Hair Loss Product Reviews & Rankings
This section holds our individual product reviews and our ranked buying guides: minoxidil brands, hair supplements, DHT-blocking shampoos and laser devices. Each review looks at what a product actually contains, what the published evidence says about those ingredients or that device, what it costs to keep using, and who it is and isn't a good fit for.
If you are shopping for a category rather than a specific product, start with a ranking: the best minoxidil for men and women, the best laser caps, or the best hair supplements for men. If you already have a brand in mind and want something cheaper or better supported, our Nutrafol alternatives and Rogaine alternatives guides compare the options side by side.
Rankings weigh clinical evidence first, then safety, value for money and ease of use. We explain how we score products, and how affiliate relationships are kept out of the rankings, on our methodology page.
