While I love my natural hair, I'm always on the hunt for the best volumizing hair products to give my strands more height and dimension. Now, I'm not trying to look like a certain reality television personality (you know who I'm talking about), but I want my hair to have some lift and simply zhuzh it up just a bit. Similar to most of my shopping needs, I turn to popular retailers like Amazon, Target, and Ulta to look for products that may fit the bill, especially when it comes to haircare.

Shampoos and Conditioners
Rating: 4.1 out of 5 stars
Review Highlight: "My hair was being difficult, and as it is thin and fine that can be frustrating. I bought this shampoo and my hair is squeaky clean and really does have volume!”
We Say: This shampoo uses a combination of green tea antioxidants, citrus juices, and lemongrass to remove product buildup and enhance volume.
Rating: 4.5 out of 5 stars
Review Highlight: "Absolutely love this shampoo and conditioner, on my second bottle now. I love trying new conditioners and after running out of my first bottle purchased a different product and noticed a major downgrade in my hair's health, look, and feel within days. Since switching back to this my thin, flat hair looks and feels so much better, gets greasy less frequently, and has much more volume. Will forever use this product."
We Say: "After dealing with years of weak strands after chemically straightening my hair, finding thickening shampoos and conditioners to use as part of my washday routine became a must. This set by L'Oréal Paris is one of my favorites to recommend since it's gentle on damaged, thin hair while injecting strength. I noticed less frizz and breakage after a couple of uses." — Maya Thomas, assistant beauty editor
Rating: 4 out of 5 stars
Review Highlight: "Does not weigh hair down, and I love that you do not have to use a lot of it (just extra water and lather all over). Still leaves hair soft, just adds volume.”
We Say: This sulfate-free shampoo adds shine and volume to those with straight and wavy hair types.
Rating: 4.5 out of 5 stars
Review Highlight: "The BondiBoost Thickening Therapy Volumizing Shampoo & Conditioner Duo is a game-changer for thicker, fuller hair. The shampoo cleanses without stripping, while the conditioner adds volume and softness. Together, they've transformed my hair for the better. Highly recommend!"
We Say: "Finding shampoos that cleanse without stripping and conditioners that add volume without adding weight can be tough, so why not stick with the products that you know will 100% work? This set by BondiBoost has performed wonders for my hair. Its formula features hyaluronic acid and plant actives that offer instant life, thickness, and volume." — Thomas
Rating: 4.5 out of 5 stars
Review Highlight: "I’m a product junkie, so I’ve tried every brand out there, this is probably one of my top three shampoo and conditioners. Aside from the fact that it smells absolutely wonderful, I can actually feel my hair plumping up, in a non-heavy/clean way. I’ve used his styling products in the past but this is my first time using his shampoo and conditioner. I definitely will purchase again in the future!"
We Say: "My mother swears by the Plumping Wash and Rinse Set to give her fine, previously chemically straightened hair the extra oomph it needs. The Plumping Wash provides an effective cleanse and stimulates the scalp for growth while the Pluming Rinse works overtime to amplify the texture and fullness of your tresses." — Thomas
Rating: 3.9 out of 5 stars
Review Highlight: "I was very surprised that as I lathered my hair (two pumps on thoroughly wet hair is plenty) it felt fuller. I know that sounds impossible (and maybe it is a placebo effect), but I swear my hair feels fuller even when wet. Combined with the Nurture conditioner my hair feels fuller, has nice volume, and falls really well.”
What We Say: This sulfate-free shampoo adds body and volume to your strands without drying out your hair thanks to its formula of hemi-squalane, squalane, caffeine, and aloe leaf juice.
Rating: 4.4 out of 5 stars
Review Highlight: "I am so pleased with the Dallas shampoo/conditioner set. I have been using Television for a while and really like that, but decided to try the Dallas line for a change. I have very fine, thin, shoulder length hair. It does not hold a curl. Since I've been using Dallas, my hair feels much more full and soft. I have also noticed my curls stay a bit longer. I will definitely be re-purchasing!"
We Say: "R+Co Dallas Biotin Thickening Shampoo and Conditioner Set, like the rest of the brand's high-performance products, has absolutely transformed the health of my strands post–chemical relaxer. Dallas nourishes and strengthens my hair from root to tip and adds body where I need it when I'm opting for a straight style. It's also perfect for use with hot rollers and curling irons." — Thomas
Mousses and Foams
Rating: 4.2 out of 5 stars
Review Highlight: "It's my favorite mousse. I switched to it after my previously favorite mousse changed its formula, and I was very surprised by the results. I have fine hair, and it gives me very nice volume and hold.”
