My Journey With Biolage Full Density Shampoo

I’ll be honest—my hair has been a source of frustration for years.
It’s fine, prone to falling flat, and lately, I’ve noticed it thinning, especially after a stressful year.
I’d tried countless volumizing shampoos, but they either left my hair feeling stripped or weighed it down with residue.
Then I stumbled across Biolage Full Density Shampoo, and let me tell you, it’s been a revelation.
The first time I used it, I was hooked on the scent—a clean, fresh aroma that’s subtle but lingers all day.
It’s not overpowering like some fruity or floral shampoos, which I appreciate. The formula is thick and creamy, and a small dollop goes a long way.
As I massaged it into my wet hair, it lathered up beautifully, making my scalp feel squeaky clean without that tight, dry sensation. Rinsing it out, I could already sense a difference—my hair felt lighter, almost buoyant.
After blow-drying, the real magic happened. My usually limp strands had noticeable volume, especially at the roots. It wasn’t just a superficial fluff either; my hair felt thicker and more resilient. I ran my fingers through it, and it was soft, shiny, and—dare I say—fuller.
Over the next few weeks, I used it three times a week, pairing it with the Full Density Conditioner as recommended. The results kept getting better. My hair didn’t get greasy as quickly, and I even noticed less hair fall in the shower, which was a huge relief given my recent thinning concerns.
What stood out most was how it didn’t fade my color-treated hair. I dye my hair a warm brown, and other shampoos often dull it after a few washes. Not this one—it kept my color vibrant while adding that coveted density.
Sure, it’s a bit pricier than drugstore brands, but the bottle lasts ages since you don’t need much per wash. For me, the confidence of having fuller-looking hair is worth every penny.
Pros of Biolage Full Density Shampoo

- Boosts Volume Instantly: From the first wash, this shampoo delivers on its promise of fuller hair. The biotin and zinc PCA work together to lift your roots and give your strands a thicker appearance. I noticed my hair looked bouncier right after drying, and the volume held up even on humid days. It’s like a salon blowout without the hassle.
- Strengthens and Reduces Hair Fall: Thinning hair is a nightmare, but this shampoo helps fortify your strands. After a month of use, I saw less hair in my brush and drain, which was a huge win. The formula removes follicle-clogging impurities, letting your scalp breathe and supporting healthier hair growth over time.
- Gentle on Color-Treated Hair: If you dye your hair, you’ll love that this shampoo is color-safe. It doesn’t strip or fade your hue, which is a common issue with volumizing shampoos. My brown locks stayed rich and glossy, and I didn’t need to rush back to the salon for a touch-up.
- Vegan and Cruelty-Free Formula: I’m all about clean beauty, and Biolage checks those boxes. It’s free of parabens, silicones, mineral oils, and artificial colors, plus it’s vegan and cruelty-free. Knowing I’m using an ethical product makes me feel good about my purchase.
- Pleasant, Long-Lasting Scent: The fragrance is a standout—clean, fresh, and just the right amount of sophisticated. It lingers in your hair all day without being overwhelming. I’ve gotten compliments on how great my hair smells, which is always a mood-lifter.
- Economical Usage: A little goes a long way with this shampoo. The thick, creamy texture means you only need a small amount to get a rich lather. My 250ml bottle has lasted over two months with regular use, making the price feel more justified.
Not-So-Good Parts of Biolage Full Density Shampoo
- Higher Price Point: Let’s talk about the elephant in the room: the cost. At around $24 for a 250ml bottle, it’s not the cheapest option out there. If you’re used to grabbing a $5 shampoo from the drugstore, the sticker shock might hit hard. That said, the quality and longevity make it a worthwhile investment for me, but it could be a stretch for budget-conscious folks.
- Can Feel Slightly Drying Without Conditioner: While the shampoo cleanses beautifully, it can leave your hair feeling a tad dry if you skip the conditioner. My ends felt a bit parched the first time I used it alone, so I’d recommend pairing it with the Full Density Conditioner or a hydrating mask to keep things balanced.
- Initial Volume Fades Slightly: The instant volumizing effect is amazing, but I noticed that the “full” feeling sometimes diminishes after rinsing. It still adds density over time, but don’t expect a permanent, dramatic boost from day one. Patience is key for long-term results.
- Not a Miracle for Severe Thinning: If you’re dealing with significant hair loss, this shampoo helps but isn’t a cure-all. It strengthens and adds density, but it won’t regrow hair or fix underlying issues like hormonal imbalances. For that, you might need to consult a dermatologist alongside using this product.
Tips For Using Biolage Full Density Shampoo
- Use It Correctly for Best Results: To get the most out of this shampoo, apply it to wet hair and massage it into your scalp with gentle, circular motions. Focus on the roots to lift impurities and boost volume. Let it sit for a minute before rinsing thoroughly. I’ve found that repeating the wash once a week helps keep my scalp extra clean.
- Pair with the Full Density System: For maximum impact, use the Full Density Conditioner and Densifying Spray Treatment. The conditioner hydrates without weighing your hair down, while the spray adds extra thickness. I apply the spray to damp hair before blow-drying, and it makes a noticeable difference in fullness.
- Wash 2-3 Times a Week: You don’t need to use this shampoo daily. I wash my hair three times a week to avoid over-cleansing, which can strip natural oils. On off days, I use a dry shampoo to keep things fresh. This routine helps maintain volume and prevents my scalp from getting too dry.
- Protect Your Hair from Heat: Heat styling can weaken thin hair, so always use a heat protectant before blow-drying or curling. I spritz Biolage’s Thermal Active Spray on damp hair for added protection. Also, try air-drying when possible to minimize damage and preserve your hair’s strength.
- Support Your Scalp Health: A healthy scalp is crucial for thicker hair. Exfoliate your scalp once a month with a gentle scrub to remove buildup. I also massage my scalp with my fingertips while shampooing to stimulate blood flow, which can encourage growth over time.
- Stay Consistent for Long-Term Benefits: This shampoo isn’t a quick fix—it’s a long-term investment. Use it consistently for at least a month to see fuller, stronger hair. I noticed subtle improvements after two weeks, but the real difference kicked in around week four. Stick with it, and you’ll thank yourself later.
Comparison with Other Brands
Let’s pit Biolage Full Density Shampoo against three popular competitors: Nioxin System 3 Scalp Care + Hair Thickening Leave-In Treatment, Redken Volume Injection Shampoo, and OGX Thick & Full Biotin Shampoo.
I’ve tested them all, so here’s how they measure up head-to-head.
- Biolage Vs. Nioxin System 3 Scalp Care + Hair Thickening Leave-In Treatment

