How to get glinty hair?

I originally used pantene shampoo and my hair was not shiny at all but it went all goldy glinty in the sunshine, about three weeks ago I switched to herbal essences and I noticed it got ALOT shinier but no longer glints as much in the sun, so does it have something to do with the shampoo I use? and is it possible to get glinty and shinier hair?
