  1. Multivitamin
  2. Vitamin D
  3. Biotin
  4. Saw palmetto
  5. Ginseng


Scientists have determined that vitamins A, B, C, D, iron, selenium, and zinc are all important to the hair growth and retention processes, specifically with cell turnover. Ask your doctor to prescribe you the most suitable multivitamin supplement.

Vitamin D

One 2018 study noted that vitamin D is associated with nonscarring alopecia. Treating deficiencies may help with regrowth. Speak with your doctor about taking 800 to 1000 IU daily.


Biotin — vitamin H or B7— is involved in fatty acid synthesis in the body. This process is essential to the hair life cycle and you may experience hair loss if you have a deficiency. Speak with your doctor about taking three to five milligrams daily.

Saw palmetto

Derived from the fruit of American dwarf pine trees, this herb may help men maintain levels of testosterone. One 2004 journal article revealed that some 60 percent of participants taking saw palmetto experienced improved hair growth. The dosage in the study was 200 milligrams daily.


Ginseng contains certain phytochemicals that may promote hair growth on the scalp. Further study is needed to recommend specific dosages. In the meantime, speak with your doctor about taking ginseng supplements or consider trying topical solutions that contain this ingredient.
