- Acrylics can be whole or partial, used over the entire nail or simply as tips. A mixture of liquid acrylic (monomer) and polymer, which is an acrylic powder, is applied to the nail. It hardens on its own fairly quickly, usually within minutes.

- There are two current types of gel nails: light cured and no-light gels. A gel nail is typically a pre-mixed polymer and monomer gel that is first applied to the nails and then cured under ultra-violet lights. Light cured are still more common, but the advantage to no-light gel nails is less time waiting in the light. There's also the added benefit of not needing that piece of equipment (the light).
No-light gel nails are cured with a special gel activator that is brushed or sprayed onto the nail. Some are cured by being dipped in plain water.

- Gel and acrylic nails have similar results. They can lengthen short nails, strengthen nails, and make your fingers look longer and more slender. There are some various pros and cons that might help you decide which the right choice is for you. If gel nails, acrylic nails, and other choices are overwhelming you, then one thing you can always do is speak with a nail technician (manicurist) who can help you make a wise decision that will fit your needs.

- As far as finishing touches, you can paint, do French tips, or create other designs on either type of nail. Some people think that airbrushing looks much better on gel nails because they have a more glossy finish, but that is a personal preference

ухаживать в принципе никак не надо :) я хожу на коррекцию раз в 3 недели, раз в 2 месяца делаю обрезной маникюр кутикулы

цены - я платила $35 за новый сет и $20 за коррекцию

салоны я искала по месту жительства через Гугл (по району)
