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.
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.
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 four leading hair regrowth solutions: MDhair, Hers, Nutrafol, Rogaine, Vegamour, Moerie, Viviscal, and Sugarbear. 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 overall rating
Hers Hair OTC Regrowth Treatment delivers a convenient and affordable option for women experiencing early-stage hair thinning, leveraging the clinically proven active ingredient minoxidil. However, the product lacks personalization, or nutritional support, and doesn't address multiple root causes of hair loss such as DHT or stress. It's a straightforward solution for minoxidil-responsive thinning but may fall short for users seeking a more holistic or customized approach.
A simple entry-level topical treatment for women with mild to moderate hair thinning. Best for those who want an affordable, OTC solution with proven effectiveness—but not ideal for those seeking long-term, multi-factorial support or personalized care.

Nutrafol is a good choice for those who prefer an all-natural, internal approach to hair growth and are ready to take four capsules a day for the long term.Its blend of vitamins, minerals, and botanical extracts supports overall hair health without harsh chemicals.
However, at $79 per month, it’s pricey, and since it’s a supplement, results take time. Unlike other treatments, it has a very limited choice of topical products for direct scalp application. Customization is also limited. While it can improve hair wellness, it works best when combined with a targeted treatment for faster regrowth.

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.

My overall rating
Moérie’s Ultimate Hair Growth Set offers a chemical-free approach to hair care for those focused on improving scalp and hair health with naturally derived ingredients. Its appeal lies in the inclusion of minerals and botanicals, along with a full product lineup. However, it lacks several key components needed for users with more advanced or hormonally driven hair loss, such as DHT blockers, FDA-approved treatments, or access to professional medical guidance. The limited clinical backing and variable results may also be a concern for users seeking reliable, evidence-based regrowth solutions.
An option for those in the early stages of hair thinning or seeking a clean, salon-like boost to hair strength and appearance. Not ideal for users looking for clinically proven or medical-grade hair regrowth solutions.

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 overall rating
Vegamour GRO Hair Serum is a clean, topical alternative to traditional medicated hair treatments. Its plant-powered formula is well-suited for users who want a gentle, hormone-free approach to improving scalp health and supporting early signs of hair thinning. The serum absorbs quickly, leaves no residue, and aligns well with a natural beauty lifestyle. However, it may fall short for people with significant or hormonal hair loss and lacks robust clinical backing compared to some competitors, and raises concerns for people sensitive to bergamot oil. It's also not part of a personalized or AI-guided program, which limits its precision for individual needs.
Best for early-stage hair thinning and those seeking a natural, topical-only solution. Pairing with oral supplements or medicated treatments may be necessary for more advanced or hormone-related hair loss.

My overall rating
Sugarbear Hair Vitamin Gummies are a "fun and tasty" option for people looking to supplement their diet with hair-friendly vitamins. Their vegan formulation and appealing taste make them especially popular among younger users and those new to supplements. However, they're not the best fit for people experiencing hair loss. They lack powerful ingredients like DHT blockers, personalized formulations, or clinical data to support real regrowth. For $30–$35 per month, they're more affordable than other premium options, but you lose in efficacy from what you gain in taste and convenience.
The bottom line is that it is fun and affordable but not a strong contender for treating hair thinning or shedding independently. The use of the synthetic color Blue-1, which will soon be banned from use in the US, raises health concerns.
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.
Here’s how they compare:
