What Causes Fine Hair?
Just like other hair types and textures, fine hair is largely determined by genetics. However, Jay Small, a trichologist and co-founder of Arey, says these characteristics aren’t “fixed for life” and that hair can fluctuate, depending on lifestyle, environmental, and health factors. “As we age, nutrient deficiencies, stress, and hormonal shifts can significantly influence how thick or resilient our hair appears.” Small explains that individuals who are nutrient-deficient or taking certain medications may notice slower growth, finer strands, or increased brittleness. “In many cases, this can be improved with targeted supplementation, scalp-focused topical treatments, or adjustments to medication under medical guidance.”
As a trichologist, Smalls treats a lot of patients with thinning hair concerns, which can often result in finer strands. “One of the most common contributors I see to changes in hair thickness is hormonal imbalance,” he notes, explaining that hormones such as DHT play a major role in hair density. “When DHT levels are elevated or when follicles are especially sensitive to it, the follicle can gradually shrink.” As a result, those smaller follicles create finer strands of hair with shorter growth cycles, which means they might not grow as long or as full as they once did. “Without addressing or balancing the underlying hormonal activity, these hairs can continue to become finer over time,” Smalls adds.
Hair that isn’t already fine to begin with can also appear finer due to chemical, environmental, and mechanical stress. “Unlike skin, the hair you grow today remains with you for years, depending on its length,” Smalls notes. He explains that styling and lifestyle habits like repeated coloring, highlighting, heat styling, blow drying, and UV exposure can reduce the diameter of each strand. “For clients already prone to fine hair, these external stressors can make a noticeable difference in fullness and overall hair health.”
How to Make Fine Hair Look Thicker, According to Hair Pros
Whether you were born with fine hair or your hair has become thinner over time, there are some ways to create the illusion of a thicker, fuller ‘do while also supporting hair health. Here are expert-approved fine hair hacks for making strands appear thicker and more voluminous.
Add a Scalp Serum to Your Routine
If you’re concerned about shedding, scalp health, or hair growth, a scalp serum might change the game for you. Over-the-counter options such as the Vegamour GRO+ Advanced Hair Serum can create an optimal environment for hair health, which can lead to hair growth. Additionally, these types of scalp serums are typically formulated to reduce shedding and give the roots a density boost.
Vegamour GRO+ Advanced Hair Serum
On Sale 54% off
An OTC scalp serum can work wonders on your hair health, starting at the roots. Add a formula such as the
GRO+ Advanced Hair Serum from Vegamour to your routine to reduce shedding, boost hair density, and promote hair growth. This serum is also enriched with nourishing ingredients such as peptides and clover sprout extracts that can block DHT (the hormone that shrinks follicles and can lead to hair loss) and the brand’s GROActive+ Complex™ to boost density and reduce shedding, for healthier hair overall.
Limit Stress From Chemical Treatments & Styling
Since fine hair is more prone to breakage, Smalls says to try to minimize stress from chemical treatments and daily styling. “Limiting bleaching, permanent coloring, and other chemical treatments can help preserve the strength and thickness of finer strands,” he explains. “These services typically require a developer that opens the hair’s cuticle to change its color, and repeated exposure can gradually weaken the fiber.”
If you heat style your hair, it’s always best to shield strands with a heat protectant spray, such as the Olaplex Volumizing Blow Dry Mist, and try to extend the life of your style as much as possible. Some hair styling tools, like the Dyson AirWrap or T3 Aire 360 can also reduce damage while still giving you a salon-worthy look.
Dyson AirWrap
On Sale 26% off
Limiting heat styling doesn’t mean letting your hair air dry. You can still get a salon-worthy blowout (and volume) when you use the
Dyson AirWrap. This hair styling tool uses airflow and low heat to style strands.
T3 Aire 360
On Sale 17% off
For a less expensive option, consider the
T3 Aire 360. While it doesn’t come with as many attachments, this is a little more compact compared to the Dyson, making it a great pick for travel, too.
Olaplex Volumizing Blow Dry Mist
Before styling, make sure to apply a heat protectant spray such as the
Olaplex Volumizing Blow Dry Mist to your strands. This protects against high temperatures up to 450°F and includes nourishing ingredients to promote healthier hair.
