Studies show that too much vitamin A can also contribute to hair loss Sweet potatoes, carrots, pumpkins, spinach, and kale are all high in beta-carotene, which is turned into vitamin A. Vitamin A can also be found in animal products such as milk, eggs, and yogurt.
Vitamin D
A 2019 review found evidence to suggest a link between vitamin D deficiency and alopecia areata, which can involve severe hair loss. According to the review, some research also suggests that symptoms of alopecia areata may be more severe in people with low levels of vitamin D. However, the authors of a 2016 study that collected information from 55,929 women in the United States did not find a strong link between total vitamin D intake and hair loss in alopecia areata. There is also little evidence to suggest that vitamin D can lead to hair regrowth.
Some studies have found that low vitamin D levels may be associated with female pattern hair loss, which is the most common type of hair loss in women. However, further studies are necessary to confirm this potential link. However, many experts agree that this daily recommendation is likely too low to reach optimal blood levels, which most experts agree lies between 30 and 60 nanograms per milliliter (ng/ml) .

However, taking vitamin D in very high doses can lead to toxicity that may result in severe complications.
Taking vitamin D with a meal that contains fat will improve the absorption of this vitamin.
