The 13 Best Hair Loss Treatments of 2022

Byrdie / Chloe Jeong

If you’re dealing with hair loss, take heart in knowing that you’re not alone. According to the Cleveland Clinic, more than 50 percent of women will experience noticeable hair loss at some point. Adding insult to injury, the cause of hair loss in women isn’t particularly clear-cut. It’s often multifactorial and can include things such as stress, hormonal changes, medications, genetics, and hair products that irritate the scalp, says dermatologist Dr. Peterson Pierre

Dr. Peterson Pierre is a board-certified dermatologist specializing in both medical and cosmetic dermatology.

If your hair loss is significant and bothersome, it’s always important to seek professional help, be it from your dermatologist or a trichologist. They can help determine the cause(s). And that’s important because, depending on the cause, you may need to use both a topical hair loss solution as well as take a hair loss supplement to truly treat your issue, says William Gaunitz, a certified trichologist (hair and scalp specialist) and founder of Advanced Trichology.

In terms of topical products, there’s no shortage out there, all claiming longer, stronger, fuller hair. But it’s super important to mention that there is only one FDA-approved medical treatment for hair loss in men and women: topical minoxidil, says Dr. Gaby Longsworth, Ph.D. , a certified hair practitioner and founder of Absolutely Everything Curly. “All other treatments and remedies have not been as extensively studied and are not FDA-approved,” she says.

That being said, there are still plenty of good options that can help. Here are the best hair loss treatments worth giving a try.

Best Overall: Rogaine Women's 5% Minoxidil Topical Aerosol Hair Regrowth Treatment

Rogaine Women’s 5% Minoxidil Topical Aerosol Hair Regrowth Treatment
What We Like
  • Easy to use

  • Dermatologist-recommended brand

  • Unscented

What We Don’t Like
  • Must use daily to maintain results

OTC minoxidil has a long-standing history of being effective in slowing down hair loss while promoting hair growth,” says Pierre. Longsworth is a fan, noting that this option, which contains a 5 percent concentration of the ingredient, is effective and scientifically proven to boost hair growth. In short, this is our top pick because there’s no question about it getting the job done. The unscented foam is easy-to-use, though FYI, it does have to be used daily to see and then maintain results. (But you get a two-month supply in one box, so this option isn’t too hard on your wallet.)

Type: Leave-on | Active Ingredients: Minoxidil | Dosage: Once daily | Cruelty-Free: No | Byrdie Clean: Yes

Best Overall, Runner-Up: Nioxin Hair Regrowth Treatment For Women

Nioxin Minoxidil Topical Solution USP 2% Hair Regrowth Treatment
What We Like
  • Gentle

  • Easy to use

  • Unscented

What We Don’t Like
  • Has to be used twice daily

  • Takes a little while to dry

Another minoxidil-based pick contains 2 percent of the active ingredient. Apply it (twice daily) just on top of the scalp, on any areas where you have hair loss. Reviewers rave about how well it works, though note that it does take some time to see results.

Type: Leave-on | Active Ingredients: Minoxidil | Dosage: Twice daily | Cruelty-Free: No | Byrdie Clean: Yes

Best Budget: Keranique Hair Regrowth Treatment for Women 2% Minoxidil Topical Solution USP

Keranique Hair Regrowth Treatment for Women 2% Minoxidil Topical Solution USP
What We Like
  • Targeted sprayer for precise application

  • Clinically proven

  • Affordable

What We Don’t Like
  • May leave hair greasy

A 30-day supply of this option, yet another pick that contains 2 percent minoxidil, comes in at just under 30 dollars, making it a great wallet-friendly choice. Plus, the targeted sprayer, an attribute that happy reviewers love, makes it super easy to apply exactly where you need it.

Type: Leave-on | Active Ingredients: Minoxidil | Dosage: Twice daily | Cruelty-Free: Yes | Byrdie Clean: Yes

Best Shampoo: Advanced Trichology HairStem DHT Blocking Treatment Shampoo

Advanced Trichology HairStem DHT Blocking Treatment Shampoo
What We Like
  • Targets various hair and scalp issues

  • Leaves hair soft

  • Trichologist-developed

What We Don’t Like
  • Three- to five-minute application

When a trichologist develops a hair loss product, you know it’s going to be good. While a rinse-off shampoo isn’t going to be a miracle solution on its own, it is a good option to use in tandem with other treatments. This one (the result of over 14 years of research) contains ingredients such as saw palmetto to help block DHT, an androgen that’s derived from testosterone and can shrink the hair follicle. Plus, it also contains natural antibacterial tea tree oil to combat scalp issues and strengthening biotin, among other ingredients.

