The 34 Best Hair Growth Shampoos, According to Stylists and Derms

Okay, yes, technically this is a shampoo and conditioner bundle, but the more the merrier! This set uses biotin to stimulate hair growth and thicken hair, while collagen protects your hair from aging, fraying, and free radicals.

This drugstore favorite's active ingredient, caffeine, is designed to invigorate hair growth. This phthalate-free formula also removes dead skin buildup on your scalp to maximize growing potential.

Not only does this shampoo support scalp balance and soothe skin irritation that can impede hair growth, but it also detangles hair in order to prevent breakage once you're out of the shower.

We love an ethical, sustainable shampoo option! This coconut-scented bar shampoo promises to maximize scalp health while deeply conditioning hair―and all without that wasteful plastic packaging!

I love this shampoo. Its tea tree oil, chamomile, and eucalyptus are sure to heal your scalp (and make it tingle a bit) and make your hair glow so that you're left with a long, healthy, clean mane.

This option, which comes highly recommended for textured hair, repairs color- and heat-damaged strands while supporting follicular health.

This shampoo/conditioner duo supports scalp health, incorporating aloe vera in order to soothe tired, damaged scalps.

This coconut cowash is an excellent option for folks with curly or textured hair. Not only does it remove residue from hair products, grease, and pollution, but it also supports scalp and follicular health so that your locks grow strong and long.

Celebrity stylist Takisha Sturdivant-Drew swears by this inexpensive option, which results in hair that looks super-thick and full. "The biotin and collagen pump up the volume on fine hair and leaves all textures with a beautiful shine," she says. "Most of all, its ingredients bring brittle hair back to life with new growth." Dermatologist Rachel Nazarian, M.D., also recommends this shampoo to her clients. "In terms of anti-inflammatory and strengthening shampoos, I recommend OGX, which is sulfate-free and less drying than many shampoos. The keratin proteins and argan oil strengthen the cuticle for stronger hair." Which means less breakage.

Bosley is known for their hair growth remedies and yes, the Bosley Hair Transplant, so it’s no surprise that their shampoo is a favorite amongst experts and users for hair growth. Certified trichologist Gretchen Friese says, “The Bosley shampoos and conditioners are formulated with biotin, niacin, and panthenol to help nourish and strengthen hair and encourage growth. It protects against thinning by removing build-up from the scalp surface, while cleansing hair of product build-up and pollution.”

It's impossible to talk about hair growth without bringing up this crowd favorite. If you have fine, thin hair, this shampoo is your best bet. "A classic standby and the OG shampoo for hair growth is Nioxin’s Shampoo," Kendall Dorsey, stylist to the stars (think: Teyana Taylor, Cardi B., Bella Hadid), confirms. "When you use it, you’ll feel a refreshing tingle, letting you know it’s working. It’s packed with vitamins, botanicals, SPF, and amino acids to help protect hair and promote healthy new growth." Stylist Michael Dueñas agrees. "Nioxin is fantastic for slowing temporary hair loss due to stress, environmental factors, and certain health issues," he says. Just in case you needed another expert's stamp of approval, stylist Kat Thompson also backs Nioxin, pointing out that customers can select a shampoo system based on the severity of their hair loss: "I’ve had many clients say they’ve noticed quick results when using it."

Taylor suggests incorporating this shampoo into your wash routine because it strengthens and restores the hair with the one-star ingredient. "Jamaican Black Castor Oil increases blood flow to the scalp, supplying nutrients to hair follicles, which speeds up hair growth," Taylor confirms.

Celebrity hairstylist and Virtue Labs creative director Adir Abergel cautions against using hot tools if your goal is growth. If your thinning hair is preventing growth, he recommends this clinically tested and nourishing shampoo. “A healthy scalp is the start point for hair growth. Virtue Flourish is a brand new approach to address female hair loss that creates a more fertile ground for hair to grow by restoring the scalp, clearing the follicles, and improving microcirculation,” says Abergel. The ingredients also speak for themselves with peptides that help nourish the scalp and rice-based humectants that give hair a sleek finish without any of the weight of silicones. Also, it might seem counterproductive, but trimming your hair will actually help the growth process, Abergel explains, “If you wait too long between trims, your split ends will work themselves up and more breakage will occur.”

