I would say that Nohea is a good 4.5. Ive gone to places that had more gel, but Nohea uses better quality stuff. Having worked in salons before I know there is a big cost difference in investing in Tammy Tailor or generic gels and "rockstar" glitter; the quality shows. They do accept walk ins but you're much better off with an appointment, (enough that this walk in queen is calling ahead) that being said I've been to many of the artists here and nine out of ten times I have been more that impressed. I wash my hands or use sanitizer at last ten times an hour at work; I am hard on my nails. My gel mannis always last 3+weeks when the chop shop left be lifting in a week. Ive noticed they don't have to shave off all of the gel base down to you're natural nails everytime since the products are so good, I've noticed my natural nails being stronger.
The location is also killer... theres just something nicer about looking out of the window to the Grammercy as opposed to a strip mall parking lot.
