If there is oil on the nail plate or the prep has not been thorough enough, you will get lifting within 2/3 days, likewise if the l&p has touched the skin.
As Angie says, lifting shouldn't really happen with proper application . . . if they look after them properly, which includes having maintenance when its due. not trying to drag it out to four and five weeks.
If a client wears her nails too long and goes far too long between maintenance you could see some lifting, but this would not normally happen with a well behaved client lol :smack:
