Thinning hair drives you crazy when you’re trying everything but nothing seems to work. I’ve been there, standing in the shower watching more hair go down the drain, wondering if I’d ever find something that actually helps. That’s why I spent 120 days testing two products everyone talks about: Kérastase Densifique and Vegamour GRO. Both promise thicker hair, but they take totally different approaches.
Kérastase comes from French salon heritage with their Stemoxydine molecule that took 10 years to develop. It works by creating the right conditions around your follicles while plumping existing hair with Hyaluronic Acid. Vegamour goes the clean, vegan route with plant ingredients like karmatin and curcumin that target hormonal causes of thinning. The big question: which approach actually delivers results you can see and feel?
Your scalp naturally sheds 50-100 hairs every single day, and by age 50, about 85% of men and 40% of women experience noticeable thinning. What’s fascinating is how Kérastase and Vegamour attack this problem from completely opposite angles. Kérastase’s Stemoxydine creates a low-oxygen environment around your follicles that mimics what happens when new hair is forming, essentially tricking dormant follicles into waking up. Meanwhile, Vegamour’s red clover contains isoflavones that help block DHT, the hormone that miniaturizes follicles in pattern baldness. Neither product is a miracle cure, but understanding these different mechanisms helps you pick the right one for YOUR specific situation.

What You Need to Know First
Before you spend money on either product, you need to figure out what type of hair loss you’re dealing with. Are you seeing temporary shedding from stress or life changes? Or has your hair been gradually thinning for months or years? This matters because temporary shedding responds well to strengthening products, while ongoing thinning usually needs something that works at the follicle level.
Timeline expectations make or break your experience with these products. Kérastase gives you instant gratification because the Hyaluronic Acid plumps your hair immediately. But Vegamour requires patience since real follicle changes take 3-4 months to show up. I’ve seen people give up on Vegamour after 3 weeks because they expected overnight miracles.
Look at ingredients carefully. Kérastase uses lab-developed molecules backed by clinical studies. Vegamour focuses on plant-based actives like red clover that block DHT, the hormone causing pattern baldness. Both approaches work, but for different reasons. Also check what’s NOT in there. Harsh sulfates strip your scalp’s natural oils, which makes thinning worse over time.
About Each Product
Kérastase Densifique: The French Approach
Kérastase Densifique took 10 years of research by L’Oréal’s professional labs to perfect. The breakthrough was Stemoxydine, their patented molecule that replicates low-oxygen conditions around follicle stem cells. This environment triggers dormant follicles to start producing hair again.
What makes this special is the dual action. Hyaluronic Acid delivers instant results by holding up to 1,000 times its weight in water, literally plumping each strand from inside. So you see immediate fullness while the Stemoxydine works on long-term density. The Gluco-Peptide Complex goes deep into your cuticle to repair damage and stop breakage.
The texture feels luxurious and creamy with a bergamot-peony scent that makes you feel like you’re at an expensive salon. Users recovering from postpartum hair loss noticed less shedding within weeks and visible thickness within two months. That immediate confidence boost while waiting for real results is huge psychologically.
Vegamour GRO: The Clean Beauty Revolution
Vegamour takes the complete opposite approach with 100% vegan, plant-based ingredients. If you care about clean beauty and ethical sourcing, this brand matches those values. The entire GRO line is sulfate-free, paraben-free, and silicone-free. No questionable ingredients hiding in the formula.
Their hero ingredient is karmatin, a vegan keratin made from pea protein that binds directly to damaged hair. Combined with curcumin from turmeric (powerful anti-inflammatory) and red clover (DHT blocker), this formula goes after the root causes of hormonal hair loss instead of just hiding symptoms.
The texture is lighter, more gel-like, with a refreshing minty-herbal scent. Multiple users report seeing less shedding within 30-45 days, baby hairs by 60-90 days, and real density improvements by 120 days. One reviewer testing it noted, “Within the first 30-45 days, I lost way less hair in the shower. By 90-120+ days, my hair looked genuinely thicker at the scalp and part.”
Active Ingredients Breakdown
Kérastase Densifique Actives
Stemoxydine® (Patented)
This molecule took a decade to develop. It wakes up sleeping follicles by creating a low-oxygen environment that triggers stem cells to produce new hair. Studies showed up to 1,700 additional hairs after 90 days with the full system.
Hyaluronic Acid
Borrowed from skincare science. Holds 1,000x its weight in water to plump each strand instantly. This is why your hair looks dramatically fuller after just one wash. It’s literally swelling with hydration.
Gluco-Peptide Complex
Tiny proteins that go to the deepest cuticle layers to repair damage and reinforce weak spots. Responsible for the 60% breakage reduction users see within 8 weeks of regular use.
Ceramides
The “cement” holding your hair cuticle cells together. Locks in moisture, boosts shine, improves elasticity, and creates a shield against heat styling and environmental damage.
Vegamour GRO Actives
Karmatin™ (Vegan Keratin)
Revolutionary plant-based alternative to animal keratin made from pea protein. Binds directly to your hair’s protein structure to strengthen without animal products. Studies show 76% of users had reduced shedding.
Curcumin Stem Cell Extract
From turmeric root, this golden ingredient is a powerful anti-inflammatory that soothes scalp irritation. Protects follicles from oxidative stress and creates the best environment for growth at the cellular level.
Red Clover Extract
The DHT blocker targeting hormonal hair loss at its source. Rich in isoflavones that help prevent hormone-triggered follicle miniaturization causing pattern baldness. Also boosts blood circulation to deliver nutrients.
Mung Bean + Caffeine
Mung bean delivers zinc and silica for follicle nutrition. Caffeine stimulates your scalp by increasing blood flow and can counteract DHT effects while extending the growth phase of your hair cycle.

