SZA's Nail Artist Melissa Samuel Shares Her Beauty Essentials, Including a $5 Cuticle Oil

Kokoist Velvet Matte Non Wipe Top Coat Gel ($20)

This matte top coat from Kokoist is another tried-and-true product Samuel frequently uses on her clients. "I like to do a lot of my designs in matte since I do a lot of graphic, bright colors; and the matte makes it pop," she says. "A lot of people are scared to use matte top coats because back in the day they came off shiny before you left the salon, but Kokoist's coat will keep your nails matte until you remove them."
