A shellac kit combines the benefits of gel and traditional nail polishes. Unlike gel, shellac acts like polish. You simply paint it on, and it hardens with UV light. However, it does not damage your natural nails.
Most shellac kits come with everything you need, like colourful polishes, a UV lamp, and nail care accessories, but simpler kits are available as well. Forget going to professionals and paint your nails like a seasoned pro with a shellac kit.
