Hair Growth Supplements: Honest Answer
The short answer: It depends on your situation.
Supplements That Have Some Evidence
- Nutrafol - Most researched OTC option; studies show modest improvement, especially for stress/hormone-related thinning
- Viviscal - Has clinical trials supporting it; works better for nutritional deficiency-related loss
- Biotin supplements (like Sports Research Biotin) - Only genuinely helps if you're actually biotin-deficient, which most people aren't
When Supplements Are Probably Enough
- Mild, diffuse thinning
- Hair loss from nutritional deficiencies, stress, or postpartum changes
- You want general hair health improvement
When You Likely Need Prescription Treatment
- Androgenic alopecia (pattern baldness) - supplements won't stop this
- Significant or rapid loss
- Receding hairline or bald patches
Proven Prescription/Clinical Options
- Minoxidil (Rogaine or generic) - OTC but clinically proven
- Finasteride/Dutasteride - prescription, very effective for men
- Hims, Keeps, or Nutrafol Women's telehealth platforms make getting prescriptions easier
My Recommendation
See a dermatologist first to identify the cause - that determines the right treatment. Supplements alone rarely reverse significant hair loss.
