No. Independent contractors are self-employed. They cannot be forced to sign restrictive covenants (non-compete and/or non-solicitation agreements). Those agreements are only appropriate for employees.

Hi! I don’t share templates or samples simply because I really don’t want anyone writing their own legal documents. (I live in Florida, where we have basically no employee protections. Other states aren’t near as lax as mine, so what’s legal here likely won’t be legal virtually anywhere else.)

Find an employment law attorney in your area who is familiar with your salon’s needs and your state laws and pay them to write something binding. Before you do that though, put together a rough outline, detailing what you’d like the contract to include. They’ll be able to tell you whether the terms you want are allowable in your state/city or if they need to be altered or omitted.

Yeah, that’s a huge problem. It seems like she has some healthy hustle in her, and she’s doing what she can to build her own book, but at the same time, she’s being a little too aggressive. You should have her sign a non-solicitation agreement ASAP and include social media solicitation. If she’s your employee, you can prohibit her from taking photos. You can also fire her whenever you please–all states except for one (I believe Montana or Wyoming) are at-will employment states. She seems a little cutthroat, which could cause problems for everyone in the long run.
