Hair glazing?

ANyone ever do this at home or at a salon? My hair looks so dull, I was wondering if this gives it a little life, or enhances the color. Any recommendaions or experiences? TIA

Re: Hair glazing?

Mine hairdresser did glazing last time I got my color done because I went darker.

It's much glossier still, and it's been a month almost. And I swear, I can go three days without having to wash it now when before I could only maybe go one.

Don't know if that's the darker color or the glazing though.

But I like it!
