Our Top Picks: Editor & Expert Reviews
We recruited beauty editors and experts to test each product over several weeks, considering volume, fullness, hair feel, scalp health, scent, ease of use, and value. Here’s how the favorites performed:
- Christophe Robin Cleansing Volumizing Paste: This standout formula uses Moroccan-lava clay to absorb oil and physically exfoliate with sugar crystals, providing an intensely cleansed scalp and noticeably boosted roots. The texture is a dense paste that foams up after massaging, and while getting a good lather takes effort, the payoff is *major* volume without dryness. It’s ideal for oily/fine to normal hair types.
Editor review: “Adds more volume than any other product I’ve ever tried. Cleans hair really well but doesn’t leave it dry or weighed down.” - Virtue Flourish Shampoo: Packed with strengthening keratin protein, peptides, and red algae extract, this formula was designed for thinning hair and sheds. It cleanses deeply while supplying scalp moisture, which helps keep follicles plump and smooth. Caution: May dry out very curly hair. Reportedly drastically reduces shedding after just a few uses.
- John Frieda ULTRAfiller+ Thickening Shampoo: The Good Housekeeping Beauty Lab-awarded duo (used with its conditioner) made hair easier to style, added fullness right after washing, and didn’t leave any residue. Some testers noted increased frizz as a minor con. “Felt thicker and fuller after the first wash,” a tester shared.
- Davines Volu Shampoo: This shampoo relies on polymers and light hydrators that temporarily coat and swell hair strands, creating a fuller effect that lasts until your next wash. Best for fine hair that looks flat despite other volumizing efforts.
- L’Oréal Paris Elvive Volume Filler: Featuring Filloxane and collagen, this formula lifts roots and offers instant thickness even after heat styling. Affordable and easy to find.
Thickening Shampoo 101: Do They Really Work?
One of the most common questions surrounding thickening shampoos is simple: can these actually make your hair grow thicker? The short answer: not permanently. Shampoo can’t biologically change hair density or follicle size; the thickness of each strand is mostly determined by genetics, hormones, and age. Trichologists and dermatologists agree: “Thickening shampoo can give the illusion of thicker hair,” says trichologist Gretchen Friese. Certain formulas add bulk by coating strands or raising roots with exfoliation or surfactants, making thin hair appear denser until you wash out the ingredients.
- Polymers & Hydrators: Ingredients like hydrolyzed wheat protein, collagen, or Filloxane cling to the hair shaft, temporarily swelling strands.
- Exfoliants: Sugar crystals or clay slough off oil and scalp buildup, instantly lifting roots and preventing flatness.
- Moisturizers & Oils: Tea tree oil, hyaluronic acid, and botanicals contribute to scalp health and promote less breakage.
Why Is My Hair Thinning?
Thinning hair can be caused by multiple factors, and understanding the root is essential for choosing more effective products:
- Genetics & Hormonal Changes: The most common cause is miniaturization, the process of hair strands gradually shrinking and thinning due to genes and fluctuating hormones. Over time, this can lead to visible hair loss.
- Age: As you age, follicles may shrink, yielding finer hair and less density overall.
- Stress & Lifestyle: Physical or psychological stress (moving, job loss, breakup) or underlying medical issues (vitamin deficiency, thyroid, anemia, hormonal imbalances) can trigger telogen effluvium, a temporary form of shedding that reverses once the root cause is addressed.
- Scalp Health: Build-up, chronic dryness, or product residue can weigh hair down, causing limpness and increased shed.

How to Choose the Right Thickening Shampoo for You
Not all thickening shampoos work for every hair type or concern. Here’s how to narrow down your options:
- Assess Hair Type: Is your hair oily, dry, frizzy, color-treated, or curly? Look for shampoos formulated for your unique texture and needs.
- Check for Sulfate-Free: Many top formulas avoid sulfates to prevent stripping the scalp and color, while others use strong cleansers for deep root lift.
- Key Ingredients to Look For:
- Proteins – keratin, wheat, rice, or soy proteins for plumping
- Botanicals – tea tree, sage, bamboo fiber, aloe vera
- Polymers and collagen for instant swelling
- Exfoliating agents for build-up removal
- On a Budget? Affordable options from drugstore brands like OGX, L’Oréal, or Pantene rival pricier salon picks for many users.
- Scalp Sensitivity or Hair Loss? Look for calming ingredients like peptides, hyaluronic acid, tea tree oil, or formulas labeled “safe for thinning hair.” See a dermatologist if hair loss persists.
Frequently Asked Questions (FAQs)
Q: Can thickening shampoo make my hair actually grow thicker?
A: No, thickening shampoos do not change the chemical structure, density, or follicle size of hair. They give a temporary thickened effect by coating strands, lifting roots, or hydrating the scalp to create the illusion of fuller hair.
Q: How long does the thickening effect last?
A: The effect usually lasts until your next wash—ingredients like polymers, proteins, and hydrators rinse out, so hair may go back to its regular look if you skip use.
Q: Is thickening shampoo safe for color-treated hair?
A: Always check the label for color-safe claims and avoid harsh sulfates if your hair is dyed. Many reviewed formulas are sulfate-free and gentle on color.
Q: What ingredients should I avoid if I have a sensitive scalp?
A: If you experience irritation or sensitivity, steer clear of heavy surfactants (often listed as sodium lauryl sulfate), strong perfumes, or alcohols. Look for soothing botanicals like aloe or tea tree, and prioritize “dermatologist-tested” products.
Q: Should I pair thickening shampoo with conditioner or styling products?
A: Yes, for best results, use a lightweight or volume-boosting conditioner and styling sprays for extra fullness. Avoid heavy creams or oils that might counteract volume.
Editor’s Tips for Thicker, Fuller Hair
- Massage roots while shampooing to boost blood flow and help product penetrate. Using a scalp massager enhances lather and root lift.
- Limit heavy styling products that might weigh down hair after washing.
- Load up on texturizing sprays post-wash and blow dry with a round brush for instant volume.
- Spritz lightweight conditioner mid-shaft to ends only, never at the roots.
- If you experience worsening hair loss, see a dermatologist to rule out medical or nutritional causes.
How Experts Test Hair Thickening Products
The Good Housekeeping Institute Beauty Lab and industry experts employ rigorous testing standards for thickening shampoos:
- Microscopic Tests: Human hair swatches are measured for changes in density and diameter using laser micrometer instruments.
- Consumer Feedback: Products distributed in label-masked bottles collect feedback on lather, scent, manageability, and volume.
- Real-World Testing: Editors and stylists assess use over several weeks for consistently visible fullness and scalp health.

Final Thoughts: Building a Thicker Haircare Routine
Whether your hair is fine by nature or thinning from stress, age, or hormones, a well-chosen thickening shampoo can transform how your hair looks and feels—at least until your next wash. Look for formulas that suit your hair type, offer scalp benefits, and complement your conditioner and styling routine. Remember, for medical-level changes in density, always consult your dermatologist. Strong, healthy hair starts with the right foundation of cleansing and volume-boosting care.
