CND™ Strengthener RXx, Nail Strengthener for Tougher, Stronger Nails & Protection for Thin Nails, 0.5 Fl Oz, 0.5 fl oz

I purchased this item due to my nails looking and being in super rough shape due to getting gel extensions for about 6 months.. I eventually decided to give my nails a break because the nails kept popping off and or cracking so I got a plain gel manicure.. well now that the gel is starting to come off on its own my nails are breaking very easily and not to mention bending back which ofc causes me a ton of pain.. So far I have used this product once and I immediately noticed a huge change in my nails they felt and looked so much better I know it will take a few days if not weeks or months for them to be strong again but I definitely noticed a very small change in how strong my nails are right after using this product

One of the best if not the best nail strengthener and nail hardener I’ve ever used ! I’ve used so many different brands I have a shoe box full of different brands of nail hardeners and this brand is awesome.. it dries so fast and nail literally feels harder ! They are finally growing again and not splitting.. I just ordered another bottle I definitely don’t want to run out !It’s a must have for anyone having trouble with dry brittle nails or rough ridges !

Excellent product for weak nails but must use every day or it doesn’t work.Dries quickly and looks nice.

This is an excellent nail strengthening product, the directions are simple and the product is easy to use

My mom has soft, thin nails that are weak. She used this product the same day that she received it. And she noticed that it made her nails instantly stronger than before. And she mentioned that it dries pretty quickly. She mentions that it doesn’t chip throughout the day and seems impervious to water while washing her hands. She uses gloves to wash dishes, so really don’t know how well this product does under that situation. But she really loves this productShe also got another one for my grandmother, who has nails that are brittle, chip easily and one of her thumb nails is progressively splitting down to the nail bed. She has tried to have a manicurist enforce the nail from splitting any further but has had limited success. Even the dermatologist couldn’t help much. So we are hoping that this product will help. So far, it looks like it just might.

Was nice at first but Too much work really. Every certain days, layers and taking off, didn’t help my nails, turned a nasty color and I couldn’t get off. Nails are still as bad but that’s what I get for using dip for few years straight but in fairness I didn’t give it a valiant effort.

I used this product for one four day cycle. It turned my nails yellow. The cotton ball I used to remove the product was dark yellow when I was done. It also caused my nails to spilt lengthwise. It did more damage than good.

I never leave reviews, but this stuff is incredible. I recommend it to all my friends. I have the most thin, brittle nails. They always break, flake off, and I struggle to find any products to help them grow strong. But this product is the cure! Easy to put on, dries in 30 seconds, I hope they never stop making it.
