Frequently Asked Questions
The first effects — stronger hair, less shedding when washing — are generally felt within the first 4 to 6 weeks.
Visible hair growth requires a full 90-day treatment. Hair grows on average one centimeter per month: patience is part of the protocol.
Yes. The kit was designed for all hair types, including fine and thin hair. Our active ingredients work directly on the scalp to stimulate follicles — the texture of existing hair is not a factor.
Our kit works effectively on hair loss related to stress, nutritional deficiencies, hormonal changes, or inadequate hair care routines. In case of diagnosed alopecia, we recommend consulting a dermatologist before starting the treatment.
Yes, the topical products work independently. For optimal results in 90 days, the complete kit is recommended.
No. Our gummies are formulated with vitamins, minerals, and active ingredients specifically targeted for hair health — without hormones, without excess added sugars.
Apply the mask to wet hair, before or after shampooing according to your preference. Leave on for 5 to 10 minutes, then rinse thoroughly.
2 to 3 times per week is the ideal frequency for most hair types.
Yes, absolutely. Our products are compatible with colored, bleached, and blonde hair.
Yuka doesn't account for dosages. The active ingredients that lower the rating are precisely those that ensure the product's effectiveness, dosed intentionally.
It's a deliberate choice. Sulfate deeply cleanses the scalp, which is the foundation for a protocol focused on hair stimulation.
Silicone protects the hair fiber and limits mechanical breakage. When used at the appropriate dose and properly rinsed, it does not accumulate.

My hair wasn't in great shape and I came across your site on TikTok. I was a little hesitant given the price, but honestly I don't regret it at all. My hair has completely transformed in just one month.

★★★★★
Hair is shiny, breaks less and feels super soft.

In just 1 month of use I've already gained 4-5cm of length and the products aren't even a third empty yet. The scent is incredible and my hair is visibly thicker. I'm so happy I found Vinci!
Laboratoires Vinci
We are thrilled to read your review! Seeing such progress in the first month is incredible — just imagine what the full 90 days will bring. Thank you for sharing!
★★★★★
I started using this line last year and it's truly incredible. Everyone keeps asking me what I've been doing to make my hair grow so fast. It promotes growth but also leaves hair so soft and shiny. I swear by this brand now. Thank you Laboratoires Vinci!
Laboratoires Vinci

★★★★★
I love it — I'm getting my hair back.
★★★★★
Amazing products! From the very first use I felt a difference. The shampoo lathers beautifully. The mask has a unique silky, elastic texture and leaves hair light, soft and smooth without weighing it down. No change to my scalp oil balance. The serum doesn't make roots greasy either. Subtle, pleasant scent. I'll definitely be ordering again.
★★★★★
Very, very good products.
★★★★★
For a first month I'm very satisfied — my hair is slowly coming back to life. Thank you so much!

I loved it. Once the routine was complete, I had recovered the softness, length and thickness I was missing. Really noticeable results — I recommend!
Laboratoires Vinci

