If you're looking to strengthen your nails, look no further! This product is about $4 and it works amazing. I paint my nails about every week so I usually put this on first, let it dry for a little bit and then put on my nail color. I feel like this works best for me and my nails are so much stronger now. ...read more

This product is amazing for strengthening your nails. After years of using acrylic nails this helped make them healthy again. It does have a stinging effect at first but this goes away shortly after. Definitely recommend! ...read more

Loved the 7th Heaven Strengthen Nail & Cuticle Finger Masques I received in my VoxBox: POPPY BOXY!!  

First, I opened the package and placed each little cover over my finger tips--- which was easy to do. Then I massaged the tips for a bit to activate the product.  After 15 min. I removed the little covers, and massaged the rest of the product into my fingertips and nail beds. 

Review: I have tried other products like this before, but I found this one better priced, as well as the material of the covers to be better quality-- a plastic instead of a cloth. This allowed me to do other things while I waited for the product to finish it's job. 

Verdict: I will be purchasing this product instead of the other one I have been using for the last two years. Same kind of result--this option is better priced and I do not have to order it in the mail (it can be found at my local store). I recommend this product if you have a dry nail issue or cuticle issue. ***  I received this product complimentary from Influenster, but all my opinions are my own. ***

This nail care product is amazing! It has really done wonders with my nails. Before I started using this, my nails would grow on their own but was paper thin and broke off easily. Now they are strong and grow without breaking all over the place. I got 2 bottles of this for less than $10 from Amazon and I have never regret it! ...read more
