Really gives your nails the strength it needs.
Patience is a virtue with this product, it really took a long time for this thing to work, like 2 months cause my nails needed to absorb the keratin in the product, it may be faster for others lucky you, but once it did, wow my nails never felt stronger, they don't flake, break or peel anymore.
In just a few days I will have nice luscious long nails and it's all thanks to OPI Natural Nail Strengthener.
I would have gotten OPI Nail Envy Strengthener but I didn't like it was not transparent, I like the flexibility of transparent products.
There are no cons about this product but if you use it too much after the 2 month stage your nails may become too hard making it unable to bend and withstand impact so use it sparingly.
