Do you need to use Acrylic Primer for Acrylic Nails?

Answer 1

Its always wise to an acrylic primer.. But if you use the gel nails they last longer, look nicer and are easier to maintain.

Answer 2

You have to just let your nails grown out. They are thin because they sand down your nails to put the fake ones on. Just get some growth formula clear nail polish and try to stop messing with them. Keep them trimmed VERY short or they might tear past your nail bed which can be extremely painful. This is one of the drawbacks of acrylics. Once you start getting them, you can't stop, or you'll have to go through this. It will be a month or two before you'll see your nails healthy the way they used to be.
