I don't a client Sunday and she tried dip dying her extensions herself and it didn't go the colour she wanted, she then went to two different salons and they both said the hair is not 100% human hair as the colour won't take, she has asked for a refund but I told her I am happy to remove the extensions for free but as she has dyed them them the supplier won't accept the hair back for a refund but happy to give her the supplier details, I'm worried and it's knocked my confidence a lot as I spent alot of time doing her extensions so don't want to give a refund as it was my time. What should I do help
