Hair loss is frustrating, but we don't have to tell you that. According to the American Academy of Dermatology Association, hair loss affects an estimated 80 million Americans. And the effects aren't just aesthetic — research studies have shown that it can have psychological impacts, too.
We know how difficult losing hair (and addressing it) can be. That's exactly why we've spent a lot of time through the years speaking to top experts in the field to learn more about the ingredients and solutions that actually work to help promote hair growth.
There are copious products available on the market for hair loss but here, we're sharing a handful of those — along with some of the expert-recommended and top-rated products that shoppers and our editors swear by.
Minoxidil for hair loss
When it comes to regrowing hair at home, Minoxidil (the generic form of Rogaine) is one of the most popular solutions. It comes up in almost every conversation we have with experts about hair growth — and for good reason. When used consistently, the treatment has been clinically proven to boost hair growth. As with all products we mention, it's best to speak with your personal provider first to make sure the topical ingredient is safe for you to use.
Hers Minoxidil Topical Hair Regrowth Solution
- Drops allow targeted treatment
- Formulated for women
- 1-month supply
Size: 2 oz. | Key ingredients: Minoxidil
For anyone who may be wary of trying Minoxidil, this solution has a lower concentration of the ingredient, at 2%. The bottle is said to have enough product for about one month of use, though the brand says you likely won't see results for around three to six months.
“The 2% minoxidil in this solution actively promotes hair growth by shedding old hairs and replacing them with new, stronger ones,” says Maria Elizabeth, a hairstylist and the founder and owner of Salon DeZEN.
Amazon Basic Care Minoxidil Topical Solution
- Contains 2% minoxidil
- Unscented
- Should be used 2x per day
Size: 6 oz. | Key ingredients: Minoxidil
Amazon's Minoxidil formula is an affordable solution with more than 3,500 five-star ratings. It contains 2% Minoxidil and comes with a three-month supply of product.
"This stuff works and without it I don’t think I would have any hair," shares one verified shopper. "It does take a bit for it to start working, so don’t give up. Use this whole box, twice a day like it says and when you get the end of your last bottle you will notice a difference!"
Women’s Rogaine 5% Minoxidil Foam
- Unscented
- Foam, so it doesn't run
- Have to use it consistently
Size: 2.11 oz. | Key ingredients: Minoxidil
“It’s a tried-and-true solution to help combat hair loss,” Dr. Orit Markowitz, a leading dermatologist and the CEO and founder of OptiSkin, previously shared with Shop TODAY. “The foam penetrates your scalp and targets your hair follicle to reactivate the growth cycle.”
One thing to note: If you notice you’re losing more strands than usual after you first start using the product, that can be a common side effect, so don’t give up on it. “For people who are already shedding, it can be a little alarming,” shares Dr. Robert Finney, a board-certified dermatologist based in New York City. “So I always counsel that it’s normal, it’s just kicking your hair that was about to go into the resting phase out. It’s going to regrow, and it’s going to regrow healthier.”
BosleyMD Minoxidil Spray
- Easy to use
- Dries quickly
- Can make hair "crispy"
Size: 2 oz., 2 count | Key ingredient(s): Minoxdil 2%
Commerce editor Vivien Moon said she had used this product for a few months and saw baby hair growth, however, she notes that it can make your hair flaky more quickly.
“I didn’t feel any side effects or had anything concerning happen so I would recommend it to others looking for a solution. It’s easy to apply and I especially loved that it only took a minute to apply it once a day (that’s what I was doing at least)," says Moon.
Rosemary oil for hair loss
In recent years, rosemary oil has gained a loyal following across the internet, and many people swear by it as a natural hair growth solution. And according to Dr. Michelle Henry, a board-certified dermatologist in New York City, the evidence shows that it may actually be an effective tool.
“Rosemary oil is equivalent to 2.5% minoxidil, which is pretty impressive,” she previously told us.
Even better, it tends to be well-tolerated with minimal side effects so most people can incorporate it into their routine. "It’s something that we can use during pregnancy or for patients who just don’t want to use minoxidil or are intolerant to it,” Henry said.

Mielle Organics’ Strengthening oil is a bestseller with more than 70,000 perfect five-star ratings on Amazon. Not only does it contain rosemary oil (it’s the third ingredient on the ingredient list), but it also has nourishing ingredients like biotin, coconut oil and tea tree oil.
“I’ve been experiencing hair loss since I entered high school,” shares one Amazon shopper. “I went to doctors and got [prescribed] things that were supposed to help. However, nothing has worked as well as this oil (not to mention this is significantly cheaper than anything the doctor prescribed). I noticed results within a month and now several months later, my hair is looking more and more like it used to!”
Maple Holistics Pure Rosemary Essential Oil
- Multiple uses
- Many sizes available
- Some complain about the smell
Size: 1 oz. | Key ingredients: Rosemary oil
Henry shared that one way to try using the ingredient is to combine a pure oil, like this one, with a carrier oil (such as grapeseed or coconut oil), to help your skin better tolerate the ingredient. Apply the treatment to your scalp twice per day for best results.

