Thinning hair can happen to any guy—maybe it’s happening to you right now. The process comes naturally with age, but there could be another reason you’re experiencing flat, volume-less hair: “A lot of guys’ hair actually starts thinning because it’s unhealthy,” says grooming expert David Pirrotta. This can be due to over-shampooing, or just using the wrong products.
Sometimes, improving your thinning hair can be as simple as switching to a thickening shampoo. Active ingredients in the shampoo deposit a thin film on top of the hair strands, making your hair look fuller and healthier, Pirrotta explains.
Here are 10 expert-approved shampoos that can help make you a little more confident in what’s on top of your head.
