* Poor Adhesion: Nail polish creates a barrier between the artificial nail and your natural nail. This can significantly reduce the adhesion of the glue or adhesive used to attach the artificial nail. The artificial nail is much more likely to lift or pop off prematurely.
* Uneven Surface: Nail polish, even when it seems smooth, can create an uneven surface. This unevenness can compromise the bond between the artificial nail and your natural nail, leading to weak spots and air pockets.
* Trapped Moisture/Bacteria: If there are any gaps or imperfections in the application, moisture and bacteria can get trapped between the artificial nail, the nail polish, and your natural nail. This can create a breeding ground for infections.
* Chemical Reactions: While rare, there's a potential for the chemicals in the nail polish to react negatively with the chemicals in the artificial nail adhesive. This could weaken the bond or damage your natural nail.
Best Practice:
* Remove all nail polish completely with nail polish remover before applying artificial nails.
* Clean and dehydrate your natural nails thoroughly.
* Gently buff the surface of your natural nail to create a slightly rough texture for better adhesion (avoid over-buffing).
* Apply a nail dehydrator/primer to remove oils and further improve adhesion.
In summary, removing nail polish before applying artificial nails is crucial for ensuring a strong, long-lasting bond and preventing potential problems.
