Hi, I’m Dr Harth!

I’ve been a dermatologist for over 30 years, and if there’s one thing I’ve learned, it’s that the little things we do every day—what we put on our skin, what we eat, how we take care of ourselves—can make a big difference. I love breaking down the science of skincare and haircare and making it easy for people to find what actually works.

The Best Hair Growth Products for Men in 2025

Last updated: 05/20/2025

I set out on a mission to find the ultimate Hair Regrowth treatment—one that truly delivers on results, quality, and efficacy. With so many options on the market, it can be overwhelming to know which one is actually worth the investment.

Let’s be honest—brands aren’t always the most transparent, and marketing claims can be misleading. That’s why I took a methodical, hands-on approach to testing, ensuring that I could provide an honest, science-backed review.

Below, you’ll find a detailed breakdown of my findings, including how each hair growth product performs, key factors that influenced my ratings, and the subtle differences that make a big impact.

First things first, why choose the right hair regrowth solution?

Before we dive into the product reviews, let’s talk about why selecting the right hair regrowth treatment is so important. Many people assume their hair loss is simply genetic or due to age, but other factors—like using the wrong treatment or lacking key ingredients—can play a major role.Here’s why finding the right product matters:

  • Uses clinically proven ingredients – Not all hair regrowth treatments are backed by science. The right formula contains ingredients with proven effectiveness in stimulating hair growth and reducing shedding.

  • Targets the root cause – Whether it’s hormonal imbalance, nutrient deficiencies, or scalp inflammation, an effective product addresses the underlying issue, not just the symptoms.

  • Minimizes side effects – Harsh chemicals can cause irritation, dryness, or even worsen hair loss. A well-formulated treatment supports hair health without unwanted side effects.

  • Boosts confidence – Thicker, healthier hair can transform your appearance and improve your overall well-being.

Switching to the right hair growth solution can make a noticeable difference in just a few months. Now, let’s get into the top products of 2025 and see which one delivers the best results.

How I Scientifically Analyzed Each Hair Growth Product

I researched and evaluated four leading hair regrowth solutions: MDhair, Hims, Nutrafol, Rogaine, Keeps, BosleyMD, Nioxin, and Spartan. To ensure fair results, I followed a structured testing process:

  • Ingredient Effectiveness: Analyzed each formula, considering scientific research and dermatologist approval.

  • User Insights: Collected real customer feedback from Trustpilot, Reddit, and other online platforms.

  • Clinical Trial Data: Reviewed clinical studies from relevant brands to assess scientific credibility.

  • Comparative Results: Scored each product based on effectiveness, formulation quality, dermatologist approval, and overall value.

My verdict

MDhair is revolutionizing hair regrowth with a clinically proven and dermatologist-designed approach. Unlike generic, one-size-fits-all treatments, MDhair’s formulas are customized to each individual’s needs, ensuring a targeted and effective solution.

Hims Hair Regrowth Treatment

Try Now

What I Love

Widely available: Easy to purchase online and in major retail stores.
Option for generic oral drug: An FDA-approved oral drug used to treat male pattern hair loss.
Choice of non-medicated and medicated options: I appreciate the flexibility to choose an option that suits you best.

What could be better

Limited personalization: Not much personalization or ingredient variety compared to MDhair.
Very long health quiz: Medicated options require filling out a very long quiz and there’s no automatic image analysis of the scalp.
Off-label medications: Provides off-label medications that is not FDA-cleared.
Not focused solely on hair loss: Hims and Hers offer many products, and hair regrowth doesn’t seem to be a core focus.

My overall rating

Hims & Hers offers a budget-friendly and widely accessible range of hair care products, including topical treatments and non-medicated options.

However, the process can be detailed, requiring a comprehensive questionnaire to tailor product recommendations. It also lacks the personalization and advanced scalp care benefits of MDhair, focusing primarily on a select range of treatments without many added nutrients for scalp health. Since hair regrowth isn’t the brand’s main focus, those seeking a more advanced, customized solution may find better alternatives.

Third Place
Nutrafol Men's Hair Growth Supplements

Try Now

What I Love

Clinically tested: Backed by peer-reviewed clinical studies showing visible improvements in hair growth, thickness, and scalp coverage after 3–6 months of use.
Natural ingredients: Includes saw palmetto (a natural DHT blocker), ashwagandha (for stress reduction), marine collagen, curcumin, and tocotrienols—scientifically selected to support scalp health and hair follicle function.
Hormone-free and drug-free: Another option for men looking to avoid pharmaceutical treatments and their potential side effects.
Visible results in clinical trials: In a clinical trial, 79% of men taking Nutrafol were rated by blinded investigators as improved in hair growth compared to 51% in the placebo group.

