Nail Hardener Kalyon Nail Protective Hardener

I always use it after nail extensions, and it effectively restores and strengthens them.

I am very satisfied. I have been purchasing it not for the first time. It stays on my nails for the entire week. It strengthens well.

An excellent product for strengthening nails. I have used it not for the first time. The first time I used it was to restore my nails after gel polish. It did a great job. I highly recommend it.

I forgot to mention the negatives)))
No wonder it only gets 3 stars from me.

If you apply it on freshly done manicure (dust, cuticle trimming), it stings!!!

There are artificial substances in the composition....

I used it about 10-12 years ago in school. It helped me grow my first long nails back then.

Recently, I decided to purchase it again. I didn't notice any changes in growth or wow-strengthening. However, for those who don't use gel or gel polish, this nail polish is a great alternative.

It is transparent, has a light milky undertone, applies evenly in two coats, and makes the nails look well-groomed. It lasts for 5 days on me.

Excellent product for fragile and brittle nails, it has a matte undertone. I highly recommend it.

I really liked it. I want to buy more, but it's not available for sale. I highly recommend it.

I do not recommend using it within a week and a half after removing gel polish in order to avoid any unpleasant sensations. However, if you wait a bit, this super product will work wonders and give a pleasant color to your nails. It also nourishes and heals them after gel polish application.

I did not buy it here. I have never experienced such a nightmare in all my years of life. Immediately after applying it, my nails and cuticles started to burn horribly. Fine, I can endure it. I endured it until 2 in the morning. Then I removed it with nail polish remover. By morning, my fingers were swollen and my cuticles were inflamed. My fingers were hot and red. The store where I bought this product said it was normal and I should just bear with it. Nonsense! I can only imagine what's in the ingredients. Luckily, I was able to return this cursed gift. I DO NOT RECOMMEND IT! I really hope I can avoid going to the doctor.

I applied the nail polish and after 4-5 minutes, my nails started to burn a lot. I put my hands in cold water and when the pain subsided a bit, I washed it off. The burning sensation was simply unbearable!!!!! Now I'm worried that my nails might just fall off! I'm not allergic! Girls, never ever use this poison!

Two years ago, a friend recommended the "korablik" to me, and I really liked it. The nails indeed become stronger, and using it as a clear polish looks great - the nails look neat.

I decided to order it again, read some reviews, and some people mentioned experiencing pain. Honestly, I started to doubt whether I should get it then, maybe the formula has changed.

I took a chance and ordered it - no regrets! No tingling or unpleasant sensations. Maybe it depends on the condition of the nails or the individual tolerance to the components in the formula.

Thank you, Makeup, for the fast delivery!

This is a great nail polish that lasts a long time and actually strengthens the nails. However, I was hoping that it would slightly tint the nails, as it did when I bought it a year ago. Out of all the clear nail polishes I have tried, this one is the best.

The "Korablik" nail polish is suitable for me in every aspect. I've purchased my third bottle already. The brush is excellent, it makes my nails look well-groomed and the free edge grows much faster. It also holds up quite well. I can't say that my nails have become as strong as iron or concrete, but I definitely prefer it over the Smart enamel and Evelyn. However, as always, it's necessary to try everything by trial and error.

I have very mixed feelings about this product. It worked well for a pedicure, and it looks very interesting with two thick layers. However, today was the first time I applied it to my fingernails, and it was a nightmare. My right hand was fine, but on my left hand, where I have three nails with thinning, I experienced a horrible burning pain. It felt like it was piercing through my fingers. I rinsed it with cold water, but it didn't help. I couldn't bear it, so I removed it with a liquid after 5 minutes, and the pain immediately went away. I can see that I'm not the only one who has this reaction to the product, something is definitely wrong with it.

Be careful! This nail polish caused excruciating pain - as if needles were driven under your nails and your fingers began to go numb. I quickly removed the polish from my nails, but the pain lasted for another 40 minutes. I'm not knowledgeable about the ingredients, but it's definitely a real poison. I definitely do not recommend it.

The best nail care product ever! They have recently updated the brush, making it a pleasure to apply. Thank you, make up, for the delivery!

I have been using it for 7 years in a row. It restores nails in 2 weeks after gel polish. Now my daughter also uses it. It gives a well-groomed appearance to nails and strengthens the nail plate.

The best nail coverage ever. It strengthens, protects, and makes nails extremely beautiful and well-groomed. I have bought it multiple times and have ordered it again.

Great product! I'm attaching photo evidence to prove it.

Great effect! I'm adding photo evidence to prove it.

This is a great product for strengthening nails. I highly recommend it. However, when applying it after removing gel nail polish, it's important to be careful. There might be some irritation, burning, or excessive sensitivity.

Great nail strengthener. It works effectively. I apply no more than two coats and wear it for a week. My nails have become thicker and hold regular polish better. After the first use, there was a slight burning sensation due to thin nail plates, but then the nails strengthened and there are no negative sensations.

I have been using this nail polish for over a month consistently, but unfortunately, I haven't seen any results. My nails still continue to peel and layer.

I have been using this product 505 times in a row and it really improves the structure of my nails. They grow faster and break less. Follow the instructions and apply it at least 1-2 times a week.

The product adheres well to the nails and applies evenly. It doesn't cause any discomfort to healthy nails. The only downside is the brush, unfortunately it is not well-made.

