What causes sudden hair loss is a common question for dermatologists and trichologists alike, as hair loss affects up to 50% of women and 40% of men. Hair loss can be a temporary or permanent condition, depending on the underlying cause. Identifying its cause is critical for developing an effective treatment plan.
Many factors contribute to hair loss, including genetics, hormonal changes, medical conditions, certain medications, and hairstyles. Sudden or rapid hair loss, medically known as alopecia, can have numerous causes, such as major stress or illness, a thyroid disorder, or an autoimmune condition.
