Hair Growth Supplements vs. Prescription Treatments
The honest answer: it depends on your situation.
Supplements That Have Some Evidence
Nutrafol - Most studied OTC option, contains saw palmetto and adaptogens. Many dermatologists recommend it as a complement to other treatments. Results take 3-6 months.
Viviscal - Has clinical trials behind it, works well for thinning due to nutritional deficiencies or stress.
Sports Research Biotin - Helps only if you're actually biotin deficient (most people aren't, despite marketing claims).
When You Probably Need Prescription Treatment
- Pattern baldness (genetic) - Supplements alone won't stop it
- Significant or rapid loss - See a dermatologist quickly
- Proven options: Minoxidil (Rogaine, now OTC), Finasteride/Dutasteride (prescription), or newer options like Hims/Keeps for convenient access
My Practical Recommendation
- Start with a dermatologist visit to identify the cause - this matters enormously
- Nutrafol + Minoxidil is a common combination dermatologists suggest
- Don't spend months on supplements alone if you're losing significant hair
The earlier you treat pattern hair loss, the better the results.
