There is an ever-growing market of hair growth products designed to fit every stage of thinning, loss, and budget constraints. Furthermore, the best hair growth products are no longer only for men, nor does it have to be a medicated formula that causes extreme irritation to sensitive scalps. But before you can find the best hair growth products to treat shedding or thinning, Dr. Michelle Henry, board-certified dermatologist says, "Determining the most effective hair regrowth treatment depends on identifying the underlying cause of hair loss."
Hair thinning and hair loss can be attributed to several causes, such as hair growth disorders, genetics, environmental impacts, severe illness, vitamin deficiencies and hormonal imbalances. Even COVID-19 causes hair loss, “The phenomenon is believed to be associated with physical and emotional stress related to the illness, as well as potential disruptors to the hair growth cycle,” explains Henry.
To better understand the causes behind hair loss and the best treatment options, we first spoke to our panel of hair regrowth experts including dermatologists, trichologists and a plastic surgeon. We took their insights on what to look for in the best hair growth products — and what to avoid — and the products they regularly recommend to patients and tasked our research team with finding the best hair growth products for women and men. During the testing phase, we paid special attention to how well the products worked, if those with sensitive skin experienced irritation, if any clinical studies proving product efficacy were available, cost, product type, and ease of use. Read on to find out which products made the cut as the best hair growth products of 2024.
Cost: $35 | Product type: Foam, shampoo, conditioner| Best for: Thinning hair | Key ingredients: Proprietary blend of proven hair growth helpers, peppermint, nettle, hops

For best results, use the Nioxin System Kit daily on scalp and hair.
Cost: $48 (Rogaine.com) | Type of product: Foam | Best for: Thinning and shedding | Key Ingredient: 5% Minoxidil
Rogaine is quite possibly the most recognizable and well-known brand when it comes to hair loss products, but there are two very good reasons for that: it's been around for three decades and its minoxidil products were the first to gain FDA-approval in the hair growth industry. As mentioned in the intro by our expert Dr. Taub, not only is minoxidil the oldest established remedy, and it is still the number one product used today by both men and women to promote hair growth. This 5% minoxidil foam penetrates the scalp to revive hair follicles and increase protein production in the cells to help regrow stronger, thicker hair. Even though Rogaine is often thought of as only having the best hair growth products for men, the company also makes great minoxidil-based products for women. Clinical studies showed the product helped regrow hair in over 80% of women in as little as 12 weeks, with visible results after continuous daily use after 24 weeks.
The formula is unscented, and unlike messy liquid drops, it comes in an easy-to-use aerosol foam that you only need to apply once a day — your hair can be wet or dry. The only downside is the side effects that come with medicated minoxidil hair loss treatments, including (while rare) irritated skin, rash, inflammation or soreness on the scalp at hair follicles, and headaches. If you are in panic mode over your hair loss, this might just be the best product for you, as long as you can dodge the rare, yet possible, side effects. That said, since it is a "medicated" solution, a trip to your doctor first to ensure it's safe for you to use may be a good bet.
Cost: $34 (Rogaine) | Product Type: Topical solution | Best for: Pattern baldness, all-over regrowth | Key ingredient: 5% Minoxidil, botanical extracts, alpha-hydroxy acid
Rogaine has been an industry leader in producing effective hair growth products for more than three decades. In fact, it was the first company to gain FDA approval for its products due to numerous clinical trials showing successful hair regrowth. The Rogaine Men's 5% minoxidil treatment is the number one dermatologist-recommended brand, and endless reviews singing Rogaine's praises are definitely a testament to the product. Of course, being a medicated minoxidil treatment, side effects such as skin irritation, rash and headaches should be considered before use.
You will need to consistently apply a full dropper of the product twice a day to the affected area to see results — if treating for hereditary hair loss you'll need to use the product indefinitely to prevent hair from returning to shedding and thinning. That all said, if fast, effective hair regrowth is your goal, this is one of the best OTC products out there.
"My hairline began slowly growing back upon using this product for two months," shared one reviewer, adding, "Incredible results and a lot of growth, definitely recommend."
