To apply dip powder, start by prepping your nails—trim, shape, and push back cuticles. Apply a bonding agent for powder adhesion, then dip your nails into the base powder. Brush on an activator to harden the base layer. Repeat the base coat, dip, and activator process for desired thickness. File and shape the nails, then seal the powder with a top coat. Finally, buff and clean the nails for a smooth, glossy finish.
