Should I give my hairdresser, who's getting married, a gift?

I’ve been going to this person for about 8 years. She was initially at a salon I used to go to, and when that owner sold his place, she moved to a new place and I see her there, now. We’re not friends outside of the professional relationship, and I’m not invited to her wedding. Kind of similar to a bartender, she tells me personal stuff and I do the same, as we chat for the few hours that I am there, and we’re friends on Facebook.

Should I get her something for her wedding, like a bottle of champagne, or is it not necessary?
