From shampoos, conditioners, and leave-ins to sprays, lotions, powders, and pomades, there's something for everyone, every budget, and every fine hair-related concern.
Without further ado, here are the best hair-thickening products you can buy today.
Best Overall: Oribe Maximista Thickening Spray
Coming in hot as our number one pick, we've got Oribe Maximista. Working overtime to lift your roots and add all-day volume while protecting your strands from heat and UV rays, this thickening spray has a well-deserved cult following. 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 fullness.
Best Budget: Garnier Fructis Mega Full Thickening Lotion
You don't have to spend a lot of money to make your hair look and feel thicker, thanks to this standout lotion from Garnier. The sheer formula creates fullness, body, and shine without weighing your hair down, which can make it look flat and limp. Bonus: It's made with cotton flower extract to make your strands bouncy and silky-soft—never tacky.
Best Drugstore: Not Your Mother's Plump For Joy Thickening Hair Lifter
If you have fine, lifeless strands, this plumping spray is just what the doctor ordered. It lifts and revitalizes thin strands, adding volume, body, and a little bounce. Not only that, but this thickening product strengthens your hair to prevent breakage and fall-out over time.
Best Splurge: Oribe Serene Scalp Thickening Treatment Spray
If you're open to splurging on a truly promising product, we recommend Oribe Serene Scalp. The spray-on treatment fortifies every strand, delivering fuller, thicker tresses. With standout ingredients like biotin and niacinamide, plus peptides and phytonutrients, this product replenishes fine, brittle hair and makes it look nourished.
Best Strengthening: Kevin Murphy Full Again Thickening Lotion
Kevin Murphy Full Again is a favorite of Las Vegas-based hairstylist Haley Balayage, and we can see why. "It contains particles of rayon used to help surface hair appear thicker and to help finer hair act thicker. The entire KM thickening line is great for hair types that need a little boost," she says.
Best Texturizing: Bumble and Bumble Thickening Dryspun Volume Texture Spray
To give thin strands a little oomph, reach for Bumble and bumble's Thickening Dryspun. Whether you want thick, beachy waves, a fuller updo, texturized curls, or just a refresher for second-day hair, this spray has you covered. It adds the perfect amount of dimension and body with a lifted, airy effect.
Best Shampoo: OGX Thick & Full Biotin & Collagen Shampoo
Styling products can go a long way, but you might want to kick off your hair-thickening routine in the shower. This velvety-smooth shampoo from OGX contains biotin and collagen, plus hydrolyzed wheat protein for a fuller, plumper, healthier-looking mane with every wash.
Best Conditioner: R+Co Dallas Biotin Thickening Conditioner
As the saying goes, everything's bigger in Texas. Your hair can get in on the action when you use R+Co's Dallas conditioner. Made specifically for people with thin, fine strands, the volumizing formula expands your strands and pumps them with perfectly soft volume.
Best Spray: John Frieda Volume Lift Thickening Spray
For salon-level hair at drugstore prices, John Frieda won't let you down. This thickening spray lifts flat strands from the roots to deliver noticeably fuller, natural-looking volume. Spray it onto towel-dried hair, focusing on your roots, then work it through with a comb and style as usual.
Best Pomade: Qhemet Biologics Castor & Amla Nourishing Pomade
Sometimes all fine hair needs is a little nourishment. With this in mind, Qhemet Biologics made this pomade. The vegan formula, containing a blend of castor oil and ayurvedic amla oil, hydrates, softens, strengthens, and thickens your hair while reducing shedding and encourages growth.
Best Mousse: Keranique Thickening & Texturizing Mousse
We're also big fans of this biotin-infused thickening mousse. It's formulated with a special keratin-amino acid complex, gives your hair body, and coats each strand with a protective treatment. The result? Smooth, hydrated hair, reduced breakage, and a thicker-looking mane.
Best Powder: SexyHair Powder Play Volumizing & Texturizing Powder
Fine hair often coincides with flat hair. To give your hair the fullness it deserves, you'll have to lift it with a texturizing formula, like this one from SexyHair. Powder Play minimizes the slickness that can weigh down the hair and builds it up with dimension and volume. The translucent powder is easy to use and won't leave your hair flaky. Just sprinkle it onto your roots and watch it liquify then absorb into your hair, expanding each strand.
Best Oil: Mielle Organics Rosemary Mint Scalp & Hair Strengthening Oil
You might have to play the long game to achieve truly thicker hair, and this strengthening oil from Mielle is here to guide you through. The nutrient-rich blend is infused with biotin and contains upwards of 30 essential oils. It nourishes each strand, hydrates every follicle, smooths split ends, and supports growth.
Best Cream: Living Proof Full Thickening Cream
If Jennifer Anniston, the hair goddess herself, didn't convince you of the powers of Living Proof when she was the face of the brand, allow us to sway you. Lack of texture can make hair appear thin and flat, and this cream addresses the issue with finesse. Formulated with the brand's patented thickening molecule, it deposits teensy-tiny dots on your strands, making them look bigger and fuller. Not only that, but a creamy emollient blend creates a stunningly soft sheen.
What Our Testers Say
"I love that the cream made my hair look fuller whether I was wearing it down or just wanted to boost a simple ponytail. It actually felt like it made my hair healthier rather than just increasing volume, and for that, I think it's a must-have for thicker hair." — Joline Buscemi, Product Tester
Best Gel: Nioxin 3D Styling Thickening Gel
Nioxin Thickening Gel isn't like other gels. It creates texture and fullness in thinning or otherwise fine hair and holds your style in place without leaving it sticky, crunchy, or stiff. Formulated with bonding polymers that wrap around your individual strands, you can count on noticeably thicker hair and impressive volume.
Best Clean: Briogeo Blossom & Bloom Ginseng + Biotin Hair Volumizing Spray
If you like to keep your hair clean with minimal ingredients, you can't go wrong with Briogeo Blossom & Bloom. This double-duty thickening spray maximizes fullness while delivering long-term hair benefits. The secret ingredient? Maltodextrin. The all-natural sugar starch coats each hair to deliver dramatic volume. Thanks to biotin and ginseng, this formula helps grow long, strong strands.
If we had to pick just one hair-thickening product, we'd go with Oribe Maximista Thickening Spray. This trusted standby lifts your roots, protects your strands, and delivers incredible 24-hour volume. However, if you'd like to limit your hair care spend, Garnier Fructis Style Mega Full Thickening Lotion is a solid choice. Your hair will look and feel thicker with all the fullness you covet.
What to Look For in a Hair Thickening Product
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.
