Sudden Hair Loss? Dermatologist Highlights Conditions to Watch

Sudden hair loss or thinning can be alarming and may indicate significant underlying health issues. While it is common for hair to shed as part of its natural growth cycle, excessive hair loss can be a sign of conditions such as alopecia. This disorder affects millions globally each year and can occur at any age, often related to genetic factors, lifestyle habits, or other health conditions.

In a recent interview with HT Lifestyle, Dr. Amrutha Hosalli Karjol, a consultant and chief dermatologist at Vrudhii Skin Center and Surgery Clinic in Bengaluru, emphasized the importance of recognizing sudden changes in hair health. She noted, “While some hair shedding is normal, sudden or excessive hair fall can be distressing and may indicate the need for medical attention. Early recognition and timely management are crucial in preventing long-term damage to hair follicles and restoring confidence.”

Conditions Triggering Sudden Hair Loss

Certain medical conditions can exacerbate or trigger alopecia. Dr. Karjol outlined three common causes that require immediate attention:

1. Hormonal Imbalances and Endocrine Disorders
Hormonal fluctuations, especially those associated with thyroid disorders or conditions like Polycystic Ovary Syndrome (PCOS), can disrupt the hair growth cycle. In women, increased levels of androgens may weaken hair follicles, leading to noticeable thinning at the crown or a widening hair part.

2. Autoimmune and Inflammatory Conditions
Autoimmune diseases, such as alopecia areata and lupus, can cause the immune system to attack healthy hair follicles. This often results in sudden, patchy hair loss affecting the scalp, beard, or other areas of the body. Additionally, inflammation from conditions like seborrheic dermatitis or psoriasis may aggravate hair loss.

3. Post-Illness and Nutritional Deficiencies
Severe illnesses, high fevers, or post-viral conditions—including COVID-19—can lead to a condition known as telogen effluvium, where hair prematurely enters the shedding phase. Furthermore, inadequate intake of essential nutrients, including proteins, iron, and vitamin D, can weaken hair structure, increasing its susceptibility to breakage and loss.

Dr. Karjol advocates for awareness of these factors to prompt timely consultations with healthcare providers.

Seeking Medical Advice

If you are experiencing sudden hair loss, it is crucial not to overlook these symptoms. Consulting with a dermatologist can provide clarity and a tailored approach to treatment. While some hair loss may be benign, understanding the potential medical causes can facilitate early intervention, ultimately preserving hair health and enhancing personal well-being.
