The hair loss industry thrives on desperation. When you're losing your hair, you're vulnerable to products that promise more than they can deliver. Here's our honest assessment of the products and approaches that don't work — and why they keep getting sold.

Biotin Supplements

Our strongest opinion on this list: biotin supplements are the biggest scam in hair loss marketing. Biotin deficiency can cause hair shedding — but biotin deficiency is extremely rare in people eating a normal diet. If your biotin levels are normal (and they almost certainly are), supplementing does absolutely nothing for androgenetic alopecia. It doesn't address DHT. It doesn't stimulate follicles. It's a B vitamin.

Yet biotin is the #1 ingredient in products marketed for "hair growth." Why? Because it's cheap to include, easy to market, and sounds scientific. The clinical evidence for biotin in pattern baldness is zero.

Hair Growth Shampoos

Shampoo sits on your scalp for 30–60 seconds before being rinsed off. No active ingredient — no matter how effective — is meaningfully absorbed in that timeframe. Hair growth shampoos are cosmetic products that clean your hair. That's it.

One exception: Ketoconazole shampoo (Nizoral) has mild anti-androgenic properties and some evidence as an adjunct to real DHT-blocking treatment when used 2–3x per week. But it's an adjunct, not a standalone treatment.

Laser Caps and Combs

These are FDA-cleared — but "cleared" means "probably safe," not "proven effective." The evidence is limited, inconsistent, and mostly from small, manufacturer-funded studies. At $300–$800+, the cost-benefit ratio is terrible compared to proven treatments that cost a fraction.

Essential Oils and Scalp Massages

Rosemary oil gets mentioned in every natural hair loss article on the internet. There's one small study comparing it to minoxidil. The methodology is weak. The results are not reproducible at scale. Our opinion: this is wishful thinking dressed up as science.

Scalp massages feel nice. They don't address DHT. They don't reverse miniaturization.

Anything That Claims to Be a "Cure"

There is no cure for androgenetic alopecia. Any product that uses the word "cure" is either breaking FDA regulations or not talking about male pattern baldness. If something sounds too good to be true, it is.

How to Spot Junk Products

  • They lead with testimonials instead of clinical data
  • They claim to "cure" or "reverse" baldness completely
  • Their ingredient list is mostly vitamins and minerals
  • They don't explain the mechanism — just show before/after photos
  • They have no IRB-approved or peer-reviewed clinical studies
  • They cost more than proven treatments that have decades of data

What to Spend Your Money On Instead

A quality DHT blocker (natural like Procerin or prescription), minoxidil, and consistency. That combination — at $50–80/month total — will outperform any amount spent on biotin, shampoos, laser caps, or essential oils.
