First of all, if you are doing this at home, do remember to keep the following things by your side and they are: aluminium foil, nail polish remover, a nail cutter, a nail file and an orange stick. Either keep some rough cloth or newspaper below your hand as it will get messy.

Step 1: The initial stage starts by using a nail file for scratching the surface out and nail polish apart. You can also cut your nails a bit shorter to make the process easier.

Step 2: Now soak the required cotton balls in the nail polish remover, wrap around your nails and wrap a foil over it. Leave this on your nails for about 7-8 minutes.

Step 3: Now use the orange stick to peel off the nail gels.

Step 4: Now the last stage includes wiping off the residual part left on the nail area with a nail varnish remover, put some moisturizer with a nail cuticle oil. Afterwards, you can file them again and paint your nails with a beautiful color. 

By doing the above procedure on your nails, you will definitely get some good results. Do share your experience if you are doing at home itself. Good luck !
