A new client came in today wanting an infill/rebalance. She had her nails done at another salon and although i'd prefer not do fill in ovedr someone else's work, ahe refuses to remove the existing product. I don't have much experience with acrylic, as I normally work with gels, so I am wondering if there is any problem with using a different brand of acrylic over the exating product. I think her nails are done with Star nails products and I'm using nsi. She has what looks like an extreme white french manicure and pink powder, I use pink powder with a natural white fm. Any advice on how i should proceed?