Nuele Hair Serum
- Has a pleasant scent
- Feels gentle
- Applicator not included
Size: 2 oz. | Key ingredients: Rosemary
"I started using again this hair serum as a scalp moisturizer," says writer Jannely Espinal. "While the serum is intended for use after washing your hair, I use it as a heat protectant, before I straighten it. It protects my strands and doesn’t leave a greasy texture. Plus, it’s formulated with natural oil ingredients like argan, rosemary, jojoba, clary sage and moringa. I just use a few drops around my hairline and crown where I started seeing hair thinning."
Redensyl for hair loss
During an appearance on TODAY, Henry shared that the ingredient Redensyl has been shown to have results "similar to Minoxidil, without the irritation, without the excess hair growth."
The Ordinary Multi-Peptide Serum
- "Extremely lightweight"
- For all hair types + textures
- Should be applied at night
Size: 2 oz. | Key ingredients: Redensyl, Procapil, Baicapil
This serum from The Ordinary is designed to help your hair look visibly thicker and fuller. After using this product for a couple of months, associate editor Shannon Garlin said that she "noticed vast improvements to my scalp and hair."
"And while bad habits have been hard to break (I gave my mane a box-dye last summer), I still feel like the consistent use of this serum has started to repair my many years of hair abuse. My hairline looks fuller and there’s new growth starting to appear. I even have family and friends commenting on how long my locks have gotten."
The formula features Redensyl as well as Procapil and Baicapil, which the brand says work together to target stem cells, increase blood circulation and increase hair density.
Kintsugi Awakening Mist
- Suitable for all hair types
- "Ultra-lightweight"
- Use twice per day
Size: 4 oz. | Key ingredients: Redensyl, niacinamide, keratin
Along with supporting hair growth, the brand says that this mist is designed to minimize buildup, add volume and hydrate your strands. For best results, the brand suggests using it twice per day.
"It’s really unbelievable how much better my hair looks and feels," one verified shopper on the Kintsugi site said. "Friends, co-workers, and even my hairdresser have asked what I’m doing. And now they are using the Kintsugi products! I couldn’t be happier with my 'new' hair!"
Caffeine for hair loss
Sure, your morning cup of coffee is essential to your routine, but did you know that caffeine can also have benefits for both your skin and hair, too? While its connections to hair growth are still being explored, experts say it may have beneficial effects.
“Caffeine is a stimulant that increases circulation, allowing beneficial nutrients and oxygen to be delivered to the hair follicles to keep them healthy,” Dr. Michele Green, a board-certified dermatologist in New York City, previously shared with us. Research has shown that caffeine can help block the conversion of testosterone to dihydrotestosterone, a hormone that has been linked to hair follicle damage, which can lead to androgenetic alopecia (aka male- or female-pattern hair loss), she added.
While other hair loss treatments, like Minoxidil and Finasteride (a prescription treatment), have shown to be more effective, Dr. Chesahna Kindred, a board-certified dermatologist in Maryland, says that studies show that the ingredient may be helpful for people who suffer from androgenetic alopecia and stress-induced hair loss.
Alpecin C1 Caffeine Shampoo
- Cleanses scalp
- Nourishing castor oil

"I saw significant improvements in shedding after less than a week of usage," one shopper shared. "I’ve used it for over 6 months now and it leaves your hair softer and stronger and with so much less breakage and shedding."
Pura D’Or Scalp Therapy Energizing Scalp Serum

- Some struggle with pump
Size: 4 oz. | Key ingredients: Caffeine, niacin, argan oil
This formula from shopper-loved brand Pura D’Or blends argan oil, caffeine, biotin, niacin and more to help reduce hair thinning and increase the volume of your hair, the brand says. For best results, apply daily to damp or dry hair.
“Oh my god! After a month I noticed decreased shedding in [the] sink and shower,” one Amazon shopper wrote. “After two months my hairdresser said I had tons of new hair growing. Now at three months my hair is thick and beautiful and very strong!”

Green shared that The Inkey List’s caffeine treatment is another example of a product that contains the ingredient. The affordable formula features both caffeine and Redensyl. The brand suggests applying it all over your scalp every night for best results — according to the brand, you'll likely see a difference in your hair in as little as three months.
"For the price point this stuff is fantastic!" one shopper on the brand's site shared. "As a mid-life woman my hair has started to thin and shed and growth has slowed down. I am on my third bottle of this and it really does stimulate hair growth. I use it each evening along with the Inkey scalp massaging brush and wash my hair the following day (as I’ve got generally oily and fine hair)."

"I have been losing hair like crazy. I’m talking hair on my pillow when I wake up, even just gentle touching my hair would cause hair loss and every time I would wash my hair I would lose 124 hairs in the shower," one shopper wrote. "This went on for over 4 months. About 4 weeks ago my stylist told me to try this product. I noticed a huge change in hair loss about 2 weeks in. Im back to normal shedding (like 5-10 hairs lost when washing my hair). This has really helped reduce the amount of hair loss that I was having. I love the minty smell and tingle that the conditioner leaves on my scalp. Also, the shampoo lathers very nicely."
