I've watched this thread with interest, and not having seen the article am only guessing at the technique. I think what we have to remember is that when you are very early in your nail career it is best to get your technique sussed before you move on. Once you have those difficult skills under your belt and can pull them out of the bag whenever you need them, then experiment, Yup think outside the box!
We have seen that one of the main things we believe that make the NSS attractive is price and their incredible speed! So whilst we love our advanced skills a lot of the public really don't care! Young girls in particular love them to look as white, square, bold and brassy as you can get them because they WANT people to know they have had their nails done! It is those young girls who seem to be attracted to the NSS to the low price/ high speed/ non appointment ethos. They are often one off clients, so why not increase your profits by adding white tipped sets to your service menu?
Dont knock it til you've tried it!!!!!!!!!
PS over exposure MAY occur if you repeatedly do this, the chances of a reaction occurring at their first visit is very unlikely. If they keep them up then they switch to infills, and if gets time to have a new set then the natural nail will have grown sufficiently to apply the tip compeltely over the nail.
