persistent hair shedding lasting over six months
Chronic Telogen Effluvium (CTE) is a condition characterized by prolonged and excessive hair shedding, typically lasting more than six months. It occurs when a higher than normal number of hair follicles enter the telogen (resting) phase of the hair growth cycle, leading to diffuse thinning across the scalp. This condition can be triggered by various factors, including stress, hormonal changes, nutritional deficiencies, or underlying medical conditions.
