I'm not sure if that's what it's called, but I've heard of this Japanese straightening treatment where you get the straightening done, then you can't wash your hair for 2-3 days, and then you go back to the salon and seal the treatment?

Does anyone know a good place in Hong Kong to get this done? I heard the wrong technique could really damage your hair, so I'm interested in a place which can do this properly as opposed to a cheap one.

Has anyone here had this done and have any personal exerperiences to share?

Any ideas much appreciated, thnx!
