Prepare your nails with UV Gel base coat, UV Gel Black Colour Coat, and then with UV Gel Top Coat. (Note: Unable to get same holographic effect with normal top coat)
Use a small brush (e.g. eyeshadow brush) to apply the Unicorn Holographic Nail Powder onto your nails.
Repeat the step until you are satisfied with the holographic effect.
Seal it with UV Gel Top Coat.
