Nutra Nail 5 to 7 Day Growth Treatment - Fast Keratin Nail Hardener & Nail Strengthener for Thin Nails, Brittle & Damaged (0.47 Fl Oz)

Absolutely amazing!!! This product alone has save my nails. After YEARS of applying press on nails, my nails were brittle and fragile. Saw such an improvement after one week and now my nails won't stop growing! They are the strongest they have ever been!

This is the GOAT for natural nail strengthening and growth. I paint it on and my nails absorb all the vitamins and moisture. Then I follow up with my favorite base coat. My nails are stronger than ever. One bottle last you a very long time. Worth every penny!!!

The treatment is easy to apply and soaks into the nail. I’ve used it for about a week and my nails feel harder. I have soft nails that tear easily. Hopefully I will see results as they grow.

Based on positive reviews I ordered this and got the bottle quickly. When I opened the box I noted the bottle was an 1/8" short of full. I assume this was normal. I used it for a couple of weeks and was pleased with the results. Nail splitting fixed and easier to cut toe nails with scissors.Based on my results my wife ordered some for her, noting she could not use mine because of chance of cross contamination. Her bottle was FULL (no 1/8" gap).About this time I noticed my finger and toe nails were dirtier than usual and noticed some faint red lines going down my cuticles. I now suspect my bottle had been used and was contaminated. I tossed it.I also note, from a manufacturing perspective, the packaging is not 'secure'. The box is not shrink wrapped or taped and the lid is not taped.

I have used this product for over 6 years, and it does harden and strengthen nails and helps them to grow.S. Scott

Not what I was really looking for,, not as expected??

I’ve been using this on and off since July 2024 and this something I recommend to others who struggle with weak brittle nails (I’m an ex acrylic girl) and who are avid nail biters! (When I get anxious I pick at my skin and nails!) I love to see my nails literally start to grow in a few days once I start using this. My nails used to grow out but would break from being so brittle, now they are strong and do not bend! I love this! My nails were such an insecurity that now I love to not even have polish on them!

This product saved my brittle fingernails after I reacted to Acrylic Nail products. It's wonderful!
