Hair thinning and hair loss can be frustrating and emotional experiences, whether caused by genetics, hormones, stress, or aging. While no shampoo can completely reverse hair loss, the right formula can make a significant difference by improving scalp health, reducing breakage, and creating the appearance of thicker, fuller strands. From DHT-blocking ingredients to nourishing vitamins and antifungal agents, some shampoos stand out for their ability to support healthier hair growth and minimize shedding.
Below, we checked in with several hair care experts to explore the best options when it comes to growing your locks with the help of shampoos. Read on to learn more!

1. Avalon Organics Thickening Biotin B-Complex
When you have thinning hair and want to encourage hair growth, it's all about finding shampoos that are gentle and nourish, says Casey Simmons, owner of Royal Locks Curl Care. And Allison Gandolfo, who is a designer colorist at Zahir Ziani Salon, went into more detail about some of the ingredients we should be looking out for when purchasing a shampoo for thinner hair.
Some of those are: essential oils, jojoba oil, peppermint, seaweed collagen, aloe vera, shea butter, and biotin. "The ingredients you want to stay away from are: sulfates, triclosan, polyethylene glycols, mineral oil, benzene, parabens, short chain alcohol, formaldehyde, dimethicone, diethanolamine, and artificial dyes," Gandolfo added. The Avalon Organics Thickening Biotin B-Complex shampoo boasts a powerful combination of biotin, saw palmetto, quinoa protein, and vitamin E.
2. Oribe Serene Scalp Anti-Dandruff Shampoo
Hair specialists advise opting for sulfate-free shampoos, ideally with a pH of 6 to 7 for straight hair and 4.5 to 5.5 for curly hair. When seeking hair care products that repair, fortify, and hydrate, prioritize ingredients like biotin (Vitamin B7) for promoting follicle growth and Panthenol (Vitamin B5) for reinforcing hair strength.
"Hair products with proteins (wheat and soy amino acids) coat the hair shaft acting as bonds to the molecules, promoting the look and feel of thicker hair. A diet or supplements that includes these amino acids can likely add to further hair growth," Simmons said, before telling us why the Oribe shampoo ($52 via the brand's site) gets her vote.
"Oribe is the king of styling products [and] makes a scalp shampoo that helps cleanse the scalp and promote hair growth," Simmons shared. "This sulfate-free shampoo keeps flakiness at bay while supporting optimal moisture balance of the scalp and hair. Salicylic acid gently exfoliates, while bilberry fruit and sugar maple extracts simultaneously soothe the scalp. Salicylic acid has proven to be adept at clearing dead skin cells and other pore-clogging impurities."
3. R+Co Atlantis Moisturizing B5 Shampoo
Celebrity hairstylist Michael Canale revealed to us that one of the best shampoo options to fight thinning hair is those that contain B-5. Vitamin B-5 (aka pantothenic acid) is a water-soluble B vitamin renowned for its ability to thicken hair and prevent hair loss. Furthermore, it offers excellent moisturizing benefits. According to Canale, Vitamin B-5 is a staple ingredient in hair-thickening shampoos—and for good reason.
When used regularly, it can help to strengthen hair follicles and works to thicken each individual strand, promoting healthier, fuller hair. "This ingredient swells the hair shaft, plumping each strand of hair to give it a thicker and more voluminous appearance," Canale explains. And this Vitamin B5: R+Co Atlantis Moisturizing B5 Shampoo ($34 via Amazon) is a great option!
4. Shapiro MD DHT Fighting Shampoo
Hair thinning can feel frustrating, but the right shampoo may help you regain a sense of control. Shapiro MD’s DHT Fighting Shampoo is specifically formulated to address one of the root causes of hair loss: DHT, a hormone linked to follicle shrinkage and thinning strands.
This dermatologist-developed formula features powerful ingredients like saw palmetto and EGCG (a green tea-derived antioxidant) to help combat DHT’s effects. It also includes nourishing oils—such as argan, avocado, chia seed, and pumpkin seed—to hydrate the scalp and support a healthier-looking, fuller head of hair over time.
5. Odele Volumizing Shampoo For Lift + Fullness
If you’re dealing with thinning or flat hair, one of the biggest mistakes you can make is over-cleansing your scalp. According to hair experts like Simmons, shampoos that contain sulfates may leave hair feeling “squeaky clean,” but they also strip away the natural oils your hair needs for softness, shine, and volume.
“Sulfates can over-wash hair by stripping away the natural oils it needs to have movement and shine without frizz,” Simmons explains. That’s where Odele’s Volumizing Shampoo comes in—this sulfate-free formula is designed to gently cleanse while preserving your hair’s moisture barrier. It boosts body and fullness without drying you out, making it a smart choice for anyone looking to maintain volume and scalp health.
Simmons warns that super-clean hair can be "counterproductive," leading to extra oil production in the long run. This is because when you strip your hair of all of its vital oils, your body will work extra hard to replenish them, which can end in a greasy mess and weigh your hair down. This will result in flat, lifeless hair that needs a serious volume boost. Additionally, some sensitive scalps can be irritated by this cleansing ingredient; and an irritated scalp is one major culprit of hair loss.
That's why a sulfate-free shampoo such as the Odele Volumizing Shampoo for Lift + Fullness is the best option if you want to avoid thinning hair and keep your locks as thick and healthy as possible. "Choose a shampoo without sulfates to avoid stripping natural oils your hair needs," Simmons suggests.
6. Nizoral Anti Dandruff Shampoo
When tackling thinning hair, treating scalp health is just as important as targeting the hair itself. Dermatologist Dr. Leela Athalye of Island Dermatology highlights Nizoral Anti-Dandruff Shampoo as a top pick—not just for dandruff, but also for its potential to support hair growth.
“Dandruff can be associated with hair loss, so by decreasing the dandruff, hair can grow better,” Dr. Athalye explains. Nizoral’s active ingredient, ketoconazole, helps reduce the yeast on the scalp that causes flaking and irritation, creating a healthier environment for hair to thrive. For those with scalp issues contributing to shedding or stunted growth, this shampoo is a powerful multitasker.
