Hey geeks I’ve had a client with a few of her ends turning pink. I’ve explained this can happen usually abroad and have told her the general causes, gave her some Malibu c crystals and thought that would sort it. ( she hasn’t been away it’s happened at home in UK) it it still a bit pink and she has asked me to come and replace some. I’ve told her it’s not the hair it’s probably the minerals in the water and replacing the hair it could possibly happen again. She is ok there isn’t an issue but I am curious as to how others deal with this?