We Say: Made with aloe vera and vitamin E, this mousse works to shape curls and create volume without adding extra unwanted crunch.
Rating: 4.2 out of 5 stars
Review Highlight: "The product gave me lift and volume without changing the texture of my hair. I usually can only use a product every other day wash. I can go two days now. My hair is very fine but thick. This product is a game changer! Gives my hair lift and volume! Will always be in my regimen."
We Say: "When styling fine hair, volume-and-lift sprays should be your best friend. This one is non-sticky and offers volume, built-in heat protection, and hold for bigger, fuller results. Not only is it incredibly lightweight and long-lasting, but it's safe to use on colored tresses. The formula's use of hydrolyzed keratin and panthenol provitamin B5 are behind its ability to reduce breakage, prevent damage, and moisturize the hair from within." — Thomas
Rating: 4.4 out of 5 stars
Review Highlight: "I'm not really sure how this works, but my hair has been falling out and I already have thin hair to begin with, so it feels like nothing. This foam made me feel like I had double the amount of hair on my head after I blow-dried it."
We Say: "Okay, I say this as someone who used to have a fear of mousses (crunchy, stiff curls make me shudder): You need this foam in your haircare arsenal. For me, it creates the fluffiest, bounciest blowouts that feel light as air and oh-so silky. No crispy curls here!" — Jamie Schneider, senior beauty editor
Rating: 4.3 out of 5 stars
Review Highlight: "I have used this product for years, and even though I no longer color my hair, I rely on this mousse for styling my fine, limp gray hair; it gives my hair the boost it needs, and helps keep my 'do' all day long.”
We Say: This is a weightless mousse that conditions, offers heat protection, and provides weightless volume to hair with just a golf ball–size amount of product.
Rating: 4.5 out of 5 stars
Review Highlight: "I've had a great experience with other Oribe hair products, so I decided to try this mousse. A little goes a long way to add volume to my fine hair, and it smells great, too! Highly recommend."
We Say: "It's always smart to have a mousse on hand for a finishing touch to your style. The Hair Plumping Mousse boosts volume and softness without leaving a stiff finish using Oribe's Signature Complex (a blend of watermelon, lychee and edelweiss), panthenol, and vitamin E." — Thomas
Rating: 4.4 out of 5 stars
Review Highlight: "This volumizing mousse is amazing and smells delicious (soft, not overbearing). The mousse is not sticky, it’s light and fluffy. The whole Davines line is wonderful.”
We Say: This mousse adds natural-looking body and volume to fine and thin strands whether worn up or down by applying to towel-dried hair.
Rating: 4.5 out of 5 stars
Review Highlight: "I love this for creating a '50s movie star look for my hair. It gives me the right amount of volume, without weighing down nor drying out my hair.”
We Say: Not only does this foam enhance volume, but it also works to tame frizz and unwanted flyaways with its formulation of soy protein, hydrolyzed quinoa, and organic acacia senegal gum.
Rating: 4.1 out of 5 stars
Review Highlight: "This stuff is magic…not only did it help me on my way back to pre-pandemic volume, I also noticed that my hair has stopped its stress-induced thinning. It smells great, is lightweight, and I'm convinced it contains fairy dust because WOW. It definitely helped me achieve my big hair goals!”
We Say: With a physician-developed formula, this foam enhances volume for thin strands thanks to its BioPeptin Complex.
Rating: 4.4 out of 5 stars
Review Highlight: "Perfect volume on my fine, but dense hair. Also lasts a very long time. I have used it every day for six months, and it is still going!”
We Say: This styling foam provides volume without unwanted frizz and gives strands a shiny finish ideal for any style.
Rating: 4.4 out of 5 stars
Review Highlight: "Lots of volume, my hair doesn’t feel like there is any product weighing it down. It’s very natural feeling.”
We Say: This best-selling foam is made for those with fine hair to provide extra body and enhance volume by evenly distributing product from root to tip.
Mists and Sprays
Rating: 4.7 out of 5 stars
Review Highlight: "Love this thickening spray for my dry thin hair. It thickens without any residue feeling and without drying it out too much. It's a staple in my routine. I have short, bleached hair and I love using a couple sprays while it's wet and drying with a roller brush."
We Say: "The Hair Thickening Therapy Spray is a must for anyone looking for thicker, fuller, and healthier-looking hair in minutes. Effective for use on all hair types and textures, this lightweight product thickens and expands each strand while adding volume and preventing future damage with a blend of biotin, vitamin B3, and amaranth extract (a natural hair strengthener)." — Thomas
Rating: 4.4 out of 5 stars
Review Highlight: "I love using this Verb volume spray! It is lightweight and adds great volume to my hair! It doesn’t have a scent to it, which works for me because I don’t like strong scents competing with my perfume or body lotion… Well worth trying if you’re looking for volume!”
