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.

Similarly, there is little to no good evidence to suggest that "hair formula" supplements work, such as Viviscal (which includes marine protein), Hair La Vie Clinical Formula, and Nutrafol products.
