Nail Tek Foundation Xtra 4 Ridge Filler Strengthener and Base Coat, 0.5 oz

I rarely write reviews but this product deserves one. I have terrible nails; that’s why I started wearing acrylic ones. It was exciting to have beautiful nails for the first time in my life! I was hooked. After about 20 years I got tired of going every two weeks to have either a fill in or new set. I also got tired of paying so much. I decided to take a break and let my nails grow back as they were totally destroyed. It took an entire year but they finally grew out. I went back to acrylic and that lasted only one month. I had destroyed my nails again and couldn’t keep up with the process. They are about halfway through the growing out phase and I have been trying every ridge filler being sold. Nothing has pleased me until I found NAIL TEC #4. This stuff is amazing! It fills in all the pealed areas of my nails and leaves a very natural look. It gives my nails the strength not to bend and further peal. I hove renewed hope now with NAIL TEC #4. Try it out. : ). : j

After removing my acrylics this is THE only product that makes my nails stronger because they are so thin and sore. This ridge filler is A MUST because it starts to strengthen your nails on its own. Then use the strengthener over top for 7 days (at least) and your nails are already harder and stronger. I continue using the strengthener until it starts to lift a little, then I repeat the process. I tried only using the strengthener on its own, BUT IT DOES NOT WORK. Trust me, get the ridge filler to use first and you’re on your way to healthy nails. They also make different formulas for different nail concerns.

I started using a moisturizer option on my nails to help heal splitting. Saw this and thought it might help. I used daily as recommended and then tried using with polish. Definitely helps smooth nails out for polish finish, but actually made ridges worse, so stopped and went back to moisturizer. If you want to polish it's great.

I have been fighting the nail on my right ring finger for at least 3 years. I have tried glue, nail strengthened and polishes with fibers in them that are supposed to help your nail back to normal and none of them worked. Last March the polish I had been using got lost while I was in the hospital. I kept trying other products with no help. I bough this product in November of 2023, using it regularly to deal with the split. I also used it on some nails that were coming off in layers. Last week my ring finger started hurting, couldn't figure out why until I noticed how long the nail was. My nail bed was not used to having a nail go out over it, and it was feeling bruised because my nail was nearly 1/4" long. THIS STUFF WORKS!!!

It's been 2 weeks but it looks like it's helping. I have week, splitting, peeling nails with ridges to begin with, but I had overdone the use of the stick ons that finish curing with a UV light. But using this has made a big difference already. It another couple of weeks my nails should be good again. Then I'll use this with nail polish. The ridge filling is quite good.

I was truly surprised at how great my nails looked after just one coat. My natural nails have grown out about halfway from having acrylic nails taken off. I had ridges, and after two coats, the ridges were almost completely unnoticeable. I only have one mail that the ridge was originally a bit deeper than the rest. It will probably be gone with an additional coat. I’m extremely happy with the results!

For the last 20 years I've been using acrylic, gel or dip on my nails...and they are totally hacked by now!! I decided to bite the bullet, and stop going to the salon. I got one last dip (french) and have let them grow out. The dip has kept the ends of my nails strong during the tedious process, and I just keep filing them very, very short. No, they don't look great, but after months they are nearly all grown out. However, after growing out, a few of the nails have ridges, so I wanted to find a product that would smooth out the ridges. This isn't it. In fact, I tried putting 3 and 4 coats of this product on each nail but they still aren't smooth. I like the polish and will keep using it, it just doesn't fill the ridges.

I wanted a clear polish that would smooth my nails. I was surprised that the color was a little milky. Higher cost didn't produce better nails.

Loved it , works wonderfully

Great and it keeps my nails strong

I would not buy this or advise anyone to buy, because it has formaldehyde in it. The bottle says, don’t let touch skin, causes cancer. So if you buy anyway, it’s non-refundable , so you are throwing your money away .

Used to improve mail health.. When used and hands used soap detergent, my nails went blue. Not impressed. If I was not out of the country after receiving I would return it for a full refund. Unfortunately When it arrived I used it once in prep of my trip. Very disappointing.
