The 11 best hair products for thinning hair of 2025, according to experts

Product type: Foam | Key ingredients: Minoxidil, botanical extracts, alpha-hydroxy acid | Best for: Men with thinning hair and loss

Rogaine has been an industry leader for more than three decades. And for good reason: It works. The Minoxidil Foam for men features a 5% minoxidil topical solution that has been approved by the FDA to treat pattern hair loss, and it has numerous clinical trial results to prove its worth. The product works by boosting hair follicle activity and hair protein production. This doctor-recommended product also contains botanical extracts and emollients to help maintain a healthy, conditioned scalp, while the alpha-hydroxy acid promotes natural skin exfoliation to help keep follicles open. 

One happy customer said, "Be patient, it works! After just four months, I'm seeing noticeable improvement. The results are worth the 2x daily applications and I've noticed I feel better about myself and restored confidence."

Product type: Foam | Key ingredients: Minoxidil | Best for: Women with thinning hair and loss

When it comes to medical-grade hair growth products for women, it's going to be hard to top Minoxidil, which is one of three FDA-approved hair growth treatments and the only one safe enough for women. If you want to break out the big guns, the experts say that minoxidil is the way to go. Taub told us, "The oldest established remedy and still one that is used quite a bit is topical minoxidil." Obviously, though, it is a major medication and has potential side effects that need to be evaluated with each person, she added. This topical solution and medication is the key active ingredient in Women's Rogaine. (If natural methods are more your thing, be sure to select something else from our list.) 

When used daily, Rogaine is clinically proven to boost hair follicle activity and hair growth for improved hair density. One user claimed that it's life changing: "I have been using this product for three months and I’m genuinely thrilled with my results! My scalp has so much new hair growing in, for the first time in years I can part my hair however I want without fear. All my thin spots are filling in. Even my husband keeps commenting on how much thicker my hair is. This product is 100% worth the money!!"

Product type: Shampoo, conditioner, serum | Key ingredients: Proprietary blend of proven hair growth helpers, as well as peppermint and tea tree oils, saw palmetto | Best for: Thinning hair

Nioxin offers a three-hit combo approach to thinning hair and loss with its hair care "system kits." The company offers six different system kits, each tailored for specialized needs, including products to help with natural hair, bleached hair and color-treated hair, as well as thinning hair or severe hair loss. This bundle of products is formulated for fine to normal hair with progressed thinning, and is a great choice for someone wanting to take an aggressive approach to hair restoration. The first step in the kit is the shampoo, which is especially great for removing environmental and product buildup, as well as sebum, which is linked to increased dihydrotestosterone (DHT), a naturally occurring hormone that also stifles hair growth and follicle health. The second step is the conditioner, which moisturizes the scalp and strands, strengthing hair and preventing breakage. The final step is the all-important serum that stimulates the scalp, promoting blood flow and new growth.

One fan shared that the kit greatly improved their hair's texture and manageability. "After 35 days of use, I see obvious improvement. The short, fine hairs at my hairline (particularly at the temples) never seemed to grow until I started using Nioxin. Now it’s nearly filled in."

Product type: Oil | Key ingredients: Rosemary and mint essential oils, biotin | Best for: Thinning hair

Don't let the inexpensive price tag fool you, Mielle Organics Rosemary Mint Hair Strengthening Oil really works! Thanks to the mint and rosemary, which are clinically proven to promote hair growth. The endless before and after photos are truly inspiring. Not only is it a customer favorite, including 44,000 5-star reviews, but it's loved by many Yahoo staffers, including our former Senior Health Editor, April McCormick, who insists, "This oil really works! The shining star is the rosemary oil that is clinically proven to help promote hair growth. The consistency of the oil is also divine — not too thick or thin." This oil promotes blood flow, nourishes the scalp and follicles, fixes splint ends and even tames flyaways after styling. One reviewer said, "5 stars because this has REVOLUTIONIZED my life!"

Pro tip: If you find this is too oily for your fine hair, add a few drops to conditioner, leave it in for a few extra minutes then rinse.

Product type: Shampoo | Key ingredients: Saw palmetto, Hims's proprietary blend of DHT blockers | Best for: Male pattern baldness and thinning

Men are more likely to experience hair loss due to hormone-driven differences between men and women. A leader in the men's health and wellness industry, Hims designed its Thick Fix Thickening Shampoo to cleanse away excess sebum to allow new follicles to grow strong and healthy; that, in combination with DHT-blocking saw palmetto, immediately increases hair volume.

Thick Fix features a refreshing eucalyptus scent and easily lathers to permeate the scalp for a seriously deep clean. One reviewer said, "For years, I have fought hair loss and thinning hair. Within a week of using this product, I felt like I was finally winning that fight." 

There's also a Power Pack ($60) if you want to go extra hard at your thinning/loss issues.