We Say: Made from sunflower seed extract, the weightless formula easily sprays on hair and enhances volume from root to tip without unwanted weight.
Rating: 4.3 out of 5 stars
Customer Review: "Bumble and Bumble gifted me this product and I'm so excited to finally have a product that actually works for my straight hair! I use it before I blow dry my hair and the volume it gives me hair is unreal. It also doesn't make your hair feel dirty."
We Say: "Bumble and Bumble's Thickening Dryspun Volume Texture Spray is an easy favorite among Who What Wear's beauty editors. Best for fine to medium hair types, the translucent dry finishing volume spray is formulated with a texturizing blend of zeolite and silk powder for volume, hold, and texture. Plus, your hair will smell amazing with a fresh scent of lemon, bergamot, apple, and water lily." — Thomas
Rating: 4.4 out of 5 stars
Review Highlight: "Wow does this product deliver results! Although my hair is fine, there is a lot of it, and it tends to be quite flat. I spray this on the root area, blow dry, and wow, volume and style galore. During the day I can use my fingers to refresh and keep the style for the day. Doesn’t weigh down my hair, and it isn’t heavy at all.”
We Say: This volumizer adds body and volume to fine and limp hair types starting at the root without leaving behind traces of residue.
Rating: 4.3 out of 5 stars
Review Highlight: "I’m impressed by this Texture Spray. It’s great for beach waves and acts like a combination of a dry shampoo and light hairspray. A little goes a long way, so use it sparingly. I tried two of the mini size and immediately bought a full size when I ran out."
We Say: "IGK's Beach Club Volume Texture Spray gives you that salty, beachside hair look without salt ever making contact with your tresses. It's formulated without salt, instead using a mixture of hydrating glycerin for texture and nourishing sunflower seed extract for buildable texture and volume without any crunchiness. It also offers hold and extended styling for the days you don't want to spend playing with your hair." — Thomas
Rating: 4.5 out of 5 stars
Review Highlight: "I love all the Olaplex products and my latest addition of this Volumizing Blow Dry Mist does not disappoint. Gives my hair weightless lift and protects it from heat as I’m blow drying to keep my hair looking it’s healthiest best."
We Say: "Using Olaplex's Volumzing Blow Dry Mist is one of my favorite ways to create body and volume while also providing heat protection up to 450°F, eye-catching shine, and strength and style retention. The bouncy blowouts you create at home will never look better." — Thomas
Rating: 4.5 out of 5 stars
Review Highlight: "I have very fine hair and need that extra volume of a texture spray, but hate that so many are sticky to the touch even hours after you spray them onto your hair… I’m not sure why it took me so long to try their texture spray, but I’m glad I finally did as it is the only one I have tried that doesn’t give me that sticky-to-touch result with the volume I want.”
We Say: Made with argan oil and wheat proteins, this texture spray helps to style and add volume to hair without leaving residue.
Rating: 4.5 out of 5 stars
Review Highlight: "Tons of volume that's easy to work with and holds all day. If I want the rest of my hair to hold a curl, I put it in a bun overnight and it works like a charm! I get my hair done in three minutes in the morning.”
We Say: Adding volume to strands is just one of many benefits of this spray made with sunflower seed extract and chamomile extract. It also works to hold hair styles, add shine, and provide UV protection.
Rating: 4.2 out of 5 stars
Review Highlight: "I have always had fine, thin hair. When I wash and style it I find it looks full and keeps its curl. In the past, just a little while later, it was flat, lifeless and not holding its style. Adding this product prior to styling my hair, it not only looks fuller, but the fullness and style stays longer—at least two to three days which allows me to go longer between shampooing my hair. A quick restyle in he morning and I'm ready to go."
We Say: Made for all hair types, this vegan spray adds volume and shine to strands for optimal styling and daily wear.
Rating: 4.4 out of 5 stars
Review Highlight: "After one use, I can tell it does exactly what I was hoping for. It added volume and texture to the dry hair on top of my head to match the volume and body of the rest of my hair. We’ll see if it lasts throughout the day or for days to come, but so far I’m very happy!”
We Say: Whether you’re looking to create an intricate hairstyle or add some volume to your daily down look, this silicone-free spray does it all.
Rating: 4.4 out of 5 stars
Review Highlight: "I wash my hair at night, put in the mousse, and let air dry overnight. In the morning I brush through the 'stiffness' and then use a curling iron to style. This mousse gives great volume and holds my style nicely. I get lots of compliments on the bounce and volume of my hair.”