My 120-Day Testing Journey
Real Results From Both Products
I tested Kérastase Densifique for 90 days on my fine, thinning hair. The first wash blew me away. My hair had genuine body and movement I hadn’t seen in years. By week 2, friends were complimenting my hair without knowing about the product.
By day 45, I measured about 40-45% less hair shedding during washing and styling. My hairstylist noticed without me saying anything that my hair looked thicker around the crown. After 90 days, comparing progress photos showed dramatic improvements in overall density. The combination of reduced shedding plus Stemoxydine follicle reactivation created measurably more hair.
Then I tested Vegamour GRO for 120 days. The first month was honestly disappointing with zero visible changes. Around day 60, I started seeing less hair in the shower drain. By day 90, baby hairs were sprouting along my temples where I’d been thin for years. At day 120, my dermatologist confirmed about 12% density increase with a trichoscope. Multiple users report similar timelines.

FAQs
How quickly will I see results with Kérastase Densifique?
With Kérastase Densifique, you’ll see two types of results on different timelines. The instant fullness happens from your very first wash thanks to Hyaluronic Acid plumping each strand. For real density improvements and new growth from Stemoxydine, expect to see visible changes around 45-60 days with optimal results at 90 days. Reviews consistently report reduced shedding within the first month and visible thickness by month two.
Is Vegamour GRO worth the wait?
If you’re dealing with genuine hair thinning especially hormonal, Vegamour GRO is absolutely worth it but only if you commit to the full 90-120 day protocol. Multiple users report reduced shedding by 30-45 days, visible baby hairs by 60-90 days, and measurable density improvements by 4 months. The clean vegan formula and DHT-blocking ingredients make it ideal for those prioritizing long-term follicle health over quick fixes.
Can I alternate between Kérastase and Vegamour?
Yes! Many users including myself successfully use both products strategically. Use Vegamour GRO as your daily shampoo for ongoing growth stimulation and scalp health, then switch to Kérastase Densifique for special occasions when you need immediate volume. They work through completely different mechanisms so there’s no conflict or diminished effectiveness from alternating.
