I loooooove this mousse. I've been using it daily for about a week. The only thing I don't like about it is the dispenser. An upright aerosol, whyyyy? I have a feeling I'm going to be desperately trying to get out like the last 1/4 of the can, when I get there.
But other than that, this stuff straight up gives me Kate Middleton hair. I've been trying to achieve volume, body, control, AND softness when blowing out my fine, thin, flyaway-and-static-prone, balayage-highlighted hair. I used to have to combine a bunch of products, and I still didn't get the results I wanted, and my superfine hair would either be stiff/crunchy, or weighed down by hour 4 or 5 of the 'do, or both.
I was a little skeptical of this mousse because of the bad reviews here, so I took note of the complaints and did a few things differently:
1. Shook the can a lot before dispensing.
2. Dispensed half of the "egg size" they recommend on the can.
3. Applied from the crown down, then just used my fingers to just barely rub any excess into the roots.
4. Blowdried with a big round brush.
I agree that at first, your hair feels a little weird and filmy. Not weighed down, though. That first day, I was unsure if I liked it. I went ahead and curled the ends of my hair as usual and went to work. By noon, my hair is usually wilting. That day, at noon, my hair was still full of so much bounce and body, and the curls were still holding! I ran my fingers through my hair and it was like I had double the strands as usual.
Day 2, I used it in the exact same way, and here's where I ran into the greasy/flat problem. My hair still looked nice all day, but not as good as the first day.
Day 3, I used a clarifying shampoo instead of my regular shampoo, and BAM. Amazing hair.
So, I think what's going on with this mousse is that you really need to be sure your hair is relatively low on buildup if you want to use it. Having clarified, I got three days of continuous use of the mousse before needing to clarify again. For the record, it wasn't just this mousse building up; I use the Split End Mender (amaaaaazing) and a thermal protector cream (just L'Oreal, nothing fancy), and sometimes a leave-in conditioner (Verb), on the daily.
What I love most is that it somehow provides thickness, tons of body, AND control. I'm not constantly pushing flyaways out of my eyes anymore. And yes, it's expensive, but I use so little that I think it'll last a while.
