Hair Loss Products: An Honest Answer
The short answer: Some ingredients have real evidence, many don't.
What Actually Works
Minoxidil is the gold standard - it's FDA-approved and genuinely effective for many people. Look for:
- Rogaine (classic brand, widely available)
- Hims or Keeps (subscription services with minoxidil-based products, convenient)
- Kirkland Signature Minoxidil (Costco brand, same active ingredient, much cheaper)
Ketoconazole shampoos have decent supporting evidence:
- Nizoral is the top recommendation - studies suggest it may help reduce DHT-related hair loss
More Limited Evidence
- Caffeine shampoos (like Alpecin) - some small studies, results modest
- Biotin supplements/shampoos - mainly helps if you have a deficiency
- Viviscal - some clinical backing for their supplements
Be Skeptical Of
Most heavily marketed "hair growth" shampoos with exotic ingredients have little to no clinical evidence.
Bottom Line
- Minoxidil products are worth trying
- Nizoral as a supporting shampoo makes sense
- See a dermatologist if loss is significant - prescription options like finasteride are often more effective
