Ohh, yes, since we are hair twins I think my opinion should get extra weight
Mine is actually a skosh looser than yours, but still similar. Fraternal twins perhaps.
Anyway, the amount of product scared me too. Remember it was just 4 months ago that I had straight hair. Most days I never used ANY product!
Anyway, my stylist showed me the amounts of product she was using when teaching me what to do, and it just looked like too much to me, so for the first few days I used a lot less. And my hair looked really bad. It just looked stringy and sad. So, thinking I was still using too much, I used even less, and it still didn't look good. In fact it looked worse. I tried taking all kinds of shortcuts, and nothing worked.
Then finally I decided to just do it as she suggested, and since then everything has been peachy.
After I finish working the product through, I cup and scrunch the wave into my hair until it dries completely, then tussle out the roots and finish off with a lightweight spray. The cup + scrunch motion helps encourage the wave into the ends, and the tussle-age gets rid of the hat hair effect. Since I effectively killed my wave a bit by straightening my hair for so long, it takes me more effort than it will probably take you. I think getting the roots fluffed out will be key for you. Your hair is mercifully thicker and fuller than mine so you don't need to worry about the ends--just the very top.
What I like is that if my hair starts to get droopy, I can quickly re-scrunch it in place. The product allows me to do that, and is amazingly not sticky or heavy...but the downside is that it's hard to find. If I ever left the vicinity of NYC, I'd have to order it online.
FWIW I admire your hair very much. It's so nice and evenly wavy. Mine waves in some places but not others...and it's always a tossup where it will wave each day...sigh.