What could be better

Limited customization: Offers fewer ingredient options and personalization compared to other companies. It does not offer medicated OTC products like minoxidil.
Based on the quiz: Lacks the significant benefits of personalized free scalp image analysis offered by MDhair.
Focus on oral supplements: Very limited choice of topical hair growth products.
Limited amount of collagen in each capsule: Original Nutrafol capsules contain a small amount of collagen compared to MDhair's marine hydrolyzed peptides supplements.
Four capsules a day: Due to the relatively small amount of collagen and other ingredients, it requires taking four capsules a day, which can be too much for many customers.
Expensive for a supplement: Costs $79 per month for a single product, making it a pricey option.

My overall rating

Nutrafol Men is a clinically validated supplement for male hair thinning. With its DHT blockers like saw palmetto and stress adaptogens like ashwagandha, it addresses the root causes of androgenetic alopecia without the risks associated with off label drugs. That said, Nutrafol comes with some drawbacks: it offers limited customization, lacks topical product options, and doesn't include free scalp image analysis like more tech-enabled platforms such as MDhair. Additionally, each daily dose requires taking four capsules, and the $79/month price point can be a barrier for budget-conscious users. The collagen content per capsule is also relatively low compared to marine-based peptide supplements.

Nutrafol Men is a well formulated clinically validated natural supplement for male hair thinning, offering drug-free ingredients that target hormonal and stress-related causes. However, it lacks customization, topical options, and advanced digital support like scalp image analysis. Its high price and four-capsule daily dose may also limit appeal for some users.

Fourth Place
Rogaine

Try Now

What I Love

FDA-approved Minoxidil: Promotes hair regrowth but not suitable for all types of hair loss.
Budget-friendly: More affordable than customized or multi-ingredient solutions.

What could be better

One-size-fits-all formula: Not tailored to different hair loss causes. No quiz or image analyses of the scalp.
May cause scalp irritation: Some users experience flaking and redness. Does not offer specialized expert support or fine-tuning options.
May need to use indefinitely: Stopping treatment can lead to hair loss resuming.
Limited ingredients: Offers fewer ingredient options and personalization compared to MDhair.

My overall rating

Rogaine is a budget-friendly, widely used hair regrowth treatment featuring FDA-approved Minoxidil. It’s easy to find, available in foam or liquid, and works well for many users.

However, it’s a one-size-fits-all formula, lacking customization for different hair loss causes. Some users experience scalp irritation, and long-term use is often required to maintain results. With fewer additional ingredients than other options, those seeking a more tailored approach may prefer a multi-ingredient, personalized solution.

Fifth Place
Keeps

Keeps Kit
Try Now

What I Love

Clinically proven ingredients: Uses FDA-approved Minoxidil to support hair regrowth and prevent further loss. Trusted by dermatologists.
Subscription model: Offers treatment plans with convenient home delivery and refill reminders.
Free consultation with licensed doctors: Includes a virtual doctor's visit to evaluate your hair loss and determine the right treatment approach.

What could be better

Limited focus on scalp health: Not focused solely on hair loss: Keeps claims to help treatment multiple unrelated disorders products, including erectile dysfunction and weight loss.
Concern about off-label treatments: A recent FDA warning letter raised concerns about the safety of off-label treatments, including sexual dysfunction side effects.
No personalization via image analysis: Lacks AI or photo-based analysis to tailor treatment recommendations to individual scalp and hair types.
Fewer product options for women: Keeps focuses mainly on male pattern hair loss, with limited offerings specifically designed for women.

My overall rating

Keeps provides a telemedicine solution for hair regrowth, offering FDA-approved and off-label medications through a subscription model with access to online doctors. However, the platform lacks advanced personalization tools such as image-based scalp analysis and does not emphasize scalp health beyond basic regrowth treatments. The recent FDA warning about off-label topicals may also raise concerns for some users. Additionally, Keeps is primarily geared toward men, with limited options for women. Those looking for a more comprehensive, customized hair care solution may want to explore alternative brands.

Sixth Place
BosleyMD Hair Growth Supplements

Try Now

What I Love

Medicated and non-medicated options: Contains options for medicated Minoxidil or non-medicated natural products with DHT blockers.
Gender-specific formulations: Tailored versions for men and women, addressing unique hair loss patterns and nutritional needs.

