I love my seniors...But I have this one who is new to my chair she used to go to this other lady who retired and her clients were split amongst us at the shop.Well I just can't do what Sharon does.So help me I put her color on and she freaked out..This isn't the same color sharon used..I showed her her card with Sharon's handwriting saying this is your formula.No this looks Black you are making my hair black Me and my coworker tryed to explain the process of color oxidizing.After I washed it out and dryed it and it was the same color instead of saying she was sorry she gave me a hard time about something else.I told her I had enough I have been doing hair for 20 years and I know what I'm doing.She said do you want me to go to someone else.I said yes.She said she was sorry and asked if I would give her another chance.You think it would end there but the next week she sat in my chair and said this week can you make the top pretty like Sharon did..AHHHHHHH!!!!!!!