Thank you so much for your message! We're thrilled you're seeing more volume and growth — that's exactly what the routine is designed to deliver. Enjoy!
★★★★★
It's been a month since I started and I've seen real growth. I even got a trim in between and I'm already back to where I was — and beyond. I'm genuinely amazed. I'll definitely reorder.
Laboratoires Vinci
Thank you so much for your message Sonia! We're so glad you're already seeing real growth after just one month. The fact that you grew back after a trim is the best proof the routine is working!
★★★★★
Very happy with my purchase — every product is wonderful!
Laboratoires Vinci
Hi Viktoria, we are so glad to hear that you are very satisfied with the products. Thank you!
★★★★★
My hair has gained so much density and has grown. It's soft and silky. I've been using the line for 9 months now and I won't stop — I can really see the difference, and so can everyone around me.
Laboratoires Vinci
Thank you so much for your message Salima! Nine months of loyalty is the most beautiful review we could ever receive. We're so glad the results speak for themselves — for you and everyone around you!
★★★★★
I've noticed a difference in the length of my hair — I've been using the shampoo, mask and gummies for a month. Still waiting for more thickness but I'm happy overall.
Laboratoires Vinci
Thank you so much for your message Pauline! We're glad you're already noticing more length after just one month. Thickness usually follows — keep going for the full 90 days!
★★★★★
I've just started the routine and I was more than pleasantly surprised by the scent — the products smell absolutely amazing. And the results after my very first wash were already impressive. I also want to mention the customer service which is very responsive and goes above and beyond.
Laboratoires Vinci
Thank you so much for your message! We're so happy your first impressions have been so positive — both with the products and our team. We can't wait for you to see the full results!
★★★★★
Very satisfied. I've been using it 3 times a week for a month. I've gained volume and my hair is luminous, soft and easier to style. I recommend it to everyone.
Laboratoires Vinci
It's a pleasure to read your review Susana! We're thrilled the routine is delivering such visible results — more volume, shine and softness. Thank you for recommending us!
★★★★★
Happy with my purchase.
Laboratoires Vinci
Hello Emilie, we're so glad your purchase is bringing you satisfaction. Don't hesitate to reach out if you have any questions about your routine!
★★★★★
There was a slight delay on my order so I received a little gift as compensation — a lovely touch! Since using the products I can see my hair growing and, more importantly, it no longer looks damaged the way it used to. Thrilled!
★★★★★
Thank you for my order! The products arrived in great condition. It's only been a month but the results are already there — my hair has gained so much density and grown noticeably. I'm really happy and I fully recommend this brand.
★★★★★
Very good pack — my hair has regained strength and shine. In the first month I feel like it's already grown slightly. Fast delivery. I recommend!
★★★★★
I naturally recovered my volume and also noticed real growth. I'm so happy with this brand and I'll definitely reorder.
★★★★★
Best routine ever — it's the only one that has actually given me visible results.
★★★★★
It's great — my hair has already grown!
★★★★★
I love it! Obvious results after just 10 days. I'm going to reorder. Hoping for the third white bottle!
★★★★★
I received a package with a damaged mask — part of it had spilled. I filed a complaint and Vinci was super reactive, reshipping immediately. The products are great and the customer service is excellent.
Laboratoires Vinci
Thank you for your message Sonia — we're happy we were able to resolve the issue quickly. Enjoy the rest of your routine!
★★★★★
The texture of my naturally porous hair has completely changed. I've been getting so many compliments on how shiny my hair is. My curls are more defined and hydrated. I'm genuinely impressed and will definitely keep reordering.
★★★★★
I've been using the products for two weeks now — great results so far. And I just received the serum drops which I tried tonight for the first time.
★★★★★
As a hairdresser, I test a lot of hair products — and honestly, it's rare that I have nothing negative to say. But this time, I'm genuinely blown away. I started the routine one month ago and within the first weeks I already saw a real difference: my hair visibly grew, it's stronger, denser, and healthier overall. I'm so happy with this brand — both as a professional and as a customer. This is exactly the kind of product I'd recommend with complete confidence.
★★★★★
Your routine is literally saving my hair. I had completely burned it from bleaching, so I shaved it and started fresh with Vinci. After 4 months my hair is back, healthy, and growing fast. I'm never switching brands.
★★★★★
I've already ordered three 3-month kits — I'm on my 10th month and I love it. Fast service, incredible quality, no shedding and real growth. I'll never switch brands. Highly recommend!
★★★★★
It was a little gift for my wife and apparently she loves it — she's already seeing early results, which is great. She uses the full routine and I'm glad to see it's working!
★★★★★
Perfect — fast shipping and the product's effectiveness is already noticeable after one month. Significant reduction in hair loss and real growth. I recommend it 100%!
★★★★★
Very happy with my Vinci routine. I got the 3-month kit to try it out and I was not expecting results this fast. After just one month I already see a real difference in terms of growth and hair health. I recommend without hesitation.
★★★★★
It's been 30 days since I started the routine. I love the scent and the gummies taste great. My hair is already getting healthier and shinier. As for growth, it's still early but I have so many baby hairs coming in — a great sign! I also received a hair serum as a gift, which was a lovely touch.
★★★★★
