21 Best Shampoos for Thinning Hair 2022 to Make Hair Look Thicker and Healthier | Expert Reviews

Ginger King, a cosmetic chemist and founder of Grace Kingdom Beauty, also recommends looking for shampoos that tout their “styling” capabilities as they work more like styling hairsprays. These shampoos typically contain what King refers to as film formers, which are ingredients like acrylate copolymer. “There are also silk proteins and keratin proteins that can help to add a moisturizing layer for hair to look thicker,” says King.

Lastly, King cautions against products containing silicones if your main concern is thinning hair. “Personally, I am not opposed to the use of silicones in hair care, but for people who have thinning hair, silicones can build up and weigh hair down,” she says.

Below, read about the 21 best volumizing shampoos and fortifying formulas for all hair types. Best of all, you don’t need a prescription to scoop any of these up.

Hair Biology Biotin Volumizing Shampoo

Like your skin, your hair is susceptible to signs of aging. But instead of crow’s feet, laugh lines, and sun spots, your hair deals with things like breakage, thinning, and brittleness. Thankfully, Hair Biology is a brand designed to address these concerns, starting with the Biotin Volumizing Shampoo. This shower must-have is made with biotin for shinier, fuller-looking hair, and it’s also safe for color-treated hair. You’ll get a rich lather out of this one, which is great for those needing a deep clean to get rid of dirt, oil, and product buildup. And, to top it all off, it’s only $10 bucks.

The Andrew Fitzsimons Body Volume Boosting Shampoo contains caffeine to help hair appear thicker, all while maintaining shine and softness. For this, we awarded it a 2022 Best of Beauty Award. Oh, and because it smells like a high-end hair salon.
