Work as a team with your client.
I usually find that for those who are just starting out with enhancements, they'll get lift.
They're banging them about, not using their oil, not wearing gloves when house-keeping (cleaning products can be terrible) etc.
I explain it's an adjustment period. We keep them a tad short. I assure them that this phase will pass and we must work as a team.
Nails are JEWELS, NOT TOOLS!!
I remind that while enhancements are stronger than natural nails, they are not indestructible. I'll point out my nails - which are usually grown out to some degree - without any breaks, chips or lift; and tell them "you can do this too", you just need to learn how to use your hands.
Often clients will say "but I'm not rough with my hands"
I'll point out to them "you know how some people walk heavy thump thump thump, and some people walk softly?" Neither one or the other makes a concious effort to walk like that. Same thing with your hands, you may not think you are rough, but clearly you are from the lift.
I'll show with my hands, examples of ways to use them for everyday things, that make a difference.
Usually, by the 2nd or 3rd fill/rebalance, they have seen the light and are working "with" me and lifting is an issue of the past.
If it's not a question of how they are using them, BUT they are addicted to hand creams (usually full of petrolatum/petroleum jelly/mineral oil and other useless fillers), I explain to them that the cream is the problem, and to switch to the oil. I explain how it works. I use the example "you know if you put oil on a rusty door hinge, the squeak is gone but the rust is still there? Same with creams full of mineral oil or petrolatum. They hide the problem but don't fix it, they only sit on the skin etc. Natural oils are absorbed and actually FIX the problem"
I find this approach works very well. Because 99% of my clients are referrals, they have only to look at the nails of the person that referred them to see the truth behind my words. They know that so-n-so's nails don't lift, so it must be something they(the client) is doing wrong and not me, so they are willing to work with me.
