Nail TekIntensive Therapy 2- For Weak, Thin, Soft, Peeling Nails, with Protein Formula, Reinforces, Thickens Nails, Promotes Strength and Flexibility, 0.5 Ounce - 1 Pack

Honestly the best thing readily available for nail growth and strength. Hardens nails without making them brittle, strengthens them without making them super hard and thick with buildup, and causes growth to be super fast. Only addition I would want would be for it to be lightening and have the option of a matte formula as well. I'll always rebuy this when I run out.

I bought the Intensive Therapy at a big box store that starts with W, fell in love with it, came to Amazon to check out other items from the brand. This duo cost me less than the single bottle did at the store. I'm either giving my mom my extra IT or I'm saving it.Background: I have extremely THIN peeling nails because of nutrient deficiencies that I need to work on. I do my nails a lot cause it's my passion, so my nails go through a lot of crap. But even when I take long hiatuses from painting them, they are still awful. I paint my nails 1-3 times a week, sometimes more, sometimes less. I've been using the IT for about 3 weeks, Foundation for about a week. My nails are about as bend-resistant as a generic solo cup if that makes sense. This is important to take note of.First lets talk about Intensive Therapy. WOW this stuff is great. After 2 or 3 uses, I noticed my nails were growing like crazy, polishes were applying smoother, and my nails started to feel thicker. They're starting to feel like real nails. I'm amazed. I have tried practically every strengthening base out there with no results. I will never stop using this stuff. I apply it 1-2 times a day if I'm not wearing regular polish. If I am, I apply a coat over my polish every day like the box says. The key to this stuff is CONSISTENCY. Use it a lot!Now for Foundation. I love it also. I haven't used it long enough to form too many opinions yet. But anyway. I have pretty ridge-y nails, so when I wear polish, you can see them and it ruins the look. They look ugly as you know what if I don't buff them, but that's bad for your nails. I applied this stuff and I was amazed. I looked at my nails from different angles and I hardly saw ridges. I also enjoy how it looks on it's own. It has a matte finish and makes my nails look thick.Bottom line, I really love both of these. I'm gonna experiment with layering them. I won't try any other bases for a long time. Even if this stuff gets gummy fast, I won't mind, because it's RIDICULOUSLY cheap at this price. Each one is about $10 at the store, which is not economical to buy every other month. You get both of these for less than that! You get them for the price of two crappy non-prestige-brand base coats like a certain brand that rhymes with Rally Manson. I am officially Nail Tek's newest fan. I love you NT!

WARNING: This review will be long. If you'd prefer to avoid my rambling, I will state the necessary information about this product now: 1.) My nails have been weak and peeling my whole life, and they are now strong and stable. 2.) The combination of the Foundation II and Intensive Therapy II has worked better than any other nail treatment I've tried. 3.) While the Foundation II can get pretty gloopy after a little while, it is absolutely worth a repurchase when this occurs. 4.) By using these two in conjunction with one another, my nails have grown out past my fingertips for the first time in my life! 5.) Buy it! You won't regret it.Now, on to my life story. I have always been a nail fiend. I love painting them, trying (and failing) nail art, experimenting with gels, acrylics and press-ons. Part of the reason I was always trying new things, even as a little girl, was that my nails were soft and peel-y. They always peeled in big sheets or tore off at the tip. This started me on the path to nail enhancements, which was a BIG mistake.I loved press-on nails. I used them countless times because I could do them myself and they were cheap. Unfortunately, I didn't want to wait and soak them in acetone to remove them. Instead, I figured chipping away at them and pulling was a better idea. Needless to say, this ruined my nails. I then tried at-home acrylics kits. These never turned out the way I wanted, so I ended up pulling these off too. (Not the smartest nail clipper in the...never mind). I then tried gel polish, because regular nail polish always peeled off of my nails in sheets. I got sick of the gel polish, and guess what I did! Yep, peeled that too.At this point, my already weak and peeling nails were destroyed. I never took good care of them, because they were never in good shape in the first place. But, after doing some research, I decided to try Nail Tek. I purchased these two items and began my "detox" and treatment.I saw a difference in my nails after about two days. I noticed how much stronger they felt and that the polish I layered over the Foundation II hadn't peeled (which polish usually does in about two hours for me). After a week, my nails had drastically improved. They had actually shown signs of a bit of growth, and were much stronger. Nail Tek allowed my nails to grow out quickly, which meant the damaged areas of my nails were grown out. I was able to start fresh with no damage on my nails, thanks to this product.My nails have NEVER looked this good. They grow out past my fingertips, are strong, yet flexible, and don't tear nearly as often. Also, the Foundation II as a base coat makes my polish last for three days or more, which is HUGE for me. I really cannot say enough about this product (clearly, as I have written a novel here). I really urge you to try it, because it has changed my nail life. Thank you to anyone who made it to the end of this thing. Good luck, and happy polishing!! :-)

Nail Tek has great products! If used as instructed you will be very happy at the result.

I have weak, soft nails that are prone to peeling in onion-like layers, which happens to be the exact problem this product claims to solve. And wow is it effective at doing so! I've used this as my basecoat for nearly a decade now - enough so that buying it in the bulk 4-pack is simple logic. It's effective as a basecoat and prevents my nails from being stained even by highly pigmented polishes (and I am very fond of rich deep royal purples and emerald greens), and it helps keep my nails literally in one piece. Instead of the short chipped off nubbins of my 20s, I now have smooth nails that I get to pick the length of - I need to actually file them shorter every other week or so, since they now grow out like normal.

I've been using this for about a month and a half. I've used it as described, applying it daily for a week, then removing it and starting fresh. It's nice when it's on, and after several coats is seems to protect my nails well. It may have increased my nail strength a bit, but I still have breakage and peeling. I also found it started to peel and chip after about three days, no matter what I did. It hasn't hurt my nails. It might help a little, but not much. I'll keep it around as a base coat or clear nail polish, but it looks like my quest for a good nail strengthener continues.
