i installed a client with ultra sonic cold fusion and after 4 days she text and said she had washed them and gone really dry and she couldnt brush them. i found out she used pantene shampoo as she had run out of extension shampoo, i told her to use the correct shampoo again. she just text and said she had a conditioning treatment at a salon and they told her the hair was rubbish, the suplier i use is usually really good never had this trouble before.
apart from contacting the supplier what else can i do? advise please
