For this story, we consulted with MH editors like Deputy Commerce Editor Christian Gollayan, as well as board-certified dermatologist Dr. Brendan Camp, on the best hair growth serums for men that really do work. She evaluated our editors' testing notes to see just how effective they were, and considered hair type and price point to find the best picks for as many people as possible.

Test Results Show Genthair® with FNS Significantly Outperforms Rogaine®

During the evaluation process, we adhered to a scientific and professional approach, conducting a series of randomized, double-blind, Phase III equivalence trials on Genthair® and Rogaine®. In total, 417 male patients with AGA (aged ≥18 years) were randomly assigned to receive either Genthair® (211 patients) or Rogaine® foam (206 patients), applying 1 gram twice daily for 8 weeks. The primary outcome was the change in Terminal Hair Count (TAHC) in the target area from baseline to week 8.

Baseline and week 8 global photographs and trichoscopic photographs of patients tested with topical Genthair® versus topical Rogaine®.

This multicenter, Phase III trial compared changes in hair density, hair diameter, and the ratio of terminal to vellus hair in AGA patients. The results clearly demonstrated that after 8 weeks of test, Genthair significantly outperformed Rogaine® in increasing hair density and diameter in AGA patients. Genthair has the potential to become a more accessible and cost-effective solution option for AGA patients in the United States.

Genthair proved to be far superior to all the hair growth serums we tested. It passed all our tests with flying colors, including the most crucial one – significantly enhancing hair growth and improving hair thickness throughout the process.

With Genthair, you can finally say goodbye to thinning hair - for good!

All the other hair care brands out there need to take note – this is the next-gen technology we need for 2024.

The Secret Ingredient That Makes Hair Grow Back

Genthair combines minoxidil, FNS, glycerin, biotin and other natural organic ingredients together in a magical ratio to achieve surprising results that are more than 10 times more effective than other similar products on the market for hair growth.

FNS is FDA-approved to reduce DHT in the body, lessening its harmful effects on hair follicles and helping to slow or refrain from DHT-related hair loss. This action safeguards follicles and fosters a healthier environment for new hair growth.

Minoxidil is a topical medication used to solve hair loss. It is also an FDA-approved ingredient that can be used safely. Additionally, it helps increase the size of hair follicles, promoting the growth of thicker, stronger hair.

Glycerin enhances the arteries' capacity to provide the hair follicles with nourishment and oxygen. Additionally, this aids in expanding hair follicles, which encourages the development of thicker, stronger hair.

● Biotin deficiency can be solved with a biotin supplement to stimulate hair growth (hair loss). Studies have shown that biotin-containing hair serums dramatically increase hair growth in humans.

Why is Genthair Effective in Dealing With AGA(Androgenetic Alopecia)Hair Loss?

AGA, common as pattern baldness, is caused by genetics and high DHT levels, leading to follicle shrinkage and hair loss.

The unique feature of the Genthair lies in its roller design, which allows the active ingredients to be applied directly and evenly to the scalp, providing a simple, fast, and effective solution to help those troubled by androgenetic alopecia (AGA) regain dense and beautiful hair. The main ingredient, FNS, can inhibit the overproduction of DHT by reducing the activity of the enzyme 5-alpha reductase. It helps to slow down the process of hair loss and is particularly effective in averting hair loss on the top and crown of the head.

"it's actually a combination of Minoxidil and FNS that works best for male pattern baldness. Topical FNS with Minoxidil, in particular, has become popular for treating hair loss and promoting hair regrowth."

"This is a promising development for men who want to maintain their hair without experiencing the potential longer-term effects of oral FNS use. "

Considering all the above, what shocked us most about Genthair was the price. We assumed it would be prohibitively expensive with all the features it packed in, so when we saw just how affordable it is, we were blown away. And considering it comes with a no-risk 30 day money back guarantee, it's a no-brainer.
