Scalp I have used it several times in the bath, but there are no noticeable scratches or stains. I have used it with care. I have wiped it with a disinfectant sheet, but if you are concerned, you can purchase and replace new attachments. It is very effective for scalp care and face lift-up. I am selling this because I purchased a new series from the same manufacturer. There is no box. Operation confirmed. #stitch_tsk You can search for products from here.