For blondes out there, celebrity stylist Christine Symonds recommends the iconic Shimmer Lights Purple Shampoo from Clairol. You might be tempted to re-bleach brassy hair, but this shampoo helps with brassiness and avoids the damage of more bleach treatments. “The key factor in growing your hair out is refraining from causing any damaging factors." There are so many things you can do to prevent damage. Weekly masks and refreshing your color without invasive methods are a great start. This shampoo "is a great way to refresh and maintain your color without having to add more bleach and damage,” says Symonds.

Another recommendation from Friese: The salon-favorite lengthening shampoo from Redken. “It is PH balanced and provides biotin for “length fortifying protection,” says Friese. Ideal for damaged hair, this shampoo is the first step in a routine that will strengthen and moisturize hair, while also cleaning it at the root.

Giovanni Vaccaro, celebrity hairstylist and artistic director of Glamsquad, believes that when it comes to repairing hair, it's essential to find a shampoo and conditioner that can penetrate the hair follicle, impart strength, and add moisture. "Recently, I've been loving Kérastase Resistance Length Strengthening Shampoo and Conditioner. It's built with creatine and taurine, an amino acid that protects the hair fiber and scalp. In turn, your hair will definitely feel stronger and healthier." If you're looking for even more moisture, try the Resistance Length Strengthening Mask ($59).

Dorsey says this is the very best shampoo for hair growth. Here's why: "It's specially formulated with a blend of actives and antioxidants such as baobab, rosa multiflora, and swertia chirata to block the production of FGF5, a protein that causes hair loss," he explains. "This line was developed by hair biologists and is backed by clinical results—I’ve seen the results for myself on clients, but it's nice to have science to prove it."

"This is a fabulous option for those with scalp damage," says Engelman. "The shampoo combines keratin, bamboo plant stem cells, argan oil, and prickly pear oil. And together, they protect from environmental damage, extend the anagen [active growth] phase of the cycle and condition, reducing frizz and fortifying healthy strands."

If you're in the market for a hair growth shampoo, chances are you wouldn't mind fuller-looking hair while you wait for new follicles to sprout. Here, rice bran and amino acids work immediately to expand the diameter of the hair shaft while ginger root and nettle extract invigorate the scalp to maximize new growth.

Cortney Crace, a stylist at New York-based Salon Suite Caroline, can testify to the magic of Davines' Naturaltech line. "The shampoo energizes with balancing properties in it that promotes hair circulation of the scalp," she explains. "Keeping it all in the same line for best results, use the conditioner ($37) on the mid-ends of your hair shaft, so the scalp does not get weighed down."

Master trichologist and colorist Bridgette Hill knows the ins and outs of all things scalp health and wants to stress the importance of keeping a well-balanced hair care regimen and balanced lifestyle. "A single product [like shampoo] plays a small part in an overall regimen for combatting hair loss and thinning," says Hill. She praises CR Lab's Hair Loss Prevention Shampoo for its nourishing and strengthening properties. "It's designed to support the extension of the anagen [active growth] phase of the hair cycle. Essential oils also work to soothe and purify the scalp," she explains.

Hill suggests this strengthening shampoo to clients struggling with thinning hair; it instantly helps create a thick and luscious appearance. "This shampoo fortifies proteins at the base of the hair fiber to give the illusion of thicker, denser hair," she explains. "It also has active ingredients to support cellular turnover and is enriched with anti-inflammatory oils such as orange, rosemary, and lavender."

Dermatologist Dendy Engelman recommends opting for a cleanser that works to simultaneously deliver nutrients while detoxing the scalp and follicle of harmful buildup. "This one isn’t technically a shampoo but can be used as a replacement for those that wash too often. I do it myself once a week, to mitigate flakes, balance pH levels and soften the scalp," says Engelman. "While removing oil from your skin, apple cider vinegar also helps to balance pH and keep your scalp and hair from becoming too oily or dry by balancing the production of sebum." The anti-inflammatory and acetic properties also help hairs grow out more easily, she explains.

