I am a lisenced
nail tech and I do about 8 sets of
nails a day.
Nails before high school is a BIG NO! It can cause a lot of problems with the nail plate, but the biggest one I that he nails aren't fully matured yet and that they cannot handle having product anchored to them. Putting nails on a child can cause onycotrophia, waiting away of the nail plate an several other things that are dangerous.
Gigibair, have you ever been to a salon that isn't a Vietnamese nail salon?
