Hair loss manifests in various forms, such as thinning, excessive shedding, or patchy bald spots. It can stem from numerous causes, including hormonal imbalances, nutritional deficiencies, stress, medication side effects, or underlying medical conditions like thyroid disease or autoimmune disorders. Hair loss often carries a significant psychological impact, affecting self-esteem and body image, making it vital to address both the physical and emotional aspects of this condition.
