Supplements for Hair Loss -- woman looking at hairbrush


Deficiencies in nutrients such as iron, zinc, biotin, vitamin D and protein can cause hair loss. Supplementing to offset these may reverse this hair loss. However, supplementing with these nutrients is unlikely to benefit people who already get adequate amounts.
