Alopecia : Causes, Risk Factors, Symptoms, Treatment


Alopecia refers to hair loss that can occur anywhere on the body, but most commonly affects the scalp. It can result from various factors, including autoimmune disorders (like alopecia areata), hormonal changes, genetics, or medical treatments such as chemotherapy. Alopecia presents as bald patches or complete hair loss, impacting both men and women. Treatment options vary depending on the type and cause of alopecia, ranging from medications to hair transplants. The condition can have significant emotional effects due to its visible nature and potential societal perceptions.

Symptoms of Alopecia

If you suspect you or someone else is experiencing Alopecia, it is crucial to seek immediate medical attention by calling emergency services or consult with a Dermatologist.


  • Androgenetic Alopecia: Also known as male-pattern or female-pattern baldness, it is the most common cause, influenced by genetics and hormones.
  • Alopecia Areata: An autoimmune condition where the immune system attacks hair follicles, leading to sudden hair loss.
  • Telogen Effluvium: Triggered by stress, illness, or hormonal changes, causing a large number of hair follicles to enter the resting phase simultaneously.
  • Traction Alopecia: Hair loss due to constant pulling or tension on the hair follicles, often from hairstyles like tight ponytails or braids.
  • Trichotillomania: A psychological disorder where individuals have an irresistible urge to pull out their hair.
  • Chemotherapy and Radiation: Cancer treatments can cause hair loss by damaging hair follicles, though hair may grow back after treatment.
  • Nutritional Deficiencies: Inadequate intake of certain nutrients like iron, zinc, or vitamins can contribute to hair loss.
  • Medical Conditions: Certain diseases such as thyroid disorders, lupus, and diabetes can lead to alopecia.
  • Medications: Some drugs used for arthritis, depression, heart problems, and high blood pressure can cause hair loss as a side effect.
  • Infections: Fungal infections of the scalp (such as ringworm) can cause hair loss if left untreated.

Risk Factors

  • Genetics: Family history plays a significant role, as alopecia often runs in families.
  • Autoimmune Conditions: Disorders like rheumatoid arthritis, lupus, or thyroid diseases increase susceptibility.
  • Age: Alopecia areata often begins in childhood or early adulthood, while male and female pattern baldness typically develops with age.
  • Hormonal Changes: Imbalances such as during pregnancy, childbirth, or menopause can trigger hair loss.
  • Medical Treatments: Chemotherapy and radiation therapy used in cancer treatment commonly lead to hair loss.
  • Stress: Emotional or physical stress can contribute to temporary hair loss.
  • Hair Practices: Excessive hairstyling (e.g., tight ponytails, braids) or treatments (e.g., frequent dyeing, heat styling) can damage hair follicles.
  • Nutritional Deficiencies: Inadequate intake of certain nutrients, like iron or protein, may affect hair health.
  • Environmental Factors: Exposure to pollutants or toxins can impact hair growth.
  • Medications: Certain drugs used for arthritis, depression, heart problems, etc., list hair loss as a potential side effect.


Hair Loss: Alopecia causes hair loss, typically in small, round patches on the scalp. This hair loss can progress to total baldness (alopecia totalis) or complete loss of body hair (alopecia universalis).
Patchy Bald Spots: The most common symptom is the appearance of smooth, round bald spots on the scalp. These spots are usually coin-sized initially but can enlarge over time.
Gradual Thinning: Some people may experience a gradual thinning of hair rather than distinct bald patches.
Changes in Nail Appearance: In some cases, alopecia areata can affect the nails, causing them to become pitted or ridged.
Sudden Hair Loss: Hair loss can occur suddenly and may be noticeable during periods of stress or illness.
Regrowth: Hair may grow back in one area while another bald patch develops elsewhere.
Itching or Discomfort: Some individuals may experience mild itching or discomfort in the affected areas.
Emotional Impact: Alopecia can have significant psychological effects, leading to anxiety, depression, or low self-esteem.

Trichoscopy: Using a handheld dermoscope to examine hair shafts and scalp for characteristic features like miniaturization or broken hairs.
Scalp Biopsy: Obtaining deeper tissue samples if scarring alopecia is suspected, aiding in precise diagnosis.
Phototrichogram: Quantifying hair density and growth rates through microscopic analysis of plucked hairs.
Diagnostic Imaging: MRI or ultrasound to evaluate underlying structures in cases of suspected traction or scarring alopecia.
Psychological Assessment: Addressing emotional impact and stressors, integral in managing alopecia.

Frequently Asked Questions
Alopecia is a medical term used to describe hair loss. It can occur in various forms, such as alopecia areata (patchy hair loss), androgenetic alopecia (pattern baldness), or even totalis or universalis (complete hair loss on the scalp or entire body).
The exact cause of alopecia is still unknown, but it is believed to be an autoimmune disorder where the immune system mistakenly attacks the hair follicles. Other factors like genetics, hormonal changes, and certain medical conditions may also contribute to its development.
Currently, there is no known cure for alopecia. However, various treatment options are available that can help manage and slow down the progression of hair loss. These include medications, topical treatments, injections, and even surgical procedures like hair transplantation.
While stress alone may not directly cause alopecia, it can trigger or worsen existing cases of hair loss in individuals who are genetically predisposed to it. Managing stress levels through relaxation techniques and self-care practices may help in reducing its impact on the condition.
The regrowth of hair depends on the type of alopecia experienced. In some cases of patchy hair loss (alopecia areata), spontaneous regrowth may occur without treatment within a few months to a year. However, for more severe forms like totalis or universalis, regrowth may be less likely.
