Medical Causes of Hair Loss

Hair loss is a common concern that affects millions of people worldwide. While it is normal to shed some hair daily, excessive hair loss can be distressing and may signify an underlying medical condition. In this blog, we will explore the various medical causes of hair loss, shedding light on the potential triggers and ways to address them effectively.

Androgenetic Alopecia (Male and Female Pattern Baldness)

Androgenetic alopecia, also known as male and female pattern baldness, is one of the most prevalent causes of hair loss. It is typically characterised by a receding hairline in men and diffuse thinning in women. Genetics, hormonal imbalances, and age play significant roles in its development. While androgenetic alopecia is more common in older individuals, it can affect people of all ages. Treatment options include medications like minoxidil and finasteride, as well as hair transplant procedures.

Alopecia Areata

Alopecia areata is an autoimmune disorder in which the immune system mistakenly attacks the hair follicles, leading to patchy hair loss. The condition can occur at any age and may result in complete baldness in extreme cases. Alopecia areata is often accompanied by itching or tingling in the affected areas. Although there is no cure, various treatment options such as corticosteroid injections, topical immunotherapy, and minoxidil can help stimulate hair regrowth.

Telogen Effluvium

Telogen effluvium is a temporary form of hair loss that occurs due to significant physiological or emotional stress. It can be triggered by factors such as pregnancy, childbirth, surgery, severe illness, or psychological stress. Telogen effluvium causes an increased number of hair follicles to enter the resting phase, resulting in excessive shedding. Fortunately, hair usually regrows spontaneously once the underlying cause is addressed or resolved.

Thyroid Disorders

Thyroid disorders, including hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid), can disrupt the normal hair growth cycle. In hypothyroidism, hair may become brittle, dry, and prone to breakage, while hyperthyroidism can lead to excessive hair shedding. Managing the thyroid condition through medication and maintaining hormone balance often helps restore hair growth.

Nutritional Deficiencies

Adequate nutrition is crucial for healthy hair growth. Deficiencies in certain vitamins and minerals, such as iron, zinc, biotin, and vitamin D, can contribute to hair loss. Iron deficiency anaemia, in particular, is associated with hair thinning and increased shedding. A balanced diet, incorporating foods rich in essential nutrients, along with targeted supplementation, can help address these deficiencies and promote hair regrowth.

Scalp Infection

Certain scalp infections, such as ringworm (tinea capitis), can cause hair loss. Ringworm is a fungal infection that affects the scalp, resulting in itchy, scaly patches and patchy hair loss. Prompt medical intervention, usually with antifungal medications, is necessary to eradicate the infection and allow hair to regrow.

Medications and Treatments

Some medications and treatments can have hair loss as a side effect. Chemotherapy drugs, certain antidepressants, blood thinners, and acne medications are known to cause temporary hair loss. Radiation therapy can also result in hair loss in the treated area. In most cases, hair growth resumes after discontinuing the medication or completing the treatment course.

Autoimmune Diseases

Several autoimmune diseases, such as lupus and dermatomyositis, can lead to hair loss. These conditions cause the immune system to attack healthy tissues, including hair follicles. Treating the underlying autoimmune disease with medication and managing its symptoms can help minimise hair loss.
