Understanding Hair Loss and Its Causes

Causes of Hair Loss - Dermstetiq Clinic Singapore

Hair loss can be an unexpected guest, arriving unannounced and overstaying its welcome. Whether you’re noticing your hair thinning or discovering more strands on your pillow, understanding the root causes of hair loss is the first step to addressing it effectively. In this article, we’ll delve into the various causes of hair loss, explore how it affects both men and women, and discuss the medical investigations involved in diagnosing its underlying causes.

The Many Causes of Hair Loss

Hair loss can stem from a variety of sources, including genetics, medical conditions, and external factors. Knowing the cause is essential for effective treatment.

Genetic Predisposition

  • Male Pattern Baldness (Androgenetic Alopecia): This is the most common form of hair loss in men, characterized by a receding hairline and thinning on the crown. It’s inherited through family genes.
  • Female Pattern Baldness: For women, hair loss can present as general thinning around the part and the crown, retaining the frontal hairline.

 

Health-Related Causes

  • Hormonal Imbalance: Conditions like polycystic ovarian syndrome (PCOS) or thyroid dysfunction can lead to hair loss.
  • Stress and Trauma: Physical or emotional stress can shock hair follicles into a resting phase, leading to temporary hair shedding known as telogen effluvium.
  • Medical Conditions: Diseases such as diabetes and lupus can contribute to hair thinning. Chemotherapy is a well-known cause of temporary hair loss due to its impact on dividing cells.

 

Environmental Factors and Lifestyle

  • Diet and Nutrition: A deficiency in nutrients such as iron, zinc, and vitamins can impact hair health.
  • Hair Treatments and Styling: Frequent use of dyes, bleaches, and heated styling tools can damage hair and result in breakage.

Differing Types of Hair Loss in Men and Women

The manifestations of hair loss differ between genders due to hormonal and genetic factors. Understanding these differences can aid in diagnosing and treating the condition effectively.

In Men

  • Pattern and Progression: Male pattern baldness often begins with a receding hairline followed by thinning at the crown. Over time, these areas may expand, leading to complete baldness.
  • Hormonal Influence: Dihydrotestosterone (DHT), a derivative of testosterone, is a significant player in male hair loss, affecting the hair follicle’s growth cycle.

 

In Women

  • Less Predictable Patterns: Women’s hair thinning tends to be more diffuse, affecting the top of the head and part line.
  • Postpartum Hair Loss: After childbirth, many women experience shedding due to falling estrogen levels, although it typically resolves within a few months.
  • Impact of Menopause: Hormonal changes during menopause can also trigger hair thinning.

Investigating Hair Loss: Tests and Diagnosis

Diagnosing the root cause of hair loss often involves a comprehensive medical examination, including blood tests to identify any underlying health issues.

Essential Blood Tests

  • Thyroid Panel: Evaluates thyroid function, as hormones produced by the thyroid gland are vital for normal hair growth.
  • Complete Blood Count (CBC): Assesses overall health and can indicate infections or medical conditions like anemia.
  • Iron Levels (Ferritin): Checks for iron deficiency, which is a common cause of hair loss in women.
  • Hormonal Tests: Measures the levels of hormones such as testosterone, estrogen, and cortisol.

 

Other Diagnostic Approaches

  • Scalp Biopsy: This involves removing a small section of the scalp tissue to examine hair follicles and diagnose conditions like alopecia areata or cicatricial alopecia.
  • Hair Pull Test: A simple test where the doctor gently pulls on hair strands to determine if excessive shedding is occurring.

Conclusion

Hair loss is a complex issue with many potential causes, types, and solutions. Understanding the underlying cause of your hair loss is vital in determining the best approach to managing it. By exploring genetic predispositions, health conditions, and lifestyle factors, as well as seeking medical advice when necessary, you can better navigate the journey of hair loss.