Be Gentle With Wet Hair
Some things you don’t think twice about might be causing more harm than good. This is particularly true for how you handle wet hair. According to Smalls, hair is significantly more elastic when wet, and it can stretch nearly twice as much as when dry. This makes it much more vulnerable to breakage if not handled gently. “Rough detangling, brushing, or aggressive blow-drying while the hair is sopping wet can compromise its integrity over time,” says Smalls. “Instead, gently towel-blot, use a wide-tooth comb or detangling brush, and allow the hair to partially air dry before applying heat.”
If you want a budget-friendly wide-tooth comb that you’ll literally have
forever, consider the
Vocoste Wide Tooth Comb. This under $10 comb helps gently loosen tangles without pulling and tugging.
Kitsch Microfiber Hair Towel
Towel drying your hair is much easier and more efficient when you use a microfiber towel like the
Kitsch Microfiber Hair Towel.
UNbrush Detangling Hair Brush
Don’t love combing out your hair? A detangling brush like the
UNbrush is a great alternative. This feels a lot like brushing your wet hair, but with
much less damage.
Volume Begins With the Right Shampoo
If you’ve noticed your hair appears flatter a few days post rinse and repeat, it’s because grease can literally weigh your hair down. But, it’s not enough to wash your hair with anything—you’ll want to choose the right shampoo for your needs. “What most people don’t realize is that the scalp ages six times faster than the skin on our face,” says Smalls, adding that the products we use can play a major role in that. With that in mind, he recommends using a proactive shampoo that supports scalp health, encourages hair growth, and enhances the volume and texture of the hair you already have. “When the scalp is balanced and nourished, the hair naturally lifts and styles with much more ease.”
When it comes to products for fine hair, Virtue is one of our go-tos—and we love the Full Shampoo, which is a lightweight formula that helps literally build volume. We also love the JVN Embody Volumizing Shampoo, which clarifies the scalp and instantly strengthens strands with hemisqualane.
JVN Embody Volumizing Shampoo
The
JVN Embody Volumizing Shampoo is one of the best volumizing shampoos we’ve ever tried. It’s enriched with nourishing ingredients such as aloe for hydration, caffeine for hair growth, and hemisqualane, which
literally strengthens strands after just the first wash.
Thicken things up with the
Virtue Full Shampoo. This shampoo is a weightless formula designed with Alpha Keratin 60ku® protein to promote hair growth while also plumping strands for a more thicker-looking finish.
Support Hair Health With Supplements
Healthy hair requires ample nutrients. Even if your fine hair is genetic and not caused by any external factors, ensuring your body has the proper nutrients needed to produce healthy and thick hair is essential. “Vitamins, minerals, and antioxidants play a key role in supporting the hair growth cycle and the follicle’s metabolic activity,” says Smalls. As the founder of Arey, he recommends Not Today, Grey because “it provides a well-balanced blend of nutrients designed to support overall hair growth and resilience from within.” We’re also big fans of the Nutrafol Hair Growth Nutraceutical, which has helped support our fine hair by not only promoting growth but reducing breakage, too.
Hers Biotin + Minoxidil Gummy for Hair Regrowth
This prescription strength
Hers gummy is a two-in-one formula that combines biotin for overall hair health, plus minoxidil to regrow hair in three to six months, making it a great choice for those experiencing fine hair from hair loss.
The
Arey Not Today, Grey is an excellent supplement to try if you want to up the ante on hair-benefiting nutrients. In addition to strengthening strands, it’s also designed to slow gray hair growth and signs of aging within the hair.
Nutrafol Hair Growth Nutraceutical
Promote hair growth with one of our go-to hair growth supplements from
Nutrafol. This hair supplement is designed to target the
root (pun intended) cause of hair loss, including hormones, stress, lifestyle, metabolism, nutrition, and aging.
Protect Fine Hair From UV Damage
In addition to styling, daily stressors such as UV exposure can also wreak havoc on fine hair and, according to Smalls, can “weaken the fiber, gradually decreasing thickness and making it harder to achieve volume.” Because of that, it’s worth using a lightweight, non-greasy UV protectant such as Arey Live In Mist or R+Co Sun Catcher Power C Nourish + Refresh Styling Spray. Covering hair up with a UPF-rated hat like the Solbari Ultra Wide Brim Hat UPF 50+ can also keep locks protected.
