Hair Loss

Hair loss is a widespread issue affecting millions worldwide. Losing up to 100 hairs daily is a normal part of the hair renewal process, but excessive shedding may indicate underlying health concerns. 

What is Hair Loss?

Hair loss, or alopecia, is a condition where hair sheds at a rate exceeding normal, leading to noticeable thinning or baldness. Hair undergoes three main growth phases: anagen (growth, 2–7 years), catagen (transition, 10–14 days), and telogen (resting, 2–3 months). Disruptions to this cycle can trigger excessive hair loss. The condition affects both men and women, manifesting differently based on gender, age, and underlying causes.

Main Causes of Hair Loss

Hair loss can stem from a variety of internal and external factors. The most common causes include:

• Hormonal Imbalances: Conditions like polycystic ovary syndrome, menopause, pregnancy, or hormonal medications can lead to hair loss. In men, androgenetic alopecia is linked to heightened sensitivity of hair follicles to dihydrotestosterone.

• Genetic Predisposition: Androgenetic alopecia, affecting up to 80% of men and 50% of women, is often hereditary.

• Stress and Psychological Factors: Chronic stress or intense emotional trauma can cause telogen effluvium, resulting in diffuse hair thinning across the scalp.

• Medical Conditions and Medications: Endocrine disorders (e.g., thyroid issues), infections, autoimmune diseases (e.g., lupus, seborrheic dermatitis), and chemotherapy can lead to temporary or permanent hair loss.

• Nutritional Deficiencies: Lack of iron, zinc, vitamins D, B12, or biotin can weaken hair follicles.

• External Factors: Frequent use of hair dryers, flat irons, tight hairstyles, chemical treatments, or poor environmental conditions can damage hair structure.

Symptoms of Hair Loss

The primary sign of alopecia is losing more than 100 hairs daily. Other symptoms include:

• Clumps of hair on brushes, pillows, or in the shower drain.

• Visible thinning at the crown, temples, or frontal area.

• Itching, flaking, or excessive scalp oiliness.

• Brittle, dry, or dull hair.

• Receding hairline or patches of baldness.

Types of alopecia vary by pattern:

• Androgenetic: In men, a receding hairline; in women, thinning at the parting.

• Diffuse: Uniform thinning across the scalp.

• Focal (Alopecia Areata): Localized bald patches, sometimes affecting eyebrows or eyelashes.

Diagnosis and Treatment

Consulting a trichologist or dermatologist is essential to pinpoint the cause of hair loss. Diagnostic methods include:

• Medical history review (past illnesses, medications, stress).

• Blood tests to check hormones, vitamins, iron, and inflammation markers.

• Trichoscopy, examining the scalp and hair under a microscope.

Treatment is tailored to the individual and may involve:

• Medications: Minoxidil and finasteride (for men) promote hair growth. Hormonal imbalances may require corrective drugs.

• Injectable Treatments: Mesotherapy and platelet-rich plasma (PRP) therapy nourish hair follicles.

• Physiotherapy: Laser therapy, darsonvalization, and scalp massage improve blood circulation.

• Surgical Options: Hair transplantation is used for irreversible alopecia.

• Hair Care: Specialized shampoos, avoiding harsh treatments, and a balanced diet support hair health.

Preventing Hair Loss

To prevent alopecia, consider:

• Maintaining a nutrient-rich diet high in proteins, vitamins, and minerals.

• Managing stress and ensuring adequate sleep.

• Protecting hair from cold, heat, and aggressive styling.

• Regular medical checkups to detect underlying conditions early.

Conclusion

Hair loss is not just a cosmetic concern but a medical issue requiring timely intervention. Early consultation with a specialist, thorough diagnostics, and personalized treatment can halt alopecia and restore hair health. Addressing symptoms promptly and prioritizing overall wellness are key to maintaining vibrant hair.
