I'm pretty set in my ways when it comes to painting my nails, I've been using this little combo of products for a couple of years now and I wouldn't be without them! Although they do come in a little expensive, I try and purchase from eBay where I can usually find them much cheaper than in store.
OPI Nail Envy Original Nail Strengthener
You may notice that the bottle I have looks different to the one shown on Boots, this is because its the old style of packaging, probably why it's reduced price on eBay, however the seller I have linked above is where I've purchased my last two bottles from, and haven't found any problems with them. This base coat contains strengthening properties in the form of wheat protein and calcium, which in turn, along with proper care of your nails will make them harder, longer and stronger. As I say, I've been using this for a good couple of years now, and I have definitely noticed an improvement on the natural condition and appearance of my nails. They also grow much faster and stay long as they don't break so easily anymore. I would definitely recommend this to anyone who struggles with weak and damaged nails! The formula is easy to apply, dries quickly and to a slightly glossy finish, perfect for just glamming up your natural nails.
Seche Vite Dry Fast Top Coat
First of all, I'll start with the only bad point about this polish - the smell! The fumes this polish gives off are unbelievably strong, so I'd definitely advise opening a window before using. Other than that it's plain sailing... This polish not only adds a superior, professional looking high gloss finish to your manicure, but it also dries your previous coats of nail polish super quick, in as little as 60 seconds depending on how many undercoats you've used. I also find that Seche Vite prevents your nail polish from chipping, sometimes I've known my mani's to last over a week without a chip in sight! It's no wonder that it's acknowledged as the World's finest top coat!
My natural nails and finished manicures really have benefited greatly from using these products and I'd have a hard time finding an alternative if either were to be (God forbid) discontinued!