I've been using Vinci products for over a year and I'm obsessed. I genuinely can't see myself switching to anything else. I plan my orders in advance so I never run out — and the one time I had to use another brand while waiting for delivery, I was genuinely disappointed. These products are irreplaceable.
★★★★★
Incredible, nothing to say — it does make hair a little dry but I received the old version before the reformulation, so I haven't tested the new one yet. Curious to compare!
★★★★★
I've only been using it for two weeks — I like it a lot, nothing to complain about. Great so far!
★★★★★
Quality products — my hair no longer sheds and the regrowth is noticeable. I recommend.
★★★★★
After one month of use I'm obsessed with the shampoo and mask. I love their textures — incredibly effective, and my hair is already visibly healthier and shinier.
★★★★★
As always — top quality products.
★★★★★
For growth I haven't noticed a big difference yet, but for shedding and thickness, the change is real and significant. Very satisfied overall.
★★★★★
I'm genuinely shocked — it's been exactly one month and I've already gained about 5cm. I can see new baby hairs at my roots. I'm absolutely amazed. I won't switch to anything else.
★★★★★
Excellent! Everything I needed for my fragile, fine hair. The routine is easy to follow and the results are there. Highly recommend.
★★★★★
After seeing it all over TikTok I finally caved and ordered. Almost one month in and I'm so happy. I've been able to wash my hair less often, it's softer, shinier and feels alive again. Just waiting to see the full growth at the end of 3 months — but I'm already totally convinced. Go for it!
★★★★★
My hair has changed so much since I started using your line. More volume, more shine and real growth. I'm very happy and grateful. Thank you.
★★★★★
Wait and see — I've already noticed some thickness after 3 days but no length yet, which is normal since I just started. Ask me again in 30 days for a proper verdict.
Laboratoires Vinci
Hello, thank you for your message and for your trust! After just a few days, it's completely normal not to see length results yet. Hair grows an average of 1cm per month, so the routine needs the full 90 days to show its true potential. The thickness you're already noticing is a great early sign — we'd love to hear your update at the end of the routine!
★★★★★
No improvement at all. I'm still losing my hair and it's not growing. I'm really disappointed.
Laboratoires Vinci
Hello Naoual, we are truly sorry to hear that the routine didn't deliver the results you hoped for. Following our conversations, we have processed a full refund as part of our satisfaction guarantee. We remain committed to supporting you and hope you'll give us another opportunity in the future.
★★★★★
Can't wait to see the results at the end of the routine!
★★★★★
The products didn't work on my hair personally. That said, the customer service is excellent — the team is very professional, attentive and incredibly responsive. Fast delivery, replies within 24 hours and an immediate refund. So I'm giving 3 stars: the product wasn't right for me, but the service was impeccable.
★★★★★
I love your products — I've been using them for years. But unfortunately my last delivery arrived with all the bottles open and more than half the contents lost. The products genuinely work — it's just the shipping that let me down.
Laboratoires Vinci
Hello, thank you for your loyalty and for sharing this. We are truly sorry about this delivery incident — this is absolutely not the experience we want for our customers. We have reshipped your complete order at no cost and reinforced our packaging to prevent this from happening again. We hope this won't discourage you from continuing the routine!
★★★★★
I never received my order. Very disappointed.
Laboratoires Vinci
Hello Serena, thank you for sharing your experience. After checking, your first package was returned to our warehouse after a failed delivery attempt. We immediately reshipped a new package at no cost. We're sorry for the inconvenience and hope you'll enjoy the products!
★★★★★
No results at all. I've been trying for almost 2 weeks and I don't see any change yet.
Laboratoires Vinci
Hello Laura, thank you for your feedback and your trust. Please be reassured — it is completely normal not to see visible results after just 2 weeks. Hair growth is a slow biological process, and our routine is designed as a 90-day protocol. We'd love to hear from you at the end of the routine and we're confident you'll see a real difference. Don't hesitate to reach out!
★★★★★
A lovely discovery — an incredible softness I rarely experience. I feel like I've regained some thickness. I'll wait until the end of the 3 months to assess the growth. For now I'm satisfied with the results.
★★★★★
My hair has almost completely stopped shedding. It's grown at least 4cm in just a few weeks of use. I'm very satisfied with the shampoo and conditioner.
★★★★★
I have polycystic ovary syndrome and I used the Growth & Shine Kit to help restore my natural hair. I haven't seen the results yet, but it's a good product overall. The only downside for me is that the line makes my hair oily — after 2 to 3 days it already feels greasy. I think I'll continue the routine but alternate with another product.
★★★★★
Hair is softer and slightly shinier, but no growth results yet — though I can't wait to see the effects over time. The scent is incredible though, I absolutely love it.
Laboratoires Vinci
Hello Emilie, thank you for your review! We can't wait to hear about your growth progress too. Have a wonderful day!
★★★★★
Disappointed by the kit — there is sodium in the shampoo and silicone in the mask. In both products the garlic is very far down the ingredient list, which means there's very little of it. I expected a more natural formula.
Laboratoires Vinci
Hello Julie, thank you for your comment. We understand your concern about the ingredients. Our formula uses surfactants at a specific concentration for deep scalp cleansing — essential for a growth-focused routine. As for the silicone, it protects the hair fiber and prevents breakage. Ingredient lists are ordered by quantity, but it's the active concentration that matters, not its position on the list. We're sorry the formula wasn't the right fit and remain available to discuss further.
