Alopecia is the medical term for partial or complete hair loss, most commonly affecting the scalp. It can occur suddenly or gradually, appear in patches or diffusely, and may be temporary or permanent depending on the underlying cause. Common types include androgenetic alopecia (pattern baldness), alopecia areata (patchy, autoimmune-related loss), and telogen effluvium (stress- or illness-related shedding).
Because hair loss can stem from many different causes—hormones, genetics, autoimmune conditions, nutritional deficiencies, medications, or stress—identifying the specific type of alopecia is essential to finding the right treatment. Rather than guessing, take a free, instant, online symptom check to help clarify possible causes and guide your next steps with confidence.
