Hair thinning can happen to anyone, no matter their gender or age.
Luckily, there are certain products and ingredients out there that can help slow down or even reverse the hair thinning process and keep hair looking thick and healthy.
From prescriptions to over-the-counter (OTC) treatments, we dove into the options out there, so you can select the best product for your needs.
While it may feel like you’ve been dealt a poor hand, hair loss is surprisingly common.
It can occur due to:
You can find the best treatment option by exploring the cause behind your hair thinning with your doctor or dermatologist.
When searching for products for hair loss, it’s a good idea to start with the ingredients.
Some of the most effective ingredients for hair growth include dihydrotestosterone (DHT) blockers and inhibitors. DHT is a molecule derived from testosterone that’s responsible for hair loss.
There are only two ingredients approved by the Food and Drug Administration (FDA) for hair regrowth. Both are DHT blockers. These two ingredients can be found in various OTC and prescription medications.

They are:
Minoxidil is thought to work by partially enlarging hair follicles and lengthening the hair’s growth phase. Finasteride works by decreasing the amount of the hormone dihydrotestosterone (DHT) in your body.
Here are a few other ingredients for hair growth:
While there are lots of products out there with ingredients that companies claim to support hair growth, not all of them are supported by scientific research.
We looked for products and treatments from reputable brands with the most significant research behind them and the most effective ingredients.
We also looked carefully at customer reviews, choosing only products that real customers find useful in their personal experience.
Rogaine is an FDA approved treatment for hair loss that contains minoxidil. It generally contains a stronger percentage than other OTC brands, and it’s one of the most popular and well-known for good reason.
As a 2019 study explained, Rogaine works by increasing hair growth and reducing hair loss, making it great for female and male pattern baldness. It can also be used for alopecia and eyebrow density.
The brand offers a satisfaction guarantee policy, which means you’ll get a full refund if you use the product daily for 130 days and aren’t satisfied with the results. For best results, it’s recommended to use Rogaine for at least 3 to 6 months to see results.
When it comes to reviews, a majority of reviewers note that their hair grew in spots where their scalp was visible before. On the other hand, a few 1-star reviews have to do with allergic reactions, scalp sensitivity, no changes, or even increased hair loss.
It’s important to note that minoxidil may cause initial shedding, but this effect will likely decrease with use.
Hims offers a variety of subscription products for male hair loss that include either minoxidil, finasteride, or both combined. The company also offer a selection of vitamins, like biotin gummies.
According to a 2015 study of 45 men, 84.4 percent of participants with androgenetic alopecia maintained good hair density after initial treatment when using a topical minoxidil-finasteride combination.
Using the two ingredients simultaneously helped the participants of the study maintain denser hair.
Another 2015 study showed that 94.1 percent of men who used both ingredients at once showed significant improvement, while only 80.5 percent saw improvements with finasteride alone, and only 59 percent saw improvements with minoxidil.
After setting up a HIMS account, customers can book an online consultation with a licensed medical professional to find out which products are best for them.
While Hims, Inc. has an A+ rating with the Better Business Bureau, some customer reviews are less than stellar. The company’s overall 1.33 average rating out of 5 stars has to do with sexual dysfunction products, as well as complaints of being charged for products after notifying the company of the desire to cancel.
When it comes to hair products specifically, customers noted the effectiveness of the minoxidil and finasteride combination in particular.
Hims also offers a full money-back guarantee within 90 days. Canceling a subscription can take 48 hours and must be done at least 2 days prior to the next month’s charge, or you’ll be charged for an additional month.
Keranique is another treatment that contains FDA approved minoxidil, clinically proven to treat female pattern baldness. It comes with a handy sprayer, so you can apply it topically to thinning areas on the scalp.
Keranique only has formulas with 2 percent minoxidil, which is less than some other brands. Still, it’s meant to be applied to the scalp twice daily.
According to the company’s website, the product currently averages 4.8 stars out of 5. Many reviews indicate that customers are happy with the results of the product.
Keeps is similar to Hims in that it offers customizable subscription plans that contain minoxidil, finasteride, or both combined.
In addition, Keeps offers products with ketoconazole, an antifungal medication and generic version of Nizoral that’s used off-label for hair loss.
You can choose the products you want to use right away or fill out a questionnaire about your hair loss, medical history, and lifestyle. You can also include photos if you want to.
Once a doctor reviews your information, they’ll suggest a treatment plan for you. Products come as tablets, foams, and serums.
Most product reviews are positive, while negative reviews have to do with people having difficulty canceling or the company incurring charges after they canceled.
Ketoconazole can cause serious side effects. Contact your doctor if you have redness, pain, swelling, or tenderness after applying the medication.

The Better Not Younger Hair and Scalp Duo includes a hair and scalp serum with ingredients like niacinamide, caffeine, and gotu kola. It also boasts a scalp massaging applicator to help distribute the serum.
While it’s on the higher end of our pricing scale, you’re essentially extending the bang for your buck by getting two products in one set.
According to the Better Not Younger website, 97 percent of women using the serum daily for 8 weeks in independent consumer trials saw improvements in hair quality and hair fall.
The action of massaging the scalp with the scalp massaging applicator may provide additional benefits.

The first thing to consider in hair growth products is the active ingredient list. Look for natural ingredients that are known to help with hair loss, such as biotin, collagen, niacin, and caffeine.
Also keep an eye out for an FDA approved sticker to ensure that the product has been thoroughly tested.
Not all products that claim to help with hair growth are safe or effective. Avoid brands that don’t have an FDA approval or that don’t have many customer reviews.
While using hair growth products and supplements can have plenty of benefits, there are a few negatives, too.
Always follow the specific instructions given on the box or bottle. Here are a few general tips to help you make the most out of your hair growth products:
Depending on the sensitivity of your scalp and hair, some ingredients and products may actually do more harm than good.
If you plan on trying a hair growth supplement, be sure to check the list of ingredients, as many supplements contain ingredients that can cause side effects.
These side effects can include:
On the other hand, some hair growth products may result in unexpected benefits, like:
Be sure to check with your doctor before using any new hair growth product. If the product is topical, it’s best to do a patch test before use.
Hair growth products don’t work instantaneously. Most products will start to work within a few months.
Hair follicles take a few weeks to become stimulated by your product, and after that, it will take a month or two before you notice new hair growth.
While physical hair growth may take several months, most products will improve the appearance of your hair’s thickness within a few weeks.
While serums work from the outside-in, supplements work from the inside-out. Ideally, you’ll be able to use both types of products at once for optimal results.
There aren’t yet studies that show the benefits of serums as opposed to supplements. However, in general, topical treatments tend to work quicker than oral treatments.
In addition to using hair growth products, there are a variety of other methods you can take to improve the thickness and health of your hair.
It’s also important to:
If you’re looking for a hair growth boost, these products may just do the trick. While many can help improve hair health, they rarely get to the root of the problem.
Always talk with your doctor, so you can find out the medical reason for your hair loss and a more targeted solution.
