Coreme Salon Care Repairtive Serum Treatment R ● This is a rinse-off hair treatment to be used once a week. ● Contains 10g x 4 sheets. ● Brand new, unused. I purchased this at a salon today, but I already have one in use and have some in stock, so I don't think I'll be using this for a while. I'm listing it while it's still new. Please understand that this item has been in personal possession once, although it is new.
