For most of us, hair is a big part of our identity. It’s one of the most visible aspects of our appearance, and there are so many ways to experiment and express ourselves through our hair. That’s why you shouldn’t settle for dull and flat strands—especially when there are so many products out there that can help you achieve better volume, shine, and bounce.

It’s true; the right hair care routine can transform fine, damaged hair into healthy, fuller-looking locks. And one of the easiest places to start is with your shampoo. Find a formula with nourishing ingredients like vitamin B5 and biotin (both of which hydrate and strengthen the hair), and you'll be well on your way to healthier, shinier strands in no time.

But don't fret—we won't make you find them yourself. Ahead, we've rounded up a list of the 10 best hair-thickening shampoos on the market, all fortified with ingredients that'll create a healthy scalp environment and set the stage for your fullest locks yet. Whether you were born with fine hair or are recovering from years of coloring and heat damage, the formulas below have you covered.

Here’s Why You Can Trust Our Top 10 Lists

Let’s start with this: there isn't actually a way to increase the thickness or density of your hair. However, there are products that can create the appearance of full, voluminous locks—and many have gone before you to test the credibility of their claims. That’s why we called upon our data-powered ranking algorithm to comb through the reviews for different hair-thickening products in order to find out which ones truly deserve the title of best. With the help of information from other sources (such as best-seller lists and social media), this unbiased tool identified the 10 shampoos below as the best options for fine, thin hair.
