To apply dip powder, begin by preparing your nails: trim, shape, and push back cuticles. Gently buff the surface, then apply a bonding agent. Dip your nails into the base powder and brush on an activator to harden the base layer. Repeat the process of applying base coat, dipping, and activating for desired thickness. File and shape the nails, then seal the powder with a top coat. Finally, buff and clean for a smooth, glossy finish.