Celebrity hairstylist Lacy Redway, whose clients include Tessa Thompson and Zazie Beetz, recommends this purifying shampoo as a cost-friendly lifeline for dull and limp strands. "It revives your scalp and allows for a clear passageway for your hair to flourish," she explains.

"I hadn’t tried cold-pressed shampoo until this one, which gently cleanses and refreshes your hair. It also helps balance the pH levels in your hair and leaves it feeling shiny and healthy," recommends Redway.

"Mielle Organics Pomegranate Honey Shampoo purifies your hair without stripping it of its natural oils," says Redway. "This one is great for my girls in the type-four hair range. I also like to supplement Mielle Organics Healthy Hair Vitamin with Biotin in addition to the other vitamins I take daily. The biotin leads to healthy hair, nails, and skin."fBest for Textured Hair

Celebrity stylist Andrew Fitzsimons, who counts the Kardashian-Jenner sisters as his clients, is partial to this do-it-all shampoo. "There are two factors to consider when it comes to hair growth: the health of your scalp and the health of your strands themselves," he explains. "People with damaged hair tend to see more breakage, which translates to slower hair growth. This is my favorite shampoo to use for color-treated, chemically-processed, heat-damaged, or sun-exposed hair."

Dry hair = dull hair = unhealthy hair. The more moisture, the better for the long locks of your dreams. "This shampoo contains honey, which is a rich antioxidant that can prevent damage and keep your scalp healthy," says Taylor. "Additionally, honey is great to seal moisture into your hair, keeping it conditioned and preventing breakage, which slows hair growth."

Celebrity stylist Nikki Nelms, who works with Zoë Kravitz, Janelle Monae, Yara Shahidi, and more, is a fan of this drugstore gem for a good reason. Nelms is also a huge proponent of a healthy, hydrated scalp for optimal hair growth. "Use a shampoo like Maui Moisture's Detoxifying + Volcanic Ash Shampoo because it has essential ingredients like ginger extract and aloe, which refresh the scalp and add hydration so that your hair will grow to its healthiest potential. It’s also important to be gentle with your hair throughout this journey and use tools like Goody Total Texture detangling paddle brush infused with mongongo oil to prevent excessive shedding.

This all-natural all-star uses apple stem cells to promote hair growth and delay aged hair follicles. According to Crace, this is the best way to apply the serum for optimal results: "This is a restorative serum powered by active ingredients, like apple stem cells and hydrolyzed protein from the plant sweet white lupine. Part your hair in sections, pinch the dropper, and apply the product through your entire head, focusing on the scalp. Then, run your fingers through your scalp to shake it all in and spread the serum, keeping it at the scalp as a leave-in treatment. You can use this daily or as often as you shampoo. The best hair growth results happen in three to six months.”

"I am also a big fan of Briogeo's Don't Despair, Repair line," Giovanni adds. "It's cruelty-free, and 95 percent of the formula is naturally derived. The shampoo and conditioner have algae extract and biotin, which promote hair strength and elasticity. It also has a lovely feel that won't weigh your hair down."

Ashley Streicher, a celebrity hairstylist for Garnier Brand Ambassador Mandy Moore, is a fan of this drugstore gem. "This shampoo and conditioner fortify hair with a powerful dose of active fruit concentrate and ceramides," Streicher says. "The formula goes deep to fortify each strand from core to cuticle and reinforces hair’s natural substance from root to tip. Plus, Fructis packaging contains 50% Post-Consumer Recycled Waste."

When you hear "Rogaine," you might think "for men," but Dueñas says it's a huge help in creating a thicker and fuller hairline for women—and can stop hair loss and baldness. Dr. Engelman is also a fan of Rogaine and Ketoconazole, another over the counter option. In a study, researchers discovered that 2 percent of Ketoconazole shampoo increased the size and proportion of anagen hair follicles (hair that's in its growth phase).

Tea tree, the star ingredient in this shampoo, is an ideal buildup buster. "Tea tree oil helps to clear the blockages in the pores, and helps to prevent dryness and itching," Dr. Engelman explains.
