At Norwood 1, the best treatment is usually prevention, not surgery. Your hairline is intact, which means you have every advantage when it comes to keeping it that way. This article covers your options from the evidence-based to the experimental, ranked by clinical support.

Why Treatment at Norwood 1 Is Different
Most hair loss content assumes you already have visible loss. At Norwood 1, you do not. This puts you in a uniquely strong position: you are not trying to recover lost ground, you are trying to maintain what you have.
This distinction matters clinically. Treatments that are designed to regrow hair in areas of thinning work even better at preventing loss in follicles that are still fully active. The earlier you start, the broader your options and the stronger your outcomes.
According to population data, 68% of men first notice hair loss at Norwood 2 or 3, meaning the majority of men have already lost ground before they begin treatment. Starting at Stage 1 puts you ahead of that curve.
Treatment Option 1: Finasteride
Finasteride is the gold standard first-line treatment for male pattern baldness (androgenetic alopecia). It works by inhibiting the type II 5-alpha reductase enzyme, which converts testosterone into dihydrotestosterone (DHT). DHT is the primary driver of follicular miniaturization in genetically susceptible men.
Clinical evidence: A landmark five-year placebo-controlled study found that 99% of men taking finasteride maintained or improved their hair compared to 83% of those on placebo who continued to lose hair. At the one-milligram daily dose, DHT levels in the scalp drop by approximately 60%.
How to use it: One milligram orally per day. Results take three to six months to appear and peak around twelve months. You must continue taking it to maintain results.
Side effects: A subset of men (approximately 2 to 4% in clinical trials) report sexual side effects including reduced libido or erectile changes. These resolve in the majority of cases after stopping. Post-finasteride syndrome is a contested but documented phenomenon worth discussing with your prescribing physician.
Topical finasteride: A topical formulation (0.25% to 1% applied to the scalp) is an alternative for men concerned about systemic side effects. Early research suggests it reduces scalp DHT effectively with lower serum levels, though long-term data is still accumulating.
Treatment Option 2: Minoxidil
Minoxidil is the other FDA-approved treatment for male pattern hair loss. It operates through a different mechanism to finasteride: it is a vasodilator that extends the anagen (active growth) phase of the hair cycle and may also open potassium channels in follicle cells.
Clinical evidence: Topical 5% minoxidil outperforms the 2% concentration in clinical trials. At 48 weeks, men using 5% minoxidil showed 45% more regrowth than those using 2%. In men with early-stage loss (which includes Norwood 1 to 3), response rates are highest.
How to use it: One milliliter of topical solution or half a capful of foam applied to the scalp twice daily. Allow it to dry before sleeping. Oral minoxidil at low doses (0.625mg to 2.5mg daily) is increasingly prescribed as an off-label alternative with strong anecdotal and emerging clinical support.
Side effects: Topical minoxidil can cause scalp irritation, initial shedding (telogen effluvium) for the first six to eight weeks, and unwanted facial hair growth in some users. Oral minoxidil carries cardiovascular considerations and should only be used under physician supervision.
Treatment Option 3: Combination Therapy
Using finasteride and minoxidil together is more effective than either alone. A study published in the Journal of the American Academy of Dermatology demonstrated that men on combination therapy achieved significantly greater hair count improvements at 48 weeks compared to either monotherapy group.
At Norwood 1, this combination is a powerful preventive strategy. You are fortifying follicles that are still at full health, making it much harder for DHT-driven miniaturization to take hold.
Many clinicians recommend starting with one medication, assessing tolerance over three months, and then adding the second if the first is well tolerated.
Treatment Option 4: Low-Level Laser Therapy (LLLT)
LLLT devices (laser caps, laser combs, and helmets) use red light at specific wavelengths (typically 650 to 670nm) to stimulate hair follicles. The FDA has cleared several devices for hair loss under the 510(k) pathway, meaning they are considered safe though not held to the same efficacy standard as drugs.
Clinical evidence: A 2014 randomized controlled trial found that men using an LLLT helmet device saw a 39% increase in hair growth rate compared to sham devices over 16 weeks. Effects are generally modest compared to finasteride or minoxidil.
How to use it: Most devices require 20 to 30 minutes of use, three times per week. They can be used alongside medications. Prices range from around $200 to $900 for consumer-grade devices.
At Norwood 1, LLLT is best considered an adjunct rather than a standalone treatment.
Treatment Option 5: Ketoconazole Shampoo
Ketoconazole is an antifungal agent found in shampoos like Nizoral. At 1% to 2% concentration, it shows mild anti-androgenic properties in the scalp, potentially reducing DHT-driven inflammation around hair follicles.
A small clinical trial found that 2% ketoconazole shampoo produced results comparable to 2% minoxidil in terms of hair density scores, though larger studies are needed. It is commonly recommended as a supportive measure alongside primary treatments.
How to use it: Two to three times per week, leave on the scalp for two to five minutes before rinsing.
Treatment Option 6: Platelet-Rich Plasma (PRP)
PRP therapy involves drawing a small amount of your blood, centrifuging it to concentrate the platelet-rich portion, and injecting it into the scalp. Platelets contain growth factors that may stimulate follicle activity.
Clinical evidence: Evidence is mixed but generally positive for early-stage loss. A 2017 meta-analysis found PRP significantly increased hair count, density, and thickness compared to controls. However, protocols vary widely between clinics, making results difficult to standardize.
How to use it: Typically three sessions, four to six weeks apart, followed by maintenance sessions every six to twelve months. Costs range from $500 to $2,000 per session.
At Norwood 1, PRP is most appropriate for men showing subclinical miniaturization on trichoscopy, even with an intact visible hairline.

What to Avoid at Norwood 1
Not all marketed products have clinical support. Biotin supplements, caffeine shampoos, and many "hair growth" serums sold online lack randomized controlled trial evidence for androgenetic alopecia. Spending on unproven products delays starting treatments that actually work.
Hair transplant surgery is also not indicated at Norwood 1 for loss-related reasons. Any surgeon recommending extensive grafting at this stage without clear medical justification warrants a second opinion.
Frequently Asked Questions
What does Norwood 1 look like?
Norwood 1 is the baseline on the Norwood scale, characterized by a full, intact hairline with no visible recession at the temples or crown. Most men at this stage have the same hairline they had in their late teens. There is no thinning, no bald patches, and no significant miniaturization visible to the naked eye.
How many grafts do I need at Norwood 1?
At Norwood 1, most men do not require any grafts. The hairline is intact and hair density is typically within normal range. If a very minor cosmetic refinement is requested, a surgeon might place 200 to 500 grafts, but this is uncommon and is not medically indicated for hair loss treatment.
What are the best treatments at Norwood 1?
The best approach at Norwood 1 is monitoring and early prevention. Clinically proven treatments include finasteride and minoxidil, used separately or together. These medications can slow or halt progression before significant loss occurs. A dermatologist or hair loss specialist can assess your individual risk based on family history and scalp health markers.
