1. Don't cut your cuticles. This is really important,because this will not only make cuticles look worse (red, swollen and ragged), but may also land you a nasty infection that harms the nail bed and leads to permanent nail damage.
2.Moisturize, moisturize and miosturize. This is the most important thing, in my opinion. It will make your hands feel softer, but it will help your nails grow faster (especialy if you moisturize around the nail bed).
3. Avoid rough emery boards. Those old-fashioned emery boards are to harsh for nails, causing small fissures and cracks that can lead to breakage. Instead use file nails with a smooth, fine file and don't saw back and forth, try to file in one direction only. ( try a nail file like the one in the picture)
5.Swipe away that old nail polish. We've all been guilty of wearing a manicure out to this unflattering point.
6. Keep a nail file handy for emergencies. It is important to keep one with you, to smooth any rough edge and prevent further damage.
Hope this is going to help you to have the nails you are dreaming about.