This product causes nail pain. It seems to be due to the presence of formaldehyde in its composition. Formaldehyde acts as a poison. In order to protect itself from this product, the body sends a signal and nails begin to grow stronger. It is important not to forget that the structure of nails is porous, and all substances can enter the bloodstream through them. I do not recommend using this product, although the effect of stronger nails is quite tempting.

Be very careful! The nail polish can cause allergies (or some unknown reaction). After applying the polish, the nail plate hurts and burns horribly. It feels like I've hit my finger really hard. Even a light touch on the finger only intensifies the painful sensation. The polish has been on my nails for several hours, but the pain doesn't decrease. And that pungent smell doesn't go away. So, if the smell of regular polish disappears after drying, this one continues to strongly smell on the fingers. I definitely do not recommend this product, as I am not the only one with such reviews, and it is not normal that this product causes such dreadful reactions.

The product completely fulfills its purpose. I used it according to the instructions. The product lasted for the main course (3 weeks) plus a little bit more.
The results were not immediately noticeable, but after three weeks of use.
My nails do not turn yellow, they have become strong, fresh, and do not peel, in other words, just as they should be.
I haven't used this product for over a month, but the effect still lasts (although I also don't use gel polishes).
This product worked for me. I recommend it.

I really like this product. I bought it twice at the Makeup store! A manicurist recommended it to me as a way to restore my nails after gel polish. Personally, it helps strengthen the nail plate for me. After the polish, my nails were in terrible condition. But after a couple of months, they start looking healthy again.

I have been buying this product not for the first time. It's not perfect, but it does help. Would I recommend it? Absolutely yes.

A good nail strengthener that actually strengthens nails. When applied in two layers, it creates a beautiful and well-groomed manicure. I have been using it for more than 10 years and the quality has not changed. It has been very helpful after transitioning from shellac, and now I use it constantly!

Good product. I will buy it again. Towards the end of usage, it thickens slightly.

I have been using this nail polish for several years now. I am very satisfied with it, as it is the only one that saves my nails after gel polish. My nails are very thin and they literally break. Only after using this polish for 2 weeks, following the instructions, I can grow and strengthen them normally.

I have tried other brands, but I haven't found a better one that is as effective. As a bonus, it has a pleasant milky color and applies smoothly without clumps.

Great, I'm buying it for the second time already and I'm completely satisfied with everything. It strengthens the nails beautifully, has a pleasant milky color, and leaves the nails smooth after use.

When applying several layers, it leaves a pleasant milky shade. I deduct a star for the not very convenient brush.

This nail polish is amazing, it's my salvation. I don't have the ability to do gel nails, and regular nail polish chips off within a day. However, I use this one as a regular clear polish - it looks very neat and, on top of that, strengthens my nails. It's the perfect combination! Due to my profession, I often have to trim my nails, which is a pity because with this polish, they grow quickly and look healthy.

The pain is terrible! My fingers are swollen. I do not recommend buying this nail polish at all. I applied the polish and went for a walk outside. After a few minutes, a sharp pain and burning sensation appeared. I ran home just to wash off this polish as soon as possible. It is difficult for me to type this text.

I was really looking forward to this nail polish, hoping that it would help strengthen my nails. The manicurist highly recommended it. But I do not recommend this nail polish to anyone! I regret not reading the reviews beforehand. It damages and destroys the nail plate. What kind of treatment is this?

Money wasted for nothing.

This product is really good. It makes my nails stronger and they grow better, but only as long as I use it. Without it, everything goes back to how it was before. However, I think that's the case with all products, they only help as long as you use them. You can apply it under nail polish or use it as a clear coat, either way, it gives a more well-groomed and smoother appearance to your nails. I highly recommend it!

I have been using it for a long time. It is the best among all therapeutic nail polishes.

I really love it! This is my favorite nail strengthener; it significantly improves the quality of my nails.

If you want to experience excruciating pain, take painkillers, and think about seeking immediate help, then this nail polish is exactly what you need. Of course, there are many positive reviews, some people do not experience such a painful effect. But for many, it is! It is simply poison that you apply to your nails. I applied it in one layer right after purchasing it. I bought it from the official store. The sensation is as if your nails are on fire, they turn purple, your hand starts to numb, and it feels like you are about to faint from the pain! I cried in agony until I removed the polish and took some painkillers.

After removing the gel polish, my nails became very brittle. I tried using Eveline products, but my nails got even worse. Kalyon slowly restores the nail plate. Without a doubt, I would buy it again. The price is reasonable and currently it is out of stock.

I have ordered this product before and I am very satisfied with it. My nails used to be flexible and brittle, but after the first application, they have become hard and impossible to bend even with force. I would like to thank Makeup for the timely delivery, you are the best.

Good day. I ordered this product yesterday. When unpacking the package, it turned out that the nail polish was open and leaked into the box. I kindly request attention to the quality of order packaging at the warehouse!

This is an amazing product, the best one I've tried so far. It restored my nails within 2 weeks, and if you apply it over colored nail polish, it prolongs the manicure!

I purchased this product both on Maykap and from another place. The bottles had some differences, as the one from Maykap came without a hologram. However, the brush was better and really helpful.

Good nail polish. It has good durability and a solid structure when drying. That, I believe, is its unique feature. It is similar to Eveline 8 in 1, but it doesn't burn. Apparently, it doesn't contain formaldehyde or the concentration is different. I will buy it again.

Great product!

This is a very good product that truly helps. I apply one layer at first, and after a couple of days, I apply another layer on top of the first one. I like it!

Everything is great. I am satisfied with the product and the service. Thank you!
