Honest reviews


Brittle Nails Beware

I had to give it at least two stars because it is effective at helping nail polish adhere without chipping. However, if your nails are prone to peeling or chipping, this will make them more brittle, dry, and prone to peeling. Switched to Nailtiques #2 and it helped them recover.

Makes a great base

This plus Nail Tek II has given me tough as iron nails. I have tried absolutely everything, and this works. I swim several hours a week, and still have great nails. I top it off with Revlon "Nail brightener" — just one thin coat.

Good base coat

It holds what it promises – smoothes out rigdes, and provides a smooth and matte base for the nail polish to be applied to. Good brush.

Terrible, Turns Nails A Disgusting Yellow

I went by the directions on the package. You keep adding layers of filler. This made my nails a grotesque yellow color.

Works good for me

The package came a bit banged up but I received it quickly and the bottle was in good shape so that is what matters to me. I have used it twice so far. It makes my nails nice and smooth and my nail polish seems to glide on nicely after using it. Will update if anything changes but for now I am liking it.

Good product but took too long to arrive

I like this product. It creates a good matt base coat and primer which helps nail color go on smooth. It fills ridges in pretty well too. But it took almost 2 weeks to arrive, so next time I will just go to the store and get it myself.

Great base coat

Covers the ridges while nourishing your nail. It helps protect your nail from yellowing if you use dark shades and leave the nail polish on pretty much until you’ve peeled it off. Also it helps the color nail polish stay on your nail longer. Will definitely buy again.

Okay For Now

This product is pretty good but it wasn’t what I was looking for, though it does strengthen your nails as is says it doesn’t last very long under your polish, though I’m sure it would be good if you use it by itself and can keep adding every few days to keep your nails stronger. I was hoping it was more of a strengthener base coat but it’s not and in some cases the polish seeped under and stained my nails which shouldn’t happen with a ridge filler but it did.

Amazing nail treatment

I love this base coat. You can use it alone to help repair nails after acrylics. It noticeably strengthens the nails and fills in any ridges! I will definitely purchase again!

Works the best

I’ve tried so many hard as nails types of base coats, that didn’t work, so had pretty much given up being able to wear polish on my natural nails, without them peeling and cracking. That is, till I read the reviews for this nail strengthener. There were enough positive comments, that I was willing to give this a try. I’m glad I did, because this nail strengthener, truly works for me. I’ve used it for almost 3 weeks, by putting on 2 base coats, then colored polish over that. My nails looked better, even after the first week. Even with the polish on, my nails that typically break and peel when I wear polish, are staying in remarkably in good condition.

Hides ridges!

I have had ridges on my thumbnails as long as I can remember, but this product makes them smooth! Also, it seems to be almost impossible to remove. The girl doing my next manicure had to soak in polish remover for 10 minutes to get it off, but it lasted for weeks!

Charmaine Allenspark, CO

Fills ridges in nails beautifully but chips easily

I tried the Nailtek Foundation No. 2 because I have a lot of ridges in a few of my nails and it worked beautifully to smooth them out. Unfortunately, it also chips very easily. To fix that problem, I use a coat of OPI Nail Envy underneath, then put on the Nailtek No. 2 foundation, put on polish and then use another coat of the OPI Nail Envy as a top coat and it works like a charm!

Oh my gosh this stuff is great!

I had given up painting my nails because the polish would pop off same day due to the ridges on my nails. Also, my nails split on a few that would weaken them. My daughter told me about this foundation and from the first use it works amazing. Now my nails are stronger than ever and polish stays on for four days before chipping.

It’s okay, I really didn’t see a difference.I have used it twice already. So I guess I have to use it more often to see any kind of results because I haven’t seen it yet. But the way he goes on it’s smoove!

I have thin, cracking, peeling nails.

This product was brought to my attention by a beauty guru/professional. I have been using this for about a week and my nails have not broken yet. I have been trying all different types of hardeners all my life and none have worked, my nails will still keep breaking farther and farther into my skin and bleeding no matter how short I keep them. This product is my favorite nail strengthener. Its thin, so I apply about 4 coats, it drys in seconds, and then two coats of nail polish and then two of a nail strengthening top coat. The one I use is Sally Hansen Diamond strength.