R+Co Sun Catcher Power C Nourish + Refresh Styling Spray
The
R+Co Sun Catcher Power C Nourish + Refresh Styling Spray is like a dose of SPF for your hair. This formula features tons of vitamin C and other antioxidants that can protect hair from harsh UV rays and other environmental aggressors like pollution. Plus, it doubles as a heat protectant spray.
The
Arey Live In Mist is another great choice for hair sun protection. It’s enriched with raspberry seed oil, a natural ingredient that helps protect against the sun’s UV rays.
Solbari Ultra Wide Brim Hat UPF 50+
When in doubt, cover up your hair (and your face) with a UPF-rated sunhat like the
Solbari Ultra Wide Brim Hat. This hat features a wide brim with UPF 50+ and can protect your hair from sun exposure.
Blow Dry Your Hair Upside Down
The way you style your hair can give you tons of volume—even if it is super fine. For an instant lift, “flip your head upside down when blow-drying,” says hairstylist Mia Santiago. You can also use a volumizing blow-dry spray such as the Lolavie Peptide Plumping Volume Spray. And, investing in a high-quality blow dryer with enough power to lift those strands also helps. We love the Laifen Swift Se Lite High Speed Hair Dryer.
Lolavie Peptide Plumping Volume Spray
Before flipping your head upside down, give your strands a spritz of the
Lolavie Peptide Plumping Volume Spray. This volumizing bow out spray is designed with peptides to give hair a bit more bounce that lasts a couple of days.
Laifen Swift Se Lite High Speed Hair Dryer
On Sale 33% off
To protect your hair, make sure you’re using a high-quality blow dryer, like the
Laifen Swift Se Lite High Speed Hair Dryer. This one is designed with ionic technology to reduce frizz and boost shine.
Switch Up Your Part
If you want to create the illusion of thicker hair, Santiago has a genius parting hack. Instead of a straight part down the middle—or even down the side—she recommends using the power of “a zig-zag part to fake thickness.” With Y2K and early 2000s fashion back in style, this will even elevate your ‘do with some added interest and make even a straight style appear more unique.
9 Inch Rat Tail Comb (3 pack)
On Sale 20% off
To get the perfect part every time, you need the right tools. A classic
Rat Tail Comb
can do the trick, as you can use the pick
or the comb itself to get precise parting. This one from Amazon comes in a three-pack for under $5.
For a cheaper option, go with the
Up&up Tail Styling Combs from Target. These come in a two-pack for only $2 (that’s $1 each!). They feature a slightly thicker pick, too, which might benefit those who are typically sensitive to the metal rat tail picks.
When styling fine hair, it’s sometimes not enough to simply blow it out with a round brush. For extra oomph, Santiago says to use “velcro rollers at the top section for 10 minutes,” calling this trick “old-school magic.” If you’re in a hurry, you can use the Kitsch Volumizing Roller Clips on your front top section for added lift around your hairline.
Kitsch Volumizing Roller Clips
The
Kitsch Volumizing Roller Clips are great if you’re in a hurry or want to refresh your front pieces. Plus, they’re super easy to use compared to classic rollers, thanks to their clip design.
Conair Heatless Hair Curlers
On Sale 22% off
We love the OG velcro curlers because they’re cheap and effective. Case in point: The
Conair Heatless Hair Curlers
are under $10, and you get 31 curlers in various sizes per pack.
Finish It Up With a Spritz of Hairspray
Fine hair is likely to fall and not hold style as well as thicker textures, so finishing off your hairstyle with some volumizing hairspray like Sexy Hair Big Spray And Play Hair Spray or Matrix High Amplify Proformance Hair Spray can help you keep everything in place and might even give you a better lift, too.
Sexy Hair Big Spray And Play Hair Spray
On Sale 9% off
Give your hairstyle the finish it deserves with the
Sexy Hair Big Spray And Play Hair Spray. This hairspray is designed to give strands a flexible hold while also lifting and volumizing, creating the illusion of more body.
Matrix High Amplify Proforma Hair Spray
The
Matrix High Amplify Proforma Hair Spray is another one of the best volumizing hair sprays. This one boasts a texturizing finish with a firmer hold. It can also help lift the roots and, more importantly, keep them lifted.
