I say no. Don't do it. I've been told by many many many people that fake nails damage your natural nail and weaken it, making it that much harder to go back to being all-natural.
Here's what I have used with TREMENDOUS success to keep my nails strong, beautiful, healthy, and growing fast! Hoofmaker. You can buy this product online, but some Walmart stores have it in their pet section. Horse trainers and breeders use it to build strong hooves on their horses, but it's nail beauty's best kept secret!
Here's how I use it when I want my nails at their most beautiful:
Just dab a little on your fingertips, then rub the lotion into your nails. [NOTE: A little goes a long way - I've had the same tub of Hoofmaker for about eight years. It's definitely worth the money.] Do this every night (and even every morning if you're in a hurry to get your nails looking hot). You will notice an improvement within days. Keep a fingernail file at your bedside and do a 60-second filing every night, just along the edges - I'm talking about a really quick file job, nothing that will take more than a minute.
You will notice that your nails will grow faster, they will look healthier, they will be break-resistant and even feel thicker/stronger. I find that I actually have to trim my nails with clippers because they get so long and just won't break. I've had people exclaim over my nails, and they just can't believe they're real and that they're so healthy.
Also, I don't wear nail polish. That just dries my nails out and makes them brittle. But I find with the hoofmaker that I don't need polish.
Give it a try before destroying your natural nails with fake ones (and the chemicals that go along with them).
EDITED TO ADD THAT this suggestion is a WHOLE lot cheaper than getting a manicure every few weeks, too! Save your money and use Hoofmaker, then buy more Cathe DVD's with the money you saved.
