Additionally, as we noted some nutrient deficiencies can contribute to hair shedding, according to a scientific review in Dermatology Practical & Concept. This could be anything from the obvious protein macro to the more granular micronutrients like biotin, zinc, etc.
Thus, if your hair loss woes are rooted in nutritional gaps, taking hair supplements can help, says Dina Strachan, M.D., board-certified dermatologist and director of Aglow Dermatology.* But take note: According to Strachan, if you don’t have an actual nutrient inadequacy relevant to hair health, these supplements may not make a difference (in terms of hair growth, at least). That said, if you suspect you’re low in a certain nutrient, chat with your practitioner before investing in hair supplements.