Product type: Oil | Best for: Promoting density and hair regrowth | Key Ingredients: 30 essential oils and biotin | Cost: $12
Mielle Organics Rosemary Mint Scalp & Hair Strengthening Oil is not only a viral phenomenon, but it's also a favorite amongst Yahoo staffers, including myself. I truly love and use this hair oil and recommend it to all who ask me what they should use to help with hair loss and thinning. First and foremost, it's formulated with all-natural organic ingredients that are safe for all skin- and hair-types, yet is still incredibly effective, so I never have to worry about sending family and friends down a path riddled with side-effects and wasted time and money. Second, rosemary oil is hair-growth powerhouse that has been clinically proven in multiple studies to work as well as minoxidil. In fact, one major study found that rosemary oil not only worked as well as minoxidil at promoting hair growth, the participants in both the minoxidil control group and the rosemary control group experienced the same amount of hair growth. The study also found that participants in the rosemary group stuck with the treatment longer than the minoxidil group.
The oil works by creating an all-over healthy scalp environment for hair to grow, starting with nourishing the scalp, hair follicles and hair shaft root to tip while also reducing inflammation and increasing vasodilation, which is a fancy word for opening blood vessels and promoting blood flow and circulation, which has also been proven to help promote hair growth. The most important thing you must do to see results is stick with it for at least a few months, with application at least every other day. This is the case for all hair growth products; hair can only grow so fast. If you would like to learn more about hair oils, read our round-up on the best hair oils.
Pro tip: For those with fine hair, rub one to two drops between just the fingertips and massage straight into the scalp for at least a minute. This will minimize excess oil transfer from your palms to hair and leave your hair with extra volume. While some feel the rosemary and mint scent is a little too strong, I love it!
Cost: $24.50 | Product type: Shampoo | Best for: All-over regrowth | Key ingredients: Biotin, caffeine, saw palmetto
Keeps thickening shampoo is designed to help stop hair from thinning and restore it from the first wash. If this is your only hair loss treatment, great; if you're also using another hair loss treatment, this can help enhance your results. The specially formulated shampoo for thinning hair uses biotin, caffeine, green tea and saw palmetto to help stimulate your scalp and gently cleanse it in the process. While you're likely not buying a shampoo for the smell alone, it doesn't hurt that it has an invigorating minty scent. There's also a coordinating thickening conditioner. Shared a five-star reviewer: "I have noticed that my hair has become stronger and thicker since I started using this shampoo. It also feels softer and more manageable, which is a huge plus."
Something to know: While biotin has long been used for hair growth and can be found as the key ingredient in products from hair serums and oils to supplements and shampoos, there are studies that say more research is needed to declare biotin as a silver bullet answer to hair regrowth.
Cost: $19 per bottle at Hers or $25 for two bottles at Amazon | Product type: Shampoo | Best for: All hair types, especially those with thinning and loss | Key Ingredients: Biotin, saw palmetto, pumpkin seed oil
I was skeptical that a shampoo alone could make a difference, but by the end of the bottle, I was so pleasantly surprised I bought a second bottle. And while I did use the rosemary oil in conjunction with this shampoo, what made me a believer was how much thicker my hair felt, after just a few weeks. What makes this shampoo effective is its trifecta of hair growth ingredients: Biotin, saw palmetto, and pumpkin seed oil. Biotin, while it can be found in nearly every hair growth product, its not as well backed up with clinical trials as say minoxidil or rosemary oil, but that said, a few studies have found biotin to promote significant hair growth in people, hence it being so prevalent in hair and nail growth topicals and supplements. Saw palmetto has been found in clinical studies to reduce hair shedding and improve growth as well as improve scalp health. I can attest to all of this and now use Hers Tripple Threat shampoo every few shampoos to maintain scalp health.
Cost: $88 or $75 with a subscription | Type of Product: Serum | Best for: Hair thinning and shedding | Key Ingredients: Proprietary blend
Even though Harklinikken's award-winning Hair Gain Extract is pricey, each bottle is customized specifically for you. In order to get your hands on a bottle of this serum, you'll start by filling out a brief questionnaire on the Harklinikken website that covers your hair type, hair thinning and shedding concerns, current and past medical conditions, diet and exercise, and any past procedures, illnesses or stressful life events that could have lead to your thinning or loss. After completing the survey, a tailored hair treatment regime is created that includes product recommendations for the serum, shampoo and conditioner (optional) that will improve the condition of your scalp, strengthen the hair at the roots, re-engage hair follicles, stimulate regrowth, and prevent future hair loss.