We Say: This is a long-lasting mousse that will give hair volume for up to 24 hours while offering heat protection and a soft finish.
Rating: 4 out of 5 stars
Review Highlight: "It is important to spray into wet hair, rub a bit, and blow dry normally. The result is just great! Even the next morning, the hair still has volume.”
We Say: Use this spray before styling for a mane with enhanced volume that’s left with a sweet fruity fragrance of pineapple and blackberry.
Rating: 4.2 out of 5 stars
Review Highlight: "Great for my super thin hair. It isn't sticky like a lot of the volume builders, but gives my hair a nice volume that still looks great on day two. Best I have found so far.”
We Say: An ideal spray for those with fine and thin hair who want to secure a voluminous finish after a complete blow-dry.
Rating: 4.3 out of 5 stars

Scalp Serums
Rating: 4.1 out of 5 stars
Review Highlight: "Ive been using this serum for just over a month and its been a game changer. My hairline has noticeably filled in and my hair feels thicker. I'm losing the same amount of hair in a month that I used to lose every week. It doesn't feel heavy or have a strong smell either."
We Say: "Hair of all types and textures can benefit from addition The Ordinary's Multi-Peptide Serum to help boost density. While transitioning my hair from being chemically straightened back to its natural coils, I saw a major difference in its fullness after using this lightweight, water-based serum daily over the course of three months. Simply add a few drops to the scalp, and massage in for healthier-looking hair." — Thomas
Rating: 4.6 out of 5 stars
Review Highlight: "The Hair Density Boosting Treatment is my new holy grail product. After eight weeks of daily use, my wavy hair is noticeably fuller and sheds less. The serum is lightweight, easy to apply and leaves no greasy residue—just a pleasant fragrance. A must-have for healthier, thicker hair!"
We Say: "I love treating myself to Aavrani's Hair Density Boosting Treatment as part of my Sunday beauty refresh. It's a weightless leave-in serum that visibly improves hair density, addresses fallout, and has a lightweight texture with a non-greasy or -sticky feel. The formula includes turmeric stem cells to help "reset" the hair bulb, vegan collagen to boost hydration, and ashwagandha to strengthen to roots and alleviate scalp irritation." — Thomas
Rating: 3.9 out of 5 stars
Review Highlight: "I’m really loving this product! I’ve used the serum consistently for almost two months. I’m seeing my baby hairs filling in around my temples where I had thinning hair. I have fine hair so after I apply the serum I use a little dry shampoo to lift my root and I think it works great!"
We Say: "While I use a number of Briogeo's products, its Destined for Density Peptide Hair Serum is by far one of my favorites. Perfect for use on all hair types and especially effective for fine textures, this lightweight serum promotes thicker, fuller hair with a non-greasy finish. Its formulated with the Briogeo Nova Complex, which works to stimulate the scalp and strengthen hair while combating shedding and loss of density." — Thomas
Rating: 4.5 out of 5 stars
Review Highlight: "This is one of the nicest hair serums I have used! The scent is very light and clean and the packaging was great! The serum is not super thick or oily, so it really penetrates to the scalp rather than just sitting on your hair. I’ve been struggling with hair loss after having my baby and I already see some progress being made with the Nécessaire serum!"
We Say: "As someone who absolutely loves Nécessaire's line of body products, I had high hopes for the brand's haircare line that were easily met. The Scalp Serum, for example, has a formula that combines vitamin B3, B5, and hyaluronic acid among other superpowered ingredients to address dryness, shedding, and dry scalps for all hair types and textures." — Thomas
Rating: 4.3 out of 5 stars
Review Highlight: "This serum is great, super lightweight, smells great, leaves no residue. It leaves your hair feeling thicker and hydrated. I use this on my dry hair after blow drying and it has greatly protected my ends from damage. I would buy this product over and over again!"
We Say: "If you're using Shu Uemura's Izumi Tonic Hair Mask, you might as well add its rice water serum to your product lineup. Like the hair mask, this serum is infused with Japanese-sourced rice water clinically proven to leave hair 30 times stronger and reduce split ends up to 91% while protecting against future damage." — Thomas
Rating: 5 out of 5 stars
Review Highlight: "I'm on a mission to heal my hair and this has been a critical item in my lineup. I usually put it on pre-workout and let it do its magic for about an hour. It washes out cleanly and leaves my scalp feeling refreshed."
We Say: "Trust me—don't look at the price tag; look at all the benefits! Dr. Barbara Sturm's innovative Scalp Serum uses nourishing ingredients like ATP, algin, and papaya extract to restore the scalp's moisture balance and sooth irritated skin.
