Hairdressers sound off!

Or anyone that knows either is fine, so I’m going to get beaded extensions next week they’re 22inches my hair is just below my collarbone. But anyway, we’ll be doing an all over color Bc my hair color atm is kind of patchy so we want everything to blend well. But the point is she told me my total will be $1100 and that’s totally fine no problem but I just wanted to ask what kind of tip do I leave for that? My whole life I’ve only ever gotten like $50 haircuts and trims so this is very different for me. I just want to make sure I don’t insult her and want to make sure it’s the appropriate tip.

Also, sorry for posting in this group I posted in a hair one but it’s not active at all.
