If your hair seems thinner than it used to be, you're not alone: 50 percent of women and 80 percent of men experience hair loss in their lifetime. But thanks to impressive hair loss treatments designed to thicken up your ‘do while also shielding against hair-thinning hormones, you can put an end to excessive hair fall and even help your hair grow back.
The More You Know
Since there are so many causes of hair loss, treatment results can differ person to person. And while they might not solve the issue altogether, board-certified dermatologist Dr. Dendy Engelman says individuals experiencing hair loss caused by factors like genetics, hormonal imbalances, or lifestyle choices can still benefit from hair loss treatments.
With so many different hair care products that claim to make your hair thicker and longer, finding one that actually does the trick takes time, research, and resources. Our PEOPLE Tested team dedicated nearly 1,000 hours to testing 20 formulas and uncovered which treatments were effective and worth the money.

Has a strong scent
After testing 20 hair loss treatments, this serum received top marks and was a clear winner. The dropper makes application super easy (you can apply it directly to the scalp) and the quick-drying formula isn't greasy so it doesn’t mess up your hairstyle or require extra washing. It absorbed easily and never caused irritation.
When testing this hair loss treatment, we noticed results within just one month of use. At the end of the testing period, our hair looked and felt a lot thicker, with new growth in some of the thinner areas as well as along the hairline.
Ingredients: Melatonin, minoxidil | Size: 2 ounces | Supply: 90 days
Star Qualities
Comes in 2-, 4-, and 6-month supplies
Costs around $15 per month
A little goes a long way
Saw results in 1 month

Hard to clean the cap after using
For another quick-acting hair loss treatment, we also loved the Minoxidil Foam from hers. This treatment comes in two-, four-, and six-month supplies and costs around $15 per month (the four- and six-month plans are even cheaper). It has a mousse-like consistency that is easy to work into the scalp and doesn’t interfere with styling, though there is a little bit of a sheen upon application.
After just one month of testing, we began to see a difference in our root growth. At the end of the testing period, our hair looked and felt a lot thicker and healthier. The foam also has a soothing and cooling touch that feels nice on irritated scalps. It's also scent-free, which is great for sensitive noses.
Ingredients: Minoxidil | Size: 2.11 ounces | Supply: 2-6 months
Star Qualities
Easy to target specific areas
Not greasy
Saw results after 2 months
Red Flags
Took longer to absorb and dry than others we tested
As much as we love the Advanced Trichology NutraM DHT Blocking Hair Serum for its application process, we found that this solution from Keranique was even easier to use. The serum features applicator caps with long nozzles that apply directly to the scalp, making it less messy and easier to target specific areas versus the entire head. It takes a little longer to absorb and dry than others we tested — around five minutes — but it doesn't dry greasy.
While we didn’t see results as quickly as some of the other formulas on our list, we still noticed improvements before the end of the testing period. After around eight weeks, our hair looked and felt a lot thicker and we noticed new growth in some of the sparser areas of our scalp.
Ingredients: Minoxidil | Size: 2 ounces | Supply: 60 days
Star Qualities
Quick to absorb and dry
Noticeable results after nine weeks
Improved bald spot hair growth
Red Flags
Messy application process
Not ideal for sensitive scalps
We tested this men's hair loss treatment on a bald spot, and some baby hairs started to sprout after nine weeks of twice-daily use. The scalp serum features a dropper that is relatively easy to use but can get a bit awkward when targeting a specific area, especially on the back of the head.
While it absorbs quickly, the serum is a bit runny which can make for a messy application process (this formula in spray form would have been much more ideal). Nonetheless, we were impressed by the regrowth and think it’s worth using over a longer period of time to maximize the benefits.
Coming Soon
This product is so popular that it sold out everywhere online — but, while we wait for the Nioxin treatment to come back in stock, we also found it hiding in this Hair Regrowth Kit for Men, which also comes with a fortifying cleanser and hydrating conditioner.
Ingredients: Minoxidil | Size: 2 ounces | Supply: 30 days
Best for Color-Treated Hair
Virtue Minoxidil Hair Growth Treatment