Type: Shampoo | Active Ingredients: Saw palmetto, biotin, tea tree oil | Dosage: Up to three times daily | Cruelty-Free: Yes | Byrdie Clean: Yes

Best Conditioner: BosleyMD BosRevive Volumizing Conditioner

BosleyMD BosRevive Volumizing Conditioner

Ulta

What We Like
  • Doesn't weigh down hair

  • Comes in two sizes

  • Reduces scalp inflammation

What We Don’t Like
  • Not compatible with colored hair

By definition, a conditioner is meant for the lengths of your hair and not your scalp; in other words, it’s not going to do much in the way of growth. But what the right conditioner can do is help strengthen hair and make them look fuller, giving you instant gratification that other products can’t. This particular pick has panthenol to strengthen hair and improve moisture retention so that hair looks fuller, so much so that, according to a brand-backed study, 94 percent of users saw more volume in their hair.

Type: Shampoo | Active Ingredients: Panthenol | Dosage: Daily | Cruelty-Free: Yes | Byrdie Clean: No

Best Serum: Vegamour GRO Hair Serum

Vegamour GRO Hair Serum

Sephora

What We Like
  • Vegan

  • Non-greasy

  • Works on all hair types

What We Don’t Like
  • Dropper could be designed better

Vegan and cruelty-free, this relies on plant-based ingredients to help combat shedding and thinning. Namely, things such as turmeric and mung bean help address a variety of hair loss causes. Plus, it doesn’t have the issue that many other leave-on products have, namely leaving behind a residue and feeling greasy.

Type: Serum | Active Ingredients: Panthenol | Dosage: Daily | Cruelty-Free: Yes | Byrdie Clean: Yes

Best Supplement: Nutrafol Women Hair Growth Supplement

Nutrafol Women Hair Growth Supplement
What We Like
  • Has clinical evidence behind it

  • Targets various hair and scalp issues

  • Full of medical-grade, natural ingredients

What We Don’t Like
  • Pricey

  • Have to take four pills daily

According to Pierre, this is one of the very few supplements that has research backing up its claims. (And tons of devoted users back this up.) At work is a combo of ingredients, including saw palmetto, to help address DHT, ashwagandha, and marine collagen peptides, just to name a few. They (and others) work in tandem to help slow shedding and help hair grow longer, faster, and stronger.

Type: Supplement | Active Ingredients: Saw palmetto, ashwagandha, marine collagen peptides | Dosage: 4 capsules daily | Cruelty-Free: Yes | Byrdie Clean: Yes

Best Supplement, Runner-Up: Viviscal Hair Growth Supplements for Women

Viviscal Hair Growth Supplements for Women
What We Like
  • Gentle on the stomach

  • Drug-free formula

  • Nourishing

What We Don’t Like
  • Can take time to see results

A more affordable pick, Pierre says this has research behind it to show it works; credit a combo of biotin, iron, and horsetail extract. Not only can it help promote hair regrowth, but it also strengthens the hair you do have, always a good thing in our book. You only need to take two tablets daily, though bear in mind that it may take anywhere from three to six months to see results.

Type: Supplement | Active Ingredients: Biotin, iron, horsetail extract | Dosage: 2 capsules daily | Cruelty-Free: Yes | Byrdie Clean: Yes

Best Scalp Scrub: Drunk Elephant T.L.C. Happi Scalp Scrub

Drunk Elephant T.L.C. Happi Scalp Scrub

What We Like
  • Gentle

  • Squeeze-top applicator

  • Sulfate-free

What We Don’t Like
  • Hard to rinse off

Exfoliation isn’t just for your face or body. It’s also an important step for your scalp, where it can help eliminate built-up residue and dead cells that can clog the follicles from which new hair grows. We like this option because it uses a combo of different alpha-hydroxy acids—glycolic, citric, lactic, and tartaric—to dissolve all of the above without irritating. And unlike so many other scalp scrubs out there, it comes in an easy-to-use squeeze bottle versus a jar, which can easily get messy.

Type: Scrub | Active Ingredients: Alpha-hydroxy acids | Dosage: Once to twice per week | Cruelty-Free: Yes | Byrdie Clean: Yes

Best System: Collective Laboratories Regimen

Collective Laboratories Regimen

Collective Labratories

What We Like
  • Potent

  • Safe, daily regimen

  • Anti-bacterial

What We Don’t Like
  • Can take time to see results

This three-part system makes for a super easy (and very effective) way to address hair loss every single day. Suds up with the detoxifying shampoo, which contains DHT-blocking saw palmetto, then follow up with the strengthening conditioner. The final step is the brand’s hero product, a leave-on serum that stimulates microcirculation, strengthens hair, balances oil production, deters yeast growth, and can help address all kinds of different types of hair loss as a result.

