The Japanese Manicure is a buffing nutrients deep into your nail to make your nails more healthy and shiny without polish.
The procedure does not include a color,design or applying any other products besides a beewax.
This manicure lasts about two weeks. It depends also by your daily routine and by how much you use cleaning products.
The procidere is not going to help if your nails are really weak after gel,acryl, etc. It's better to wait a week or two after removing a matherial and then do the procedure.
