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.

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,

So, 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. We also took our editors' experiences with thickening products into consideration to help solidify our list. Our team then combined our insights to compile a list of the best thickening products based on formula, application, results, and hold. Ahead, find our top recommendations.

Best Overall

Oribe Maximista Thickening Spray

4.6
Oribe Maximista Thickening Spray

Amazon

What We Like
  • Long-lasting volume

  • Strengthening

  • UV protection

What We Don't Like
  • Can get sticky if over-applied

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.

Kristin Ess Instant Lift Thickening Spray

Kristin Ess Thickening Spray

Target

What We Like
  • Promotes shine

  • Good for all hair types

  • Helps smooth the appearance of split ends

What We Don't Like
  • Can be drying if over-applied

Our favorite budget-friendly hair thickening option is this thickening spray from Kristin Ess. It's a lightweight spray that's meant to be applied on towel-dried hair before blowdrying to add body and lift to the roots and lengths of the hair. It also works to add shine and help smooth the appearance of damage and split ends. If you have dry hair, we recommend just using a bit and finishing off your style with a hydrating hair oil.

Best Splurge

Oribe Serene Scalp Thickening Treatment Spray

Oribe Serene Scalp Thickening Treatment Spray

Dermstore

What We Like
  • Noticeable results

  • Supports healthy growth

  • Strengthening

What We Don't Like
  • Not ideal for those who don't wash their hair somewhat frequently

If you're open to splurging on a truly promising product, we recommend Oribe Serene Scalp. The spray-on treatment fortifies with biotin and peptides to promote healthy growth, then coats every hair with copolymers to deliver a fuller, thicker head of hair.It's a great option if you want convenient application, but it's worth noting that it needs to be applied on clean, damp hair and used consistently to produce results, so it's not ideal for people who go long periods in between washes.

Product Type: Treatment spray | Key Ingredients: Biotin, peptides, thickening copolymers | Size: 4.2 ounces

Best for Thinning Hair

Vegamour GRO Hair Serum

Sephora

  • Lightweight texture

  • Great for all hair types

  • Non-greasy

  • Is best as a spot treatment

If you're looking for a product help you thicken a specific spot or area that's thinning (rather than helping to achieve the appearance of thicker hair overall), this is the one for you. The vegan serum is formulated with turmeric, nicotiana benthamiana (a plant native to Australia), and red clover to help promote hair growth and prevent hair loss. Thousands of reviewers have seen incredible results with this best-selling serum, and it's a great option for all hair types.

4.3
Living Proof Full Thickening Cream

Sephora

What We Like
  • Noticeable results

  • Softening

  • Conditioning

What We Don't Like
  • Pricey for the amount of product given

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 the hair appear thin and flat, and this cream addresses the issue with finesse. Formulated with the brand's mysterious yet effective "thickening molecule," it deposits teensy-tiny dots on your hair, making it look bigger and fuller. We also love that a little bit goes a very long way, really adding to the value of the product.

Price at time of publish: $17, $30

Product Type: Leave-in cream | Key Ingredients: Thickening molecule, emollient blend | Size: 2, 3.7 ounces

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

To give thin hair a little oomph, reach for Bumble and Bumble's Dryspun Spray. This product has you covered, whether you want beachy waves, a fuller updo, texturized curls, or just a refresher for second-day hair.

What We Like
  • Instant fullness

  • Strengthening

  • Supports healthy growth

What We Don't Like

This double-duty thickening spray maximizes fullness while offering long-term healthy hair benefits. The secret ingredient? Maltodextrin. The all-natural sugar starch coats each hair to deliver dramatic volume. It also contains biotin for long, strong hair.Note that while lots of hair spray products are applied on dry strands, this formula should be applied on damp hair prior to blowdrying.

  • Supports healthy growth

What We Don't Like
  • Not ideal for air-drying

Alterna's Multiplying Volume Mist coats your hair with a smoothing, strengthening blend of keratin, biotin, and amino acids, while algae and kelp plump the individual strands. Though it can be stiffening if you allow your hair to air-dry, a few spritzes before you blow-dry will yield smooth, stunning results.

What to Look for in Hair Thickening Products

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. If a nourishing option is what you're looking for, consider the Qhemet Biologics Castor & Amla Nourishing Pomade. 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. If you're looking to thicken specific spots that are thinning, try a hair growth serum like the Vegamour GRO Hair Serum for Thinning Hair.

  • 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, unless you have extremely oily hair. Instead, rinse your hair and use a thickening conditioner or other thickening product.
