including eyebrow loss. Once the treatment is completed, hair growth usually resumes.

Trichotillomania

A psychological disorder characterized by an irresistible urge to pull out one's hair. In cases where individuals compulsively pull out their eyebrow hairs, it can lead to significant eyebrow loss.

Symptoms 

Signs and symptoms of loss of eyebrows include: 

• Absence or thinning of eyebrow hair.
• Sparse or patchy appearance of the eyebrows.
• Altered facial appearance or symmetry.
• Emotional distress or self-consciousness about the eyebrow loss.
• Difficulty applying makeup or shaping the eyebrows.

Diagnosis

Following tests and exams are conducted to diagnose loss of eyebrows:

Medical History

The healthcare provider will inquire about the onset, duration, and progression of eyebrow loss, as well as any relevant medical conditions or treatments.

Physical Examination

A thorough examination of the eyebrows and surrounding areas will be conducted to assess the extent of hair loss and identify any underlying skin conditions or abnormalities.

Blood Tests

Blood tests may be performed to evaluate hormone levels, thyroid function, and markers of autoimmune conditions, as these can be associated with eyebrow loss.

Skin Biopsy

In certain cases, a small sample of skin from the eyebrow area may be taken for biopsy to rule out specific skin conditions that can cause hair loss.

Consultation with a Dermatologist

If the underlying cause of eyebrow loss is not apparent, a referral to a dermatologist may be made for further evaluation and specialized testing.
