Hair Loss Treatments Compared: Finasteride, Minoxidil, and Beyond

Hair loss has more snake oil per square foot than almost any other consumer health category. Most products in the space have no clinical evidence. A few do. Knowing which is which makes choosing a treatment — or a telehealth program — much simpler.

This guide covers the treatments that actually have peer-reviewed evidence, the ones that don't, and how to pick a program that focuses on the real ones.

The two treatments with the strongest evidence

Finasteride (oral, prescription)

Finasteride is the most well-studied medication for male pattern hair loss. It works by reducing dihydrotestosterone (DHT), the androgen primarily responsible for follicle miniaturization in androgenetic alopecia.

What the evidence shows

• Long-term studies show finasteride halts further hair loss in roughly 80–90% of men and produces visible regrowth in many.
• Effects appear in 3–6 months. Plateau around 12 months.
• Stopping finasteride causes loss of any gains within 6–12 months. It's a maintenance medication.

Side effects

• Common: small percentage report decreased libido or sexual side effects. Most resolve on stopping.
• Rare: persistent post-finasteride syndrome — debated in the literature, but worth taking seriously if you're concerned.

A clinician should review your history before prescribing.

Minoxidil (topical or low-dose oral)

Minoxidil works through a different mechanism — it improves blood flow to follicles and shortens the resting phase of the hair cycle.

What the evidence shows

• Effective for both male and female pattern hair loss.
• Topical (5% solution or foam) has decades of data.
• Low-dose oral minoxidil has gained traction in recent years. A growing body of evidence supports it as effective and reasonably safe under clinical supervision.

Side effects

• Topical: scalp irritation, occasional shedding in early weeks (paradoxically, often a sign it's working).
• Oral: systemic effects possible (heart rate changes, fluid retention) — needs clinician monitoring.

The combination

Used together, finasteride and minoxidil produce better results than either alone. Most legitimate hair loss telehealth programs build their plans around this combination.

Treatments with moderate evidence

Dutasteride

Stronger than finasteride at reducing DHT (it blocks both 5α-reductase enzymes). More effective in some studies, but with a slightly higher side-effect profile. Off-label for hair loss in the U.S.

Microneedling

Creating tiny channels in the scalp to stimulate follicles. Limited but real evidence of effectiveness, especially when paired with topical minoxidil.

Low-level laser therapy (LLLT)

Devices like laser caps or combs. Some evidence of benefit, but results are modest and devices are expensive.

Treatments with weak or no evidence

Most "hair growth" supplements

Biotin, collagen, multivitamins — unless you're actually deficient (most people aren't), there's no strong evidence these regrow hair. Biotin supplements specifically can interfere with lab tests, including thyroid panels.

Notable exception: Nutrafol has actual clinical trials behind it, with modest but real effects. It's a nutraceutical, not a supplement in the loose sense.

"DHT-blocking" shampoos

Most are saw palmetto-based and have no peer-reviewed evidence of regrowing hair. They don't hurt, but they're not the medicine.

Essential oils, scalp massage, peppermint oil

Pleasant. Largely placebo for hair loss.

How to choose a hair loss telehealth program

The signal-to-noise question for any hair loss platform is: does the program actually offer finasteride and minoxidil — and is a real clinician reviewing you?

Three options worth considering:

• Keeps — focused exclusively on hair loss. Cheapest option. Generic finasteride and minoxidil. Bare-bones but effective.
• Hims — broader brand, multi-program account, smoother UX, slightly higher pricing. Same active ingredients.
• Nutrafol — supplement-only, OTC, no prescription needed. Reasonable adjunct, not a replacement.

For the prescription side (Keeps or Hims), you'll fill out an intake, upload a photo or two, and a clinician will decide whether the medication is appropriate. Some men aren't candidates for finasteride — your clinician will tell you why if so.

Realistic timeline

If you start a program today:

• Month 1–2: No visible change. Possibly mild shedding (a normal adjustment).
• Month 3–4: Stabilization — loss slows.
• Month 6: Early regrowth visible to you.
• Month 9–12: Regrowth visible to others.
• Beyond: Maintenance.

Hair loss treatment is the long game. Patience matters more than the brand.

Bottom line

Pick a program that prescribes finasteride and minoxidil through a real clinician review, start it, take it daily for a year, and don't get distracted by every supplement on Instagram. The medications work — but only if you actually take them.
