I’ve been experiencing hair loss for nearly a year—what should I do?

First, identify the underlying cause of hair loss, then implement targeted treatment. Common causes of hair loss include: 1. **Physiological (normal) hair shedding**: Hair undergoes natural turnover; shedding up to 100 hairs per day is considered normal and does not require treatment. 2. **Androgenetic alopecia (seborrheic alopecia) and alopecia areata**: These conditions require medical evaluation and treatment under a physician’s guidance. Specific anti-androgen medications—such as finasteride and spironolactone—may be prescribed, along with topical hair-regrowth solutions. 3. **Stress-related hair loss**: Excessive mental stress, anxiety, or insomnia can also trigger hair shedding. In such cases, lifestyle adjustments—including stress management, improved sleep hygiene, and adopting healthy daily habits—are essential.
