I am a little bit the same as sian,Sometimes I get someone come back with no lifting, sometimes a tiny bit on a few nails, and sometimes I think 'oh my jesus what have you been doing' lol.
I have just had one lady who I knew was having some major problems, lifting after a few days, then taking off her nails, (she lives a bit of a distance away so cant just pop over to have them fixed)
I think she was a little reluctant to tell me, but I heard about the problems anyway, so I coaxed it out of her lol
If I don't know whats going on, I can't fix it,
Anyway I consulted and did an extra thorough prep, and used Retention instead of radical, I checked the other day and she has had no problems yet thankgod ...
Sometimes I think its the client not looking after their nails, and sometimes I think its either my prep or my ratio.
But YES stevie I also get lifting sometimes, You are not on your own hun,
I didn't used to get lifting on pretty much everyone whos nails I did,
But I think I have had that many product switch overs, From millenium, to NSI, to ezflow back to NSI and now CND ...I am finally settled yayy but I think sometimes Old habits from the other techniques sneak in and mess with my application methods..
