I think what most people have a problem with is not necessarily the smell, but how strong it is. All Living Proof products have a citrusy aroma, the shampoos & conditioners lingering the least... But all of the styling products' scent hangs around for a while. While it's not an offensive smell in my opinion, it can irritate my nose when my allergies are acting up!
I still love their "Full" line though... I use the thickening cream daily!! Now, this product's fragrance has never bothered me in the slightest. Maybe because it's not a spray and won't fly up my nose... Have you tried it?
