Can you sue a hair stylist for cutting hair extensions and ruining them when asked NOT to cut them when trimming regular hair and some areas lost 12in of hair and have before photos within a week?

Yes, you can sue a hair stylist for cutting hair extensions and ruining them when you asked they not be cut while trimming regular hair. The lost of 12 inches of hair is a lot, but having before and after photos will help you if you are able to sue.

Added: The likely outcome of such a suit is the value of the cut hair. This is not the sort of suit where you would be able to receive punitive or other damages. Check with your local small claims court about filing fees and procedures. Depending on your state, you may also need to formally request that the stylist reimburse you for the extensions prior to filing suit. This is referred to as a demand letter.
