Vitamin B12 is the primary active ingredient and supports red blood cell production for oxygen delivery to follicles. Correcting a deficiency in this nutrient is a recognized intervention for certain types of hair shedding.

While the 1000 mcg dose is therapeutic, the profile addresses only a single narrow pathway related to hair health. A more diverse range of nutrients would be required for comprehensive structural or antioxidant follicle support.
