The 10 Best Hair-Thickening Shampoos of 2024
Hair-thickening shampoos can take limp and lifeless tresses and transform them into lifted and voluminous locks. Whether your hair is color-treated, dry, or damaged, there's a thickening shampoo formula that can tackle your hair concerns.
“Some thickening shampoos contain properties that make the hair ‘swell’ so that it feels plumper and more full when styling, whereas others target the scalp with nourishing ingredients that stimulate the follicles to increase hair growth and density,” says celebrity hairstylist Justine Marjan.
For our list, we focused on the former but did include one option that promotes actual hair growth. To find them, we spent hours researching formulations, ingredients, and compatible hair types. We also spoke more with Marjan for guidance on what to consider when shopping for the best hair-thickening shampoo.
