The best hair growth products of 2024, according to experts

Watching your hair begin to thin or shed can be an extremely stressful experience. Thankfully, you can not only reverse thinning and shedding, you can prevent future hair loss and heartache. There is an ever-growing market of hair restoration 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 product for your needs, you need to understand the root cause of the loss. (Pun intended!) 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 Dr. Michelle Henry, board-certified dermatologist. So, if you’ve had COVID and experienced hair shedding or thinning two to three months later, COVID could be the culprit.

To better understand the causes behind hair loss and the best products to rectify various conditions, with input from our expert panel, we tasked our research team with finding the best hair growth products for women and men. Our team researched 23 companies treating hair loss and interviewed nine medical experts to come up with our top picks for the best products that target hair loss. When making our selections, we paid special attention to cost, product type, and ease of use. Read on to find the best hair growth product to fit your specific needs.

Best hair growth products of 2024

Product type: Foam | Key ingredient: 5% Minoxidil | Best for: Hair regrowth

If you want to be very aggressive about restoring your thinning hair to a thick, full, happy head of hair, look no further than the Rogaine 5% Minoxidil Unscented Foam

This hair regrowth treatment is designed to stimulate hair follicles, which is essential to hair regrowth. "Minoxidil is thought to prolong the anagen (growth) phase, decrease the telogen (resting) phase of hair follicles and increase the size of follicles that have already been miniaturized, enabling hairs to become thicker and grow longer," explains Dr. Henry. We were especially thrilled with the topical solution's promising clinical trials – according to Rogaine, 80% of women saw hair growth begin within 12 weeks and substantial growth after 24 weeks of daily use. This hair loss treatment is available in two different formulations; this one is formulated for women, but you can also get a product formulation specific to men

Keep in mind that the company recommends starting with a three-month supply since it will take at least three months to see results. 

Pros
  • Stimulates hair follicles essential to regrowth
  • Hair can grow thicker and longer
  • Clinicaly proven results
Cons
  • May cause irritation, rash or headaches

BosleyMD Healthy Hair Growth Supplements block DHT production with the help of the key ingredient pumpkin seed extract. The supplements also include hair growth helpers such as, biotin, niacin and zinc, We also appreciate that the supplements are cruelty-free and made without parabens, gluten or sulfates.

Product type: Shampoo | Key ingredient: Procapil | Best for: Thinning hair

BaumanMD is a line of hair care treatments formulated by board-certified hair restoration physician and hair transplant surgeon Dr. Alan Bauman. The fact that the line is founded by a physician with specialized expertise in hair loss deepens our trust in the brand. Dr. Bauman notes that the best treatments for hair loss are the ones that optimize scalp health and enhance hair follicle function. The BOOST Olfactory DHT-Control Densifying Shampoo does just that.

Procapil, which is a blend of oleanolic acid, apigenin, and biotinyl-GHK, is the star of the show for this product. This powerhouse active ingredient increases blood flow and nourishes your hair follicles, which only builds hair strength and thickness. Another key ingredient is Sandalore, which is a molecular compound that extends the hair growth phase of the follicle. At $49, it is a pricier option, but the fact it is formulated with a physician’s expertise leaves us confident it is worth the pretty penny. There's also a hair growth conditioner you can pair with the shampoo.

Pros
  • Hair loss physician founded
  • Increases blood flow
  • Enhances hair follicle function
Cons
  • Pricier option

Product type: Serum | Key ingredients: Curcumin stem cell extract, red clover, mung bean | Best for: Hair thinning and shedding

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.

Pros
  • Vegan
  • Blocks DHT
  • Decreases shedding
Cons
  • Expensive to maintain for three to six months

The Mane Choice’s Multi-Vitamin Scalp Nourishing Oil is a gentle and lightweight formula that boosts scalp health. By releasing clogged pores and build-up on the scalp, this reduces breakage and creates a healthy foundation for hair to grow.

While it is effective, it is also gentle enough to use daily. Apply it to your scalp once daily and massage gently before styling as usual. We also appreciate that the Mane Choice was founded by registered nurse Courtney Adeleye who used a science-based approach to develop multicultural hair solutions that prioritize scalp and hair health. It won’t break the bank, either – it is just $12.99 per bottle.

Pros
  • Helps unclog pores and clean buildup
  • Reduces breakage
  • Gentle for everyday use

  • Will need to pair with a second product to promote growth such as a minoxidil-based product

Product type: Laser cap | Best for: Thinning and growth from the hairline to the crown

Factors to consider when choosing hair growth products

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.

How we tested the best hair growth products

While researching 23 different hair loss companies, our team looked for innovative products that were science-backed, affordable, and effective. We paid special attention to products developed by hair care doctors or experts. We rated each product based on effectiveness, affordability, and ease of use. To make sure we were making selections that were medically-sound, we consulted with nine different hair loss experts.

Hair growth products FAQs

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.

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 are gender-specific. You also don’t want to assume that all products are pregnancy-safe. Be sure to do your due diligence in choosing a product and don’t forget to run it past your doctor to make sure it's safe for you.
