Your artificial enhancements should never hurt during application. Some techs use the wrong bits on natural nails. This causes rings of fire, and thinning of the nail plate. (The picture below shows rings of fire near the cuticle.)
The application of the product shouldn't hurt. Stinging or burning during application is a sign that they aren't using the proper product. Some salons will buy a knock off product, and put it in a different container so you are under the impression they are using a good product. Be careful which salon you choose and make sure your technician isn't causing you any pain.
If you go into a salon and it seems shady, leave. If they are doing something to you you don't approve of, and they insist they continue, leave. If the salon is dirty, or the technician is rude, leave. You shouldn't have to put up with being mis-treated and then have to pay them too!
The bottom line is if you're going to a salon where the technicians use products that aren't good, and they aren't licensed, you could leave with all sorts of problems! Choose your salon carefully, and ask to see a copy of their license. Don't be afraid to ask them questions. Any licensed nail technician shouldn't have a problem explaining what they are doing and why.
