F.H.
I have worn acrylics for the last 25+ years. And I take them off every few months and leave them off for a few months. Then I always hate how they look and put them back on.
However, I started taking some vitamins a couple years ago. After I took my nails off to let them breathe, they grew back really strong, I was shocked! Must be the vitamins! So even tho I still wear acrylics (habits are hard to break lol!) I *know* my vitamins are working because my real nails are strong under them. =) Here is a link if you want to check them out: http://www.GBGisIT.com They are the 10 in One and are chewable or liquid for quicker absorbsion into the body. And they have added probiotics...awesome! Good luck!!!
