I have weak nails that never grow, they always break off, so I bought this and I saw results in the first 2 weeks! I use it a base coat and paint my nail colour over it. My nails are much stronger, they've grown loads, and they actually don't peel as much. I definitely recommend this product if you have weak nails :)
Great for a top coat.
I never really noticed much of a difference in the health or strength of my nails when I wore this alone or under my nail color. It did however make a great top coat. It has a great shine and holds for up to a week. I will continue to use to, but I probably won't buy it again.
