Mavala Scientifique Original Nail Hardener | Strengthens Nails, Hardens Nail Tips, Stops Breakage | 0.16 oz

It took me a year of using this consistently along with the oil, but a nail that was damaged to the point of only being half as long as it should be is finally back to looking as close to normal and as strong as it could be. I’ve been consistent with other products but I believe this is the one that made a lasting/strengthening impression on my brittle, ridged, and damaged nails.

As a lifelong nail chewer, I have never taken care of my hands and nails. Last year, I decided that it was time to grow them out. For a year, I would grow nails to just a hair past the nail bed and they would bend, peel or tear. Every. Single. Time. Even taking biotin didn't help with the level of hardness of my nails, they just grew faster so they could bend or tear quicker. I took a chance with Mavala Scientifique (after reading directions carefully and watching a couple of Youtube videos about how to apply it) and now, three weeks later, I finally have all ten nails at or past the ends of my fingertips without a single tear or peeling nail in that time. This is the first time in my 56 years that I have beautiful, strong, hard nails. I don't recognize my own hands. A word of caution: FOLLOW THE INSTRUCTIONS! Do not get this stuff on your skin, cuticles, etc. because it will harden that area almost instantly. Do not overuse the product, either in volume or frequency. If you over apply in volume, the product can soak past your nails and into your nail bed and it will harden (you really don't want this to happen). If you use it more than twice a week, you will make your nails too hard and they have a real potential to shatter or snap right off. I have used this very sparingly twice a week and every time, I can feel the results immediately-- even the first time I applied it. Over these three weeks, my nails are at just about the perfect hardness and once my two damaged nails are done growing out, I will cut back to once a week, then once a month.This product is expensive, but you really need to use almost none of it and it will last for many years if you're using it properly. Most importantly: IT WORKS. If you struggle with soft, weak nails, Mavala Scientifique is an absolute miracle.

I am absolutely shocked. I have had thin, bendy, peeling nails my whole life (never a nail biter). Just thought it was my genetic lottery. I have tried EVERYTHING (I was a cosmetologist for 10 years and have no idea how I didn’t hear about this). Biotin, collagen, iron, pre-natal vitamins. Nail envy, nail tek, every brands strengtheners and hardeners from drugstore to high end. Nothing worked until now. My nails would bend as soon as they got finger tip length and peel or crack. I am only 3 applications in to this product and my nails feel like acrylic! It’s astounding honestly. I can definitely feel that it’s drying out my nails so I can see how it would be easy to over do it. I have managed to balance this out with consistent application of cuticle oil every time I wash my hands. I have one more application this week, then I will most likely back off to once every week or two and see if they can continue to grow. I am so thoroughly thrilled with this product.

A pesar de su pequeña concentración es un producto muy bueno, ayudo a mi esposa mucho. Lo recomiendo

OK, my nails are always soft and they can split, which is painful after using this product that has completely changed. My fingernails are now extremely strong.I am writing this review after using this for more than six years and during that time I have learned that the best way for me to apply it is approximately every 7 to 10 days just at the tips of my nailsIf you use the product too frequently, then your nails can become brittle, however, starts slowly and you will figure out how much to use quickly.They can be a little bit of pain when you put it on and it soaks into the nail that quickly dissipates, and the results are absolutely worth it. I’ve never seen anything that is this effective at strengthening nails.

Think twice before you buy this product because it’s non refundable and very expensive for 0.16 ounces that will make your nails worse.I wanted to grow out my nails after spending hundreds at the nail salon. I was tired of the upkeep and the UV exposure. In the past I have tried everything, over the counter nail strengtheners, biotin pills, you name it so when I saw this product and the glowing reviews I was excited for something that would work.For two weeks I religiously applied it to the tips of my nails making sure not to have contact with cuticles. The reviews that say it burns/hurts are not lying. Every single time I put this on my nails they throbbed in pain for a good 30 min. I’m a woman and no stranger to pain for beauty but this product did nothing for me except worsen my nails. This product contains Formaldehyde which literally eats away layers of your nail. I had weak nails which bent to the touch but after this product I now have slits were the nail snags on everything and rips off.The pictures don’t lie. The thumb picture is the worst one, the brown on the edge is dried blood where it ate away my nail. Use this product at your own risk.
