The hair loss package is a set of laboratory tests specifically designed to investigate the most common nutritional and hormonal causes of non-hereditary hair loss. The package focuses on assessing the body's nutritional status by measuring essential vitamins and minerals for hair follicle growth and health, as well as ruling out anemia as a primary cause. It specifically targets deficiencies in iron (and its stores), zinc, vitamin D, and vitamin B12, any deficiency of which is linked to hair loss and thinning.