Harklinikken comes highly recommended by one of our experts, board-certified plastic surgeon Dr. Glenn Vallecillos, who tells us, "In our practice, we have seen great success with the Harklinikken line, which addresses specific types of hair loss by offering customized, targeted and responsive treatments, based on the patient's unique history, scalp profile and hair loss circumstances."
You can purchase one bottle at a time for $88 or opt into auto-replenish and save 15% off the retail price ($74.80).
Cost: $64 | Product type: Serum | Best for: Hair thinning and shedding | Key ingredients: Curcumin stem cell extract, red clover, mung bean
One of the most common forms of hair loss ior women is female patterned hair loss (FPHL), marked by a slow decrease of hair density on the scalp. According to board-certified dermatologist Dr. Jodi LoGerfo, about 50% of women will experience this at some point. “This slow and steady loss of hair is caused by the action of the hormone dihydrotestosterone (DHT),” she explained.
Vegamour’s GRO Hair Serum is a game-changer for thinning hair. Its plant-based formula prioritizes natural ingredients for major results. Curcumin stem cell extract, also known as turmeric and red clover come together to block DHT production. Mung bean is another important ingredient on the roster because it contains copper. Copper strengthens the hair follicle, which in turn decreases shedding.
According to the company’s study, 52% of clinical trial participants saw more density and 76% saw less shedding. You can count on seeing results within three months and can expect to see maximum results after four months. One bottle costs $64 and lasts about a month. If you’re hoping to cut costs, you can subscribe and receive the product once a month for a 23% discount.
Product type: Supplements | Best for: Promoting hair growth and density | Key Ingredients: Ashwagandha, collagen peptides, maca, saw palmetto, antioxidants, horsetail | Cost: $88 at Nutrafol; $79 for monthly deliveries; $224 for three month supply
Nutritional supplements work internally to support hair cell production. Nutrafol is a natural, physician-formulated supplement that promotes hair growth and overall wellness. The products use a blend of vitamins, minerals, botanicals and antioxidants to tackle the six root causes of hair loss: hormones, stress, lifestyle, metabolism, nutrition and aging. There's also a mix of DHT blockers, including curcumin, saw palmetto, resveratrol and horsetail to help reduce thinning and hair loss. Other science-backed ingredients, such as ashwagandha, marine collagen peptides and keratin (the primary protein in hair), are included as a way to strengthen hair follicles and encourage growth.
We especially love that the company has made research a priority. In a clinical trial, women taking Nutrafol supplements had longer, thicker hair after six months and improvements in overall hair growth, volume and color. Many of the participants reported improvements in other aspects of their well-being, including stress levels, anxiety, sleep quality and skin health.
Cost: $88 | Product type: Supplements | Best for: Thinning and hair loss | Key ingredients: Saw Palmetto, biotin, vitamins A, C, D; ashwagandha exomes, Irish moss peptides, pea sprout extract
While minoxidil is considered a gold standard in hair growth products, it's not for everyone. A safer yet still effective option is Nutrafol's all-natural approach to hair regrowth: supplements and a topical serum. The supplements work from the inside out to promote cell turnover and healthy cell production, while the serum nourishes the scalp and hair follicles to create an optimal environment for hair regrowth. The ingredients in both products are all-natural yet proven effective for improving hair density and growth, including some ingredients like the hard-to-pronounce ashwagandha exosomes, Irish moss peptides, pea sprout extract, biotin, and the real star here for men: saw-palmetto, which in addition to being effective for hair growth, it has also been found in clinical studies to be beneficial for men's prostate and urinary tract health.
Cost: $600 (Money back guarantee) Product type: Laser cap | Best for: Reversing thinning and growth from the hairline to the crown
The iRestore Essential Laser Hair Growth System employs an FDA-approved treatment for hair growth: low‐level light therapy. The laser cap promotes blood flow and new cell growth by stimulating mitochondria and promoting protein synthesis. Low‐level light therapy has been found in clinical studies to help encourage hair growth over time with regular use — every other day for six months. In an iRestore independent lab study, there was an average hair count boost of 43.2% over four months in all of its participants - which is likely why the company offers a full money-back guarantee.
