It's so difficult for the public to recognise what is a good nail tech.
For a start, I would be wary of anywhere using a nail drill or efile as unless you are in extremely good hands you are very vulnerable. Plus, if they are using the wrong kind of acrylic (MMA) they will for definite be using a drill because these nails set like concrete and you won't touch them with a handfile. Have a read on MMA and look out for telltale signs like unmarked bottles (why, if you use a reputable brand, would you decant into an unmarked container? My Ezflow bottles and powders are out for all to see).
You need a tech who is using EMA, not MMA. Only one letter different, but oh boy what a difference! They won't show you the small print on the bottles, but you could ask.
You might feel uncomfortable asking that question but my honest opinion would be that a good tech using a decent product line WOULD NOT MIND IN THE SLIGHTEST, I know I wouldn't.... it's such a breath of fresh air when people are a little bit educated about nail products. You could also ask if they are going to "rough up" your natural nail when they apply the acrylic.... the answer you want to hear is that they are going to use no more than a 240 grit block, but that's a bit detailed so look for confirmation that it's going to be gentle.
Ask what product line they use, too, CND and Ezflow are excellent, I'm not going to badmouth any product lines but I can vouch for these two, Ezflow because I use it, and CND because . . . . . well, because it's CND lol
Lastly I would ask for an experienced tech, don't be a cheapskate and book in with the trainee unless you are prepared for "teething troubles" .... not knocking trainees, though, we have all been there, but it has to be said if you want a trouble free set there is a much higher chance of getting one from a tech with a few years' experience.
Whoever would have thought having your nails done could be so complicated?
AHHHH
and just to finish off
DON'T DON'T DON'T PICK THEM/PULL THEM OFF, IT WILL TAKE LAYERS OF NAIL PLATE WITH IT AND WILL BE NOBODY'S FAULT BUT YOUR OWN .....have a proper removal done or message me and I'll talk you through it step by step if you want to remove them yourself, believe me it's worth getting it done properly though xx
