Whether you've always had fine hair, or are experiencing thinning due to stress, hormonal changes, or aging, over-the-counter hair thickeners can add volume, body, and fullness to your hair.

Byrdie Researched & Approved

Our best overall pick is Oribe's Maximista Thickening Spray, which contains copolymers to create fullness and amino acids to strengthen. We also love that it provides protection from both heat and UV rays. For a more affordable option, consider Garnier's Mega Full Thickening Lotion, which also contains copolymers to create body without weighing down hair.

Lots of brands and product lines make big claims about their ability to fortify, lift, plump, and pump your hair with volume—or at least make it appear more voluminous. They might seem too good to be true—and yeah, some are—but we found a handful that do what they say. From shampoos, conditioners, and leave-ins to sprays, lotions, powders, and pomades,

We went to work, conducting research on the best hair thickening products from shampoos, conditioners, and leave-ins to sprays, to lotions, powders, and pomades. Our product testers tried out some of the top-rated products, using them for weeks at a time and taking note of results. Our team then combined these results with our own research and stylist-recommended products to compile this list.

Ahead, find the best hair-thickening products to add volume and body.

Best Overall: Oribe Maximista Thickening Spray

Oribe Maximista Thickening Spray
What We Like
  • Long-lasting volume

  • Strengthening

  • UV protection

What We Don't Like
  • Pricey

Who else recommends it? Women's Wear Daily and Who What Wear both picked the Oribe Maximista Thickening Spray.

What do buyers say? 82% of 1,900+ Amazon reviewers rated this product 4 stars or above.

Coming in hot as our number one pick, we've got Oribe Maximista, which calls on copolymers to create fullness and amino acids to strengthen each hair. Working overtime to lift your roots and add all-day body—while protecting your hair from heat and UV rays—this thickening spray has a well-deserved fan following. The price point is high, but because of the protein-rich formula, we think the price is justified, especially if you use heat styling on your hair.

We also like that it's safe for keratin blowouts and color-treated hair. Spritz it onto your damp hair, working through one section at a time, then blow-dry or style as usual, and watch as your hair reaches a new level of volume.

What to Look For

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 thicken the hair or at least make it look thicker.

Formula

Hair-thickening products come in many forms. There's shampoo and conditioner, plus lotions, sprays, mousses, pomades, powders, and treatments. While you can 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 expand in size," says Balayage. Texturizing formulas often deposit product onto the hair and wrap around each hair to create a fuller look. Volumizing formulas typically penetrate each hair strand to plump them from the inside out.

Ingredients

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 (vitamin B3), 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. 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.

FAQ
  • What products help hair thicken?

    Products that help hair thicken include shampoos, conditioners, masks, leave-in creams, weightless mists, and scalp treatments. Check for specific hair thickening ingredients. Look for options containing copolymers, maltodextrin, Chinese skullcap, redensyl, or rayon for instant results.

  • How do I make my hair thicker?

    You can make your hair thicker with hair thickening products, styling techniques, and (possibly) nutrition strategies. Hair thickening products can create the appearance of thicker hair while also nourishing your hair to provide strength and resilience against thinning and breakage.

  • Does biotin thicken hair?

    Biotin may thicken hair. However, the evidence is limited and inconclusive. The good news is that biotin is a nutrient that offers other benefits and cannot harm hair, so adding it to your routine may provide benefits without drawbacks.

  • Should I use hair thickening shampoo every day?

    Using thickening shampoo every day is not typically recommended. This is because shampooing cleanses the hair and often removes natural oils. Using any type of shampoo every day is not ideal for most hair types. Instead, rinse your hair and use a thickening conditioner or other thickening product.
