Can = yes.: Whether or not a vitamin supplement works for bad hair/nails/skin depends on whether or not the person taking it has vitamin deficiencies. Vitamin deficiencies can come from poor diet choices, starvation, long-term use of some medications (eg: B12 deficiency with omeprazole or metformin), or malabsorption problems (= inability to absorb certain nutrients, eg: Celiac disease).
