Hello,
I'm working as beauticain in France and I'm looking for a new nail gel for my customers. So, I would like to know what are the main trademarks of nail gel used in the USA ? And, what are the advantages and inconveniences of this products ?
In fact, I'm looking for a gel which could be the most performant : very strong, very limpid and a very good result for the custi....
Thank you !

I like OPI gels myself, when I had my fake nails done....(I am going "au natural" now)
Very durable, staying soft and pliable long enough to apply, form and shape.
I also like the colors....

However, I also know in order to get that product, one has to have a license/ business, and it's not available to the general public.

Since OPI is a worldwide product, maybe you will be able to get your hands on it in France.