None!
If want a hair loss treatment that won’t interfere with your color-treated hair, try this regimen from Virtue. The kit comes with hair loss shampoo, conditioner, and a minoxidil treatment designed to support hair growth. Despite using the product just every two weeks, we still experienced growth along the hairline and our strands felt a lot thicker with less fall, too.
Ingredients: Minoxidil, gamma keratin, alpha keratin | Size: Varies, depending on product | Supply: 30-90 days
Star Qualities
Only takes seconds to absorb
Hair looked thicker and longer after 6 weeks

Messier application process
Whether you have experienced some hair fall or just want to thicken up your strands, this treatment from Rogaine is worth considering for its thickening benefits. The minoxidil-infused formula absorbs into the scalp within seconds and won't leave the roots feeling greasy or fade color-treated hair. It’s also one of the more efficient formulas we tried, as we noticed thicker and longer hair after just six weeks of use.
Ingredients: Minoxidil | Size: 2 ounces | Supply: 60 days

What to Know About Hair Loss Treatments
Ingredients
Dr. Engelman says to look for hair growth promoters like minoxidil, biotin, and keratin, as these can promote regeneration and strengthen hair. “Scalp treatments containing ingredients like caffeine or palmetto can also block the effects of dihydrotestosterone (DHT), a hormone associated with hair thinning,” she says.
All six treatments on our list contain minoxidil for growth, including our top pick for the best hair loss treatment, the Advanced Trichology NutraM DHT-Blocking Hair Serum (90-Day Supply). If you want something with extra oomph, the Virtue Hair Growth Treatment also has gamma and alpha keratin to strengthen strands and improve growth efforts.
Long-Term Use
While there are some styling products that can create the illusion of thicker, fuller hair, there is no such thing as an overnight solution for hair loss. When adding hair loss treatments to your regimen, Dr. Michael I. Jacobs, a board-certified dermatologist, says to use them consistently and long-term for best results.
With that said, if you are hoping to achieve some noticeable improvements in a shorter amount of time, we found that the Advanced Trichology NutraM DHT-Blocking Hair Serum made our hair thicker after just one month of regular application (though results were more noticeable after a longer testing period).
Underlying Causes of Hair Loss
Hair loss treatments can help improve thickness and length with regular use. However, Jacobs and Engelman both stress the importance of knowing the underlying cause of your loss and working with a medical professional to help address the concern.
“Hair loss can be the result of various factors, including hormonal fluctuations (such as pregnancy and postpartum), genetic predispositions, aging, stress, and seasonal changes,” says Jacobs.
Vitamin and mineral deficiencies can also lead to hair loss, especially if you have lower levels of iron, vitamin B12, vitamin D, and biotin. “Lack of these nutrients might cause hair thinning or shedding because they are essential for sustaining healthy hair growth,” says Engelman.
The More You Know
“Vitamin D affects the hair growth cycle by inhibiting the proliferation of hair follicle cells, and iron deficiencies can lead to anemia causing reduced oxygen delivery to the hair follicles and subsequent hair loss," Dr. Dendy Engelman says. Biotin is also important because it is essential for the production of keratin, which is the protein that makes up the hair shaft.
Additionally, Dr. Engelman says environmental factors “like exposure to pollutants or harsh chemicals in hair care products can damage the hair follicles,” which can result in hair loss over time.
By addressing the underlying causes of hair loss and using a treatment regularly in your regimen, you can begin to reverse the side effects and achieve desired results.
Behind The Scenes
We researched dozens of formulas before trying out 20 products in real-world conditions. We spent 12 weeks and 960 hours testing each treatment, carefully considering the application process, effectiveness, and overall results.
- Application: During the testing period, we considered the packaging and application process to get a general idea of convenience. We carefully looked at the applicator itself, plus the required treatment time, usage, and amount required to achieve desired results. We also noted the ease-of-use, consistency, and if the process was messy or not.
- Effectiveness: We marked down which formulas gave us the best results, how long it took to experience said results, and if the products lived up to their marketing claims. We also considered which ones worked best for thickening and which ones promoted growth.
- Overall Results: After considering the application process and effectiveness, we compared our notes and looked at the overall results of all 20 formulas. In addition to the hair growth outcomes, we also considered which formulas had the best absorption, were quick-drying, and didn’t leave any greasy residue.
Once our results were in, we compared and rated each product before narrowing down our selection to these six best hair loss treatments on the market.
