Simple, easy but a huge help for the aspect of your hands.
Wash your hands vigorously.
Polish your nail using a four sided polisher.
Dip the tip of your fingers (the nails) in lemoned water (a few drop of lemon juice in a cup of water).
Then dip them into soapy water.
Cover your cuticles with jojoba oil and massage it onto your nails and cuticles.
You can also apply some hand cream then.
Let it seat for a while.
Apply very little nail polish remover with a cotton pad, to get a better grip.
Dry it and apply your nail polish base which you can select with a treatment within.
Then put on your nail polish.
And your manucure is done.
