At Norwood 2, non-surgical treatment is highly effective because follicles are still viable and the DHT-driven miniaturization process is early. Finasteride achieves an 80-90% success rate in halting progression. Minoxidil produces density improvement in 40-60% of users. PRP adds a further 30-40% density increase when used alongside these medications. Together, these options can maintain your current stage indefinitely for a significant proportion of patients.
1. Finasteride (Oral)
Finasteride is the most evidence-backed non-surgical option available for androgenetic alopecia. It inhibits the conversion of testosterone to DHT by blocking 5-alpha reductase type II, reducing scalp DHT by 60-70%.
Clinical performance:
- Halts progression in 86% of users at 2 years
- Produces visible regrowth in approximately 65% of users
- Most effective when started early (Norwood 2 is an optimal starting stage)
- Effects are maintained with continued use; stopping finasteride reverses gains within 12 months
Dosing: 1mg/day orally. Generic finasteride is widely available at $15-$30/month. The brand-name equivalent (Propecia) is significantly more expensive with no clinical advantage.
Time to visible effect: Reduced shedding within 3-6 months. Visible density improvement by 9-18 months. Full assessment at 24 months.
Side effect profile: Sexual side effects (reduced libido, erectile dysfunction) in 2-4% of clinical trial participants. These typically resolve on discontinuation. Patients with concerns should discuss the risk-benefit profile with a prescribing physician before starting.
2. Minoxidil (Topical or Oral)
Minoxidil extends the anagen growth phase and increases blood flow to the follicle through potassium channel opening. It does not address DHT and does not stop progression, but it directly stimulates follicular activity.
Clinical performance:
- 40-60% of men see measurable density improvement with consistent use
- Topical 5% outperforms 2% with comparable tolerability
- Oral minoxidil (0.625-2.5mg/day) reaches all scalp zones more consistently than topical application
- Most effective in areas where follicles are miniaturized but not fully dormant
Topical application: Applied directly to the temple and hairline zones morning and evening. Allow 2-4 hours before rinsing for maximum absorption.
Oral minoxidil: Increasingly prescribed off-label for androgenetic alopecia. Lower doses (0.625-1.25mg/day) are typically used in men, with fewer systemic effects than higher doses.
Side effects: Topical: initial shed (telogen effluvium, resolves in 6-8 weeks), scalp irritation, occasional facial hair growth. Oral: hypertrichosis (increased body hair), fluid retention, potential for low blood pressure.
3. Combination Therapy: Finasteride + Minoxidil
Using finasteride and minoxidil together addresses two distinct pathways: DHT suppression and follicular stimulation. The additive effect is well-supported in clinical literature.
A 2021 study in Dermatologic Therapy found combination users at Norwood 2-3 showed significantly better hair retention at 24 months than either monotherapy group. The practical implication: if you start treatment at Norwood 2, the combination approach is the most effective way to both halt progression and improve density.
Monthly cost: approximately $30-$55 for both medications in generic form.
4. Topical Finasteride
Topical finasteride (applied to the scalp at 0.1-0.25% concentration) achieves local DHT suppression with lower systemic absorption than oral finasteride. Scalp DHT suppression is comparable to oral dosing in some studies, with significantly lower serum DHT reduction.
This is the preferred option for men who are concerned about systemic side effects from oral finasteride. It is not available as a mass-market product in most countries; compounding pharmacies produce it to prescription. Availability varies by country.
5. Platelet-Rich Plasma (PRP)
PRP therapy extracts growth factors from a patient's own blood (PDGF, VEGF, IGF-1, and others) and injects the concentrated plasma into the scalp. The growth factors stimulate follicular activity and may prolong the anagen phase.
Clinical performance:
- A 2023 meta-analysis found PRP increased hair density by 30-40% in androgenetic alopecia patients
- Results are highly variable across clinics, depending on preparation protocol and platelet concentration
- PRP does not address DHT and does not halt progression on its own
- Best used as an adjunct to finasteride, not a replacement
Practical considerations: PRP requires clinic visits every 4-6 weeks for an initial series (typically 3 sessions), then maintenance every 6-12 months. Cost per session ranges from $400-$1,500.
At Norwood 2, PRP is most valuable for patients who cannot or will not take finasteride and want a non-pharmaceutical approach that has meaningful supporting evidence.
6. Low-Level Laser Therapy (LLLT)
LLLT devices use red light at 650-670nm wavelengths to stimulate cellular metabolism in hair follicles. FDA-cleared devices are available as helmets, caps, and handheld combs.
Clinical performance:
- Produces statistically significant increases in hair density in controlled trials
- Effect size is smaller than finasteride or minoxidil
- Works best as an adjunct to medications rather than a standalone treatment
- Requires consistent use: 20-30 minutes, 3x per week
Cost: Entry-level combs ($200-$400). Mid-range caps ($500-$1,200). High-end helmets ($1,500-$3,000). One-time purchase with no ongoing cost.
LLLT is most useful for patients who want an additional supportive treatment without adding another medication.
7. Dutasteride (Off-Label)
Dutasteride inhibits both type I and type II 5-alpha reductase, suppressing DHT more completely than finasteride. Studies comparing dutasteride 0.5mg to finasteride 1mg consistently show greater hair count improvements with dutasteride.
It is FDA-approved for BPH but not for hair loss in most countries. South Korea has licensed it specifically for androgenetic alopecia. It is prescribed off-label in most other markets.
Side effect profile: Higher than finasteride due to greater DHT suppression and longer half-life. Men with higher progression rates who did not respond adequately to finasteride are the typical candidates for switching.
8. Ketoconazole Shampoo
Ketoconazole 2% (prescription-strength) has mild anti-androgenic properties and may reduce scalp DHT activity locally. Used 2-3x per week as a scalp shampoo, it is an inexpensive adjunct with a negligible side effect profile.
It does not produce meaningful hair regrowth on its own but is commonly recommended as part of a comprehensive non-surgical protocol alongside finasteride and minoxidil.

Starting a Non-Surgical Protocol at Norwood 2
The optimal starting protocol for most Norwood 2 patients:
- Get a prescription for finasteride from a dermatologist or hair specialist. Start at 1mg/day.
- Add topical or oral minoxidil within the first month if comfortable with both.
- Reassess at 12 months with standardized photography and ideally trichoscopy.
- Consider PRP as an adjunct if budget allows and clinical access is available.
- Evaluate surgery candidacy after 12+ months of stable hair loss on medication, if desired.
The goal at Norwood 2 is to remain at this stage as long as possible while keeping all surgical options open for the future.

FAQ
What is the most effective non-surgical treatment for Norwood 2?
Finasteride is the most effective non-surgical option, halting progression in 86% of users and producing regrowth in around 65%. Combined with minoxidil, the outcomes improve further. For Norwood 2, early treatment with this combination preserves the most hair over time.
Does minoxidil work at Norwood 2?
Yes, for many patients. Studies show 40-60% of men see measurable density improvement with consistent minoxidil use. It works best on follicles that are miniaturized but still functional. Minoxidil does not stop progression on its own; it is most effective combined with finasteride.
Can PRP regrow hair at Norwood 2?
PRP can increase hair density by 30-40% in suitable candidates, but it does not address the underlying DHT mechanism driving progression. PRP is best used as a complementary treatment alongside finasteride rather than as a standalone option. Results require maintenance sessions every 6-12 months.
