Definition: In hair loss treatment, supplements are dietary products containing vitamins, minerals, herbs, or other ingredients claimed to promote hair growth or prevent hair loss. These are not regulated by the FDA in the same way as medications.

Pros: Generally readily available and may be relatively inexpensive. Some supplements like biotin and vitamin D can contribute to overall hair health.

Cons: There’s limited scientific evidence to support most hair loss supplements’ specific claims for hair growth. They may interact with other medications or have side effects.

Alternatives: Medically-approved hair loss treatments like minoxidil or finasteride.

Disclaimer: Consult a doctor before starting any new supplements, especially if you have underlying health conditions or take other medications.