Type: Shampoo, conditioner, serum | Active Ingredients: Varied | Dosage: Daily | Cruelty-Free: Yes | Byrdie Clean: Yes

Best for Scalp Health: Alodia Soothe Hair & Scalp Herbal Infusion

Alodia Soothe Hair & Scalp Herbal Infusion

Amazon

What We Like
  • Natural formula

  • Affordable

  • Feels great on scalp and hair

What We Don’t Like
  • Pricey

Healthy hair starts with a healthy scalp—it’s that simple. Enter this pick, one of Brown’s favorites. She lauds it for the use of jojoba oil: “It can penetrate the hair follicles and strengthen hair from the inside and also stimulates blood flow to the scalp to encourage healthy growth,” she explains. On top of that, it also contains tea tree, chamomile, peppermint oil, and spearmint oils, all of which cool, calm, and soothe an itchy or irritated scalp.

Type: Oil | Active Ingredients: Jojoba oil, chamomile, tea tree oil | Dosage: 1 to 2 drops per section of hair | Cruelty-Free: Yes | Byrdie Clean: Yes

Best Oil: Soultanicals Bloom-Supa Potent Healthy Hair Growth Oil

Soultanicals Bloom-Supa Potent Healthy Hair Growth Oil

Soultanicals

What We Like
  • Natural formula

  • Strengthens hair to prevent split ends

  • Stimulates blood circulation

What We Don’t Like
  • May leave hair greasy

Brown says she likes this pick because it contains rosemary oil, which can help stimulate hair follicle growth with daily application. She adds that it also improves blood circulation to the scalp and destroys bacteria that clog hair follicles, and has fewer side effects than minoxidil. Plus, there are other ingredients here that are good for your hair and scalp, including moisturizing olive oil, horsetail extract, and biotin, among others.

Type: Oil | Active Ingredients: Rosemary oil, horsetail extract, biotin | Dosage: 3 to 5 drops | Cruelty-Free: Yes | Byrdie Clean: Yes

Best Oil, Runner-Up: Tropic Isle Living Strong Roots Red Pimento Hair Growth Oil

Tropic Isle Living Strong Roots Red Pimento Hair Growth Oil

Amazon

What We Like
  • Restores hair's natural moisture

  • Volumizing

  • Can be used many different ways

What We Don’t Like
  • Feels a bit heavy to some

The start of the show here is castor oil, which is rich in ricinoleic, oleic, stearic, palmitic, linoleic, and linolenic acid, says Brown. These fatty acids have been shown to reduce DHT formation by inhibiting the enzyme that converts testosterone to DHT, she explains, adding that DHT production is a major cause of genetic hair loss. Also nice: There are plenty of ways to use it. It works well as a pre-shampoo treatment, hot oil treatment, or simply to accompany a scalp massage.

Type: Oil | Active Ingredients: Castor oil, coconut oil | Dosage: A liberal amount | Cruelty-Free: Yes | Byrdie Clean: Yes

Best for Shedding: Dr. Barbara Sturm Anti-Fall Scalp Serum

Dr. Barbara Sturm Anti-Fall Scalp Serum

Cult Beauty

What We Like
  • Trichologist-recommended

  • Protects against pollutants

  • Anti-itching effect

What We Don’t Like
  • Pricey

“When faced with the early signs of aggressive hair fiber shedding, managing hair loss concerns is essential,” says Bridgette Hill, a certified trichologist. This scalp serum is one of her top picks; the proprietary formulation with botanical active ingredients and nutrients helps keep the hair follicle healthy and the hair fiber strong and intact, she explains. Namely, extracts of camellia and larch. Also nice: It contains pro-vitamin B5 to keep the hair you do have from splitting.

Type: Serum | Active Ingredients: Purslane extract, sunflower seed sprout extract | Dosage: A few drops as needed | Cruelty-Free: Yes | Byrdie Clean: No

Best Preventative: Renee Furterer Triphasic Progressive Serum

Renee Furterer Triphasic Progressive Serum

Dermstore

What We Like
  • Easy to work into an existing routine

  • Nice smell

  • Drug-free formula

What We Don’t Like
  • May tingle the scalp to some

If you’re not dealing with hair loss quite yet, but want to get ahead of the game (and/or just keep your scalp and hair healthy), Hill recommends this serum. “It nourishes the scalp with hydration and feeds it the necessary ingredients to support scalp and hair at the cellular level, helping to create healthy hair,” she explains. It only needs to be used twice per week for the first month and once per week thereafter.

