Honest Answer: It Depends on the Cause
Hair growth supplements can work, but only in specific situations. Here's a straightforward breakdown:
Supplements Worth Trying First
For nutritional deficiencies:
- Nutrafol - Well-researched, addresses stress hormones and inflammation; one of the most clinically studied OTC options
- Viviscal - Has decent clinical trials behind it, particularly for women with thinning hair
- Sports Research Biotin - Only helpful if you're actually biotin-deficient (most people aren't)
Realistic expectation: Results take 3-6 months and work best for stress-related or nutritional shedding
When You Likely Need Prescription Treatment
- Pattern baldness (receding hairline, crown thinning) - supplements won't stop this
- Significant or rapid hair loss
- You've tried supplements for 6 months with no results
Prescription options to ask a doctor about:
- Finasteride/Dutasteride (men, women)
- Minoxidil oral - stronger than topical
- Hims or Keeps - convenient telehealth platforms for prescription hair loss treatment
Bottom Line
Get a simple blood test first to check iron, vitamin D, and thyroid levels. That tells you whether supplements make sense or whether you need a dermatologist.
