    TLDR Eating the right nutrients can improve hair health, but taking extra supplements usually doesn't help unless you have a deficiency.
    In the 2013 document, Dr. Andreas M. Finner highlighted the role of nutrition in hair health, noting that deficiencies in various nutrients can lead to hair loss and other hair-related issues. Specific deficiencies such as those in protein, vitamins, and minerals were discussed, along with their symptoms. The document pointed out that while nutritional deficiencies can cause hair disorders, they are rare in developed countries and often overestimated. The effectiveness of dietary supplements for hair growth is generally not well-supported by evidence, except in cases of specific deficiencies. The document also discussed the potential negative effects of nutrient excess and toxins on hair health. A study involving 30 women indicated that a supplement containing L-cysteine, medicinal yeast, and pantothenic acid could benefit those with diffuse telogen effluvium. The conclusion emphasized that while treating specific nutrient deficiencies can improve hair health within 3 to 6 months, unspecific supplementation is not recommended without confirmed deficiencies, except for telogen effluvium treatment with L-cysteine. Further research is needed to confirm the benefits of nutritional supplements on hair.
