You're not getting fingernail extensions or anything, right? If you ever should, make sure they don't use MMAs - those do really bad things and they're not supposed to be used. I think it's a fingernail glue. If they're reputable they shouldn't use them.
No, just my natural nails. I've never really had very strong nails till I went on this low carb diet! My nails toughened up, go figure!!
I didn't know what MMA's were...but the shop in Walmart doesn't use them...they have a placard on the wall stating as such. Don't know about the little shop down the street, but I guess it doesn't matter since I don't get fake nails.
