Hair Growth Supplements vs. Prescription Treatments
Honest answer: It depends on the cause of your hair loss.
Supplements That Have Some Evidence
Nutrafol - Most clinically studied OTC supplement; contains saw palmetto, ashwagandha, and marine collagen. Reasonable evidence for stress-related or hormonal thinning.
Viviscal - Has multiple clinical trials showing modest improvement, especially for women with thinning hair.
Sports Research Biotin - Helps only if you have a biotin deficiency (most people don't).
Honest limitation: Supplements generally produce modest results and work best for nutritional deficiencies or mild thinning.
When You Probably Need Prescription Treatment
- Genetic hair loss (androgenetic alopecia) - Supplements rarely stop this effectively
- Significant or rapid shedding
- Visible bald patches
Proven prescription options:
- Minoxidil (also OTC as Rogaine) - works for many people
- Finasteride/Dutasteride - very effective for men
- Hims/Hers or Keeps - telehealth services that make prescriptions convenient and affordable
My Recommendation
Start with a dermatologist or trichologist to identify the cause first - that determines everything. Spending money on supplements without knowing why you're losing hair is often wasted.
