Byrdie / Jessica Juliao
Healthy hair is an understandable goal—after all, it's a large part of your daily look. If you're struggling with hair loss, however, you're not alone. According to UK-based trichologist Kate Holden, AIT, "Hair loss is incredibly common among women." Whether you're dealing with stress-induced shedding, postpartum thinning, hormonal hair loss, or hair that doesn't seem to want to grow, there might be hope in an over-the-counter treatment—shampoo.
Byrdie Researched & Approved
Our top choice, the Kérastase Densifique Bain Densité Shampoo, helps to fortify, plump, and protect fragile hair. If you need something more budget-friendly, try the Marc Anthony Grow Long Super Fast Strength Shampoo, which includes ginseng and caffeine to help stimulate the scalp.
"Shampoos can help with hair growth by strengthening the hair shaft, reducing breakage, and cleaning the scalp," Holden tells Byrdie, noting that maintaining a healthy scalp is crucial.
To prevent breakage, Holden recommends formulas infused with protein, such as hydrolyzed keratin and wheat protein, along with conditioning ingredients like glycerin and coconut oil. "In terms of cleaning the scalp from buildup," she says, "ingredients such as salicylic acid, glycolic acid, and lactic acid can be beneficial, as they are chemical exfoliants that remove dead skin cells."
We conducted extensive research, consulted with experts, and tested top-rated and best-selling products to find the best strengthening, breakage-fighting, and scalp-supporting shampoos that help boost hair growth. We evaluated each formula's ingredient list and ability to strengthen, thicken, and reduce damage, and then we narrowed the field down to our picks.
Here are the best hair-growth shampoos recommended by experts.

What to Look For in a Hair Growth Shampoo
Scalp Support
When it comes to growth-boosting shampoos, board-certified dermatologist Dr. Dendy Engelman recommends looking for a product that supports overall health of your scalp in addition to your hair cuticle and hair follicle. “The scalp plays an important role in growing and maintaining strong, healthy hair,” she says. Therefore, you want to make sure it’s being properly nourished and treated for optimal hair health and growth.
Stimulating Ingredients
Dr. Engelman also stresses the importance of using a formula that contains stimulating ingredients, such as biotin, zinc, niacin, peppermint, and caffeine. “These stimulate blood flow to the scalp and nutrient delivery to the hair follicle, promoting hair growth,” she says. That said, the more of these ingredients a product contains, the better. We like the Nanogen 7-in-1 Thickening Hair Shampoo, which gently exfoliates the scalp to rebalance its natural microbiome and also Oribe's Serene Scalp Anti-Dandruff Shampoo, which tackles flakes with salicylic acid and strengthens with keratin. The Redken Extreme Length formula contains a high concentration of biotin to promote healthy growth.
Conditioning and Moisturizing Ingredients
Hair that’s dry and stripped of its natural oils won’t lead to healthy growth, so Dr. Engelman recommends looking for products—like the Davines Naturaltech Nourishing Shampoo—that also contain conditioning and moisturizing ingredients. “These are key because they keep the strands healthy and strong.” We love the SheaMoisture Restore & Grow formula because it contains a blend of humectants, including raw, organic shea butter as well as clarifying oils to deliver conditioning and moisturizing benefits.
Dr. Engelman recommends people steer clear of shampoos that contain sulfates, which can dry out (and irritate) your scalp.
