If thinning hair is taking a toll on your confidence, investing in a hair-thickening shampoo is an easy and low-stakes way to target the issue, which stems from genetics, stress, hormonal shifts such as menopause, temporary illnesses like Covid, and poor nutrition. Hair-thickening shampoos contain volumizing ingredients like polymers or resins that adhere to the hair strand, increasing the diameter to make it appear thicker and create the illusion of fuller hair, explains Jennifer Korab, a celebrity hairstylist. Thickening shampoos may also contain ingredients that help increase blood flow for growth stimulation, says Mandy Buechner, a certified trichologist and hair loss practitioner. "Some ingredients to look for in a shampoo to help with thinning are saw palmetto, rosemary, or nettle," she says. There are also ingredients to stay away from, like harsh sulfates or alcohol, which can be too drying, adds Korab.

All hair types experiencing hair thinning can benefit from a hair-thickening shampoo. "If you have finer hair, you may want to use the shampoo daily and follow with only a little conditioner so you don't weigh down the hair," says Korab. "For more coarse or oily hair, you may choose to shampoo every other day." Ready to shop for hair-thickening shampoos to add to your routine? Keep scrolling for expert-approved options.
