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 created MDhair to deliver what I believe is the most effective, personalized approach to hair regrowth. I've tested the leading hair growth products on the market and compared them head to head.
Last updated: 2/27/2025
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.
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.
I researched and evaluated eight leading hair regrowth solutions: MDhair, Sons, Regaine, Numan, Hair+Me, Scandanavian Biolabs, Viviscal, and Watermans.
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.
Sale: Get up to 60% off your first kit

My verdict
Sons has carved out a strong position as the UK's leading men-only hair loss platform, and their access to licensed, clinically proven treatments is a genuine advantage. The subscription model is convenient, pricing is competitive, and the results guarantee shows confidence in their approach.
That said, the platform is exclusively for men, which rules out a large portion of people dealing with hair loss. Ingredient transparency has been questioned by independent reviewers, and the reliance on certain medications means potential side effects that not everyone will be comfortable with. There is no scalp imaging, no AI-driven personalisation, and fewer product options compared to a more comprehensive system like MDhair, which offers dermatologist-designed, customised treatment kits with free scalp analysis and 24/7 medical support.

My verdict
Regaine is one of the most established hair loss treatments in the UK, and its active ingredient, minoxidil, has genuine clinical backing. It is a solid option for men and women looking for a widely available, pharmacy-grade solution.
However, the product has notable limitations. It relies on a single active ingredient with no personalisation, requires indefinite twice-daily use, and comes with common side effects like scalp irritation and initial shedding. The treatment does not include any diagnostic tools, scalp analysis, or medical support to tailor the approach to your individual needs.

My overall rating
Numan offers both medicated and non-medicated options, including access to approved treatments, providing flexibility for men dealing with hair loss. This can be appealing for users who want advanced solutions alongside more natural or supportive care. However, the process to get started is not user-friendly - it involves a complex consultation and may take up to three business days for an initial appointment.
The platform also feels more like a generalist health site, focusing heavily on weight loss and sexual health, rather than being tailored to hair loss. Personalization is limited, with fewer ingredient options and no dynamic adjustment features.
The sign-up process includes a long health questionnaire and lacks any automated scalp image analysis. Additionally, some medications offered are off-label and not FDA-cleared for topical use. Overall, while Numan provides legitimate treatment options, it lacks the ease of use, personalization, and specialization found in platforms like MDhair.

Hair + Me provides both medicated and non-medicated options, including access to approved treatments, which is a trusted approach for male pattern hair loss. This flexibility allows users to select an approach that aligns with their preferences and comfort level. However, the process to get started is not intuitive - it requires a consultation and involves a somewhat complex and lengthy signup.
Personalization is limited compared to services like MDhair, with fewer ingredient variations and no dynamic treatment adjustments. The onboarding experience includes a very long health quiz and lacks automated scalp image analysis. Users should also be aware of potential risks, as the service offers oral treatments which may carry significant side effects.

My overall rating
Scandinavian Biolabs stands out as one of the better, plant-based options for hair loss. The clinical trial data is genuinely impressive for a drug-free product, the formulations are clean, and the 150-day guarantee removes much of the financial risk.
However, the lack of clinically proven active ingredients means it may fall short for anyone with moderate to advanced thinning. The premium pricing also puts it in direct competition with more comprehensive solutions. There is no personalisation, no scalp analysis, and no access to medical professionals through the platform.
For users seeking a natural, drug-free starting point, Scandinavian Biolabs is a credible choice. But for those who want a dermatologist-designed, personalised system that combines clinically proven ingredients with scalp diagnostics and ongoing medical support, MDhair provides a more complete and targeted solution at a comparable or better value.

My overall rating
Viviscal is a science-backed supplement for people seeking to improve hair density and reduce thinning without using medicated ingredients. Its standout feature is the AminoMar™ marine complex, which is clinically shown to promote stronger, healthier hair. With additional nutrients like biotin and vitamin C, Viviscal supports hair from within by targeting internal nutritional factors. However, it's not a personalized solution and does not address hormonal causes of hair loss. It also lacks a topical component, which could limit its efficacy compared to more integrated treatment systems. Because it contains fish-derived proteins, it's not suitable for all diets.
Viviscal is a solid, clinically supported option for general hair thinning, especially for women. But for those with hormone-related hair loss or seeking an all-in-one plan (oral + topical + customization), other solutions may offer more value.

My verdict
Watermans has built an impressive UK brand with strong retail presence, affordable pricing, and a clean ingredient list. The Queen's Award recognition and over 5 million bottles sold speak to genuine consumer demand and satisfaction, particularly among users looking for a natural, daily-use shampoo to support overall hair health.
However, it is important to set realistic expectations. Watermans is a cosmetic haircare brand, not a clinical hair regrowth treatment. It does not contain MHRA-licensed active ingredients, offers no personalisation, and provides no access to medical professionals. For users dealing with general thinning, breakage, or scalp health, it can be a solid addition to a routine. But for clinically meaningful hair regrowth, especially in cases of hereditary or hormonal hair loss, a dermatologist-designed, personalised system like MDhair that combines proven active ingredients with scalp imaging and medical support will deliver more targeted and measurable results.
After researching and comparing all the options, it’s clear that MDhair stands out as the best choice for hair regrowth. Its customized approach, dermatologist backing, and clinically proven results make it the most effective option.
If you’re looking for long-lasting, noticeable results with a formula designed for your unique needs, MDhair is the best investment for your hair regrowth journey.
