First of all, wash your hands with soap. The water softens your nails, which eventually become easier to cut. Take the clipper, and cut your nails one by one. Make sure that you don’t go too deep while doing this.
You are recommended to cut only the extra part of the nail. Going too down might cause injury. Start from the index finger, and slowly reach the little one at the end. Always hold the nail clipper firmly.
Now, it is the time to clean your nails. Find the scraper tip, and scratch out the dust, if there is any. Again, there is no need to be an extremist. If the sharp tip does not bring out the whole dust, use warm water to wash it.
You might have cut your nails unevenly, so filing is very important. Get a nail file, and smooth out the edges. Try to make them as rounded as possible. Do the same with every finger.
The last step is to have a close look at your nails to make sure that the job is completed. Now, wash your hands with water, and apply a moisturising lotion to give a fresh and clean look.
