Excellent product! My nails were quite soft and damaged for at least 2 years, I tried various products but there was no improvement. With this specific product, I saw improvement from the first week and in 15 days my nails were so hard that they didn't need anything else. The bottle is small but the product is very fluid and needs very little at the free edge. In the end, it is economical. I would buy it again.

On weak nails from acrylic, it strengthens and makes them grow faster. I have them unpolished for 2 months, but it is the only thing that makes them healthier. It is worth every penny and more!

Excellent product! My nails were in very bad condition due to continuous application of acrylic, and with frequent use of this product, I applied it almost every day for a month, I now have strong and long nails, which I never had naturally, they always used to break. And as for the quantity, it lasts a long time, it hasn't even dropped halfway for me even though I've been using it for a long time, so the price is clearly worth it!

My nails peel, break, and generally have a hard time recovering after using semi-permanent polish. After repeated use, they managed to recover after 2 weeks. I highly recommend it

I made the mistake of removing the acrygel I had on my own. In order to remove the product without a drill, I had to file it, so I had to take a nail with it. My nail obviously became very thin like a flake, it would break with the slightest touch. The recommended dosage is three times a week at the edge of the nail, but I applied it twice a day all over the length. In 2 months, it did a pretty good job (compared to how I ruined it), it had slightly hardened the nail, nothing amazing though. The liquid should not touch the skin and cuticles because it hardens them too much, and you also have to "wipe off" the excess liquid from the brush because it spreads too much and "spills" from the nail. As long as I used the liquid, I didn't let my nails grow too long because they would break and the filing would shorten them. In the end, I stopped using it because I rebuilt my nails.

Conclusion: it is expensive but it does the job with intensive use, so I recommend it

Excellent product! I had a huge issue with my nails because they were peeling. I tried many nail polishes from big brands, but they didn't help at all. However, this specific one works wonders from the first two weeks of use! I highly recommend it! It may seem more expensive than others, but it truly heals and lasts a long time.

I use the product daily for 1.5 months. A few hours after use, my nails are hard, but the next day they are soft again. I have managed to grow my nails a little, but they continue to peel and break. It is minimally effective.

After removing my semi-permanent nails, they were destroyed. They became very thin, weak, and peeled off. After 15 days of use (3 times a week), I see a big difference!! It goes without saying that I recommend the product for similar cases.

The best product for nail hardening. My nails are always thin like flakes due to gel polish. However, whenever I decide to remove it to harden my nails, I use this once a day for a month and my nails become unrecognizable, very strong! I have also tried the equivalent from Peggy Sage, which is renowned, but honestly, I wasted my money. It may be expensive, but it's worth it.

Every week a pass and it really has an effect even on thin nails that peel. Very little quantity, but it lasts for over six months because it is not thick like the manicures. I have been using it for years!

After TWO months of treatment, I believe that it has done NOTHING. A slight hardening on my nails... nothing more. The peeling remains NORMAL. It's a shame that I read the comments and fell for it

Very good product, my work really damages my nails, since I started using it I finally managed to make them grow long!!!! They haven't even broken after a strong hit. The instructions say up to 3 times a week but I use it daily

My nails have always been brittle and peeling, so soft that I have broken a nail with a book page. It helped me incredibly to the point that I couldn't believe it from the first application. I continue to use it daily because the condition is severe. Try it without a second thought.

I have been using it for 3 months. I had nails damaged from techniques. Nails that were just starting to grow, the free edge would peel off. This product helped me to be able to grow my natural nails. I highly recommend it.

I haven't been using it for long, but I have already seen a difference...
Personally, I use it more times per week (compared to the instructions for use)...
I am satisfied with the product...
It hasn't presented any problems for me...
I recommend it to those who have weak nails...

The product is self-contradictory. It promises strong nails in the packaging and the instructions recommend applying only on the tips and not on the skin. Where am I supposed to find the tips on nails that are breaking?
