Hair Loss in Women

Introduction

  • Hair loss in women is a common condition that can affect the scalp or entire body, resulting from genetic factors, hormonal imbalances, stress, or medical conditions.
  • While some hair loss is normal (50–100 strands daily), excessive shedding or thinning warrants investigation.
  • Effective management involves identifying the underlying cause, lifestyle adjustments, medical treatments, and supportive care.

Types of Hair Loss in Women

  1. Androgenetic Alopecia (Female Pattern Hair Loss)
    • Gradual thinning, primarily on the crown or parting of the scalp.
    • Genetic predisposition plays a key role.
  2. Telogen Effluvium
    • Temporary shedding caused by stress, illness, or hormonal changes.
  3. Alopecia Areata
    • Autoimmune condition leading to patchy hair loss on the scalp or other areas.
  4. Traction Alopecia
    • Caused by hairstyles that pull excessively on the hair (e.g., tight ponytails, braids).
  5. Anagen Effluvium
    • Hair loss during the growth phase, often due to chemotherapy or radiation.
  6. Scarring Alopecia
    • Irreversible hair loss due to scarring from inflammation or injury.

Causes of Hair Loss in Women

  1. Hormonal Imbalances
    • Conditions like polycystic ovary syndrome (PCOS) or menopause.
    • Postpartum hair loss due to hormonal shifts.
  2. Nutritional Deficiencies
    • Lack of iron, zinc, biotin, or protein.
    • Low vitamin D levels.
  3. Medical Conditions
    • Thyroid disorders, autoimmune diseases (e.g., lupus), or chronic illnesses.
  4. Medications
    • Chemotherapy, antidepressants, blood pressure drugs, or hormonal contraceptives.
  5. Stress and Lifestyle Factors
    • Physical or emotional stress.
    • Poor hair care practices or overuse of chemical treatments.
  6. Genetics
    • Family history of androgenetic alopecia.

Symptoms of Hair Loss

  1. Gradual Thinning
    • Reduced hair density, especially on the crown.
  2. Excessive Shedding
    • Clumps of hair in the shower, on pillows, or in brushes.
  3. Patchy Bald Spots
    • Circular or irregular bald areas in alopecia areata.
  4. Widening Part
    • More noticeable in female pattern hair loss.
  5. Broken Hair Strands
    • Common in traction alopecia or damage from styling.

Diagnosis of Hair Loss in Women

  1. Medical History
    • Review of family history, medical conditions, and lifestyle factors.
  2. Physical Examination
    • Scalp analysis to assess hair density, pattern, and presence of scarring.
  3. Blood Tests
    • Evaluate for hormonal imbalances, thyroid dysfunction, anemia, or nutritional deficiencies.
  4. Scalp Biopsy
    • Identifies inflammatory or scarring conditions causing hair loss.
  5. Hair Pull Test
    • Determines the stage of shedding and severity.

Treatment Options for Hair Loss in Women

1. Medications

Minoxidil (Rogaine)

  • FDA-approved for female pattern hair loss.
  • Stimulates hair follicles and increases hair density.

Finasteride or Dutasteride

  • Used off-label for androgenetic alopecia.
  • Blocks dihydrotestosterone (DHT), which contributes to hair thinning.

Spironolactone

  • Anti-androgen medication to reduce hormonal hair loss.

Topical Steroids

  • Reduces inflammation in conditions like alopecia areata.

Iron Supplements

  • Corrects hair loss due to iron deficiency anemia.

Biotin and Other Nutritional Supplements

  • Promotes overall hair health.

2. Non-Medical Treatments

Platelet-Rich Plasma (PRP) Therapy

  • Uses growth factors from the patient’s blood to stimulate hair regrowth.

Low-Level Laser Therapy (LLLT)

  • Enhances hair growth by improving blood flow to the scalp.

Hair Transplant Surgery

  • Transfers hair follicles from one part of the scalp to thinning or balding areas.

3. Lifestyle and Hair Care Adjustments

  • Avoid tight hairstyles to prevent traction alopecia.
  • Use gentle shampoos and conditioners without harsh chemicals.
  • Limit the use of heat styling tools like blow dryers and flat irons.