What could be better

Focused on hair transplantation service: Bosley has been founded 50 years ago to provide hair transplantation services.
No personalization via image analysis: Lacks AI or photo-based analysis to tailor treatment recommendations to individual scalp and hair types.
Contains synthetic fragrance: Most noted products contain synthetic fragrances, including Hexyl Cinnamal, Linalool and Chlorphenesin – fragrance allergens that may cause dermatitis or allergic reactions.
Not a standalone solution for severe hair loss: It may be less effective without additional treatments or interventions for advanced hair loss conditions.

My overall rating

BosleyMD is a hair transplant service company that also offers a blend of medicated and natural solutions tailored for both men and women, including options with minoxidil and DHT blockers. However, the absence of AI-driven personalization and the inclusion of synthetic fragrances may limit appeal for some users.

A solid choice for men and women with mild to moderate hair loss looking for a brand with both medicated and natural options. Best for those seeking a structured based approach, but may not be ideal for users wanting a more modern personalized or fragrance-free regimen.

Seventh Place
Nioxin Hair Care System Kit

Try Now

What I Love

Multi-step approach: Each Nioxin system includes a cleanser (shampoo), scalp therapy conditioner, and a leave-in treatment—designed to work together to improve scalp environment and hair volume.
Cooling, cleansing experience: Contains peppermint oil and menthol for a refreshing, deep-cleansing effect on the scalp.
Available for different hair types: Option for a few tailored systems based on hair type (natural, color-treated, chemically treated, etc.).

What could be better

No personalization: One-size-fits-all formula that doesn't adapt to the underlying causes of hair loss (e.g., hormonal, nutritional, or environmental).
Limited clinical evidence: Clinical evidence is limited to Minoxidil lacking peer-reviewed evidence for effectiveness of the non-medicated Nioxin products and kits.
No active DHT blockers: Unlike Nutrafol or MDhair, Nioxin lacks ingredients like saw palmetto directly targeting hormonal hair loss.
May cause scalp dryness: Some users report dryness, tingling, or irritation—likely due to the menthol and alcohol-based components in the scalp treatment.
Results mostly cosmetic: For individuals not using recommended treatments like minoxidil, Nioxin may help improve hair volume and fullness, but is unlikely to reverse progressive thinning.

My overall rating

Nioxin Hair Care System is an old style multi-step approach to improving scalp health and enhancing hair volume. It's especially effective for those with mild to moderate thinning who want to boost fullness and scalp cleanliness with a tailored regimen. The peppermint-infused formulas deliver a refreshing experience, and the six system options accommodate a range of hair types and conditions.

Provides a low cost solution for those in early stages of hair thinning or looking to improve hair texture. Best for users who want to use minoxidil or users that are interested in a salon-grade, cosmetic boost. Not ideal for those needing a clinically proven hair regrowth solution.

Eighth Place
Spartan Root Activator Shampoo

Try Now

What I Love

Botanical-based formula: Features natural ingredients like peppermint oil, ginseng root extract, ginger root extract, and licorice root extract, known for their potential to nourish the scalp and support hair health.
Suitable for all hair types: Formulated to be gentle and effective across various hair types, including curly, straight, fine, and thick hair.
Free from harsh chemicals: The shampoo is free from sulfates and parabens, making it a safer choice for those looking to avoid these ingredients.

What could be better

Limited clinical evidence: While user testimonials are positive, large-scale, peer-reviewed clinical studies are lacking to substantiate the shampoo's efficacy claims.
Lacks options for oral supplements: The shampoo may not be sufficient for individuals experiencing advanced hair loss or conditions like androgenetic alopecia without additional treatments.
No medicated options: Does not offer FDA-approved medicated options like topical minoxidil.
Focused on men's hair loss: Does not offer hair growth solutions specifically formulated for women's hair loss.
Price point: Some users may find the shampoo to be pricier than other products on the market.

My overall rating

The Spartan Shampoos and topical scalp products offer a gentle, chemical-free approach to hair and scalp care. It stands out for its natural ingredients and suitability for all hair types, making it appealing for users seeking a clean beauty option in their hair routine. However, the lack of FDA-approved active ingredients and clinical backing may limit its effectiveness for users with moderate to severe hair loss. It also lacks comprehensive offerings such as supplements or medicated treatments, and the price may be a drawback for budget-conscious shoppers. While it can be a good supportive product, those seeking proven regrowth solutions may benefit from more robust, evidence-based alternatives.

Provides a low cost solution for those in early stages of hair thinning or looking to improve hair texture. Best for users who want to use minoxidil or users that are interested in a salon-grade, cosmetic boost. Not ideal for those needing a clinically proven hair regrowth solution.
