In my experience, once the nail passes the 3 week mark after being worked on it can become brittle and have breakage. If you want to maintain your nails in pristine condition be sure to book your touch up after 2 to 3 weeks of your first appointment.
It's really dependant on what you want for your nail design.
However once here I do have swatches available for you to be able to make a more decisive choice for your design.
