nail care, strengthener treatment, vegan, Hard To Resist Advanced, 0.46 fl oz

I have tried them all: OPI, Dior, Sally Hansen - BUT I ALWAYS come back to this one. Here is why: 1) it lasts long (if you apply two layers); 2) it gives a gel like clean french look; 3) it really hardens/strengthens weak nails - give it a few weeks; 4) the brush is perfect for precise application; 5) Did I mention the nails look healthy and happy? Love it! Highly recommend!

I've always had thin/flaky nails which never grow more than a millimeter or so past my nail bed. I've tried many different growth serums etc but this has been the best so far. It stays on for a long time without chipping and noticeably helps with growth and strength after a week or so.

I have been using this for over a year in combination with 2 more products posted on the photos. I put a first coat of the Essie one and then another coat of the Keratin one. I let them dry before applying 2 coats of my natural nail polish. I have extremely brittle nails. The chipped and break from the corner of the nail bed. But using these 2 products together has helped them tremendously. Context: I used to be a nails bitter since childhood. I have never used gel manicure or UV, only once and it didn’t go well. I did use a handful of times press on with regular nail glue. The reason why I give it 4, is because the product advertises it hardens the nail, and this did not happen with me. It helps them grow and I can have them a bit longer, but not strong and not as long as I want them to be before the chipped right from the corners. You can see in the photos a couple of nails that were shorter and with 2 applications for the last 14 days, it has from from zero to where you see them. (Nail in question is my index finger).

This really works for me. I had ridges and nails that would literally ache if I didn't have polish on them. It probably has taken a few months, but I noticed my ridges are gone and my nails are getting stronger. The first nail product that really worked for me.

Great product. My nails have not been this healthy in decades

Great nail strengthener- highly recommend. I use it after gel polish to help repair the damage.

Second time I'm buying this. I work at the hospital & use hand sanitizer all day long so my nails are very brittle. This is a life saver. It dries quickly, I did notice the difference after about a week of using it. However, I do apply 2-3 layers. You need to let it dry fully between layers otherwise the polish forms little bubbles. And yes it does peel if you play with it, like other strengthers I used, but it is the best one I had by far.

Works well and lasts a while. About a week until I have to reapply.

I ended up being stubborn and the last set of acrylic professionally done nails, I let them just grow out naturally. By the time there was about a half way point between my natural nail bed and the remaining acrylic nail tip, I started applying this polish. Not only did it keep those raggedy side pieces from catching against clothes and hair (aka brushing and washing hair) it helped nourish my incoming new nail bed. Once I was able to safely pry the last bit of the fake nail tips off, I continued to just coat my whole nails and it felt, and grew back healthy. The only reason I give it four stars vs five is because the polish chips easily, it comes off when you wash dishes, its not the most permanent. But I just reapply one little coat again and again and I cant wait for the rest of the brittle tips of my nail to grow out. But I cant say I wont keep using it because it just feels so silky and smooth and looks shiny. Highly recommend it regardless.

Super product! Makes nails really strong! Have used for a year now.

My nails still split. This is just a very good clear nail varnish.
