(sorry to interrupt this thread) I have the same feeling, and I haven't used the Marc Anthony product -- but I do have some good product suggestions.

I like using a volumizing mousse and/or a hair powder to give my hair grip and volume without a stitch of extra oiliness. I find that most thickening/styling creams tend to weigh my hair down, which makes my hair look fuller but fall flat later in the day. Root spray will do good things for me, but only in combination with something a little stronger.

I use a mousse nearly every time my hair is wet. If I want more volume or to do something when my hair is still squeaky-clean, I supplement with a powder/spray to give it the texture to hold. They are also good to fluff up your hair if/when it falls.

Favorite mousses:

• Drybar's Southern Belle mousse: Sort of a strong smell if you're sensitive to that. Volume, but I can run my hands through it. I've been using this every day.

• Kerastase Resistance Volumactive: Recommended by my hairdresser. The most powerful mousse I've used, with good hold. Doesn't leave your roots particularly soft but is volumizing magic (and is not usually this expensive).

• Aveda Phomollient - Leaves hair soft and full. This is the most minimal hold of the three.

• Runners-up: Bumble and bumble Full Form mousse (Works very well, runs out VERY quickly), Big Sexy Hair Root Pump Plus (Effective, but a little crunchy-feeling).

Hair powder:

• L'Oreal Professionel True Grip: Love this. My personal favorite. Lasts longer than you'd think, even though it's so small. Doubles as dry shampoo.

• Schwarzkopf Dust It: Works well for styling/pulling hair up. A little denser than the True Grip.

• Got2B Powderful: The cheapest, and it's magic. Also made by Schwarzkopf. Holds its own against the other two.

• Runner-up: Bumble and bumble Pret-a-Powder (pricy, smells good, soft... but just not as good as the others as a texturizer or dry shampoo).

Texturizing spray: This stuff, sprayed at the roots, will fluff up any hair, any time. Works well for volume and for getting styles to hold.

• HOLY GRAIL PRODUCT ALERT: Oribe Dry Texturizing Spray. Hold up hair, spray at roots, drop hair, roots stay up. Great for fluffing up a ponytail or boosting limp afternoon/next-day hair.

I'd recommend picking this stuff up! It' only about $5 and a little goes a long way. A dry shampoo might help too, but it wouldn't be quite as effective.
