However, further studies are necessary to confirm this potential link.
More research is also necessary to confirm the potential benefits of vitamin D for hair growth. People can find out their vitamin D levels and whether or not they are deficient by asking their doctor for a blood test. An excessively high dose would be over 50,000 IU or when blood levels of vitamin D are greater than 150 ng/ml .
