We’ve periodically reported on topics related to hair growth treatments including the use of low dose oral minoxidil, alopecia, and platelet rich plasma, PRP. Many patients ask about the purported benefits of nutritional supplements for hair loss. An extensive review of multiple studies published in JAMA Dermatology in November 2022 concluded that a wide range of products have potential but definitive evidence of safety and effectiveness were lacking due to factors such as the small size of the study groups, the mix of various types of hair loss, and the lack of control groups.
Supplements could have a positive role in hair growth, and might be considered in selected situations, but better studies are needed. While certain deficiencies such as vitamin D and zinc may cause hair loss there are many other factors to consider. When experiencing hair loss, it’s best to consult your dermatologist for evaluation which typically includes taking a thorough history and selected blood tests. A scalp biopsy might be performed when indicated.
