What to Look For in a Hair Thickening Product

Intended Use

The main thing to look for when buying a hair-thickening product is its intended use. Look for the words "thickening," "volumizing," "strengthening," "texturizing," "full," "plump," or "lift" in the name or on the label. These terms usually mean a product is formulated to actually thicken the hair or at least make it look thicker.


Hair-thickening products come in many forms. There's shampoo and conditioner, plus lotions, sprays, mousses, pomades, powders, and treatments. While you can definitely stock up with one of each type, we recommend considering the unique needs of your hair and the look you're going for to figure out what'll work best.

"I would look for anything that adds fibers to the hair. It's the best bet to be sure that the hair itself will actually expand in size," says Balayage. Texturizing formulas often deposit product onto the hair and wrap around the strands to create a fuller look. Volumizing formulas typically penetrate the strands to plump them from the inside out.


The ingredients list can tell you a lot about how a product works and whether it can live up to its claims. Hair-thickening products are often made with ingredients like biotin, collagen, amino acids, zeolite, peptides, and niacinamide, which help strengthen and plump the follicles and promote growth.

You might also see options with castor oil or essential oils, which can help nourish the scalp and help hair grow in fuller. Then with texturizing sprays and powdery formulas, you'll want to look for thickening agents like silica silylate and starchy ingredients like maltodextrin or silk powder.
