How To Get Thicker, Fuller Hair At Any Age

March 19, 2025 by Brooke Hardington

 

It’s been one of those weeks where I’ve noticed way more of my hair in the drain, on my brush, and tangled up in my hair straightener. This morning, I even went to clean the Roomba and saw a ton of long strands caught in the cleaning brushes!

Everything from diet, to hormonal changes, to too-tight hairstyles can weaken hair follicles. And while I know that shedding is natural, it still freaks me out. If you’re anything like me, you’re always on the lookout for ways to add volume and strengthen your strands. Happily, there are tons of haircare products that do just that—and the editors at SheFinds have vetted a bunch of them (so you don’t have to).

Thickening Shampoos & Conditioners

I love a good hair thickening duo, even if I’m not shedding a ton.

That’s because the best thickening shampoos & conditioners plump your strands to give you a full, voluminous mane. They work in tandem to cleanse the scalp of buildup (which could be why your hair’s falling flat) and give you extra oomph. When it comes to thickening products, these are some of our favorites.

Bumble & Bumble Thickening Volume Shampoo ($37)

I’m a sucker for the Bumble & Bumble brand, which I used religiously as a teenager. But it’s not just me—people are obsessed with this softening, hydrating, and non-stripping Thickening Volume Shampoo. Suitable for all hair types, it works to amplify hair for instant volume, all while preventing breakage and adding shine.

Bumble & Bumble Thickening Volume Conditioner ($38)

When used together with Bumble & Bumble’s Thickening Volume Shampoo, the Thickening Volume Conditioner gives you visibly thicker hair, with 2X shine and 2X less breakage (compared to unwashed hair). Formulated with Panthenol and good-for-you hydrators like Safflower Seed Oils, it hydrates hair without leaving behind any residue.

Kérastase Densifique Bodifying Shampoo ($42.60)

Another iconic name in hair is Kérastase, known for its high-performing products and scientific approach to haircare. The brand’s Densifique line is all about addressing the root causes of weakened hair; more specifically, their Densifique Bodifying Shampoo is supercharged with a potent blend of hyaluronic acid, peptides, ceramides, and citric acid to give you thicker, stronger hair, with less breakage. 

Living Proof Perfect Hair Day Shampoo ($17)

This affordable shampoo does a fantastic job of removing dirt, sweat, and product buildup for a squeaky-clean scalp that gives your roots more lift. It’s proven to add 68% more shine, leaving your strands 3X stronger with just one wash (versus untreated hair). All that and it doesn’t strip or over-dry your hair. Yes, please!

Living Proof Perfect Hair Day Conditioner ($17)

The Living Proof Conditioner works alongside the shampoo to give your hair some extra oomph and a lift that lasts. While the shampoo tackles the scalp, this conditioner reduces frizz and flyaways. It also strengthens and detangles for effortless no-snag strands. As a curly-haired girl, I can attest that it makes my hair way more manageable.

Scalp Treatments for Hair Growth & Density

Thick, voluminous hair is tied to healthy hair. And because volume starts at the roots, a scalp treatment can work wonders in thickening your hair. Many scalp treatments will maintain hair health by safeguarding the scalp, promoting blood flow, and delivering nutrients to the hair follicles. They might not sound as “sexy” as a volumizing texture spray or thickening shampoo, but don’t sleep on these scalp treatments!

The Ordinary Multi-Peptide Serum for Hair Density ($15)

I’m obsessed with The Ordinary, and not at all embarrassed to tell you that the top drawer in my bathroom is packed with skincare and haircare products from the brand. Knowing that The Ordinary specializes in affordable, clinically-proven products that are grounded in science, I went ahead and bought their Multi-Peptide Serum for Hair Density for myself about a year ago. It’s a lightweight, leave-in formula that I applied a few times weekly to damp, clean hair. Over time I found that my hair was visibly thicker at the scalp—I guess those peptides and plant-based extracts really worked!

Rogaine Women’s 5% Minoxidil Foam ($50.99)

Rogaine has been the #1 dermatologist recommended and #1 selling hair regrowth brand for over 30 years. Clinically proven to regrow hair that is nearly 50% thicker, this Minoxidil Foam creates an optimal scalp environment that prevents dryness and irritation. It’s formulated with botanical extracts, humectants, and alpha hydroxy acid (AHA) to exfoliate skin and keep your hair follicles open for maximum minoxidil absorption.

Volumizing Styling Products

Whether you have fine hair, thick hair, or a combination of the two, volumizing sprays are like magic in a bottle. Not only can they revive days-old dry hair, they also instantly add dimension and texture to your hair. Whether you want beach-y hair or amped-up volume, we gotcha covered.

Oribe Maximista Thickening Spray ($39.99)

The Oribe Maximista Thickening Spray is differentiated by its good-for-you ingredients, like thickening copolymers for volume and amino acids for strengthening. It also acts as a heat protectant, simultaneously adding volume and density to your roots. Pro tip: Spritz it on damp hair for a little bit of extra lift before you start blow-drying!
