Reddit mentions of Tresemme Fresh Start Dry Shampoo 5.7 oz.

Ok, I've tried a few dry shampoos and here's what I came up with.

• Got2b Rockin' It - This stuff works the best, though one can of it does not seem to last very long.
  
• Suave - This dry shampoo works very well. It's almost as good as Got2b's. One weird thing is that the directions say to spray the powder in, then press it with your hand so your heat can help it work. I haven't seen ones like this before, but it does work better if you do it like that. It's definitely great for the price.
  
• Tresemme - I don't know why I've tried this multiple times, because each time it was just terrible. I think I had two cans that just stopped spraying, and simply oozed after using it once. It's a crappy product, and it doesn't last long before it starts sputtering.
  
  You say you have fine hair and are afraid of weighing it down. My hair also weighs down easily with product, and I love how dry shampoo seems to give it more body and oomph. I usually use it when I straighten my hair so I don't have to wash it and re-straighten it the next day. I don't use it multiple times in a row without washing my hair though since it will start to build up at that point and make your hair gross.
  
  EDIT: Also, although I haven't tried it, I've heard a lot of good things about Batiste. Unfortunately it's just not sold in stores in my area and I don't really feel like buying it online.
  
  EDIT 2: Something else I just thought of -- dry shampoo can sometimes make my scalp a bit itchy, so I don't know if it will affect your eczema at all.
