Is the Tresemme dry shampoo any different from the Batiste dry shampoo?
Same here in US, Tresemme is $5-10 cheaper than Batiste shampoo. I’ve tried both as well, but I can’t really differ one from another besides the smell. As for the grease look that’s the effect of volumizing shampoos. Maybe you should try a different one which really suits you, maybe one of these shampoos for fine hair like Kenra or Nioxin.
I live in Canada and here the Tresemme is actually a few dollars cheaper than Batiste (I guess because Batiste is an import?). I’ve tried both and would never use anything other than Batiste again. It goes on dry and gives hair a lift of volume, whereas Tresemme goes on wet and, I think, gives your hair an even greasier look. Definitely stick with Batiste–and thank your stars it’s so cheap over there!
