I'm not usually a conditioner person, as I find it makes my hair oily. But if you read my Shampoo review, that leaves my hair super dry so you do need a follow up conditioner - although I would say this isn't the most nourishing conditioner... my hair is rather knotty and feels a bit matted. I always buy matching Shampoo+Conditioner so i'm kinda stuck on this one!
I haven't noticed "thicker hair" - more volume yes, that may be the result of this conditioner being lighter weight, albeit less moisturising...
Worth a try. Might have to break my own rule use the shampoo with a different conditioner!
I have had the same results with ELVIVE Fibralogy Conditioner as with ELVIVE Fibralogy Shampoo. Pleasant to use unfortunately no significant results. I have been using the conditioner daily along with the shampoo. It smells lovely and feels silky. I would leave it on for 3 to 5 minutes. Once again It could be because my hair has always been on the fine side the results have not been considerable. Nevertheless I enjoyed being a part of trial team.
