Pureology Pure Volume Shampoo 1L (33.8 fl.oz.)

I purchased this because it is advertised as being for flat, fine, color-treated hair....that'd be me! First, it was difficult to work it up into any kind of lather. But being sulfate-free, I really wasn't expecting lather. In place of a sulfate, it contains Disodium Laureth Sulfosuccinate. This isn't a sulfate even though the name leads you to believe it may be in the same class, it's not. It is used as a "gentler cleanser that won't strip your hair but won't strip moisture". Unfortunately, there seems to be an additional ingredient that doesn't allow the DLS to remove build up and rinse properly. Actually, it does just the opposite. I poured an adequate amount into my hand, then rubbed my hands together to start the 'lathering' process. All I created was a messy PASTE. Against my better judgement, I went to work it into my scalp. I ended up with what felt like wet, paste-like straw on my head. I couldn't even get my fingers through my hair. It coated my hair with a thick film that I couldn't rinse completely. How in the world could this be for my hair type?! Tossed out the remainder of the bottle. Thank goodness it was only the trial size! The only positive I can say about it is that it has a very nice scent.