Light therapy is ideal for those who prefer non‐invasive hair growth options and want to avoid the ongoing expense of hair growth products; the laser cap requires a one-time purchase only. All you need to do is wear the laser cap for 25-minute intervals every other day. You can use it with other hair growth treatments, and the best part is the company will give you your money back if you don't notice results within six months.
If you're tired of watching your hair thin and shed but overwhelmed by all the available options, we're here to help. We’ve broken down some key factors to consider when finding the best hair growth product for your unique needs.
Type of hair loss: To find the correct product, you’ll want to get familiar with the type of hair loss you’re up against. Genetics, stress, hormones, diet and after-effects of Covid are all common causes of hair loss. If you’re not quite sure what type of loss you’re working with, you may want to consult a dermatologist for further clarity.
Hair growth supplements vs. topical hair growth products: When considering the type of product you’d like to use, look at your daily routines. Are you someone who only shampoos your hair a few times a week? Then perhaps a hair growth supplement would work better than a shampoo for you. Do you have thicker hair that can easily absorb oil without looking greasy? Then be sure to check out the oil and serum treatments we’ve included in our top picks. Do you struggle to remember to take medication? If so, an oral supplement may not be the best for you.
Budget: Money is a major factor in considering treatment. Figure out how much you’re comfortable spending monthly on a hair loss formula before making a decision. Plenty of our picks are budget-friendly, so we are confident you’ll be able to find a formula that fits your needs.
Prescription vs. non-prescription for men and women: You’ll notice we will use gendered language throughout this article due to certain products crafted with a gender-specific solution: for women, you will see 2% to 5% topical Minoxidil solutions, but only 5% for men. When it comes to prescription-only hair loss medications such as Finasteride, Dr. Henry tells AOL, "Finasteride and dutasteride are 5-alpha-reductase inhibitors that are often used in the treatment of male hair loss. Both inhibit the conversion of testosterone to DHT, decreasing 5-alpha-reductase and decreasing the effects DHT has on the hair follicles." She also notes that, "treatment with Finstraride in women should be avoided in those who are pregnant or may become pregnant, because the drug is teratogenic, which means it could affect a male fetus. We use both of these medications in practice." As always, we recommend discussing any new treatments with your healthcare provider before starting.
Before testing products, we spoke with our panel of hair loss experts including dermatologists, plastic surgeons and trichologists to learn what products actually work, what key ingredients to look for and what to avoid (namely, products that contain alcohol and fragrances that can damage and dry hair follicles). We then took their feedback and researched 23 different hair loss brands and tested each of their top-rated hair loss products. Our team looked for innovative products that were backed by studies, were effective, and affordable. We paid special attention to products developed by hair care doctors or experts.
Do hair growth products really work?
Yes, but the results depend on the condition causing the hair loss and the type of product used. “You have to remember, thinning hair may need medical treatment,” explains Dr. LoGerfo. She continues by emphasizing that you want to tend to your scalp health first to set the best foundation for hair growth.
Another one of our experts, clinical dermatologist and trichologist Dr. Andy Goren echoes the importance of scalp health. Dr. Goren also spoke to AOL about the importance of early detection of hair loss. He explained that most patients only notice hair loss when about 50% of hair has already been lost on a particular area of the scalp. Even with a genetic predisposition, early diagnosis can lead to treating hair loss successfully before it is visible. So, if you notice you’re shedding just a bit more than usual, get checked out by your doctor ASAP. From there, you’re more likely to succeed with your chosen hair growth products.
How long does it take to see results from hair growth products?
This varies based on the product; however, many products we included in our picks offer visible results within two to three months. If getting immediate volume is important, you could try a shampoo for thinning hair that also adds volume and the appearance of thicker hair instantly. The key to seeing results is staying consistent. Make you follow the directions for use to ensure you will see results, and be patient since this will take time, but you should start seeing improvements in your scalp health — less irritation, reduced itchy and flaking — within a few weeks.
Are hair growth products safe for everyone to use?
It is important to remember that some hair growth products have limitations on who can use them. For example, many of the formulas we included on our list, especially those containing Minoxidil, are gender-specific since your genetic makeup dictates how well your skin can handle certain ingredients. Regardless of the product you choose, test it first on a small area of your scalp to make sure you don't experience irritation.
