                                While severe vitamin B5 deficiency is rare, it can sometimes contribute to hair loss or slowed growth. The persistent myth, therefore, that too much vitamin B5 is the cause of hair loss is unfounded, as this essential nutrient is actually beneficial for hair health when consumed appropriately.