Nioxin System 3 is a powerhouse for scalp health, designed for thinning hair with a shampoo, conditioner, and leave-in treatment trio.
Its pepperminty formula left my scalp tingling and refreshed, and after a month, I noticed less hair fall, similar to Biolage.
However, Nioxin’s volume boost wasn’t as instant—my hair felt clean but not as full at the roots.
Biolage’s creamy lather and immediate lift gave me a salon-fresh look right away, while Nioxin felt more clinical, like a treatment plan.
Nioxin’s multi-step system is thorough but time-consuming, and at around $50 for the kit, it’s pricier than Biolage’s $24 shampoo alone. If scalp therapy is your priority, Nioxin’s great, but for quick fullness and a luxurious feel, Biolage wins.
- Biolage Vs. Redken Volume Injection Shampoo

Redken Volume Injection Shampoo promises big, bold hair, and it delivers decent lift, especially at the crown.
Its lightweight formula gave my strands a bouncy feel, but the volume faded by day two, and my roots got oily faster than with Biolage.
Redken’s scent is strong and salon-esque, which some love, but I found Biolage’s subtle fragrance more wearable.
Both are color-safe, but Redken felt heavier on my fine hair, almost like it coated my strands.
Priced at about $20, Redken’s a bit cheaper, but Biolage’s longer-lasting freshness and density-building power make it my pick for thin hair.
- Biolage Vs. OGX Thick & Full Biotin Shampoo

OGX Thick & Full Biotin Shampoo is the budget-friendly contender, often under $10 at drugstores.
Its biotin and collagen combo added some thickness, but the effect was fleeting—my hair felt fuller for a few hours but flattened out by evening.
The sweet, almost candy-like scent was overpowering compared to Biolage’s clean aroma.
OGX left my hair feeling slightly coated, not fortified, and didn’t reduce hair fall like Biolage did.
While OGX is wallet-friendly, Biolage’s vegan, cruelty-free formula and lasting results justify the higher price. For serious thinning concerns, Biolage outperforms OGX hands-down.
Why Biolage Stands Out?
Biolage Full Density Shampoo strikes a unique balance: it’s luxurious yet effective, delivering instant volume and long-term strength. Nioxin excels at scalp care but lacks the immediate wow factor, Redken’s volume doesn’t last, and OGX feels like a temporary fix.
Biolage’s clean ingredients, ethical credentials, and ability to keep my hair fresh and full for days make it the clear winner for me.
