K18 in salon treatment for repair

I saw this video of a hairdresser using the k18 chelator, mist, shampoo and then the mask along with the other products of the k18 range for an in salon repairative treatment without any chemical processes. And was wondering if anyone has had this done?

And if you had this done in the salon what were the results like vs the at home use of the k18 mask?

Basically I'm wondering if I should invest in getting the mist and the mask to use as a repairative treatment or just the mask.
