The 20 Best Hair-Thickening Shampoos For Blowout-Level Volume
We do a lot to keep our hair looking full and healthy—after all, no woman wants flat, lifeless locks. Whether you have naturally fine hair that’s in need of a boost, or you noticed your part is visibly thinning (which could be a sign of hair loss), the best hair-thickening shampoos are a solid place to start.
“There aren’t any shampoos that have been clinically proven to regrow hair,” says Gretchen Friese, certified trichologist and director of Foushee SalonSpa. “However, a hair-thickening shampoo can encourage hair growth by creating a healthy scalp environment and increasing circulation to the hair follicles. Products that fight DHT—the hormone that causes the most common kind of hair loss, androgenetic alopecia (AGA)—can also help keep the hair in the growing phase longer, which encourages thicker locks,” she adds.

Dermatologist Dr. Kseniya Kobets notes that natural ingredients like green tea may inhibit DHT. “Although there are limited studies in humans, a recent review found that additional ingredients such as caffeine, melatonin, rosemary oil, pumpkin seed oil, and saw palmetto were effective in treating male AGA and thus could possibly help with female AGA, too,” she says.
Another way thickening shampoos work is by increasing the diameter of each hair strand, helping to make the hair look and feel thicker, Friese explains. “Some of the technology used delivers nutrients into the cortex of the hair to create girth in the hair strand,” she says. “Meanwhile, other products sit atop the hair shaft to create a temporary thickening effect.” While these won’t permanently change the anatomy and density of your hair, remember that consistency is crucial as with any hair growth serum or growth oil. “There aren’t any quick fixes or forever changes, but regular use of thickening shampoos is where you’ll see the best results,” Friese notes.
