Let's see what I can answer!
1. From what I understand, it will need more moisture (I started in June, so no personal experience). You can get this from heavier conditioners and some good DTs.
2. I used Suave clarifying to start and then HE drama clean when I had serious build-up issues. As long as it has a sulfate and no silicones, it will work.
3. What products are you using? I get this when I miss sections with my gel. I scrunch gel in with my head down, but have to flip it up to get my crown and canopy. That usually helps.
4. I use honey in ACV rinses and sometimes as a leave-in. Just be careful of how much you use, and don't mix with a gel, or you'll have crunch that won't scrunch out (this happened to me a few weeks ago... not cool!). When I use it as a leave-in, I plop with it for twenty min before scrunching in gel and diffusing. That lets it soak in a bit, I think.
5. I put a few tablespoons (I'm guessing, since I don't actually measure it) in a big cup. After using my rinse-out, I fill the cup with water and carefully pour down the length of my hair a few times. I usually use some honey in it. I know some people use squirt bottles, but my squirt bottle is reserved for baking soda!
6. I haven't tried re:coil
or tightly wound, so I cant comment on those. LOOB did nothing for me (and I think caused build-up). Right now I'm using FOTE and HEBE, but I've used SMU in the past. FOTE is the first thing to touch my hair after my leave-in. I use a gel on top of that after plopping, and that's been working well.
7. FOTE and CK help with humidity when I'm in Houston. I use them both under a good gel. Make sure you're getting equal distribution, especially in your canopy, since you hae problems with it.
FOTE gives me great clumps! Honey and ACV rinses also help.
The most important thing I do to prevent frizz is pixie-curling with a diffuser. Anything else (including air-drying) and my curls lack volume and clumpage, and are majorly frizzy. I've also been pineappling with a satin cap at night and that's helped.
You didn't mention why your hair didn't adjust to it. Most people have problems with greasiness and can't wait it out. Give it at least six weeks this time. There are things to help with problems you may encounter, and it takes time to figure out what works for you. Experiment and don't give up! The results are so worth it!