Type: Serum | Active Ingredients: Purslane extract, sunflower seed sprout extract | Dosage: Twice weekly for the first month and then once a week on an ongoing basis | Cruelty-Free: Yes | Byrdie Clean: No

Final Verdict

When it comes to hair loss treatments specifically, it’s best to temper your expectations. “Other than minoxidil, Nutrafol, and Viviscal, there are no other OTC products with any significant studies that show efficacy, so you should have low expectations if you decide to try such products,” says Pierre. Because they have research and reviews behind them, Rogaine Women’s 5 Percent Minoxidil Topical Aerosol Hair Regrowth Treatment, Nutrafol Women Hair Growth Supplement, and Viviscal Hair Growth Supplements for Women all score big thumbs up from Team Byrdie. You can also opt for products that help promote the overall health of your scalp, such as the Drunk Elephant T.L.C.Happi Scalp Scrub and Alodia Soothe Hair & Scalp Herbal Infusion, since creating a healthy scalp environment is essential for ensuring healthy hair growth.

What to Look for in a Hair Loss Treatment

Minoxidil

Trichologist Kerry Yates of Colour Collective stresses that there is a multitude of reasons why you could be experiencing hair loss (more on that below) and that there is no single cure. However, she says there are many products out there that support both scalp and hair health, so it's important to get to the root of your issue and treat it accordingly.

She says there is truly only one ingredient approved by the FDA to help regrow hair: minoxidil. “It was initially created to support patients with hypertension and later found to help regrow hair,” she says. “It’s reported to push the hair from the resting phase to the growing stage. However, there is no defined reason for how this happens.” She also mentions that there may be some adverse side effects when using a Minoxidil product, so be sure to do your research before trying it for yourself. Of course, there are plenty of products on the market that can improve hair health, though they don’t boast growth benefits.

Scalp Health-Boosting Ingredients

A healthy scalp is the key to healthy hair, so Yates also suggests reaching for products, such as ingestibles, that contain scalp health-boosting ingredients. If you’re dealing with an itchy scalp, dandruff, or irritation, she recommends topical ingredients like salicylic acid or natural options like rosemary, peppermint, and tea tree oils.

With that in mind, she also recommends avoiding products with silicones and heavy oils. “Silicones or heavy oils of any type combined with your hair’s natural sebum can clog the follicles, causing follicle stress and negatively impacting overall follicle fitness," she says.

DHT-Blocking Ingredients

Yates says it could be beneficial to try a DHT-blocking product if your hair loss is related to hormones or genetics. “Fluctuations in hormones can negatively impact your hair’s life cycle,” she says. “For example, dihydrotestosterone (DHT), derived from testosterone, can shrink the follicle, basically ‘killing’ it and causing hair loss and future hair growth challenges. It’s thought that topically applied DHT blockers like saw palmetto and pumpkin seed oil could help eliminate DHT from attacking the follicle.”

FAQ
  • What are the causes of hair loss?

    Gaunitz explains that genetic hair loss in both men and women is connected to a sensitivity to DHT and revolves around certain levels of androgens connected to hair follicle receptors. “This type of hair loss only affects the top of the scalp,” he says.

    Gaunitz adds that inflammatory hair loss—the kind caused by stress, medications, and lifestyle factors—is the most challenging to deal with because everyone is different. “This type of hair loss can be patchy and unpredictable and be associated with itching and burning,” he says.

    Another big cause of hair loss? Lack of nutrition. “Nutritional hair loss, in my opinion, is the most prominent form of hair loss worldwide and is also the most easily correctable,” he says. “Nutritional hair loss causes general thinning throughout the entire scalp and can exacerbate other types of hair loss.” 

    To get your hair back to its thickest, fullest potential, it’s important to address all the root causes of your hair loss. “Hair is very sensitive to inflammation, so it's important to avoid anything that irritates the scalp, such as certain hair dyes,” says Pierre. “The frequent use of heating tools can cause breakage. You should also condition your hair and moisturize your scalp regularly to minimize your chances of hair loss.” 

    As for nutrition, you want your doctor to run a full blood panel, so they can recommend nutrients you could be lacking. For healthy hair, key nutrients are iron, zinc, ferritin, folate, and vitamin D3, says Gaunitz.
